I'm not even sure you are asking a question in your post since it is basically incoherent and does not make any sense. Perhaps you could restate what you are saying and / or asking?
If you are saying that the job ran late today and did not run late yesterday, and assuming by "ran late" you mean the job took longer than it did yesterday, you need to be aware that there are MANY, MANY, MANY factor that affect the amount of elapsed time a job will take: number of other jobs in system, contention for the channel, contention for the disk volume, relative priority of the jobs in the system, Workload Manager settings, resources needed by your job, etc, etc, etc. I've seen the same job run in 5 minutes one day and over 5 hours another day -- with no changes at all to that job. The difference was that one day the job ran at a time when the system usage was low, whereas the other job ran during month end processing when the system was running at 100% utilization for 36 hours. This is not a CA-7 issue and typically there is little, if anything, that you can do about it -- the operators and system support personnel might be able to help, but in general if the system is that busy, your job will run longer, period.
