For years TLMSVCVS was the main source for finding volume chaining errors within the VMF.
With the CA TLMS 12.6 release, TLMSVMFV will replace TLMSVCVS. The major updates are:
- Report on dataset chaining errors. TLMSVCVS only reported on volume chaining errors.
- Ability to delay the reporting of open volumes.
- Multiple levels of detail reporting.
- Report on orphaned records.
- Summary of VMF usage.
TLMSVMFV is executed to verify the VMF using the same technique used by TLMSVMFU for the VMF utilities. The technique allows TLMSVMFV to verify VMF record chaining without "running the chains". This prevents I/O errors from bad chains and allows TLMSVMFV to continue verification of a chain after an error is detected. TLMSVMFV also finds orphaned records. Orphaned records are records which cannot be found by TLMS batch processing that starts with the beginning of a tape chain.
We recommend running with a LEVEL of 5 and a DELAY of the number of days that your longest tape job will execute.
The scope of the verification and reporting is controlled by the following CATVMFV parameters:
DELAY
This parameter instructs TLMSVMFV to delay the verification of tape chains for the specified number of days. This prevents reporting of false errors for tapes which are being created while CATVMFV is running.
Specifies the number of days TLMSVMFV waits after the creation date before any given verification.
Range: 0 to 9999999 days
LEVEL
This parameter specifies the level of detail TLMSVMFV is to report. The LEVEL parameter can greatly reduce the size of the TLMS064 report. By default TLMSVMFV uses DELAY=3 and LEVEL=1. The report levels are:
- Level 1 is the default report level.
- Level 5 and above print orphans records. These are records which are not connected to valid TLMS chains. These records are lost during a VMF RESTORE.
- Level 9 is the most detailed report. Level 9 overrides the DELAY PARM. Level 9 can only be run against a VMF that has no activity.
Specifies the level of detail for verification and reporting. The lower the value of LEVEL the less detail produced.
Valid values: 1, 2, 5, and 9
PRM keywords can be specified in any order and are separated by commas or blanks.
Modify the CATVMFV parameter for SORT to values similar to those in CATVMFU. These vary with the size of the VMF, for example:
SORTLIB='SYS1.SORTLIB'
SPCVMF='(CYL,(5,5))'
WORK='SYSALLDA'
Specify the DELAY and LEVEL parameters via CATVMFV PRM=. For example:
CATVMFV PRM=’DELAY=6 LEVEL=5’
