Plan to run TMSXTEND before or after the CA 1® Tape Management System daily maintenance or any other CA 1® Tape Management System batch job. Before you execute TMSXTEND, stop CA 1® Tape Management System batch utilities and shut down the DBS and APEC subtasks of CTS. Disable the CA Vantage™ Storage Resource Management script for CA 1® Tape Management System. The ISPF interface and the old TSOTIQ interface work correctly for individual volume or DSNB inquiries or updates. The range-display in the ISPF interface does not work while TMSXTEND is in progress. For more information about the DBS and APEC subtasks of CTS, see Administrating section.
CA1's script should be disabled during the TMSXTEND. The CA1 script can be: DSKTMCV, DSKTMCF, DSKTMCBTMCDSNB, TMSAUDIT all these scripts can be find in the system script.. or any other user script which involve TMC file.
