Hi ,

Is there is any tool to predict the down stream critical job completion times based on a completion time of a upstream job,if the upstream job got abended.

Note:
****
I have a list of jobs from JOB1 to JOB5.And all the jobs has scheduled
in OPC(Opertation Planning and Control) as below:

JOB1----> JOB2--->JOB3/4----->JOB5

JOB2 is dependent on the JOB1.If JOB1 get abend and we can give the approximate completion time of the JOB1 and the tool should predict the completion time of the JOB2 ,JOB3...JOBN.

Please help me out for the above concern icon_biggrin.gif .

Thanks,
Gayathiri

No. Who knows how long any particular job will take today in opposition to yesterday. Too many unknown factors involved.

Data volume, other processing, job priorities, resource availability

did You meditate on ...
the elapsed/completion time for a job network is the elapsed time of the critical path

You can forecast TO SOME EXTENT the completion time if You have enough statistical data available
( and take into account the data growth )

if a job is not successfull ( abend is just one of the reasons ) Your analysis is pretty incomplete

the completion time for the rerun of an unsuccessful job is ...

completion time for manual intervention +
( find and fix the real cause, ... ... ... )
( what if the ledger amounts do not reconcile,
quite a bit of manual research and lots of time )

completion time to restore things to the initial status in order to rerun the job +
( predictable from statistical data )

normal completion time

so I would say that the whole question is not likely to get a complete answer


just raising a few issues to meditate on


the tool to carry on the critical path computation is the lesser of Your problems

as a conclusion, while theoretically possible, much less in practice

Yes i agree with xpat there are many unknown factors involve to estimate the completion of a job, volume of adata and ur cpu time. you have to analyze more what date you will predict more volume of data ...etc.

Hi ,

I have found a solution:

Step1:
*****
We can get the average time for the particular job.
Step2:
*****
Expected time to complete = AVG time + Delay time of the Predecessor job.

Solution:
*******
Using REXX, can anyone can guide me that to get an average time of job completion from the "SAVERS" while giving the below inputs to a panel:

1)Job name
2)From date
3)To date

By using the above inputs we can get average time.
