Definitions
- the present invention relates generally to the management of a remote application connection to a data source. More particularly, the present invention relates to identifying a status corresponding to interactions between a remote application and a data source.
- Databases are computerized information storage and retrieval systems.
- a Relational Database Management System (RDBMS) is a database system which uses relational techniques for storing and retrieving data. Relational databases are organized into tables consisting of rows and columns of data.
- a database typically includes many tables, and each table includes multiple rows and columns.
- the tables are conventionally stored in direct access storage devices (DASD), such as magnetic or optical disk drives, for semi-permanent storage.
- DASD direct access storage devices
- SQL Structured Query Language
- ANSI American National Standards Institute
- ISO International Standards Organization
- a common application for databases relates to their interaction with Internet web browsers.
- a remote application such as a web browser may be used to query data from a data base. The data may then be used to create a table or other display of information on the web browser. This requires the transfer of data files and the formatting of data on the web browser.
- an interface module is required to enable interaction between the web browser and the database.
- Net.Data available from IBM Corp., Armonk, N.Y.
- Net.Data enables Internet and Intranet access to relational data on a variety of platforms.
- Net.Data incorporates a macrolanguage which supports both HTML and SQL and allows for interaction with universal web browsers and relational database systems.
- Net.Data operates in conjunction with a web server interface and supports client-side processing as well as server-side processing with languages such as Java, REXX, Perl and C++.
- Net.Data provides database connectivity to a variety of data sources including information stored in relational databases, flat files Java files, Perl files and the like.
- Net.Data may support a variety of operating systems, including OS/2, AIX, Windows NT, HP-UX, Solaris, SCO, OS/390 and OS/400. Net.Data is further able to cache web pages to improve application performance, particularly when repeated requests are made for the same web page. Although this invention is compatible for use with an interface module such as Net.Data, other common gateway interface applications may be used with the present invention as well.
- the interface module which may be resident on a server, receives a query from a web browser, formats the query into SQL, and interacts with the database to receive data and create the table or other display of information.
- the interface module uses its macrolanguage to present the data to the web browser in HTML format.
- the web browser displays the data to a user of the remote application.
- the interface module serves as an Internet gateway for accessing a database.
- the interface module every time the interface module connects to the database, requests a connection set up for the database, or sends a query to get data results from the data base, the interface must perform a set of time-consuming processes such as initialization, authorization, password confirmation, and the like. These processes can be time consuming, slowing down the entire system and process.
- the present invention solves many or all of the foregoing problems by introducing a system and method by which a plurality of remote applications can connect with a data source without having all communication pass through a simple connection manager.
- a system in one aspect of the invention, includes an interface module configured to interface with a remote application, a port module to interface between the interface module and the data source, and a connection manager module to facilitate the direct interface between the interface module and the port module.
- the connection manager may establish a connection between the connection manager and the port module.
- the port module reports its availability to the connection manager through this connection. This may be done by the connection manager retrieving a port module identifier, which identifies an available port module for connecting to the data source from a data structure. The port module identifier may then be passed to the interface module so that the interface module may connect directly to the port module, and thus, the data source.
- the system in one preferred embodiment is configured to support HTML and provide interfacing between the requesting application and the data source.
- the interface module may be configured to convert the command from the remote application to a structured query language format to support interfacing with the data source.
- a method for connecting a plurality of remote applications with a data source includes the steps of providing at least one interface module configured to interface with a remote application, providing at least one port module to interface between the interface module and the data source, and providing a connection manager to facilitate the interface between the interface module and the port module.
- the method further includes establishing a direct connection between the interface module and the port module.
- a port module identifier for an available port module may be returned to the interface module for direct connection between the interface module and the port module.

- connection manager 220 Instead of the connection manager 220 repeatedly having to communicate with each port module 222 and each interface module 208 involved with a data source query for multiple port modules 222 and interface modules 208 , the connection manager 220 simply tracks which port modules 222 are busy. When the interface module 208 requests a port module 222 for connection to the data source 210 , the connection manager 220 simply provides or identifies a location of an available port module 222 which can then communicate directly with the interface module. It will be appreciated by those of skill in the art that this configuration and method will eliminate information bottlenecks at the connection manager 220 .
- a remote application connects to a web server 206 to request information from a data source 210 which in one preferred embodiment is on the server side.
- a data source 210 which in one preferred embodiment is on the server side.
- the request must be converted into an SQL command.
- the request is sent to an interface module 208 which reads the request and formats it into an SQL command.
- Both the web server 206 and the interface module 208 may be resident on the server side. Further, the web server 206 or the interface module 208 may convert the remote application request into an SQL query.
- connection manager 220 determines an available port module 222 and returns the location of the port module 222 to the interface module 208 .
- the request may then be sent as an SQL command 230 to the data source 210 directly through the port module 222 .
