DAE_SHAREDSN

Description:

Checks that in a sysplex environment DAE data set is shared between systems (DAE option SHARE(DSN) is in effect).

This check is only applicable for a system in a Parallel Sysplex® environment. Note, however, that this check is not applicable and will not run on a geographically dispersed Parallel Sysplex (GDPS®) controlling system (K-sys) in a GDPS environment.

Reason for check:

In a Parallel Sysplex environment, if the DAE data set is not being shared, it is possible that the system requests a dump for a problem occurred on another system in the sysplex. To prevent duplicate dumps on all systems in the Sysplex, IBM® recommends that you share the same ADYSETxx parameter values in each system.

This check will detect if the DAE data set is being shared in a Parallel Sysplex environment.

z/OS® releases the check applies to:

z/OS V1R11 and later.

Parameters accepted:

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
