CATVMFX runs in three modes to perform different functions, EXTEND, TEST, and RESET. To verify the shared VMF environment before you perform a switch, run CATVMFX in TEST mode. The utility is designed to test as many environmental details as possible before proceeding with a VMF switch, reducing the likelihood of a problem.
Select a mode by specifying one of the following values for the ‘DO=’ parameter in the CATVMFX PROC.
Instructs CATVMFX to initiate the dynamic VMF EXTEND process and terminate once all TLMSs have switched VMFs. This process performs the actual EXTEND, and all TLMSs use the new VMF when completed.
Instructs CATVMFX to initiate the dynamic VMF EXTEND process, but skips the switch and recatalog steps. This process only tests the EXTEND process, and all TLMSs continue using the old VMF when completed.
Instructs CATVMFX to clean up the VMF control record. This process clears all residual data that is left behind from an aborted EXTEND/TEST. (CATVMFX uses the VMF control record to issue commands to all TLMSs). Due to the nature and impact of this utility, contact CA Support for any error conditions that occur.
Note: The CATVMFX EXTEND process does not perform any VMF reorganization functions. Perform the VMF reorganizations to remove orphan chains, clear the reuse chain, reorganize AUX records, and reassign chain-ids.
We recommend that you run the batch version of VMF Extend copy (HLQ.CTAPJCL(TLMJVMW3)) before running an EXTEND. This version validates that all records in the old VMF can be copied to the new VMF. CATVMFX stops after the first record in error, but the batch version logs all the errors in CAIMSG.