- the data source 210 may be a database system 210 such as a relational database, but hierarchical and object-oriented databases are also within the scope of this invention.
- data sources may include JAVA or PERL applications.
- the interface module 208 is configured to be compatible with such data sources in a supporting transaction and command language.
- a database manager 232 receives the SQL command 230 and searches in the database 210 to retrieve query results 234 that satisfy the SQL command 230 .
- the query results 234 may include any number of various files stored in a database 210 including text, values, characters, integers, and the like.
- the database manager 232 passes the query results 234 to the interface module 208 through the appropriate port module 222 connection.
- the interface module 208 may pass the query results 234 in an HTML format through the web server 206 to the remote application, which may be used to create a web page 212 on a web browser 202 . This feature expedites retrieval of query results 214 and generation of the web page 204 .
- the interface module 208 is configured to be compatible with HTML as well as SQL transactions and commands 230 .
- the interface module 208 may be Net.Data, but one of skill in the art will appreciate that other computer gateway interfaces capable of supporting and interfacing HTML formats and SQL commands may be used as well.
- each port module is known by an associated database and port module identifier.
- a data structure 240 includes entries 242 containing the name of the data source 210 , a minimum number of port modules 222 associated with the data source 210 , and a maximum number of port modules 222 associated with the data source 210 .
- the data structure is a data source array 240 . It will be appreciated by those of skill in the art that any type of data structure or storage device may be used to store information of the type stored in the data source array 240 .
- a second data structure 244 indexes the data source array 240 and includes entries 246 containing data regarding each port module 222 associated with a particular data source 210 . Each entry identifies which data source each port module belongs to, the port module identifier, and a status, which states whether the port module is busy or available.
- the data structure 244 is a port module array 244 . It will be appreciated by those of skill in the art that any type of data structure or storage device may be used to store information of the type store in the port module array 244 .
- connection manager 220 returns a port module identifier of an available particular port module 222 to the interface module by checking the availability status for the port module 222 associated with the data source 210 that is the object of the data request or SQL command 230 .
- the availability status of a port module 222 may be determined by a number of factors.
- the minimum number of port modules, as stored in the data source array 240 are launched and available for connecting to an interface module 208 .
- Each port module 222 may be configured to refresh or restart itself after a predetermined period of time, or after a particular event, such as the occurrence of an error.
- each port module 222 is configured to know its availability status and continually report that status to the connection manager 220 for storage in the port module array 244 . It will be appreciated by those of skill in the art that in this configuration, the connection manager 220 need not initiate contact with the data source 210 every time a request or SQL command passed from the interface manager 208 . That would be time consuming, especially for data sources residing on main frames. Instead, the connection manager 220 need only determine the first port module 222 having an “available” status and pass the corresponding port module identifier to the interface module 208 for direct connection 226 .
- connection manager 220 determines the first available port module 222 .
- One such way includes storing the port module identifier for each available port module 222 in a queue (not shown).
- the queue may include a first-in-first out array. If the status of an “available” port module 222 changes, the associated port module identifier is removed from the queue. The connection manager 220 , need only check the queue of “available” port module identifiers to find an available port module 222 .
- connection manager 220 may be configured to launch additional port modules 222 up to the predetermined maximum number of port modules 222 for a particular data source 210 ; the number being stored in the data source array.
- arrays 240 , 244 may be accomplished in various ways using various data structures. It will further be appreciated that these arrays 240 , 244 or data structures 240 , 244 may be part of the connection manager 220 , the port module 222 , the interface module 208 , or may be a separate module, and still provide the necessary information to enable a direct connection 226 between the interface module 208 and the port module 222 after the manner of the present invention.
- communication between the interface module 208 , connection manager 220 , and the port module 222 may be subject to authentication as a security measure.
- the data source array 240 and/or the port module array 244 may also include user identification or password data for use in verifying or authenticated the relevant communications. It will further be appreciated that any such identification data may be part of a separate module, or hard coded into the system 200 .
- one preferred embodiment of the present invention includes an arbitrary set of parameters, which may be embodied as a log file 250 associated with the connection manager 220 and each port module 222 .
- Each log file 250 contains data 252 relating to the activity of the port module 222 and connection manager 220 to facilitate the tracking of data flow through the system 200 .
- the data 252 in each log file 250 may include, for example, the date, time, a previous SQL statement or request, a present SQL statement or request, a number of rows, a warning message, an error messages, a feature database schema, a number of records, and the like.
- each port module 222 will have a port module identifier and data source identifier, a user may track the how many, and what type of, SQL statements passed to the data source 210 . One may also determine the time of the last SQL statement or request to the data source 210 and other information at predetermined points in the process.
- Each port module 222 and the connection manager 210 writes to a log file 250 , which in one preferred embodiment is stored as a flat file.
