SMS_CDS_REUSE_OPTION

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 sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change
