What it is procedure to split the TMC file which is shared between several partitions, to get own one TMC file per partition ?
Once the n systems are isolated to seperate ranges we can then use TMSGRW to get a list of the volsers for each system. Use this as input to TMSSPLIT
to get the information from the TMC. The output from TMSSPLIT will be used as input to TMSMERGE.
The TMSSPLIT and TMSMERGE can be found on the Utilities and Reports Guide.

Review the following considerations before beginning the Split procedure.
The receiving site should take the following into consideration:
If the sending or receiving site uses the Scratch Pool Management feature, the hlq.CTAPOPTN members defining the tape pool options need to be built/integrated. Console operators and users should be informed of any visible changes this may cause. The same holds true for the CA 1 options defined in the TMOOPTxx and TMOEDMxx members of hlq.CTAPOPTN. The Retention Data Set used by TMSEXPDT, and the PDS used by TMSPULL, will require similar accommodation if either data set is in use at either location.
Note: When using PARM=DEFAULT with TMSMERGE, the FLAG1 =x’01’ ('eligible for RDS override') bit will be turned on in ALL the new merged TMC records. If there is a matching RDS entry, this allows that the EXPDT of the tape is overridden. To ensure that the proper expiration date is assigned to your datasets: review your RDS entries or incorporate your sending RDS entries into the receiving site’s Retention Dataset (RDS) before running TMSEXPDT. Otherwise, premature retention expiration may occur.