- the log file 250 has a maximum storage capacity of one megabyte. Once the log file 250 is full, another log file 250 may be generated.
- the log file 250 in accordance with the present invention is dynamic.
- the data 252 stored in the log files 250 is continually updated as the system 200 operates. It will be appreciated by those of skill in the art that various sizes or types of files can be used to store the data 252 contained in the log files 250 . Of importance is the fact that the data 252 in the log files 250 is accessible to the remote application 202 .
- the log file 250 is configured such that a user at a remote location 202 can view the data 252 stored in the log files 250 on a screen, print out the data 252 , or send it to another application.
- the user of a remote application 202 may also determine which of predetermined types of data will be stored in the log files 250 .
- the user may set the log files 250 at a maximum level so that a maximus amount of data is stored in the log files 250 .

- the log file 250 stores a change in status of the data source 210 from active to inactive.
- the port module 222 knows whether the data source 210 was “down” the last time the port module 222 was connected to the interface module 208 .
- the connection manager 220 seeks to establish a connection with the data source 210 through the port module 222
- the port module 222 will check the last status of the data source 210 , to which it is assigned to determine whether the data source 210 was active or inactive. If the last detected status indicated that the data source was inactive or “down,” the port module 222 will reestablish a connection with the data source 210 .
- connection or reconnection between the port module 222 and the data source 210 may be transparent to the interface module 208 . If the data source 210 is down, then the port module 222 will send the interface module 208 an error message stating that the data source 210 is down. When the data source 210 becomes active or is otherwise accessible again, the entire system 200 does not have to stop and restart in order to reestablish a connection between the interface module 208 and the data source 210 . The port module 222 , because it knows that the data source 210 was down during its last connection, will reestablish a connection with the data source.
- connection manager 220 had to reinitialize, all of the part modules 222 attached to the connection manager 220 , even those whose connection to a respective data base was functioning fine, would reset, thus interrupting a data search.
- the port module 222 it is an advantage of the present invention for the port module 222 to be able to determine the last status of the data source 210 , and be able to reconnect to its data source 210 without the connection manager 220 having to reinitialize. This enhanced error recovery makes the system more reliable. Most importantly, users see the system as more reliable and less temperamental, requiring less interaction.

Abstract
Description
- This application is a divisional of application Ser. No. 09/612,534 filed on Jul. 7, 2000 for LIVE CONNECTION ENHANCEMENT FOR DATA SOURCE INTERFACE.
- 1. Field of the Invention
- The present invention relates generally to the management of a remote application connection to a data source. More particularly, the present invention relates to identifying a status corresponding to interactions between a remote application and a data source.
- 2. Relevant Technology
- Databases are computerized information storage and retrieval systems. A Relational Database Management System (RDBMS) is a database system which uses relational techniques for storing and retrieving data. Relational databases are organized into tables consisting of rows and columns of data. A database typically includes many tables, and each table includes multiple rows and columns. The tables are conventionally stored in direct access storage devices (DASD), such as magnetic or optical disk drives, for semi-permanent storage.
- Generally, users communicate with an RDBMS using a Structured Query Language (SQL) interface. The SQL interface allows users to create, manipulate, and query a database by formulating relational operations on the tables, either interactively, in batch files, or embedded in host languages such as C and COBOL. SQL has evolved into a standard language for RDBMS software and has been adopted as such by both the American National Standards Institute (ANSI) and the International Standards Organization (ISO).
- A common application for databases relates to their interaction with Internet web browsers. A remote application such as a web browser may be used to query data from a data base. The data may then be used to create a table or other display of information on the web browser. This requires the transfer of data files and the formatting of data on the web browser. As the database is responsive to SQL and a web browser requires an HTML format, an interface module is required to enable interaction between the web browser and the database. One example of such an interface module is Net.Data available from IBM Corp., Armonk, N.Y.
- Net.Data enables Internet and Intranet access to relational data on a variety of platforms. Net.Data incorporates a macrolanguage which supports both HTML and SQL and allows for interaction with universal web browsers and relational database systems. Net.Data operates in conjunction with a web server interface and supports client-side processing as well as server-side processing with languages such as Java, REXX, Perl and C++. Net.Data provides database connectivity to a variety of data sources including information stored in relational databases, flat files Java files, Perl files and the like.
- Net.Data may support a variety of operating systems, including OS/2, AIX, Windows NT, HP-UX, Solaris, SCO, OS/390 and OS/400. Net.Data is further able to cache web pages to improve application performance, particularly when repeated requests are made for the same web page. Although this invention is compatible for use with an interface module such as Net.Data, other common gateway interface applications may be used with the present invention as well.
