IPC timeout issue
Posted: Thu Jun 21, 2012 1:52 pm
Hi All-
I understand from a search here on the same topic that it has been discussed umpteen no. of times, but still I am not able to come to a conclusvie statement regarding the root cause and the resolution.
We refreshed out test enviornment(SMP,8 node) with the production one(SMP, 4 node). There are so many jobs making use of IPC stage which run fine in production(with 512 buffer size and timeout as 10 ) but all such jobs are failing in test environment one after another. We tried with changing the timeout to 60 and that has worked fine.
Not able to understand:
1. how do the jobs run with similar configuration in production ?
2. Is there a way to propogate the buffer size and timeout as set in administrator to the IPC stages? As there are lot of jobs and it would required a continuos monitoring of the load otherwise.
3. What's the link b/w setting at project, jobs and IPC stage level ? we have timeout in admin set as 600, at job level we have 'Use Project Defaults' but with in IPC stage we have as 10.
4. What i understood from documentation is IPC(inter-process) works for MPP, while in-process buffering for SMP. so as we have SMP here, shouldn't in-process buffering been used while designing jobs ?
DS v 7.5.3
