A discrete data set profile in the RACF® database contains the volume serial number of the catalog for a RACF-protected VSAM data set. This volume serial number must match the volume serial number supplied on the RACROUTE REQUEST=AUTH macro instruction; otherwise RACF cannot locate the correct profile in the RACF database. (VSAM processing routines supply the volume serial number of the catalog on the RACROUTE REQUEST=AUTH macro instruction.)

The REPRO, RESETCAT, IMPORT, and IMPORTRA commands can cause the volume serial number of the catalog containing a RACF-protected data set to change and differ from the volume serial number in the data set's profile in the RACF database. These commands do not invoke RACF to update the profile in the RACF database. Therefore, the user who is maintaining the RACF-protected data set must update the data set profile with the correct volume serial number.

To update data set profiles, enter the ALTDSD command with the ALTVOL operand. Note that you can use the SEARCH command to build a command procedure containing ALTDSD commands for all VSAM data sets cataloged on the same volume.

Or, to update profiles, you can use the TSO command-procedure facility to:

1. Obtain a list of the catalog entries for a volume for RACF-indicated data sets by using the LISTCAT command.
2. Obtain a list of the RACF-indicated VSAM data sets by using the SEARCH command.
3. Compare the volume serial numbers of RACF-indicated data sets (obtained by the LISTCAT command) with the volume serial numbers of RACF-indicated data sets (obtained by the SEARCH command) to ensure the correctness and completeness of volume serial number information.
