Automatic Restart Management Rules

An Automatic Restart Management (ARM) rule triggers when the Automatic Restart Manager component of z/OS attempts to restart an ARM-registered job or started task after an unexpected termination.

The restart may occur on the same system or on another system in the sysplex if the termination was due to a complete system failure.

ARM rules provide the ability to:

• Intercept ARM restart events before the restart occurs.
• Override JCL or start text by setting the modifiable ARM event variables or by terminating the restart event.

If System State Manager is being used to manage resources that are using ARM for restart, ARM rules provide the ability to either:

• Suppress the ARM restart if System State Manager has already acted to restart the resource.
• Allow ARM to proceed and prevent System State Manager from duplicating the restart action.
