Keeping the operating system catalog entries for tape data sets synchronized with the TMC entries can help eliminate abends and other related problems.
The following CA 1 facilities assist in keeping the operating system catalog entries for tape data sets synchronized with the TMC entries:
This facility automatically uncatalogs scratched data sets from the operating system catalog during scratch processing. Depending on your selection of the CA 1 system option UNCATA, the uncatalog action either one of:
The CA Earl output file generated by TMSCLEAN can be saved and used on other systems with the TMSUNCAT utility to uncatalog tape data sets found on system catalogs. This allows for a single TMSCLEAN to execute in an environment without shared catalogs, and still uncatalog those tape data sets from other systems.
This operating system catalog correspondence utility determines the differences between the TMC and the system catalog. The output report lists the records compared and indicates discrepancies.
Various options are available to limit the comparison. An exit is also available to control the TMC records being processed. Two listing sequences are available, one by data set name (the system catalog controls the comparison), the other by volume serial number (the TMC controls the comparison). The information provided can help you research invalid comparisons and perform the appropriate manual updates to either the TMC or the system catalog.
