SMS_CDS_REUSE

Description:

This check verifies that the active control data set (ACDS) and communications data set (COMMDS) are defined with the REUSE option.

Reason for check:

As a best practice, defining ACDS or COMMDS with the REUSE option helps to avoid running into space problems (SMS reason code 6068) as result of subsequent ACDS or COMMDS updates, or IMPORT/EXPORT functions.

z/OS® releases the check applies to:

z/OS V1R12 and later.

User override of IBM® values:

The following shows the default keywords for the check, which you can override on either a POLICY statement in the HZSPRMxx parmlib member or on a MODIFY command. This statement may be copied and modified to override the check defaults:
