Master catalog volume

z/OS Planning for Installation
GA32-0890-02

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.
