HI,

How to identify a particular job is dependent on another job and how to find sequence of jobs which are dependent on each other?

Which scheduling product you are talking about?

Hi,

You can look in the dataset which has all the scheduling instructions. For example see below

JOB AAAAAAA
SUBAPPL GOOEAE60 WAIT
SCHID = 31
/* TOPJOB = VVB$DMMY.031 */
AFTER ADD(VVB$DI20.031 VVB$DI30.031 VVB$DI40.031 VVB$DI50.031 +
)
NOTWITH (CCLEAE3- CCLEAE9- CCLUAE3- CCLUAE9- CCMEAE3- CCCEAE9- +

If you have access to all the jobs (jcl with procs expanded and parms substituted) then it's possible to build a dependency graph of jobs and datasets that show what jobs create dataset X, what jobs reference dataset X, which jobs modify dataset X, which jobs delete dataset X. In this way it is possible to get some idea of what the job dependencies are without schedule information.

Problems arise when: dataset X 'wraps around' to the next batch cycle (aren't created or destroyed), dataset X is created/destroyed multiple times in the same batch process, GDGs, I haven't thought thru how to handle these, may not give meaningful information. Plus various other difficulties.
