25-2 Oracle Fusion Middleware Administrators Guide for Oracle Identity Manager

25.2 JDBC Connection Pool

Oracle Identity Manager uses the oimOperationsDB and oimJMSStoreDS datasources deployed on Oracle WebLogic Server. By default, maximum connections is set at 50. You may have to increase this based on the requirement. To increase the capacity of the JDBC connection pools: 1. Open the WebLogic Server Administration Console. 2. For JDBC Datasource xlXADS:

a. Click Services, JDBC, Data Sources, oimOperationsDB, and then click the

Connection Pool tab. b. Adjust the Initial Capacity and Maximum Capacity based on requirement. For JDBC Datasource xlDS:

a. Click Services, JDBC, Data Sources, oimJMSStoreDS, and then click the

Connection Pool tab. b. Adjust the Initial Capacity and Maximum Capacity based on requirement. 3. Save and activate the changes.

25.3 Number of Message Driven Beans

Oracle Identity Manager uses Message Driven Beans MDBs for processing all offline activities, such as reconciliation, auditing, requests, attestation, and for its internal kernel operations. By default, total of 80 MDB instances concurrently serve requests. However, based on the requirement, this can be increased by modifying the OIMMDBWorkManager configuration. To do so: 1. Login to WebLogic Administrative Console.

2. Navigate to Environment, Work Managers, and then to

MaxThreadsConstraint-1 . 3. Change the count from 80 to a higher number per your requirement.

25.4 User Interface Threads

By default, Oracle Identity Manager provides 20 front-end thread configurations. These threads are used for serving front-end requests. To change the number of front-end thread configurations: 1. Login to WebLogic Administrative Console. Note: Add the following option to prevent StringIndexOutOfBoundsException error: -XX:-UseSSE42Intrinsics This parameter is required only for Sun JDK. Note: Ensure that any increase in number of connections on the application server connection pools are compensated by database configuration changes. You might have to increase the MAX SESSIONS settings on Oracle Database.
