Open close cics files

But you don't get any feedback, and if MVS is stressed it can ignore commands sent to the console buffer, so it is possible to run the batch job 'successfully' and leave the files open to CICS.

Writing your own tool using EXCI should only take about half an hour or so, and it's much more reliable. Plus you can set a return code so your scheduling software can see if the job worked properly or not.

Coupling Facility structures: review existing RLS lock and cache sizes. Alter files not going to RLS.

DFSMS storage class and data class. More on these as well. Let's look at a couple of interesting issues we came across in our planning. All RLS datasets were: Extended format - we didn't see any reason not to make them extended format and it's required for compacted datasets , though we did not use striping. Our site had a lot of CICS regions for different applications. So, an issue with a CICS region for another application could possibly affect our processing.

Our application relied on CICS files being open. Part 3: Implementation We did this in waves: starting with a couple of files, and having waves of up to 60 files at times. Each wave was done like this: Get baseline performance data. Performance check. Conclusion Wasn't that simple, was it?

David Stephens. They are executed in the CICS region in which the issuing program is running. Posted: Wed Jul 18, pm. More info on how it's being done now I had asked before regarding the extended response-time; When did this begin? Please advise I don't think the slow open response is a new thing. They have made lot of changes to this effort in past couple of years and this problem slow open using eds waapdlok utility is a small piece of the big puzzle.

I did give that info to systems team, as usual, no response from them yet. May be, the only solution is they should not run that step that is opening the files and instead each transactions 1st access will open the files needed.

Thnx for the help. View previous topic :: :: View next topic. Similar Topics. Search file for records that don't fo To re-format the file using SORT card. Read file names from existing file th
