Summary :
This SAP Note outlines configuration guidelines for DB2 V9.1 database parameters, applicable to all SAP releases on Linux, UNIX, and Windows platforms. It specifies parameter settings for both OLTP and OLAP workload classes and provides setup details marked for DB2's Self Tuning Memory Manager (STMM) and based on the operating system, database bit version, and DB2 Fix Pack levels. STMM is recommended for automatic memory configuration in single partition systems. Modifications in parameters such as DISCOVER_DB, log settings, and memory thresholds are also documented. Users are advised not to alter these parameters unless necessary and to consult SAP Active Global Support for temporary deviations to resolve specific issues.
