The purpose of deadline scheduling is to help JES3 use available resources best. For example, if you work first shift and submit a job at the end of the day, you do not need output until the next morning. Specify 7 a.m. of the next day in the DEADLINE parameter and assign the job a low priority. JES3 can schedule the job any time during the night when the resources are available. But, if the job has not been scheduled by several hours before 7 a.m., JES3 increases its priority. JES3 will increase the job's priority periodically until it is selected for execution by 7 a.m.
Examples:
To execute a job by 7 a.m. on January 20, 1986, code:
//*MAIN DEADLINE=(0700,B,012086)
To execute a job by 7 a.m. on January 20, 2000, code:
//*MAIN DEADLINE=(0700,B,01/20/2000)
