Inconsistent job performance
Posted: Sat Dec 20, 2008 1:35 am
Hi
We have a DataStage server (7.5x2) with 2 projects; SysTest and UAT
I have an issue where job performance is not consistent across these projects.
Although job design, job sequencing, file sizes, directory structure - everything appears to be the same.
I've confirmed the projects are setup the same.
A job in one project ran in 1 hour and now runs 5+ hours in the other project.
And just to be interesting, a job ran in 2 hours in one project and then runs only a 1/2 hour in the other.
If this issue happened on the same job(s) or the same spot during the process, I would be able to review and make appropriate job design changes.
But this is not the case.
Our System support people have been monitoring the server but we haven't seen
anything that would cause a job to be long-running (ie. high cpu usage,high disk i/o).
The latest example is a job that ran in SysTest in 1.5 hours and has been running for over 8 hours in UAT.
I'm not sure what else to check.
Any ideas\suggestions are appreciated.
Thanks Debbie