- The interface module, which may be resident on a server, receives a query from a web browser, formats the query into SQL, and interacts with the database to receive data and create the table or other display of information. The interface module then uses its macrolanguage to present the data to the web browser in HTML format. The web browser, in turn, displays the data to a user of the remote application. In this manner, the interface module serves as an Internet gateway for accessing a database. However, every time the interface module connects to the database, requests a connection set up for the database, or sends a query to get data results from the data base, the interface must perform a set of time-consuming processes such as initialization, authorization, password confirmation, and the like. These processes can be time consuming, slowing down the entire system and process.
- One attempt to overcome the problem of slower connections was to create a database manager to assist in synchronizing the connection of the interface modules with various ports of the database. However, in order to accommodate numerous web browsers, multiple applications of an interface module may be running, which may complicate the system. With increased use and complication, the system may be difficult to debug when a problem arises. Additionally, because everything runs through a connection manager, there are often miscommunications, synchronization problems, and bottlenecks between the user applications and the database.
- If other databases were static and the data source became inactive or went down for whatever reason, the data manager would not be able to tell when the data source became active again. Thus, subsequent queries would still detect an inactive data source. In order to establish another connection with the data source, the whole system would have to be reinitialized. In situations where the data manager managed multiple users, this reinitialization would affect remote users whose connection to a data base was functioning normally.
- Thus, it would be an advancement in the art to provide a system and method for connecting a plurality of remote applications with a data source in a simplified way.
- It would be a further advancement in the art to provide such a system and method which would remove the likelihood of bottleneck by removing the necessity of routing every communication between the interface module and data source through the connection manager.
- It would be a further advancement in the art to provide such a system and method that was dynamic and reliable and did not have to reinitialize if the data source became inactive or “went down.”
- Such an apparatus and method in accordance with the present invention is disclosed and claimed herein.
- The present invention solves many or all of the foregoing problems by introducing a system and method by which a plurality of remote applications can connect with a data source without having all communication pass through a simple connection manager.
- In one aspect of the invention, a system includes an interface module configured to interface with a remote application, a port module to interface between the interface module and the data source, and a connection manager module to facilitate the direct interface between the interface module and the port module. The connection manager may establish a connection between the connection manager and the port module. In one preferred embodiment, the port module reports its availability to the connection manager through this connection. This may be done by the connection manager retrieving a port module identifier, which identifies an available port module for connecting to the data source from a data structure. The port module identifier may then be passed to the interface module so that the interface module may connect directly to the port module, and thus, the data source.
- The system in one preferred embodiment is configured to support HTML and provide interfacing between the requesting application and the data source. The interface module may be configured to convert the command from the remote application to a structured query language format to support interfacing with the data source.
- In another aspect of the invention, a method for connecting a plurality of remote applications with a data source includes the steps of providing at least one interface module configured to interface with a remote application, providing at least one port module to interface between the interface module and the data source, and providing a connection manager to facilitate the interface between the interface module and the port module. In a preferred embodiment, the method further includes establishing a direct connection between the interface module and the port module. A port module identifier for an available port module may be returned to the interface module for direct connection between the interface module and the port module.
- Thus, it is an object of the invention to provide for the management of the connection between remote applications and a data source which alleviates bottlenecks in the data flow. It is another object of the invention to simplify the connection process by reducing the steps in the connection process. It is yet another object of the invention to reduce the need to synchronize each module used in the connection process.
- These and other objects, features, and advantages of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

- Certain preferred embodiments of a system in accordance with the invention are now described with reference to the FIGS.1-8, where like reference numbers indicate identical or functionally similar elements. The components of the present invention, as generally described and illustrated in the Figures, may be implemented in a wide variety of configurations. Thus, the following more detailed description of the embodiments of the system and method of the present invention, as represented in the FIGS. 1-8, is not intended to limit the scope of the invention, as claimed, but is merely representative of presently preferred embodiments of the invention.
- Various components of the invention are described herein as “modules.” In various embodiments, the modules may be implemented as software, hardware, firmware, or any combination thereof. For example, as used herein, a module may include any type of computer instruction or computer executable code located within a memory device and/or transmitted as electronic signals over a system bus or network. An identified module may, for instance, comprise one or more physical or logical blocks of computer instructions, which may be organized as an object, procedure, function, or the like.
- Nevertheless, the identified modules need not be located together, but may comprise disparate instructions stored in different locations, which together implement the described functionality of the module. Indeed, a module may comprise a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices.
- As used herein, the term executable code, or merely “executable,” is intended to include any type of computer instruction and computer executable code that may be located within a memory device and/or transmitted as electronic signals over a system bus or network. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be located together, but may comprise disparate instructions stored in different locations which together comprise the module and achieve the purpose stated for the module. Indeed, an executable may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices.
- Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure to be used, produced, or operated on during execution of an executable. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may at least partially exist merely as electronic signals on a system bus or network.
