CA MIA enables z/OS sites, z/VM sites, and mixed z/OS and z/VM sites with CMS users and z/OS guests, to share tape devices automatically and safely. CA MIA provides integrity for data that resides on tape and eliminates the necessity for manual commands that are typically associated with tape device sharing.
CA MIA consists of the following facilities:
Prevents jobs on different systems from simultaneously allocating the same tape, and prevents jobs from allocating devices already in use on another system.
Improves device processing by permitting tape device allocation requests by model and influencing device selection.
