XCF_CDS_MAXSYSTEM
- Description:
- Provide a warning when a function CDS (any CDS other than the
sysplex CDS) is formatted with a MAXSYSTEM value that is less than
the MAXSYSTEM value associated with the primary sysplex CDS.
This is a sysplex-wide check (GLOBAL) , which means that it runs on one system but reports on sysplex-wide values and practices. A global check shows up as disabled for all systems in the sysplex, except for the one where it is actually running.
- Reason for check:
- It is recommended that each couple data set defined to the sysplex
be formatted with a MAXSYSTEM value that is at least equal to the
value defined in the primary sysplex CDS.
If a function CDS has a smaller MAXSYSTEM value, then a system joining the sysplex with a higher slot number will not be able to use the function provided by that function CDS.
- z/OS releases the check applies to:
- z/OS V1R12 and later.
- Parameters accepted:
- None.
- 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.
