“Format Utility for Couple Data Sets” describes the IXCL1DSU format utility and the resources that can be defined in a CFRM policy — number of policies, number of coupling facilities within a policy, number of structures within a policy, and number of connections to a coupling facility structure. If the update to an existing policy involves an increase in any of these resources, you must format a new couple data set.

When formatting the couple data sets to support CFRM policy data, ensure that the value specified for MAXSYSTEM matches the value that was specified for MAXSYSTEM when the sysplex couple data sets were formatted.
