MVS automatic restart management

You can use the MVS automatic restart manager (ARM) to implement a sysplex-wide integrated automatic restart mechanism. A sysplex can use ARM and z/OS® Communications Server persistent sessions spread across many terminal-owning regions (TORs) in a generic resource set.

Automatic restart management (ARM) is a sysplex-wide integrated restart mechanism that performs the following tasks:

Restarts MVS subsystems in place if they abend (or if notified of a stall condition by a monitor program)
Restarts all the elements of a workload (for example, CICS® TORs, application-owning regions (AORs), file-owning regions (FORs), and Db2®) on another MVS image after an MVS failure
Restarts a failed MVS image

ARM and z/OS Communications Server persistent sessions provide good recovery times in the event of a TOR failure, and the TOR restart is reduced because only a fraction of the network must be rebuilt. You can log on to the generic resource while the failed TOR restarts.

ARM provides faster restart by providing surveillance and automatic restart. The need for operator-initiated restarts, or other automatic restart packages, are eliminated.