- FIG. 1 is a schematic block diagram illustrating a
computer system 10 in which a plurality of modules may be hosted on one ormore computer workstations 12 connected via anetwork 14. Thenetwork 14 may comprise a wide area network (WAN) or local area network (LAN) and may also comprise an interconnected system of networks, one particular example of which is the Internet. - A
typical computer workstation 12 may include a central processing unit (CPU) 16. TheCPU 16 may be operably connected to one ormore memory devices 18. Thememory devices 18 are depicted as including a non-volatile storage device 20 (such as a hard disk drive or CD-ROM drive), a read-only memory (ROM) 22, and a random access memory (RAM) 24. - Preferably, the
computer workstation 12 operates under the control of an operating system (OS) 25, such as OS/2®, WINDOWS NT®, WINDOWS®, UNIX®, and the like. In one embodiment, theOS 25 may provide a graphical user interface (GUI) to enable the user to visually interact with the modules of the present invention. In one embodiment, theOS 25 may be loaded from thenon-volatile storage device 20 into theRAM 24 at the time theworkstation 12 is booted. - The
workstation 12 may also include one ormore input devices 26, such as a mouse and/or a keyboard, for receiving inputs from a user. Similarly, one ormore output devices 28, such as a monitor and/or a printer, may be provided within, or be accessible from, theworkstation 12. - A
network interface 30, such as an Ethernet adapter, may be provided for coupling theworkstation 12 to thenetwork 14. In one embodiment, theworkstations 12 may be coupled to thenetwork 14 via a distributed remote data architecture (DRDA). Where thenetwork 14 is remote from theworkstation 12, thenetwork interface 30 may comprise a modem, and may connect to thenetwork 14 through a local access line, such as a telephone line. - Within any given
workstation 12, asystem bus 32 may operably interconnect theCPU 16, thememory devices 18, theinput devices 26, theoutput devices 28, thenetwork interface 30, and one or moreadditional ports 34, such as parallel and serial ports. - The
system bus 32 and anetwork backbone 36 may be regarded as data carriers. Accordingly, thesystem bus 32 and thenetwork backbone 36 may be embodied in numerous configurations, such as wire and/or fiber optic lines, as well as electromagnetic channels using visible light, infrared, and radio frequencies. - In general, the
network 14 may comprise a single local area network (LAN), a wide area network (WAN), several adjoining networks, an Intranet, an Extranet, or, as in the manner depicted, a system of interconnected networks such as theInternet 40. Theindividual workstations 12 may communicate with each other over thebackbone 36 and/or over theInternet 40 using various communication techniques. - For instance, different communication protocols, e.g., ISO/OSI, IPX, TCP/IP, may be used within the
network 14. In the case of theInternet 40, however, a layered communications protocol (i.e. TCP/IP) generally best enables communications between thediffering networks 14 andworkstations 12. - The
workstations 12 may be coupled via thenetwork 14 toapplication servers 42, and/or other resources orperipherals 44, such as scanners, printers, digital cameras, fax machines, and the like. External networks, may be coupled to thenetwork 14 through arouter 38 and/or through theInternet 40. - Referring now to FIG. 2, a data source
connection management system 200 of the present invention is shown. In one embodiment, aweb browser 202, is part of acomputer station 204. Thework station 204 may contain a plurality of modules (not shown) containing executable code and operational data suitable for operation within thememory devices 18 of FIG. 1. Of course, thememory devices 18 in which the modules of the present invention are located may also be distributed across both local and remote computer workstations 12 (FIG. 1). Likewise, two or more illustrated modules may be integrated into a single module without departing from the scope of the invention. - The present invention may be used over the
Internet 40 in conjunction with aconventional web browser 202. Theweb browser 202 interprets HTML documents and formats and definesweb pages 204. Theweb browser 202 may be at a remote workstation 12 (FIG. 1) and may be connected through theInternet 40 to aweb server 206. Theweb server 206 stores HTML documents and interacts with theweb browser 202 for downloading and uploading the documents for generation ofweb pages 212. - By way of example, a user at a remote application such as a
web browser 202, may want to search for a book on a book store web server via the Internet. Theweb browser 202 connects to theserver 206. Theserver 206 invokes aninterface module 208, which allows the remote user to specify a keyword in a book title for example. Theinterface module 208 will pass the request to adata source 210 and receive data in return in the form of a data file. The file can then be used to create aweb page 212 either at theserver 206 or at the remote user'sweb browser 202. - Referring now to FIG. 3, the
system 200 of the present invention includes aconnection manager 220. Theconnection manager 220 is a module that may include any type of computer instruction or computer executable code located within a memory device and/or transmitted as electronic signals over a system bus or network. It may comprise one or more logical blocks of computer instructions, which may be organized as an object, procedure, function, or the like. In one preferred embodiment, theconnection manager 220 is running in the background on theserver 206. - The
connection manager 220 is also configured to interface with at least oneinterface module 208. The connection manager is preferably located at a predetermined address to allow theinterface module 208 to readily connect to theconnection manager 220. Eachinterface module 208 in also configured to interface with aremote application 202 which may be a web browser connected to theinterface module 208 through theInternet 40. - The
