Example

The POSTSTART commands for the IMS control region can be specified as follows:

Type	AutoFn/*	Command Text
		`MVS &SUBSSUBIDCQSET SHUTDOWN SHAREDQ ON STRUCTURE ALL`
		`MVS &SUBSSUBIDSTA DC`
		`MVS &SUBSSUBIDCHE`

IMS actions can also be defined to be issued as replies to the outstanding WTOR of the IMS control region. This method is only applicable to the DC control region because the DB control region does not allow communication via an outstanding WTOR. Furthermore, issuing a sequence of actions leads to a processing bottleneck. This is because each time it issues a reply, SA z/OS first has to wait for the next outstanding WTOR before it can continue with issuing the next reply. This method is therefore not recommended.
