What is CA-7?
CA-7 is a Production control system. It’s an online, real-time, interactive system which automatically controls, schedules jobs based on the Date and time, job dependencies and available resources.
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.
