When a volume is scratched, TMSCLEAN has the ability to remove the associated data set(s) entry from the system catalog using operating system catalog macros.
The UNCATA parameter in the system options member, TMOOPTxx in hlq.CTAPOPTN, specifies which data sets TMSCLEAN can uncatalog. A value of YES for this option allows TMSCLEAN to uncatalog all data sets. If the value is set to GDG, GDG data sets and data sets expired from Cycle Control or Catalog Control are excluded. A value of NO prevents any uncatalog operations when a tape is scratched by CA 1.
Note: For more information about CA 1 system options and instructions for changing the options, see the Programming Guide.
Another aspect in keeping the TMC and system catalog synchronized involves TMSCLEAN scratch processing. The report file produced by TMSCLEAN can be used as input to the TMSUNCAT utility on other systems in an environment that does not share catalogs. The report file helps synchronize the system catalogs on all CPUs while executing TMSCLEAN on one CPU.
