Prompt to access their registries. Licensing What Do I Do If My Existing License Key Is Expired? Users may obtain additional, temporary license keys from the OpenLink web site. Users proceed through the downloads matrix and stop, when they are presented with the product download links. Licenses are mailed to users, before they click the actual links to obtain the software. Licensing What Do I Tell Users Who Want New Temporary Licenses? Users may repeat the downloads process—up to three times—to obtain new, temporary licenses. However, this option is inconvenient for many persons. Consequently, consultants may generate licenses with the license generators. Alternatively, consultants may ask the Account Manager to generate a temporary key. Licensing What Is A Concurrent Connection? A concurrent session is an open database session. Users often confuse database connections with perceived application connections. For example, Microsoft Access may appear to open one connection against the target database. However, Access really spawns 2 or more database sessions. This causes an unexpected number of licenses to be consumed. Users must understand that Access and other connections are coded to behave in this manner. Licensing What Is A Concurrent User? A concurrent user is a distinct ip address. Licensing What Is ASNPRINT.exe? ASNPRINT.exe is a diagnostic utility. It reads OpenLink 4.x and 5.x licenses, and displays the terms associated with those licenses. ASNPRINT.exe cannot read corrupt licenses. ASNPRINT.exe cannot read 1.x or 3.x licenses. Licensing What Licenses are provided? OpenLink provided non-expiring, evaluation licenses with 1.x and 3.x Multi-Tier software. Inform 1.x and 3.x users that OpenLink's latest components use a new licensing model. Then, send these users to Account Management for additional information. Licensing What are the UDA Licensing Model based on? Both Single-Tier and Multi-Tier license models are based on concurrent "users" and concurrent "connections." Open Database Connectivity (ODBC) What is Generic ODBC? OpenLink's ODBC Lite and Generic ODBC drivers perform a special function. These drivers enable users to establish ODBC connections to databases, for which OpenLink does not provide an agent. To proceed, users must possess native or 3rd party ODBC drivers that connect to their databases. Then, users must install OpenLink's ODBC Lite drivers on the machine, which contains these drivers. Multi-Tier users must install the Request Broker and Generic ODBC Agent on the machine, which contains these drivers. Multi-Tier users may install the Multi-Tier client on any supported operating system. Finally, OpenLink's ODBC Lite and Generic ODBC drivers proxy SQL requests from the application-through the 3rd party Data Source Name-to the actual database. Performance How can I bench-test OpenLink drivers? You can download OpenLink ODBC Bench to run TPC-A like and TPC-C like bench tests against OpenLink and non-OpenLink ODBC drivers. OpenLink Software also provide a OpenLink JDBC Bench to run TPC-A like bench tests against OpenLink and non-OpenLink JDBC drivers. Please feel free to contribute your results to the OpenLink Product Support team Performance How can I detect bottlenecks caused by OpenLink drivers? Download ODBC Scan to detect bottlenecks caused by OpenLink drivers.

