Utilities › TMSSPLIT Utility—Select Data from the TMC for Use by TMSMERGE › Split Procedure

Split Procedure

Step 1

Execute TMSPTRS and correct any reported multivolume or multi-data set chaining errors. TMSPTRS must run with a condition code of 0 before you continue to the next step.

Step 2

Create a list of volume serial numbers for TMSSPLIT. CA Earl is an excellent utility for creating this list. It provides the capability, for example, to select only those volumes that are not in scratch status and reflect data set names beginning with the characters XYZ, effectively automating the process of deciding which tapes should move.

The list can be created through other means, in any sequential format, as long as the VOLSERS field is in the same offset of each record and is identified to TMSSPLIT with control statements.

Step 3

Stop tape processing and CA 1 batch/online functions on all CPUs sharing the TMC.

Step 4

Execute TMSCOPY to back up the TMC and reset the Audit data set pointers.

Step 5

Execute TMSSPLIT. The output of TMSSPLIT provides information on the number of DSNB and Audit records that is required at the receiving site and a list of every volume selected for the split. This output should be carried to the receiving site along with the export tape. It is recommended that a backup of the export data set be created with IEBGENER or a similar utility.

Step 6

If it becomes necessary to restore the TMC, execute the TMSCOPY utility with PARM='RESTORE,NOAUDIT', using the backup created in Step 4, and return to Step 1. If the ACTION control statement was omitted, no restore operation is needed.
