How the TPF - CA1 interface works ?
Release : 14.0
Component : CA 1 Tape Management
There is no direct interface from VM - TPF operating system to CA1.
TPF writes to tapes, a job runs and updates the TCDB to take the tape out of scratch status, a second job runs to update the EXPDT out into the future in the TMC, DSN and other information needed.
The synchronization between the ATL/VTS and CA1 will be done via the ROBSCR=YES in the TMOOPTxx of CA1.