connection manager 220 also interfaces with a plurality ofport modules 222. Eachport module 222 may be associated with one ormore data sources 210 and is identified by a port module identifier and thedata source 210 with which it is associated. Theport module 222,connection manager 220, andinterface module 208 may each have their own separate executable code. In a presently preferred embodiment, each of theport modules 222,connection manager 220, andinterface modules 208 communicate with each other using TCP/IP protocol, which allows the present invention to be easily transported between various operating system platforms such as Unix, OS, or Windows. - The
interface module 208 seeks aconnection 224 with theconnection manager 220 at the predetermined connection manager address. As will be discussed in greater detail below, theconnection manager 220 will determine whichdata sources 210 are available to theremote application 202 and whichport modules 222 are associated with eachdata source 210. Theconnection manager 220 will identify aport module 222 that is active, but not currently busy operating as the port or gateway to the database for aninterface module 208. Theconnection manager 220 will return the port module identifier to theinterface module 208 to allow theinterface module 208 to establish adirect connection 226 withport module 222 and thus, thedata source 210. - Instead of the
connection manager 220 repeatedly having to communicate with eachport module 222 and eachinterface module 208 involved with a data source query formultiple port modules 222 andinterface modules 208, theconnection manager 220 simply tracks whichport modules 222 are busy. When theinterface module 208 requests aport module 222 for connection to thedata source 210, theconnection manager 220 simply provides or identifies a location of anavailable port module 222 which can then communicate directly with the interface module. It will be appreciated by those of skill in the art that this configuration and method will eliminate information bottlenecks at theconnection manager 220. - Referring now to FIG. 4, a remote application connects to a
web server 206 to request information from adata source 210 which in one preferred embodiment is on the server side. For most data sources, the request must be converted into an SQL command. The request is sent to aninterface module 208 which reads the request and formats it into an SQL command. Both theweb server 206 and theinterface module 208 may be resident on the server side. Further, theweb server 206 or theinterface module 208 may convert the remote application request into an SQL query. - The
connection manager 220 then determines anavailable port module 222 and returns the location of theport module 222 to theinterface module 208. The request may then be sent as anSQL command 230 to thedata source 210 directly through theport module 222. In one embodiment, thedata source 210 may be adatabase system 210 such as a relational database, but hierarchical and object-oriented databases are also within the scope of this invention. In other preferred embodiments, data sources may include JAVA or PERL applications. In embodiments where data sources other than relational databases are used, theinterface module 208 is configured to be compatible with such data sources in a supporting transaction and command language. - A
database manager 232, such as DB2 manufactured by International Business Machines, receives theSQL command 230 and searches in thedatabase 210 to retrievequery results 234 that satisfy theSQL command 230. The query results 234 may include any number of various files stored in adatabase 210 including text, values, characters, integers, and the like. Once the query results 234 are retrieved, thedatabase manager 232 passes the query results 234 to theinterface module 208 through theappropriate port module 222 connection. Theinterface module 208 may pass the query results 234 in an HTML format through theweb server 206 to the remote application, which may be used to create aweb page 212 on aweb browser 202. This feature expedites retrieval of query results 214 and generation of theweb page 204. - Accordingly, the
interface module 208 is configured to be compatible with HTML as well as SQL transactions and commands 230. In one embodiment, theinterface module 208 may be Net.Data, but one of skill in the art will appreciate that other computer gateway interfaces capable of supporting and interfacing HTML formats and SQL commands may be used as well. - Referring now to FIGS. 4, 5, and6, each port module is known by an associated database and port module identifier. In one embodiment, a
data structure 240 includesentries 242 containing the name of thedata source 210, a minimum number ofport modules 222 associated with thedata source 210, and a maximum number ofport modules 222 associated with thedata source 210. In one presently preferred embodiment, the data structure is adata source array 240. It will be appreciated by those of skill in the art that any type of data structure or storage device may be used to store information of the type stored in thedata source array 240. - A
second data structure 244 indexes thedata source array 240 and includesentries 246 containing data regarding eachport module 222 associated with aparticular data source 210. Each entry identifies which data source each port module belongs to, the port module identifier, and a status, which states whether the port module is busy or available. - In a preferred embodiment, the
data structure 244 is aport module array 244. It will be appreciated by those of skill in the art that any type of data structure or storage device may be used to store information of the type store in theport module array 244. - The
connection manager 220 returns a port module identifier of an availableparticular port module 222 to the interface module by checking the availability status for theport module 222 associated with thedata source 210 that is the object of the data request orSQL command 230. The availability status of aport module 222 may be determined by a number of factors. Upon initialization of theconnection manager 220, the minimum number of port modules, as stored in thedata source array 240 are launched and available for connecting to aninterface module 208. - Once a
