Contenion Issues
Posted: Sat Jun 25, 2011 11:55 am
Hi,
We are trying to avoid Contenion Issues the Jobs has over the Control card. We had the following Fix to handle this in Rexx but later realised that this is not giving us the expected results.The fix was that we have a Sleeper Process in place so that the whenever the first DISKW to Write the contents from one control card to the another fails the process goes into a sleep mode for 12 seconds and later do a Write if successful. The sleep process is set for 5 intervals of time from the first unsuccessful Write.If the contention still persists even after 60 seconds we throw an error.
When the Job ran last time there was a contention issue over the control card and the Job went to a sleep mode for 24 seconds and later altered the control card
(As per the SYSOUT ). But we later actually realised that contents were not actually written .
Can someone please suggest some possible reasons for this
