About Real-time Processing

CA 1 Real-time Processing includes the following features which enhance the tape processing facilities of the operating system:

The Scratch Pool Management feature allows you to restrict nonspecific output access to tape pools of CA 1 controlled volumes and also allows the option of enabling real-time stacking.
The Specific Mount Message option provides for message prefixing of specific output requests to indicate tape volume status in the TMC.
CA 1 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 keeps the CA 1 database updated with the current OS catalog status for each CA 1 controlled tape file.