port module 222 is connected to aninterface module 208, thatport module 222 is no longer available and its status changes to busy or unavailable. Once abusy port module 222 is no longer occupied by aninterface module 208, its status is updated from busy to available and passed along to the connection manager for storage in the portmodule data structure 244. Eachport module 222 may be configured to refresh or restart itself after a predetermined period of time, or after a particular event, such as the occurrence of an error. - In a presently preferred embodiment, each
port module 222 is configured to know its availability status and continually report that status to theconnection manager 220 for storage in theport module array 244. It will be appreciated by those of skill in the art that in this configuration, theconnection manager 220 need not initiate contact with thedata source 210 every time a request or SQL command passed from theinterface manager 208. That would be time consuming, especially for data sources residing on main frames. Instead, theconnection manager 220 need only determine thefirst port module 222 having an “available” status and pass the corresponding port module identifier to theinterface module 208 fordirect connection 226. - It will be appreciated by those of skill in the art that there are many ways for
connection manager 220 to determine the firstavailable port module 222. One such way includes storing the port module identifier for eachavailable port module 222 in a queue (not shown). In one preferred embodiment, the queue may include a first-in-first out array. If the status of an “available”port module 222 changes, the associated port module identifier is removed from the queue. Theconnection manager 220, need only check the queue of “available” port module identifiers to find anavailable port module 222. - In one preferred embodiment, the
connection manager 220 may be configured to launchadditional port modules 222 up to the predetermined maximum number ofport modules 222 for aparticular data source 210; the number being stored in the data source array. - It will be appreciated by those of skill in the art that the storage of information such as that stored in the
arrays arrays data structures connection manager 220, theport module 222, theinterface module 208, or may be a separate module, and still provide the necessary information to enable adirect connection 226 between theinterface module 208 and theport module 222 after the manner of the present invention. - In one preferred embodiment, communication between the
interface module 208,connection manager 220, and theport module 222 may be subject to authentication as a security measure. It will be appreciated by those of skill in the art that thedata source array 240 and/or theport module array 244 may also include user identification or password data for use in verifying or authenticated the relevant communications. It will further be appreciated that any such identification data may be part of a separate module, or hard coded into thesystem 200. - Referring now to FIG. 7, one preferred embodiment of the present invention includes an arbitrary set of parameters, which may be embodied as a
log file 250 associated with theconnection manager 220 and eachport module 222. Eachlog file 250 containsdata 252 relating to the activity of theport module 222 andconnection manager 220 to facilitate the tracking of data flow through thesystem 200. Thedata 252 in eachlog file 250 may include, for example, the date, time, a previous SQL statement or request, a present SQL statement or request, a number of rows, a warning message, an error messages, a feature database schema, a number of records, and the like. Because eachport module 222 will have a port module identifier and data source identifier, a user may track the how many, and what type of, SQL statements passed to thedata source 210. One may also determine the time of the last SQL statement or request to thedata source 210 and other information at predetermined points in the process. - It will be appreciated by those of skill in the art that this information would facilitate debugging the
system 200. For example, users at aremote application 202 that may be creating or programming a web page that utilizes data stored at adata source 210 may check the log files 250 to track down an error in the application. - Each
port module 222 and theconnection manager 210 writes to alog file 250, which in one preferred embodiment is stored as a flat file. In a presently preferred embodiment, thelog file 250 has a maximum storage capacity of one megabyte. Once thelog file 250 is full, anotherlog file 250 may be generated. Thelog file 250 in accordance with the present invention is dynamic. Thedata 252 stored in the log files 250 is continually updated as thesystem 200 operates. It will be appreciated by those of skill in the art that various sizes or types of files can be used to store thedata 252 contained in the log files 250. Of importance is the fact that thedata 252 in the log files 250 is accessible to theremote application 202. - The
log file 250 is configured such that a user at aremote location 202 can view thedata 252 stored in the log files 250 on a screen, print out thedata 252, or send it to another application. The user of aremote application 202 may also determine which of predetermined types of data will be stored in the log files 250. The user may set the log files 250 at a maximum level so that a maximus amount of data is stored in the log files 250. The user may also set the log files 250 to store a minimum level of data. It will be appreciated by those of skill in the art that thesystem 200 will run more efficiently when the amount ofdata 252 stored in thelog file 250 is set to a minimal level. - In one preferred embodiment, the
