Processing of Primary WTORs

To prevent SA z/OS from replying to primary WTORs as soon as they are received, the replies are not defined directly for the message ID of the primary WTOR. Instead, the issuing of replies to primary WTORs is invoked by other messages or executed commands.

Thus the replies for primary WTORs that are to be deferred are defined for the ID of these invoking messages, or the replies to be issued are provided for a predetermined message ID. For example, the SHUTDOWN automation policy item is used to define the replies to be issued during shutdown.

The reply ID of any stored, primary WTOR to a subsystem can be used for operator communication or the shutdown of this subsystem.

If SA z/OS has to communicate with a subsystem by issuing a reply but an outstanding WTOR has not yet been stored for the subsystem, the RETRY option is used to wait for the required WTOR.

You can define multiple replies with the same pass or selection option for a message ID. These replies can be used in response to a sequence of incoming primary WTORs.
