16h Validate and activate the SMS configuration.

You must perform this step at initial installation. During migration, you might optionally perform this step if you have made changes in the SMS definitions and programs used by OAM.

You cannot use OAM until a configuration containing all the elements described in this topic have been defined and activated.

Only one SCDS can be activated at any time. Activating another SCDS or reactivating the current SCDS while OAM is running might cause OAM to restart. How soon OAM is notified of the SCDS activation depends on the time interval specified with the INTERVAL keyword in the IGDSMSxx PARMLIB member. OAM restarts if RESTART=YES is specified on the OAM procedure JCL parameter. During this reinitialization, all libraries and drives are set to either online or offline according to the attributes defined in the SCDS that caused OAM to restart. After the restart completes, all libraries and drives should be displayed and set to the desired operational status.

See z/OS DFSMSdfp Storage Administration for information about validating and activating the configuration that you have just defined.
