Suspending a Resource

A resource is suspended using the INGSUSPD command. This command accepts resource types APL, APG, MTR, and REF. Like requests to start or stop the resource, INGSUSPD produces a request called suspend request.

Using INGVOTE, suspend requests can be viewed, canceled, and killed. The latter two actions refer to resuming the resource.

A suspend request is handled by the automation manager but processed asynchronously by the automation agent. It succeeds, if there is no startup or shutdown currently in progress for a given resource. If there is a startup or shutdown in progress, the suspend request is still recognized but is pending; it will be honored only once the desired status is reached.

Similar to INGREQ for start or stop requests, SA z/OS allows you to specify a SCOPE parameter of the INGSUSPD command to suspend just a single resource or all resources in the dependency chain as illustrated in Figure 1. For a SCOPE=ALL request, suspend votes are propagated along the dependency chain to all dependents.

The SCOPE parameter can be a powerful way to suspend a whole tree of resources at once. For the effect of this parameter when used for groups, see also Suspending APGs or Its Members.
