Stopping the z/OS PAS
BMC recommends the following actions for CMF MONITOR to adjust for Daylight Saving Time changes:
For Spring Daylight Saving Time, stop the z/OS PAS prior to the time change and start the PAS again after the time change.
For Autumn Daylight Saving Time, stop the z/OS PAS prior to the time change and wait one hour before restarting.
Although these changes are meant specifically to accommodate CMF MONITOR SMF records (which use local time), be aware that stopping the PAS affects not only CMF MONITOR but also other products that are running in the PAS, such as MainView for z/OS, MainView for UNIX System Services, or MainView SYSPROG Services.
By using the CONtext command to display the DIAGSESS view in PLEXMGR, you can see the active sessions on the system that you are viewing.
To stop the z/OS PAS
- Verify the procedure name for the z/OS PAS that you want to stop.
- From the system operator console, enter the STOP command:
Or, if the PAS was started with an ID, enter
BMC recommends using the STOP command rather than the CANCEL command to stop the z/OS PAS. z/OS PAS started task parameters discusses these two parameters.
Optionally, you can stop the z/OS PAS data collectors only and leave just the Extractor operating to conserve system resources; for example, when you are not using CMF MONITOR Online. When you stop the data collectors, any local or cross-system sessions with CMF MONITOR Online or MainView for z/OS are disrupted, but the Extractor is not.
To enable and disable the z/OS PAS data collectors without affecting the Extractor, see information about the DC parameter in Controlling z/OS PAS operation.
