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 IDIJVM, IDIJVM6, and IDIJVM11 DD statements to the IDIS subsystem JCL for Java™.
- The IDIJVM DD statement specifies the path to a default 31-bit JVM.
- The IDIJVM6 DD statement specifies the path to a default 64-bit JVM for Java 10 or earlier versions.
- The IDIJVM11 DD statement specifies the path to a default 64-bit JVM for Java 11 or later versions.
//IDIJVM DD PATH='path'
//IDIJVM6 DD PATH='path'
//IDIJVM11 DD PATH='path'
Note: The Diagnostic Tool Framework for Java (DTFJ) has internal changes after Java 8. IDIJVM11 is a required DDname
if co-existing with Java 8 64-bit applications.
