Using operator commands for application environments

An application environment initially enters the AVAILABLE state when the service policy that contains its definition is activated. AVAILABLE means the application environment is available for use, and servers are allowed to be started for it. There are three options on the VARY command that you can use to change the state of an application environment after it has been made available:

VARY WLM,APPLENV=xxxx,QUIESCE or
VARY WLM,DYNAPPL=xxxx,QUIESCE

The quiesce option causes workload management to request the termination of server address spaces for the application environment upon completion of any active requests. Additional work requests are not handled by the servers, although work requests can continue to be queued, waiting for a server. If you do not want work queued, use subsystem functions to stop the queueing.

You can issue a quiesce action for an application environment that is in the AVAILABLE state. When a quiesce action is issued for an application environment, it first enters the QUIESCING state until all servers have been requested to terminate. It then enters the QUIESCED state.
VARY WLM,APPLENV=xxxx,RESUME or
VARY WLM,DYNAPPL=xxxx,RESUME

The resume option restarts an application environment that was previously quiesced and is in the QUIESCED state. It indicates to workload management that server address spaces can once again be started for this application environment. The new servers process any queued requests and all new requests.

When a resume action is issued for an application environment, it first enters the RESUMING state until all systems in the sysplex have accepted the action. It then enters the AVAILABLE state.
VARY WLM,APPLENV=xxxx,REFRESH or
VARY WLM,DYNAPPL=xxxx,REFRESH

The refresh option requests the termination of existing server address spaces and starts new ones in their place. Existing servers finish their current work requests and end. The new servers process any queued requests and all new requests.

You can issue a refresh action for an application environment that is in the AVAILABLE state. When a refresh action is issued for an application environment, it first enters the REFRESHING state until all servers have been requested to terminate. It then enters the AVAILABLE state.
