OK, consider this case. All defaults, no TIME= coded anywhere. JES2 parms have TIME=3. Five steps. How long will the job run?

Default job TIME is set in the JOBCLASS definition in the JES2 parameter deck. If JOBCLASS doesn't specify a CPU time limit, the IBM default is 30 minutes.

Also, if your JES2 JOBCLASS has a time lime, then that will control all of it. Found that out the hard way. So if you have a time limit on the JOBCLASS def in JES2, it takes precedent If nothing major in the JOBCLAS def, but you have a STEP TIME coded, then so long as the step time does not exceed the JOBCLASS it will work If you have TIME coded on the JOB and it does not exceed the JOBCLASS, it will work If you have TIME coded on the JOB and the STEP then the JOB TIME limit will restrict the STEPs. If the total time executed for all steps exceeds the TIME= on the JOBCARD then it abends. Good write up on KB here http://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.ieab500 /iea3b5_JOB_and_EXEC_TIME_parameter.htm By coding TIME=1440 or TIME=NOLIMIT, the TIME parameter can instead be used to give a job or step an unlimited amount of time. Specifically, the system allows a step to remain in a continuous wait state for an unlimited time, rather than the time limit established through SMF. However, if TIME=1440 is specified on the JOB statement, any TIME values on an EXEC statement and any default TIME values will be nullified. All steps within the job will have unlimited time, as with TIME=1440 or TIME=NOLIMIT. Note: the JES2 JOBCLASS definition can make things interesting.
