About Scratch Pooling

CA TLMS Scratch Pooling includes several features which enhance the tape processing facilities of the operating system. These include:

The Scratch Pool Management feature allows you to restrict nonspecific output access to tape pools of CA TLMS controlled volumes.
The Specific Mount Message option provides for message prefixing of specific output requests to indicate tape volume status in the VMF.
CA TLMS may not allow the use of a tape volume for input or output for various reasons.
NL and BLP processing requires additional processing including the request for the volume serial number.
Nonresident tape volume processing may require additional information from the operator.
Catalog Interface to keep the CA TLMS database updated with the current OS catalog status for each CA TLMS controlled tape file.
The Real-time Stacking feature allows you to define scratch pools that support the stacking of multiple files on each volume in the pool without requiring application JCL changes.

CA TLMS console messages are detailed in the Message Reference Guide.
