This section tells you how to:
- Stop management of a CICS® system
- Restart management of a CICS system
- Terminate a CICS system.
To stop the MAS agent code in an active CICS system, either:
- Issue the STOP action command from the MAS view, or
- Run transaction COSH in the MAS. COSH can be started at a 3270
terminal, at a console, or via ATI.
Stopping the MAS agent prevents CICSPlex® SM
from accessing the MAS until either the CICS system
is restarted (see topic Preparing to start an MVS MAS)
or the COLM or CORM transaction is issued (see Restarting management of a CICS system).
Note:
When a MAS is active as a CICSPlex SM workload management routing region,
and the dynamic routing program is set to EYU9XLOP, the STOP command
is not honored. In this situation, before you issue the STOP command
you must use the CICSRGND view to change the dynamic routing program
from EYU9XLOP to the CICS default dynamic routing program,
DFHDYP, or another valid dynamic routing program.
To reactivate a running CICS system as a MAS, issue the CICS transaction:
- COLM
- For a local MAS
Note:
If you want a local MAS to be recognized as a workload management routing region
when CICSPlex SM resumes managing the system, make
sure the dynamic routing program is set to EYU9XLOP. To change the
dynamic routing program, use the CICS CEMT
transaction before you reactivate the local MAS.
To verify that the CICSPlex SM MAS shutdown processing
is properly installed, you can terminate the CICS system
and check the log for the following shutdown message:
EYUXL0016I MAS shutdown complete
To terminate a CICS system running the MAS agent
code, use the CICSRGN view to issue the desired shutdown command.
For more information about the CICSRGN view, see the CICSPlex System Manager Operations Views Reference manual.
