Why and when to perform this task
If you have an application that is critical for your business, you need facilities to manage failures. z/OS provides rich automation interfaces, such as automatic restart management, that you can use to detect and recover from failures. Automatic restart management handles the restarting of servers when failures occur.
WebSphere Application Server for z/OS uses the z/OS Automatic Restart Management (ARM) to recover Application Servers. Each Application Server running on a z/OS system (including servers you create for your business applications) are automatically registered with an ARM group. Each registration uses a special element type called SYSCB, which ARM treats as restart level 3, assuring that RRS restarts before any Application Server.