log file 250 stores a change in status of thedata source 210 from active to inactive. Thus, theport module 222 knows whether thedata source 210 was “down” the last time theport module 222 was connected to theinterface module 208. When theconnection manager 220 seeks to establish a connection with thedata source 210 through theport module 222, theport module 222 will check the last status of thedata source 210, to which it is assigned to determine whether thedata source 210 was active or inactive. If the last detected status indicated that the data source was inactive or “down,” theport module 222 will reestablish a connection with thedata source 210. - The connection or reconnection between the
port module 222 and thedata source 210 may be transparent to theinterface module 208. If thedata source 210 is down, then theport module 222 will send theinterface module 208 an error message stating that thedata source 210 is down. When thedata source 210 becomes active or is otherwise accessible again, theentire system 200 does not have to stop and restart in order to reestablish a connection between theinterface module 208 and thedata source 210. Theport module 222, because it knows that thedata source 210 was down during its last connection, will reestablish a connection with the data source. - One of skill in the art will appreciate that if the
connection manager 220 had to reinitialize, all of thepart modules 222 attached to theconnection manager 220, even those whose connection to a respective data base was functioning fine, would reset, thus interrupting a data search. Thus, it is an advantage of the present invention for theport module 222 to be able to determine the last status of thedata source 210, and be able to reconnect to itsdata source 210 without theconnection manager 220 having to reinitialize. This enhanced error recovery makes the system more reliable. Most importantly, users see the system as more reliable and less temperamental, requiring less interaction. - Referring to FIG. 8, a flow diagram300 which incorporates one embodiment of a method of use of the
system 200 of FIGS. 2-7. Instep 302, the method begins. A remote application, such as theweb browser 202 requests data from adata source 210. The request may be sent over theInternet 40 to theweb server 206, which provides 304 theinterface module 208 which translates the request into a suitable search command such as SQL. - The
connection manager 220 is initialized 306 for communication with theinterface module 208. Theconnection manager 220 identifies 308 and stores the location of theport modules 222 associated with aparticular data source 210. Theport modules 222 serve as the connection port to thedata source 210 for theinterface module 208. Theconnection manager 210 facilitates the communication between theinterface module 208 and theconnection manager 220. Theconnection manager 220 establishes a connection with theport module 222 and determines 310 whether theport module 222 is available. Eachport module 222 is associated with aparticular data source 210 and identified by a port module identifier, which are each stored in a suitable data structure. A port module identifier for anavailable port module 222 is returned 312 to theinterface module 208. A direct connection is established 214 between theinterface module 208 and theport module 222. - In one preferred embodiment, the connections between the
interface module 208, theconnection manager 220, and theport module 222 are authorized to facilitate secured communications. - The
request 314 converted into SQL is passed to thedata source 210 and the retrieveddata 316 is inserted 318 into an HTML format to support interfacing between theremote application 202 and thedata source 210. The method may then be repeated 320 for additional data source requests or queries. If there are no further requests, theremote application 202 disconnects from theserver 206 and the method terminates 322. - In one embodiment, an arbitrary set of user-selectable parameters reflects a status of the connection between the remote application and the data source. These parameters may include a present SQL request, a warning message, an error message, a date, a time, a previous SQL request, a feature database schema, and/or a number of records. Data associated with these parameters may be passed to a
log file 250 at various stages in the process. In one preferred embodiment, the data is transmitted 324 to thelog file 250 according to condition selected by a user. For example, the user may want to maximize efficiency in the process by limiting the fields or parameters of data sent to the log file. On the other hand, the user may want to obtain as much information as possible in order to better debug the system or track data flow in greater detail. - Transmitting324 the data associate with the parameters to the
log file 250 may be performed at various times throughout themethod 300. Accordingly, the step of transmitting 324 may be identified as a sub-step 324 which may be performed after or in conjunction with other steps of themethod 300. Thus, transmitting 324 is illustrated in FIG. 8 at more than one location for illustrative purposes only. One of skill in the art will appreciate that the step of transmitting 324 may be performed at any number of locations in themethod 300. - In one preferred embodiment, the data stored in correlation with the arbitrary set of parameters is arranged in a hierarchical relation. At least one parameter of the arbitrary set of parameters corresponds to an output device selected by a user. For example, the user may select to view the data in the
log file 250 on the screen or by sending it to a printer. - The invention provides for the management of the connection between remote applications and a data source which alleviates bottlenecks in the data flow. The system and method of the present invention simplifies the connection between the remote application and the data source process by reducing the steps in the connection process. The system and method of the present invention eliminates the need to continually synchronize the
interface module 208 with theport module 222 for eachdata source 210 request. The invention may be readily adapted to existing software applications such as web browsers, web servers, database management systems, operating systems and other modules disclosed herein. - The present invention may be embodied in other specific forms without departing from its scope or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
