We are running a database on a tru64 server. From the "top" command, the CPU is 93% idle, yet I see Oracle processes are intermittently in the STATE - WAIT (top cmd). This also causes slow initial local connection to Oracle DB (e.g connect internal takes 20-30secs). However once you're connected things seem to be okay. I checked the database and we don't have any heavy running. I suspect that one of the root processes is causing this. Any suggestion? Thank in advance?
