Your folks need to tell you about job classes first - the jobcard CLASS parm.

Ask them for all the details. They should have a one page doc as everyone needs this installation-specific info.

If I don't know an interview question, I either:

1. Make an educated gues, and let them know that's what I'm doing. No one knows everything, and they should be impressed that you can try to reason it out given other knowledge.

2. Tell them I am familiar with the (online?) documentation and use it frequently in such cases.

Hello,

My answer would have been that i do not/will not create jobs that need to run continuously for 3-4 days. . .

In relation to the time parameter Started Tasks are subject to the same rules and restrictions as batch jobs

thx nevilh,
always thought started tasks,
by virtue of being in 'a class of their own',
automatically had different time constraints.

glad to be wiser.

"3-4 days" is a very strange choice, even for an interview.

So what was interviewer's reaction on that?

TIME=1440 exempts the job from all CPU and wait time limit checking the job can execute as long as it needs to. No S322 or S522 abend will occur for the job. TIME=NOLIMIT is the same as coding TIME=1440; no CPU time or wait time limit checking is performed by zOS.

However TIME=MAXIMUM allows the job to use up to 357,912 minutes of CPU time, or about 248.5 days of continuous CPU usage - much more than 3-4 days.
