DBConsole Not starting: An instance of Oracle Enterprise Manager Database Control is already running (文档 ID 1401794.1)

Applies to:

Enterprise Manager for Oracle Database - Version 10.2.0.4 to 11.1.0.7 [Release 10.2 to 11.1]

Information in this document applies to any platform.

Symptoms

Attempting to start the DBConsole fails with:

- An instance of Oracle Enterprise Manager Database Control is already running.

Issuing emctl stop dbconsole returns a status saying that it is successfully stopped.

emoms.trc log shows the following:
2012-01-26 07:56:56 Thread-12968 WARN http: snmehl_connect: connect failed to (<MY HOST DOMAIN:PORT>): Connection refused (error = 146)
2012-01-26 07:56:56 Thread-12968 ERROR pingManager: nmepm_pingReposURL: Cannot connect to <MY HOST DOMAIN:PORT> /em/upload/: retStatus=-32
2012-01-26 07:57:13 Thread-12971 ERROR upload: Error in uploadXMLFiles. Trying again in 300.00 seconds.

Changes

Cause

Process did not shutdown cleanly form a previous run.

Solution

1) Ensure all dbconsole related processes are not running:

ps -ef | grep dbconsole
ps -ef | grep emagent

Kill <returned pid's above>

If any processes do not terminate within a few seconds, issue this command:

kill -9 <residual, unterminated pid's>

2) Rename/remove the existing pid file: $ORACLE_HOME/<hostname>_<SID>/sysman/emctl.pid

3) Start back the DB Console.
