An element representing a job or started task can be restarted with persistent restart text. Persistent restart text is the JCL or started task command that was used to originally start the job or started task. An element representing an abstract resource cannot be restarted with persistent restart text because automatic restart management has no knowledge of how the element was started; no persistent restart text is available. To restart a failed element that represents an abstract resource, automatic restart management must be supplied with restart text. Restart command text can be supplied in the following ways:

• By the application when it registers on the IXCARM macro with the STARTTXT keyword
• In the RESTART_METHOD statement in the ARM policy
• By the element restart installation exit in the ERESTARTTXT or EREJCLDATASET fields.
