Master catalog volume
The recommended types of data sets for this cluster-related volume
are:
- Master catalog
- BRODCAST
- Customer parmlib concatenation (not the SMP/E DDDEFed PARMLIB)
- Customer proclib concatenation (not the SMP/E DDDEFed PROCLIB)
- UADS (if used)
- VTAMLST
- SMS ACDS, CDS, model DSCB, HSM, RMM, and so forth
- APPC VSAM data sets (side information, TP profile)
- System control files (TCP/IP configurations and so forth)
- Primary RACF® database
- IODF
- SYS0.IPLPARM
- UCATs
- SYS1.DDIR sysplex dump directory data set
- DAE data set
Considerations when setting up the master catalog volume are:
- BRODCAST (when individual user BRODCAST data sets are in use), LOGREC, parmlib, proclib, UADS, IODF, and DAE are low-activity data sets.
- Customer parmlib and customer proclib should be concatenated with other parmlibs and proclibs. For information on using system symbolics in concatenated parmlibs, see z/OS MVS Initialization and Tuning Reference.
