FORCE is not a substitute for CANCEL. Unless you first issue
CANCEL for a cancelable job, the system issues error message IEE838I.
The steps to use in the process are:
Issue the CANCEL nnn command,
making several attempts if necessary.
Use the DUMP command if you want a dump produced. Respond to the
prompt for parameters with the job name or ASID of the "stuck" job,
as well as ASID(1)=MASTER.
Issue the FORCE nnn,ARM command
for non-cancelable procedures.
Issue the FORCE nnn command
only when the previous steps fail.
Attention: Never use the FORCE command without first understanding
that:
After issuing FORCE, you might have to re-IPL.
If you issue FORCE for a job in execution or for a timesharing
user, the system deletes the affected address space and severely limits
recovery unless you use the ARM parameter. (The ARM parameter is described
in Parameters.)
If you need a dump, you must issue the DUMP command before
you issue the FORCE command. Once you have issued a FORCE command,
it is usually not possible to get a dump of the failing address
space.
If your system was part of a global resource serialization ring
(GRS=START, GRS=JOIN, or GRS=TRYJOIN was specified at IPL) but has
been quiesced (by entering the VARY GRS(system name),QUIESCE
command), FORCE processing might not complete immediately. The system
suspends termination of all address spaces holding global resources
until the quiesced system rejoins the ring or is purged from the ring.
Use a DISPLAY GRS command to determine GRS status.
The availability manager (AVM) cannot be ended by
a STOP or CANCEL command. To end AVM, a FORCE AVM,ARM command
is required.
When you use the FORCE command to end the availability manager
(AVM) address space, the operator must restart that address space
by issuing the START AVM,SUB=MSTR command.
You can enter FORCE only from a console with master authority.
