In a JES2 system, you can code a time value in the JES2 format accounting information parameter on the JOB statement or in a TIME parameter on the JES2 /*JOBPARM statement. If the job execution time exceeds this value, JES2 sends a message to the operator.
Examples:
//J3 JOB (,,3)
/*JOBPARM TIME=3 Both of these statements specify that the job cannot use the processor for more than 3 minutes.
