The default value for implicitly defined VVDSes can now be specified in the IGGCATxx member of PARMLIB, which is relatively new (z/OS v1.13):
VVDSSPACE(primary,secondary) Specifies the number of tracks for primary and secondary allocations that the Catalog Address Space (CAS) should use for an implicitly defined VVDS. The specified values are preserved across a CAS restart and are applied at IPL. If a zero secondary value is specified on a VVDSPSACE(pri,sec) parameter and the primary value is valid, then on an IPL, a default of 10 tracks will be substituted for the secondary. On a restart of the Catalog Address Space the value that existed prior to the CAS restart is retained. The default is VVDSSPACE(10,10). regards, Joe D'Alessandro ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
