Dependencies

DJC application

Description of usage

DJC allows users to control the order of execution of jobs that depend on the completion of other jobs. They can use JECL to organize jobs that depend on each other into DJC Groups, and control the order of execution of jobs within a DJC Group. A DJC dialog under ISPF allows users to display and modify DJC Groups, DJC Events, and jobs in DJC Groups.

DJC provides several commands to display and control DJC Groups and jobs.

To display DJC jobs

/DJC DISPLAY JOBS ALLJOBS

This results in a display of all DJC jobs:

DTM6420I DJC DISPLAY
Job DQC021A in BENCH.D016 Waiting SUBMISSION
Job32158 DJC021 in BENCH.D016 Ended Mar 12 11:52:17

...

To display jobs in a DJC group

This command requests a display of all held jobs for a specific DJC Group:

/DJC DISPLAY GROUP PBC HELD

This results in a display similar to this:

To display information about a specific job

This command requests a display of information about a job:

/DJC DISPLAY JOB 3298

The resulting display shows the DJC dependencies for the job, as well as their status:

DTM6420I DJC DISPLAY
Job03298 COS003 in COS.WEEK1 Executing
- RUNIF %COSSIG CODE EQ 10 (T) Prev

In the line showing the DJC dependencies:

• (T) indicates that the signal %COSSIG has been set to the code 10 by another job in the DJC Group.

• Prev indicates that the signal %COSSIG had been set to the code 10 at the time it was evaluated for job 3298, but has since been altered by another job in the DJC Group and might no longer have this value.

To display events

/DJC DISPLAY EVENTS

This command displays all DJC events:

DTM6420I DJC DISPLAY
Event %COSSIG in COS001
Event %READY in DBMAINT
Event %ITSDONE in PR06WEEK
...

You can also display the details for Events:
