Use the VARY WLM,APPLENV=
applenvname, or VARY WLM,DYNAPPL=
applenvname command
to control an application environment. You can perform the following:
- Request that the server address spaces for an application environment
be terminated and start new ones in their place (REFRESH). This is
useful if you have updated resources such as load modules which might
have been cached by the servers.
- Request that the server address spaces for an application environment
be terminated and that any additional work requests be queued but
not selected (QUIESCE or Q).
- Restart the server address spaces for an application environment
that was previously quiesced, or was stopped by workload management
when it detected an error condition (RESUME).
You can use the DISPLAY WLM command to check the status of the
VARY WLM command for the application environments that are affected.
See the “Defining Application Environments” topic in z/OS MVS Planning: Workload Management for
more information on operational considerations for application environments
and the role of the VARY WLM,APPLENV=applenvname, or VARY
WLM,DYNAPPL=applenvname command.
