SET_STORCLAS

The SET_STORCLAS keyword specifies an SMS storage class to be assigned to an SMS data set.

Syntax

Read syntax diagramSkip visual syntax diagramSET_STORCLAS=storclas$NULL

SET_STORCLAS=storclas|$NULL

Where:

storclas is the 1 - 8 character string that specifies the SMS storage class. Wildcard characters are not permitted.

Notes:
  1. If you remove the storage class, you effectively make the data set non SMS-managed. To remove the storage class that is assigned to a data set by an SMS ACS routine, specify SET_STORCLAS=$NULL.
  2. If you add a storage class to a data set that originally did not have one assigned to it, it causes the data set to become SMS-managed.
  3. SET_STORCLAS requires additional calls to SMS Configuration Services and its presence in the RULEDEFS member can cause a measurable increase in CPU time for all of the tasks in the system, especially tasks that perform many allocations. Therefore, carefully consider the specification of SET_STORCLAS in your rule definitions member.

Default

None.