Compatibility Can I mix and match client and server components from different OpenLink versions? OpenLink Software does not support mixed-version installations. Mismatched client and server software may not hinder a user's ability to connect and query. However, version incompatibility issues will arise over time. In fact, users who mix OpenLink 3.x and OpenLink 4.x software can expect specific problems with stability, transactions, and threading. These problems can only be resolved by upgrading the older component. Compatibility Can I run OpenLink 32-bit data access drivers (ODBC or JDBC) on a 64-bit operating system? OpenLink 32-bit data access drivers (ODBC or JDBC) software runs on 64-bit operating systems. However, OpenLink's 32-bit data access drivers are designed for use with 32-bit applications. Connectivity is possible to 64-bit applications that ship with 32bit libraries. However, OpenLink does not recommend this configuration. Compatibility Can I use 64-bit OpenLink ODBC or JDBC Drivers on a 32-bit operating system? OpenLink Software does not recommend this configuration. Compatibility Can I run multiple versions at the same time? Users like to run multiple driver versions for comparative purposes. Single-Tier users simply install their new drivers to a new directory. Multi-Tier drivers should install their new drivers to different directories, as well. In addition, Multi-Tier users must insure that their Request Brokers use separate TCP/IP Listen ports. Compatibility Do I need ODBC or JDBC Drivers? If you are unsure of whether you require our ODBC or JDBC drivers, please review the questions posed below: Do you need to query a database with a 3rd party application? Is your application ODBC- or JDBC- compliant? Does your network environment support the TCP/IP or SPX protocol? OpenLink's Data Access Drivers provide ODBC and JDBC connectivity between compliant applications and databases. Moreover, OpenLink's drivers use the TCP/IP network protocol to achieve this connection. Consequently, if your response is YES to the aforementioned questions, you need these drivers. If you are still unsure, please consult your Database Administrators, System Administrators, or other knowledgeable staff. Users who respond NO to one or more questions must clarify their needs with either a Support Consultant or their Account Manager. We offer other solutions which might be what you require. Compatibility Do OpenLink ODBC Drivers work with Oracle Heterogeneous Services? Our ODBC drivers work in conjunction with Oracle's Heterogeneous Services. Compatibility Do OpenLink ODBC Drivers work with SQLServer Linked Servers? OpenLink's 5.x+ drivers support ODBC API calls made by MS SQLServer's Linked Servers. We also provide an alternative OLE DB provider for use with this and similar products. Compatibility Does OpenLink ODBC Drivers work with the SQL Server DTS Wizard? OpenLink's 5.x+ drivers support ODBC API calls made by MS SQLServer's DTS Wizard. We also provide an alternative ODBC provider for ADO.NET and OLE.DB for use with this and similar products. Compatibility Do you have 16Bit drivers? OpenLink produced 16Bit 1.x builds. These builds are not available to the general public. Compatibility How can I tell if OpenLink produces software for a particular operating system or database? Go to

Users Need To Open On Their Firewalls To Use OpenLink Software? Single-Tier users should not need to open ports to accommodate the Single-Tier driver. However, ports may need to be opened to facilitate connections between the database native client and the database to which it connects. Multi-Tier users need to take the following action, if a firewall surrounds the machine that contains the Multi-Tier server components Configuration What Services Do Users Start To Use OpenLink Drivers? OpenLink Single-Tier users do not need to start services to use their drivers. Single-Tier users need to start the HTTP-Based iODBC Data Sources Administrator, if they want to use the graphical configuration utility. Use the following command to proceed: iodbc-admin-httpd.sh start OpenLink Multi-Tier users need to start their Request Brokers to use their drivers. Use the following command to start the Broker and the associated Administrative Assistant: oplrqb Configuration What Values Do Multi-Tier Users Need To Pass In Their Data-Sources? Multi-Tier users must pass the following values in their Multi-Tier DSNs: Server — Passes the hostname or IP address of the server on which the Multi-Tier Request Broker listens. Also passes the TCP port on which the Broker listens. The format is host:port. Domain — This value corresponds to a Domain Alias that appears in the [Domain Aliases] section of the Session Rules Book. Default Domain Aliases are named after the databases to which the database agent connect. Custom Domain Aliases may take any form. Database — This is the name of the database or Oracle SID. Login ID — This is a valid database username. Password — This is a valid database password. Configuration What Values Do Single-Tier Users Need To Pass In Their DataSources? All Single-Tier users must pass a valid Data Source Name. Configuration What Values Must I Pass In My Single-Tier DSN? UDA Support Primer Data Source Name (DNS) Creation What values must I pass in my Single-Tier DSN All Single-Tier users must pass a valid Data Source Name. Configuration What is the odbc.ini file? The odbc.ini file is a standard, ODBC client configuration file. It is not specific to OpenLink drivers. In fact, many systems may have a pre-existing odbc.ini file in /etc or another directory. Nevertheless, OpenLink components ship with their own odbc.ini file. It appears in the /bin sub-directory of Unix installations. odbc.ini contains a list of all the Data Sources that appear within. Configuration What values do I pass for my OpenLink environment variables? OpenLink's ODBC drivers recognize the following ODBC-specific environment variables. Users should not set ODBC variables manually. OpenLink's drivers ship with openlink.sh and openlink.csh files. These files appear in the root of the OpenLink installation. openlink.sh should be sourced if using Bourne or Bash shells. openlink.csh should be sourced in C shell. Configuration What values must I pass in my Multi-Tier DSN? You must pass the following values in your Multi-Tier DSN: Name A descriptive name that identifies the Data Source. Server Passes the hostname or IP address of the server on which.

