CA-7 is an IBM Mainframe Job Scheduling Package, which facilitates the user with various functions like initiating batch jobs, define triggers and monitoring status of Jobs in queues. 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 an automated job scheduler. Jobs can be scheduled to run and manipulate in a variety of ways . Two common terms that have caused confusion are “job triggering” and “job dependency”. 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 from 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.

In other words - CA-7 is Scheduling Software, which distribute or centralize job submission, management and monitoring as you choose and simplify job management by automating as much as possible and provides a simple-to-use interface to manage your environment. CA-7 is sold by CA Technologies.

It is commonly used by banks and other large enterprises with IBM mainframe IT computing platforms. In 1987, Computer Associates took ownership of the product when it acquired its archival, UCCEL Corporation. CA subsequently renamed it from UCC-7 to CA-7, as was done with product prefixes for UCC-1 (tape library management) and UCC-11 (batch job rerun/restart), etc.


CA-7 Commands

Quote:
/DISPLAY,ST=JCL
Use this command to obtain information about the JCL libraries attached to the CA-7. The ST=JCL parameter provides the information about the JCL libraries and their associated ID number.

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

/DISPLAY,PRINT=SCH
Use this command to obtain the information about Schedule Scan (SSCAN). The PRINT=SCH provides the information about SSCAN such as INCR, SPAN, QDWELL intervals and the next run.

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

CANCEL
CANCEL,JOB=jobname or job number,FORCE=YES,REASON=text
Cancels job out of CA-7 Request Queue.
If job is in the Ready or Active queues, cancelling it in CA-7 would not prevent the job from running. It would only prevent CA-7 from tracking the job. If you need to cancel a job that is awaiting execution (ready queue) or executing (active queue), cancel it from SAM or call the operator and have them cancel the job.

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

DEMANDH
DEMANDH,JOB=jobname,SCHID=nnn
Use this command to request a job to run in CA-7. This command will place a HOLD on the job which must be posted. A reason will be required. The SCHID parameter should be nnn if triggering is not to be done. If triggering is needed, then the appropriate SCHID should be supplied. Caution should be used when executing jobs from the batch cycle during the day. Doing so could cause problems during the next nightly cycle.See also RUNH
