Application hangs and database time outs must be understood from the side of the application that is experiencing problems.

That being said, Cary Millsap has an excellent book "pretty much all about" how to use raw trace data and you should pick up and read "Optimizing Oracle Performance". Personally I recommend looking at the free utility orasrp which does a much better job ( imho ) than tkprof at breaking out important info from a 10046 trace. Cary Millsap's company hotsos does sell a commercial version of a resource profiler ( which is apparently very good ) but orasrp to me does all that is required.

Do you have any locking or latching issues when the application hangs are being experienced?

What kind of connection type is the application using?

What verison of oracle and running on what platform? Received on Sun Jan 06 2008 - 18:24:56 CST
