Specifying a default JVM for Java dump analysis

Performing Java™ dump analysis requires a JVM that has a service level equal to, or greater than, the JVM that recorded the Java dump. Optional DD statements can specify default JVMs to use when the version of Java indicated by the dump JAVA_HOME path cannot be found on the system.

You can specify default JVMs by adding the HFZJVM and HFZJVM6 DD statements to the HFZS subsystem JCL for Java.
  • The HFZJVM DD statement specifies the path to a default 31-bit JVM.
  • The HFZJVM6 DD statement specifies the path to a default 64-bit JVM.
//HFZJVM   DD   PATH='path'
//HFZJVM6  DD   PATH='path'
