IGGCATxx (DFSMS catalog configuration)

IGGCATxx allows you to define catalog system parameters and make permanent changes between IPLs. You can specify other catalog parameters in the LOADxx member of SYS1.PARMLIB and the SYSCATxx member of SYS1.NUCLEUS. The IGGCATxx parameters are processed both at IPL and when CAS is restarted. See The Intersection of SYSCATxx, LOADxx, IGGCATxx, and MODIFY CATALOG Command in z/OS DFSMS Managing Catalogs.

Use the command DISPLAY IPLINFO,CATALOG to display the catalog system parameter members currently in effect at a given time.
