Determining if VSAM batch logging is enabled

You can determine if CICS® VR VSAM batch logging is enabled for a VSAM sphere by examining the contents of the FRLOG parameter in the catalog entry of the VSAM base cluster. You can run the LISTCAT ALL program against a VSAM base cluster to view the contents of the FRLOG parameter, along with many other parameters.

To view the FRLOG value defined for a data class, you can display the attributes of the data class using the ISMF "DATA CLASS LIST" panel:

The value in the FRLOG column indicates if CICS VR VSAM batch logging is enabled for the listed data classes. A blank value indicates an FRLOG setting of NULL.
