Workload Automation Restart Options for z/OS Schedulers uses a default subsystem name. If needed, the default subsystem can be overridden by use of U11SSSEX user exit or by using override DD.
By default, CA 11 always use the CAL7 subsystem. To use a different subsystem other than the default subsystem, you can either code the U11SSSEX exit or use the a DD dummy override. U11SSSEX can be set up so that subsystem selection is based on jobname, or other criteria such as job class, accounting fields, or userids. Prior to r11.0, only the U11SSSEX could be used whereby the CA 11 Tracking System was invoked. With r11.0 both the exit and override DD will invoke the CA 11 Tracking System so that if a jobs abends it is set for restart.
The ddname for the override is specified as follows:
Where xxxx is specifies the subsystem name of the CA 11 release that is to be selected. The override DD can appear anywhere in the JCL of the U11RMS step as a //@SSNxxxx DD DUMMY statement. The override DD can also be used in utilities and reports such as U11MGR, U11RCP, U11OBD etc.
User exit U11SSSEX can be set up so that subsystem selection is based on jobname, or other criteria like job class, accounting fields, or userids. A sample of this exit can be found in the CAL7OPTN (PPOPTION prior to r11.0) library.