Our OpenLink Single-Tier drivers. We recommend OpenLink's Multi-Tier drivers to evaluators in Category 2. Evaluators in Category 3 must install the OpenLink server components on their database server. NOTE:Evaluators in Category 2 may install the OpenLink server components on their database server or any machine, which contains the database native client. In this scenario, the OpenLink database agent can connect to the database through that database client. Please see the technical article on connecting via in a three-tier environment Features Do OpenLink ODBC Drivers Load Share when used in Active-Active Clusters? Our Multi-Tier drivers may be deployed in a load balancing architecture. Features Do OpenLink Drivers (ODBC or JDBC) function in Fail-over Cluster environments? Yes. OpenLink functions in Fail-over Cluster environments. Multi-Tier users must install one set of OpenLink server components (Request Broker & Database Agent) on each node. The fail-over Broker may be instantiated by shell scripts, cron, or some other startup procedure, when the active node goes down. Some environments may support multiple, running Request Brokers, so long as each Request Broker can bind to a unique IP address. Features Do OpenLink ODBC & JDBC drivers also provide data migration facilities? OpenLink's ODBC & JDBC drivers can be used in conjunction with 3rd-party data migration facilities. However, OpenLink's Virtuoso Server provides Snapshot Replication and a Virtual Database Repository. Virtuoso Snapshot Replication is similar to MS SQLServer's Data Transformation Services (DTS) Wizard. Virtuoso's Virtual Database Repository provides one with an interface and functionality similar to MS SQLServer's Linked Servers or Oracle's Heterogeneous Services. Features What Do Your Drivers Do? OpenLink's Data Access drivers enable users to establish ODBC, ADO.Net, OLEDB and JDBC connections between applications and databases. Applications use these connections to execute SQL queries against the data contained within the databases. Typical SQL queries select, insert, update, or delete data. Other queries add, modify, or delete the structures that contain the data. Features What Is The JDBC-ODBC Bridge? The JDBC-ODBC Bridge—or "Type 1" JDBC connection—allows users to establish connections to ODBC Data Source Names using a JDBC connection URL. The JDBC connection URL passes the name of a valid ODBC Data Source as a connection parameter Features What Is The ODBC-JDBC Bridge? OpenLink's ODBC-JDBC Bridge drivers allow ODBC Data Source Names to connect to JDBC connection URLs. This allows ODBC compliant applications to connect to and query JDBC data stores. Features What Is The ODBC-ODBC Bridge? OpenLink Software builds specific database agents for DB2, Informix, Ingres, MS SQLServer, MySQL, Oracle, PostgreSQL, Progress, and Sybase. However, many users have Access, Paradox, Btrieve, DBase, and other databases for which OpenLink does not build agents. The ODBC-ODBC Bridge enables users to connect OpenLink drivers to these databases. The Bridge proxies OpenLink driver connections through 3rd party drivers that already connect to the database. Installation Can I Install New Software On Top Of Existing Software? Users can install new software on top of existing software. However, this is not the preferred course of action, in many circumstances. Users should install new software

The OpenLink downloads pages to search for the software for your particular OS. If your Operating System or Database is not available in the list of supported platforms, please contact your Product Support consultant or Account Manager as the software might be available internally but not publicly so. Compatibility Is Older OS Compatibility Supported? Consultants will encounter users who possess older builds of popular operating systems. For example, OpenLink may provide software for Solaris 2.5 systems. However, users have Solaris 2.4. In this instance, consultants should not encourage users to download software. OpenLink's software is not backwards compatible and may not function on the older platform. Compatibility Is there Older DB Compatibility Supported? Consultants will encounter users who possess older builds of popular databases. For example, OpenLink may provide software for Informix 7.3 systems. However, users have Informix 5. In this instance, consultants should not encourage users to download software. OpenLink's software is not backwards compatible and may not function with the older