Details

1. Edit opmn.xml and add -XX:PermSize=256M and -XX:MaxPermSize=512M in the OC4J_SOA container. From the Sun documentation, a description of this value is as follows: -XX:MaxPermSize: Size of the Permanent Generation. [5.0 and newer: 64 bit VMs are scaled 30% larger; 1.4 amd64: 96m; 1.3.1 -client: 32m.]

Applicable Versions

Oracle SOA Suite 10g (10.1.3)
