Sample Instance Configuration Parameters

Tuning Oracle Database 24-11 ■ Collect routine statistics and report by using Oracle Database Enterprise Manager EM, which is available in Oracle Database 11g as a standard offering. – Routine Statistics Gathering Routine statistics gathering can be taken care by the Automated Maintenance Tasks, which is available in the following navigation path in Oracle Database 11g: Oracle EM , the Server tab, Query Optimizer, Manage Optimizer Statistics, the Automated Maintenance Tasks link – Reporting requirements of statistics through Oracle Database 11g EM To report on the state of the currently gathered statistics, EM provides a reporting interface in the following navigation path: Oracle EM , the Server tab, Query Optimizer, Manage Optimizer Statistics, the Object Statistics link This interface can be used for the reporting purpose for All Objects of the Schema or even the Object of choice, which have Stale, Missing, or Locked states or are already analyzed. ■ Collect complete schema statistics upon implementation of Oracle Identity Manager. Update schema statistics regularly, so that the Cost-Based Optimizer CBO can access the latest statistics. You must consider complete schema or table statistics on mass data change events such as bulkload of users or accounts, import of a new connector, a huge reconciliation run from a new target system, or use of an archival utility. This helps the CBO determine an efficient query execution plan that is based on the current state of data. The following is a sample SQL command to collect database statistics on a regular basis: DBMS_STATS.GATHER_SCHEMA_STATSOWNNAME= schema_owner, ESTIMATE_PERCENT=DBMS_STATS.AUTO_SAMPLE_SIZE, DEGREE=8, OPTIONS=GATHER AUTO, NO_INVALIDATE=FALSE; ■ Look for relevant recommendations provided in advisory sections in the Automatic Database Diagnostic Monitor ADDM or Automatic Workload Note: You can use Oracle Enterprise Manager Fusion Middleware Control to monitor Oracle Identity Manager. To do so: 1. Under Identity Management, select Oracle Identity Manager to go to the home page. On the Home page, you can monitor Oracle Identity Manager. 2. From the Oracle Identity Manager menu, select Performance to view performance metrics. See Also: Gathering routine statistics and reporting can be done by performing the automated maintenance tasks available in Oracle Database 11g. See Oracle Database Performance Tuning Guide 11g Release 1 11.1 for details. 24-12 Oracle Fusion Middleware Administrators Guide for Oracle Identity Manager Repository AWR report, and adjust the instance configuration parameters according to the recommended settings. This is specially required after importing a new connector and completing a round of reconciliation from a new target system so that you can identify the need of any new indexes according to your matching rules. 25 Tuning Application Server Performance 25-1 25 Tuning Application Server Performance This chapter describes how to tune Oracle WebLogic Server for Oracle Identity Manager to improve performance in the following sections: ■ JVM Memory Settings ■ JDBC Connection Pool ■ Number of Message Driven Beans ■ User Interface Threads ■ Disable Reloading of Adapters and Plug-in Configuration ■ Changing the Number of Open File Descriptors for UNIX Optional ■ Tuning the JVM Garbage Collection for Solaris Sparc T3 or T4

25.1 JVM Memory Settings

To change the JVM memory setting: 1. Open the DOMAIN_HOMEbinsetSOADomainEnv.sh or setSOADomainEnv.cmd file. 2. Change the value of DEFAULT_MEM_ARGS and PORT_MEM_ARGS from the default value. 3. Save the setSOADomainEnv.sh or setSOADomainEnv.cmd file. Note: ■ All tuning parameter suggestions and values in this section are for reference purposes only. Values should be modified based on your requirement, application usage patterns, loads, and hardware specifications. ■ Changing any of the settings may require you to restart the server.
