Mainframe, MVS and zOS Discussion

Can anyone please tell me the difference between Successor Job and Trigger Job, as both type of Jobs wait for its predecessor? Is there any benefit of one on another?

The difference only appears when dealing with multiple job streams. Example: job A triggers job B triggers job C. At the same time, there is a different job stream where job D triggers job E triggers job F. Job B has a successor job of job F. If job E gets done at 11 AM and job B runs until 12 noon, job F will not start until job B completes. Job E triggering job F is a necessary condition to allow job F to execute, but it is NOT sufficient to allow job F to start -- the predecssor job(s) must also complete before job F can start. Note that job B does NOT trigger job F.

And there's not really a question of which has more benefits -- they are both used for different purposes.

Thanks Robert.

I'm very new to Mainframes and these terms confuses me.

CA-7 has a Primer manual. You would do well to find a copy of that manual and study it carefully, including the Glossary.

Hi,

I have got the reference manual. It might be useful to someone like me:
