What are the core functions of CA-1?
CA-1 tracks tape datasets and the physical tapes they reside on. It prevents accidental overwrites of tapes containing valid data by enforcing retention policies. CA-1 also automates tape library management tasks, such as offsite tape rotation.
How do users interact with CA-1?
CA-1 uses control statements entered via JCL (Job Control Language) to perform operations. For example, TMSCLEAN is used to mark tapes as scratch, and TMSCOPY is used to copy the CA-1 database.
Where does CA-1 store its data?
CA-1 uses a database (typically VSAM) to store information about tapes, datasets, and their relationships. Reports are generated using batch jobs that access this database.
How does CA-1 integrate with security systems?
CA-1 can be integrated with other z/OS security products like RACF, ACF2, or Top Secret to control access to tape datasets and CA-1 functions.
