I'm trying to launch the OPMN-managed process OC4J_EM, which is needed for Oracle's Enterprise Manager. When I run use the startall or startproc command, I get an error:

failed to start a managed process after the maximum retry limit

And am redirected to a log file. Checking this log file, I see the following for each attempt:

11/11/29 14:00:20 java.sql.SQLException: Logical handle no longer valid

Any ideas as to how I can fix this and get OC4J_EM started?

A few comments. 1) Is this Grid control or database control ? 2) The error message is db connection related - are the db and listener up? 3) Can you connect via sqlplus from the em home –  Niall Litchfield Nov 29 '11 at 10:26
