Yes top or topas is good for this as well as vmstat and the sar suite - what you need to identify from each of these is where the bottleneck is - is it that your cpu time is in wait on io ? if so you have a fileio issue which could be lots of dynamic files splitting or lots of secondary overflow somewhere. If the wait on io is low but user cpu is high then it is actual cpu usage that is the bottleneck and you may have to visit some code to re engineer.

It'll give you an overall view of what's going on with the system, including per/processor utilization, per/process information, and disk utilization information. The "h" key while in the program provides a bit more useful information on toggling between screens and what it'll do than does the man page. HTH Drew -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of ericro Sent: Wednesday, March 04, 2009 1:59 PM To: [email protected] Subject: [U2] Performance monitoring We run an IBM P570 with 12 processors running Universe 10.2.4, average of 400 users against at EMC DMX4500 disk array. 20 file systems with each about 45gb, 60-80% utilized striped across 94 disks. We do tons of batch processing at night and our rate of data change is about 175GB an hour at night. We're running into some performance issues, jobs taking much longer, keyboard response slow, editing single records taking a long time, etc. and want to really dive in to see what's going on. We've looked at file sizing and have done a fair amount of resizing, but to little avail. Does anyone have any tools, or know of any tools, similar to Oracle, that can really give me insight into what's happening with a given user session at any time? I know I can do port.status and find the address in the code and see what's being executed at that time, but I want something more that will show memory utilization and other stats like that. Any help would be appreciated. -- View this message in context: http://www.nabble.com/Performance-monitoring-tp22336819p22336819.html Sent from the U2 - Users mailing list archive at Nabble.com. ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
