Converting the Retention Master File

The RMF can be in one of the following two formats:

Old Format

Uses partially qualified data set names for retention assignment and the new format uses full pattern masking. The samples in this guide show the full pattern masking format.

New Format

Supports all the retention assignment rules of the old format and the full pattern masking described in the CA TLMS Configuration Guide. TRS and real time retention work with either format, but always display the data as it is in the pattern masking format. The new RMF print program in CATRMFP will also work with both RMF formats.

You can continue to use the old RMF utilities (CATRMFU) and the new print program (CATRMFP). However, you must plan to convert to the pattern masking format. The new RMF edit program in procedure CATRMFE will perform the conversion and also initialize a newly allocated RMF, replacing the function of TLMSRMUT.

The conversion process is simple and fast. The RMF is converted in place with no need to re-allocate the RMF.

1. Backup your RMF. This can be accomplished using CATRMFB.
2. Edit the new PROCs CATRMFP and CATRMFE to point to your existing RMF.
3. Run CATRMFP requesting reports TLMS014, TLMS015 and TLMS016.
4. Run CATRMFE with the single command of CONVERT. This converts your RMF.
5. Run CATRMFP again requesting TLMS014, TLMS015, and TLMS016.
6. Use the two reports to verify if your RMF convert is successful.

Note: After conversion, the old procedures will not work with the RMF. CATRMFU will fail.
