The set id. number is a number that is used to identify a job set. All members of a job set are assigned the same job set number during processing. The job set number can be left off and the system will automatically assign one. Alternately a number can be explicitly provided when the first job of the set is initiated. The automatically assigned numbers are always in the range 1 to 99,999. Thus it is best to only assign manually numbers greater than this.
The set number is needed if a failed job must be rerun manually to allow a job set to complete its processing. For example to start up a job to just run by itself and use a given set id., use the following command.
C:\> schedule submit job1/set_id=23
