OpenLink Multi-tier Server Side Components (*nix) Aims and Intentions This guide is intended to enable competent system administrators to install and configure OpenLink Multi-tier client side components on *nix style operating systems in a few steps as possible.This guide does not explain any of the non-pertinent features encountered along the way. Such explanations may be found in the full documentation. Prerequisites You MUST be proficient in using a Unix shell. You MUST be proficient in using a Unix editor such as vi. You MUST have any required third party client libraries installed and configured. (Applicable to: DB2, Informix, Ingres, Oracle, Progress) Installation Log onto the machine and create a suitable OpenLink installation directory ($OPENLINK_INSTALL). Copy all relevant components to $OPENLINK_INSTALL. As a bare minimum, these will include the OpenLink Request Broker and OpenLink Database Agent for your respective target database. Install using the "install.sh" shell script -- #sh install.sh You should take care to enter correct information when prompted pertaining to ports, passwords, etc and ensure that you remember these for future use. The installation should finish without error. Licensing OpenLink Multi-tier licensing is handled on the server side so you should place the OpenLink license file (oplrqb.lic) in the $OPENLINK_INSTALL/bin directory.Configuration Many, supported target database types (MySQL, PostgreSQL, SQL Server, Sybase) require no further configuration, in which case you should move onto the next section.Other, supported target database types (DB2, Informix, Ingres, Oracle, Progress) do require additional environmental configuration in the OpenLink Request Broker session rule book ($OPENLINK_INSTALL/bin/oplrqb.ini)-- Edit the file $OPENLINK_INSTALL/bin/oplrqb.ini with a suitable text editor such as vi. Locate and edit the [Environment xxxxx] section where xxxxx matches your target database so as to ensure that any relevant environment variables pertaining you your system and target database are correct.NOTE: You may need to consult with your database administrator to verify these.The following example depicts an environment section for Oracle 10-- [Environment ORACLE100] ORACLE_HOME = /usr/instantclient_10_2 ;ORACLE_SID = ;ORACLE_SERVER = ;TWO_TASK = P: ;ODBC_CATALOGS = Y ; Uncomment after loading odbccat10.sql ;MULTIPLEX_LDA = 5 ; Allow 5 OpenLink clients on a single lda ;OPL_USR_TBLS_FIRST = Y ; Sort SQLTables starting with user tables SHOW_REMARKS = N ; Retrieve SQLColumns REMARKS field CURSOR_SENSITIVITY = LOW ; Set to HIGH after loading odbccat10.sql ;OCI_PREFETCH_ROWS = 100 ; Number of rows to prefetch ;OCI_PREFETCH_MEMORY = 65535 ; Amount of memory to use for prefetching LD_LIBRARY_PATH = /instantclient_10_2 ; Find shared libraries SHLIB_PATH = /instantclient_10_2 ; Find HP/UX shared libraries LIBPATH = /instantclient_10_2 ; Find AIX shared libraries ;NLS_LANG = AMERICAN_AMERICA.UTF8 ; Uncomment for Unicode connections Start the OpenLink Request Broker Starting in foreground debug modeIt is often best to initially start the Request Broker in (f)oreground (d)ebug in order to diagnose problems-- #cd $OPENLINK_INSTALL #. ./openlink.sh #oplrqb -fd OpenLink Request Broker Version 2.47 as of Tue Jan 08 2008 (Release 6.2 cvsid 00089).
