Overview

MVS™ automatic restart management is a sysplex-wide integrated automatic restart mechanism that:

Note:
CICS reconnects to DBCTL and VTAM® automatically if either of these subsystems restart after a failure, and to DB2 if you specify AUTO on the STRTWT parameter in the resource control table (RCT). There is no dependency on the MVS automatic restart manager for this reconnection support, which is provided automatically on any CICS region.

You cannot use MVS automatic restart for CICS regions running with XRF--it is available only to non-XRF CICS regions. If you specify XRF=YES, CICS de-registers from ARM and continues initialization with XRF support.

MVS automatic restart management is available only to those MVS subsystems that register with ARM. CICS regions register with ARM automatically as part of CICS system initialization. If a CICS region fails before it has registered for the first time with ARM, it will not be restarted. After a CICS region has registered, it is restarted by ARM according to a predefined policy for the workload.
