10.2.0.4 Upgrade performance slow [message #392575]

The other day upgraded from 10.2.0.3 with some one-offs to 10.2.0.4. On the 10.2.0.3 server things run to user expectations, 4-10 second turn around on java-type reports. On the 10.2.0.4 upgrade server, the same queries are running in 55sec+.

Does anyone know of anything internal/undocumented that might have caused this. I am currently using the sqltxplain tool to gather data from both servers.

thanks in advance

Ed

Hello,

Welcome to OraFaq !!!

It's depents your configration (from OS and database level)

Post your explain plan stat. report with SQL query; We can try to solve your issue.

Also you may need to run statspack/awr report.

PS: Don't start same thread.

It appears you have 2 separate systems.
Prior to the upgrade how did the query run on both systems?
What is Operating System name & version on both systems?
Compare & contrast the Oracle data between the 2 systems.