platform. Be advised - Progress databases and OpenLink's Progress software are compatible, as long as both products share the same major number. For instance, OpenLink's Progress 8 database agents will connect to most Progress 8 databases. However Progress 8 database agents will not connect to Progress 7 databases. Compatibility OpenLink Data Access Drivers Vs iODBC? iODBC.org offers free installers and instructions for the open-source iODBC Driver Manager and iODBC SDK. The installers are packaged with source code, header files, make files, and other resources of interest to the development community. These products match OpenLink Software's quality and reliability; however, they, and the iODBC.org web site, cater to highly technical individuals who know how to build the iODBC Driver Manager into their own custom solutions. OpenLink Software provides commercial quality Data Access Drivers, the Virtuoso Universal Server, diagnostic utilities, and related SDKs. In addition, the iODBC Driver Manager is bundled into the OpenLink SDKs and installers for Data Access Drivers and Virtuoso. This software is intended to service businesses and other entities which need a complete, reliable, out-of-the-box solution. OpenLink provides value added components in the OpenLink iODBC variant of the iODBC SDK. This value takes the form of ready-to-run iODBC ports for all supported platforms, and in the case of Mac OS X this currently includes an AQUA and Frameworks based ODBC Administrator. Compatibility What Are Your Prerequisites And System Requirements? Users must install OpenLink's Single-Tier drivers on a supported operating system. Users must install DB2, Informix, Ingres, and Progress drivers on a machine, which contains a functional copy of their database native client. Users must install "ODBC Lite" drivers on a system that contains a 3rd party data source, which connects to the user's database. Users must install OpenLink's Multi-Tier client and server components on one or more supported operating systems. DB2, Informix, Ingres, and Progress users must install the server components on a system, which contains the user's database or database native client. Users must install "Generic ODBC" drivers on a system that contains a

Scripts (install.sh) in ASCII transfer mode. FTP all other files in binary. Installation How To Uncompress Files? OpenLink's products ship in a compressed file format: — .bin Binary Mac Classic — .dmg Disk Image Mac OS X — .hqx BinHex Mac Classic — .tar Compressed Archive Unix Decompress with install.sh — .taz GZIP Archive Unix Decompress with tar -xvfz or gunzip — .zip Zip File WinZip Decompress with WinZip Installation I cannot download software to the appropriate machine. What do I do? Network or security policies may restrict a user's ability to download software onto a machine. Installation What Do I Do With The License File? Windows Single-Tier users must copy the file to their Lite32 directories. Mac and Unix Single-Tier users must copy the files to the /bin sub-directory of their OpenLink installations. No additional action is needed. All Multi-Tier users must copy their licenses to the /bin sub-directory of the OpenLink installation. Then, Multi-Tier users must restart their Request Broker services. ALERT OpenLink's 1.x and 3.x licensing mechanism differs substantially from the current procedure. Single-Tier legacy license holders must transfer their license file to the /bin sub-directory of their OpenLink installation. Then, they must run the register.exe program. Multi-Tier legacy license holders must perform the following actions: Shutdown the OpenLink Request Broker; Transfer the license file to the /bin sub-directory of their server installation; Rename license name.ini to register.ini; Run register.ini; Restart the Request Broker Service. Installation What Happened To The JdbcJodbc_sv And Judbc_sv Agents? OpenLink's 1.x and 3.x Multi-Tier connections spawned a JDBC-specific agent (jodbc_sv, judbc_sv), which spawned a database-specific agent. OpenLink's newer drivers have incorporated the functionality of jodbc_sv and judbc_sv into the database agents. Hence, separate jodbc_sv and judbc_sv agents are no longer needed. Installation What Is The Proper Way To Perform An Upgrade? Single-Tier users should terminate active ODBC connections, which use OpenLink's drivers. All Single-Tier users should back up their licenses, and Unix Single-Tier users should back-up existing odbc.ini and openlink.ini files. Finally, Single-Tier