To capture the current Java™ state from a Java program, Fault Analyzer can be invoked to create a history file fault entry, along with an associated MVS™ SVC dump.
Fault Analyzer Java wrapper utility wraps a callable Java application in a try-catch block by using the FA Java class.
Fault Analyzer provides a JVMTI (JVM Tool Interface) agent. The agent runs inside a Java™ Virtual Machine (JVM) and can inspect the state of the running Java application.
When the JCLcapture option is in effect during real-time processing, Fault Analyzer attempts to obtain the JCL and save it in the fault entry. This feature is available with JES2 only.
The following describes the entry and return specifications for IDISNAP.
