CA JCLCheck Runtime Options › Description of Runtime Options › MSS

MSS

The MSS option requests the VTOC of mass storage volumes when necessary to verify the existence of a data set on MSS.

This option has the following format:

Mss|NOMss

Default: NOMss

• CA JCLCheck performs staging after an existence check fails because an MSS volume is not mounted. CA JCLCheck flags this condition with a CAY6067W warning message if you did not specify the MSS option.
• If you have mass storage, use this option to ensure complete validation. Be aware however, that this option can increase the CA JCLCheck running time as well as contribute to contention on the staging volumes. Use this option with caution at peak periods.