users should proceed with their upgrades. Multi-Tier users should terminate active ODBC connections, which use OpenLink's drivers. Multi-Tier users should also stop their Request Broker services. All Multi-Tier users should back-up their license and oplrqb.ini files, and Unix Multi-Tier users should back-up their odbc.ini files. Finally, Multi-Tier users should proceed with their upgrades. What about upgrading driver name or installing new driver? Internal Is OpenLink Support Staff responsible for all user problems? OpenLink Support staff should endeavor to solve most problems. However, some problems are the domain of the user. OpenLink Support staff is not responsible for extensive custom development. Users must code their own applications or seek assistance from OpenLink's Professional Services team. Likewise, OpenLink staff is not responsible for user database and network administration. — Acceptable: Can you help me write a JDBC connection URL to connect my application to Informix? — Questionable: Can you help me write a JAVA program? — Acceptable: Can you help me establish an ODBC connection to Oracle? — Questionable: Can you

3rd party data source, which connects to the user's database. Users must install Virtuoso Universal Server client and server components on one or more supported operating systems. Users must install the iODBC Driver Manager, OpenLink ODBC Bench, and ODBC Scan on a supported client operating system. Some users may require a compiler and library linker, if they intend to develop ODBC compliant applications or re-link OpenLink's agents or Driver Manager. Compatibility What Is The Compatibility with A Newer DB? Users who possess newer builds of popular databases. For example, OpenLink may provide software for Sybase 11 systems. However, users have Sybase 12. In most instances, consultants should encourage users to download the closest match to their database version. OpenLink's software is upwards compatible and should function with the newer product. Be advised - Progress databases and OpenLink's Progress software are compatible, as long as both products share the same major number. For instance, OpenLink's Progress 8 database agents will connect to most Progress 8 databases. However Progress 7 database agents will not connect to Progress 8 databases. Compatibility What JDBC Connection Formats Do Multi-Tier Drivers Support? OpenLink's Multi-Tier drivers support Type 3 (DSN-Less) JDBC connections. Multi-Tier drivers also support a Type 3 ODBC-JDBC Bridge. Compatibility What JDBC Connection Formats Do Single-Tier Drivers Support? Single-Tier drivers support Type 1 (JDBC-ODBC Bridge) JDBC connections. They also provide ODBC-JDBC Bridge connectivity. Compatibility What Network Protocols Do You Support? OpenLink supports the TCP/IP and IPX/SPX protocols. Compatibility What Suitable Software Should Be Used? Get a uname -a from all machines on which software would be installed. Get the name of the database to which the user wants to connect. See if OpenLink has a matching machine and database installation or database installation media. If OpenLink has the requisite materials, OpenLink can build an agent. If OpenLink does not have the operating system or database, the user may need to consider a custom build. ALERT Users may use OpenLink's Generic ODBC drivers to connect to databases, for which no database agents exist. These users simply need an OpenLink-supported operating system, which contains 3rd-party drivers that connect to the database. Other users may benefit from Single-Tier or application server configuration Multi-Tier connections, when they have a common database on an uncommon operating system. This latter configuration requires the installation of the database native client on an OpenLink-supported O/S. Compatibility What is the Compatibility With Newer OS? Users who possess newer builds of popular operating systems. For example, OpenLink may provide software for Solaris 2.8 systems. However, users have Solaris 2.9. In this instance, consultants should encourage users to download the closest match to their operating system version. OpenLink's software is upwards compatible and should function on the newer platform. Configuration Do I need to configure my environment to support ODBC-ODBC Bridge connectivity? You need to insure that your 3rd party drivers connect to the target database. You need to insure that openlink.sh or openlink.csh is run on Unix machines that contain OpenLink Software. openlink.sh should be.

