Dumping diagnostic information
Dumps contain diagnostic information that can be used when investigating system problems. Various options are available when obtaining dumps.
Dump options are available for use with the MVS™ system command
If the IBM® JVM is used, a subset of the options can be used to provide JVM dumps. The IBM JVM can produce a Java™ heap dump, a Java dump, or a Java system dump. These are produced by a running JVM, and can be requested during typical operation of the CICS® Transaction Gateway. The dumps contain diagnostic information that can be used when investigating system problems.
For further information on IBM JVM dumps, see the IBM Java Diagnostic Guide at IBM Java Diagnostic Guide.
