Guidelines for changing the automatic restart management policies

Because server instances register with the default restart group, automatic restart management attempts to restart the entire default group on another system in the sysplex when a system failure occurs. To create a restart group other than this default group, you need to follow certain rules.

If you want to create a restart group other than this default group, you need to comply with the following rules and restrictions that apply for z/OS® automatic restart management policies. For more information about how to actually change these policies, see, z/OS MVS™ Setting Up a Sysplex (SA22-7625). Either set up the location service daemon and node agent for restart-in-place or remove them from your ARM policy. Since WebSphere® Application Server must be running on all systems that might be used to perform recovery, the application servers will use the location service daemon and node agent that are already running on the alternate system. If the location service daemon attempts to restart on the alternate system, it will fail. If the node agent restarts on the alternate system, it will have no recovery work to do.