Of each of the URL parameters: /DSN - Local ODBC Data Source Name; /UID - Database Username; /PWD - Database Password; /READONLY - Read-write or read-only session mode. Here is a sample Single-Tier JDBC connection URL: jdbc:openlink://ODBC/DSN=Local Oracle ODBC Data Source/UID=scott/PWD=tiger Configuration What Do Users Need To Do To Configure Their Multi-Tier Drivers? Unix users need to insure that openlink.sh (Bourne/Bash) or openlink.csh (C) is executed in the appropriate shell. These shell scripts set environment variables that pertain to ODBC. They appear in both client and server components installations. Unix users need to run set or env to insure that the environment variables (ODBCINI, ODBCINSTINI, etc.) are actually set. All users need to insure that the appropriate [Environment] section of the ~/openlink/bin/oplrqb.ini file contains the correct environment variables. All users should uncomment and set the PortHigh parameter that appears in the [Protocol TCP] section of the ~/openlink/bin/oplrqb.ini file. PortHigh should equal PortLow + the number of concurrent connections alloted by the license + a few extra ports. All users need to start the Request Broker. The Request Broker is the oplrqb executable that appears in the /bin sub-directory of Multi-Tier server components installation. Configuration What Do Users Need To Do To Configure Their Single-Tier Drivers? Unix users need to insure that openlink.sh (Bourne/Bash) or openlink.csh (C) is executed in the appropriate shell. These shell scripts set environment variables that pertain to ODBC. Unix users need to run set or env to insure that the environment variables (ODBCINI, ODBCINSTINI, etc.) are actually set. Unix users need to insure that the appropriate [Environment] section of the ~/openlink/bin/openlink.ini file contains the correct environment variables. Windows users need to insure that their System and User PATH variables contain the OpenLink driver .dlls and database native client .dlls. (Database native client .dll's are not required for MySQL, PostgreSQL, SQLServer, or Sybase.) Windows users may need to set other System and User PATH variables depending on the database. For example, Progress users need to set PROGRESSINI and PROMSGS. Configuration What Does Count Stored Procedure Parameters In SQL Procedures Do? This applies to the Oracle data-source. "Count Stored Procedure Parameters" affects the output from SQLProcedures when "Custom Catalog Views" is enabled. When "Custom Catalog Views" is off, the NUM_INPUT_PARAMETERS, NUM_OUTPUT_PARAMETERS and NUM_RESULT_SETS columns of the SQLProcedures result set all contain -1. When "Custom Catalog Views" in on, "Count Stored Procedure Parameters" is enabled and an internal view, OPENLINK$SQL_PROCEDURES is used; when this is disabled, the internal view, OPENLINK$SQL_PROCS_NOCOUNT is used instead. The result set returned by SQL_PROCEDURES includes the number of input and output parameters for each procedure. The number of result sets is always -1 like the case when "Custom Catalog Views" is off, SQL_PROCS_NOCOUNT returns -1 for the NUM_INPUT_PARAMETERS, NUM_OUTPUT_PARAMETERS and NUM_RESULT_SETS columns. Configuration What Does Custom Catalog Views Do? "Custom Catalog Views" controls whether custom OpenLink views are used to return meta-data for some ODBC catalog functions. These custom views provide more meta-data than is normally available. To create and use them, the script

OpenLink Lite ODBC Drivers for Oracle 12c (32-bit) - CNET

Setting limits the amount of memory which must be allocated for a dataset cell to hold the retrieved value - the value is truncated to this length. The default limit is 60000 bytes. When deferred fetching is enabled, the complete SQL_LONGVARCHAR or SQL_LONGVARBINARY value can be fetched. Note that any value set via SQLSetStmtAttr(SQL_ATTR_MAX_LENGTH) takes precedence over the 'Max Long Data Length' value. Configuration What Does Max Rows Override Do? By specifying a value within this option, we specify the maximum number of rows to be returned by any given query as opposed to the actual value of rows contained within the table. Configuration What Does Multiplex Sessions Do? This determines the connection parallelization mode within the Informix database. Multiplex sessions are now enabled by default. Configuration What Does NoQuotedIdentifiers Do? The Option is use