ARM is a recovery function that can improve the availability of specific batch jobs or started tasks. When a job or task fails, or the system on which it is running fails, automatic restart management can restart the job or task without operator intervention. If a job or task fails, automatic restart management restarts it on the same system it was running on at the time of the failure. If a system fails, automatic restart management restarts the work on other systems in the sysplex configuration; this is called a cross-system restart. IBM recommends the use of ARM, with modifications to automation, as required for coordination of ARM and automation restarts. However, because ARM may interact with customer automation routines, it is optional.
