Naeem SheerazFeb 18 2011 — edited Feb 18 2011

HI,

We are currently running EBS 12.0.6 ith database 10.2.0.3 multi node env (this is production)
After increasing the RAM in application from 8 to 16 GB and in database from 16 to 24 GB, I start the database and my database running normal but when I starts the application services then CPU Utilization goes upto 70% to 80%, and my all users are seriously facing very bad recponse.

I have no idea what is happning in our system, but when I revert back the RAM's to 8 GB in application and 16 GB in database my application and Database working normal.

Please assist me???????????

Our system specifications are following:
