Hi Sandra,

If you talk with your scheduling and/or computer operations people they can give you all of the specifics on which scheduling software your installation uses. They should be able to point you to the manuals as well as your site standards in the use of the product including terminology.

Hi friend


Force Complete
****************************************

CA-7 is our automated job scheduler. Jobs can be scheduled to run and manipulated in a variety of ways. Two common terms that have caused confusion are "job triggering" and "job dependency."
Job triggering means a job's JCL is being pulled into the CA-7 queue for execution. If it has no other dependencies on it, it runs right away. But if there are other dependencies, it will wait for them to be satisfied. In other works, when a job is triggered, it doesn't necessarily run right then.
A job dependency is a job that must complete before the job waiting in the queue can run. Upon successful completion of the preceding job, the job waiting in the queue will be submitted. However, if the dependent job does not complete successfully, the job dependency will not be posted.
Also, the terms "force complete" and "cancel" both mean to remove a job form the CA-7 queue. But the results are completely different.
A job is forced complete when it returns an acceptable condition code, or when it does not require an immediate remedy, and the job stream can continue. Forcing a job complete tells CA-7 to treat the job as having completed successfully, and to continue processing. Any dependencies of this job on other jobs will be posted, and any job triggering by this job will be done.
Canceling a job from the queue does just the opposite. The job will be removed from the CA-7 queue, but no job triggering will be done, and any dependencies of this job on others will not be posted. This command is used to stop a job stream.

2. Negative dependency..

i am not sure on this but i suppose
Some jobs can be run parallely but due to wrong dependency/ negative dependency the jobs will be dependent or waiting for a an job to complete

3. The Job with out exec is an Dummy job it is used

Negative Dependency:

************************************************************
The dependent job. For example JOBA1 must run before JOBB will be released. JOBB will only wait for JOBA2 if JOBA2 is on one of the queues when JOBB is requested - a conditional dependency. The dependency to JOBA4 is coded with a / This means JOBB would not be released if JOBA4 has been submitted. Note a second negative dependency the other way round must be added to ensure that JOBA4 would be held if JOBB has already be submitted. The LEADTM field value is not used in with negative dependencies.

Syntax:
UPD,JDEP,JOBB,OPT=A,PRED=JOBA

Thanks,
:)
