Using MVS automatic restart management for faster restart

Automatic restart management (ARM) is a sysplex-wide integrated restart mechanism that:

You can use the MVS automatic restart manager to implement a sysplex-wide integrated automatic restart mechanism. A sysplex can use ARM and VTAM® persistent sessions spread across many TORs in a generic resource set. ARM and VTAM 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 has to 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. For more information about MVS automatic restart management, see the CICS Transaction Server for z/OS® Installation Guide, and the z/OS MVS Setting up a Sysplex manual, SA22-7625.

MVS automatic restart is available only to non-XRF CICS regions.
