Deactivating service items
You can back off a set of dynamically activated service items, if you need to. This might be necessary if, for example, a problem is encountered with a dynamically activated service item or if a particular service item is no longer necessary.
To deactivate the service items, issue:
F OMVS,DEACTIVATE=SERVICEOnly the service items that were activated when F OMVS,ACTIVATE=SERVICE was
last issued are backed off. You will see a list of service items to
be deactivated and you will be asked whether the deactivation should
proceed.
