Workloads are started initially by scheduling or automation products.
The components of the workload, and the MVS™ images capable of running them, are specified as part of the policies for MVS workload manager and ARM. The MVS images must have access to the databases, logs, and program libraries required for the workload.
Administrative policies provide ARM with the necessary information to perform appropriate restart processing. You can define one or more administrative policies, but can have only one active policy for all MVS images in a sysplex. You can modify administrative policies by using an MVS-supplied utility, and can activate a policy with the MVS SETXCF command.
To use the MVS automatic restart management facility to implement a sysplex-wide integrated automatic restart mechanism, you:
The task of implementing ARM support is part of the overall task of planning for and installing MVS sysplex support. For information about MVS automatic restart management, see OS/390 MVS Setting Up a Sysplex.
Implementing ARM support for CICS generally involves the following steps:

/* Prevent all except GROUP CICSREST restarting */
RESTART_GROUP(DEFAULT)

RESTART_ATTEMPTS(0)
/* Provide ARM support for all CICS regions named in CICSREST */
/* RESTART_ATTEMPTS is default number (3) */
RESTART_GROUP(CICSREST)
