Use the Real-time Catalog Interface to automatically keep your TMC record in sync with the z/OS Catalogs and eliminate having to run the TMSCTLG batch utility on a daily basis.
Business Value:
With the Real-time Catalog Interface, CA 1 updates the TMC as you catalog or uncatalog tape data sets. This feature helps ensure that the CA 1 TMC and system catalogs are properly synchronized and allows you to reduce the number of CA 1 daily maintenance jobs.
Additional Considerations:
When you set the option OCTLG (found in the TMOOPTxx member of the CTAPOPTN library) to NO, you can stop running the catalog maintenance program TMSCTLG, removing two steps of your daily job for CA 1.
Using this option, TMSCLEAN program processes the tapes under CATALOG control by checking the tape catalog to help ensure that the tape is not cataloged before CA 1 expires, and scratches the tape. TMSCLEAN does the processing that TMSCTLG used to do. This feature eliminates two programs from the CA 1 daily job stream and also eliminates the time spent by TMSCTLG to locate the ICF catalogs for every data set under CATALOG control. If you have unshared ICF catalogs, this feature eliminates the need to do IDCAMS LISTCAT for every catalog, which is used as input to TMSCTLG.
A CA 1 Health Check has been created to raise an exception, when it discovers the OCTLG option is set to YES.
Note: For more information about the OCTLG option, see the System Programmer Guide. For more information about the programs TMSOSCAT and TMSCLEAN, see the Utilities and Reports Reference Guide. For more information about CA 1 health checks, see the Administration Guide.
