A CICS® Resource that provides information about the pool of JVMs in the CICS address space. This resource is not supported inCICS TS for z/OS®, Version 5.1 and later versions.

The following actions are supported:
SET
Set a CICS system attribute according to the new value you specify in an overtype field.
DISABLE
Set the pool status to disabled.
ENABLE
Set the pool status to enabled.
FORCE
Terminate all tasks using JVMs in the pool by the CICS SET TASK FORCEPURGE mechanism.
PHASEOUT
Mark JVMs for deletion.
PURGE
Terminate all tasks using JVMs in the pool by the CICS SET TASK PURGE mechanism.
START
Start one or more JVMs using the specified JVM profile and execution key.
