Java Virtual Machine Configuration

The IBM Cúram Social Program Management application requires additional parameters to be passed to the JVM running the Application Server. Set the following system environment variables:

• USER_MEM_ARGS : This should be set to a value relevant to your application e.g.-Xmx712m. This environment variable is set by the app_runtimewls.xml script using these properties, which can be defaulted as follows or set in the AppServer.properties properties file:

  Table 1. Memory Arguments

  Property Name	Default Value	Description
  curam.server.jvm.heap.size	1024	Specifies the JVM heap initial and maximum sizes.
  curam.server.jvm.permgen.size	-XX:PermSize=128m -XX:MaxPermSize=256m	Specifies the initial and maximum PermGen sizes.

  If you override the USER_MEM_ARGS environment variable directly you must also provide values for the JVM PermGen space as shown in Table 1.

• WLS_REDIRECT_LOG : Output file e.g.<WebLogic Server Install directory>/<domain_repository>/<DomainName>/logs/<server.name>_Redirect.log
• JAVA_OPTIONS : This environment variable is used for two purposes.
  1. This environment variable should be used to set the headless mode. The headless mode property is only required for UNIX and it should have a value of-Djava.awt.headless=true
  2. This can be used to pass additional parameters to the WebLogic Server JVM when starting the Application Server.