by the ODBC-JDBC bridge drivers to indicate a give JDBC driver does not support the quoted identifiers, which is required for Jet engine based products like MS Access. From Multi-Tier the environment variable is JET_NOSUPPORTOFQUOTEDIDENTIFIER=[YES|NO] Configuration What Does OCIPrefetchMemory Do? OCIPrefetchMemory and OCIPrefetchRows control parameters relating to the Oracle OCI's prefetching facility. However, use of this facility has been disabled in the OpenLink agent and Lite driver because of problems experienced with Oracle 8.x and indicator variables. To minimize server round trips and maximize performance, the OCI can prefetch result set rows when executing a query. This prefetching operates independently of OpenLink's prefetching facility. The OCI prefetching can be customized by setting two attributes, OCI_ATTR_PREFETCH_ROWS and OCI_ATTR_PREFETCH_MEMORY. The OCIPrefetchMemory and OCIPrefetchRows settings in the OpenLink setup dialogs map directly to these OCI attributes. OCIPrefetchMemory sets the memory allocated for rows to be prefetched. The application then fetches as many rows as will fit into that much memory. OCIPrefetchRows sets the number of rows to be prefetched. When both of these attributes are set, the OCI prefetches rows up to the OCIPrefetchRows limit, or until the OCIPrefetchMemory limit is reached, if this is lower. Configuration What Does OCIPrefetchRows Do? OCIPrefetchMemory and OCIPrefetchRows control parameters relating to the Oracle OCI's prefetching facility. However, use of this facility has been disabled in the OpenLink agent and Lite driver because of problems experienced with Oracle 8.x and indicator variables. To minimize server round trips and maximize performance, the OCI can prefetch result set rows when executing a query. This prefetching operates independently of OpenLink's prefetching facility.

Run in a Bourne or Bash shell. openlink.csh should be run in C shell. Configuration Do I need to configure my environment to support my JDBC connections? Insure that the CLASSPATH environment variable is set on the machine that contains your JDBC client application. CLASSPATH appears in the Windows System Utility (Control Panel). Windows users need to navigate to the portion of the utility that displays their User and System settings. Unix users may use echo to display their CLASSPATH setting. For example: bash$ echo $CLASSPATH /home/openlink/v51/mt/jdk1.4 CLASSPATH must pass the full path to an OpenLink JDBC opljdbc.jar, opljdbc2.jar, opljdbc3.jar or megathin.jar, megathin2.jar file depending on your JDK. Configuration Do users need to employ special configuration to operate in a firewalled environment? Single-Tier users should not need to open ports to accommodate the Single-Tier driver. However, ports may need to be opened to facilitate connections between the database native client and the database to which it connects. Multi-Tier users need to take the following action, if a firewall surrounds the machine that contains the Multi-Tier server components Configuration How Do I Assist A User Who Does Not Know What Values To Pass To His Or Her Variables? All database specific environment variables should appear in the database user's .profile (unix) or other, standard configuration file. Users may open these files to ascertain which values need to appear in their Single-Tier openlink.ini files and their Multi-Tier oplrqb.ini files. In fact, users should execute the database user's .profile before installing Single-Tier drivers or Multi-Tier server components. The installers will detect the variables and write them into the appropriate location. The standardized, ODBC and JDBC variables pass the following values:— CLASSPATH A JAVA client variable that passes the full path to an OpenLink JDBC .jar file.— LD_LIBRARY_PATH A generic library path variable that appends the full path to OpenLink's lib sub-directory.— LIBPATH An AIX library path variable that appends the full path to OpenLink's lib sub-directory.— ODBCINI Passes the full path to ~/openlink/bin/odbc.ini.— ODBCINSTINI Passes the full path to ~/openlink/bin/odbcinst.ini.— OPENLINKINI This Single-Tier variable passes the full path to ~/openlink/bin/openlink.ini.— PATH Appends the full path to OpenLink's bin sub-directory.— SHLIB_PATH An HP/UX library path variable that appends the full path to OpenLink's lib sub-directory.
