How to kill Oracle Enterprise Manager

Many times it shuts down nevertheles the message.
OEM on 10g is terrible bugy!

But I can't start it again, so it must still be running:

>emctl start dbconsole
Oracle Enterprise Manager 10g Database Control Release 10.1.0.3.0  
Copyright (c) 1996, 2004 Oracle Corporation.  All rights reserved.
http://ortopediservice:5500/em/console/aboutApplication
 - An instance of Oracle Enterprise Manager 10g Database Control is already running.

I have all of the following processes running on my machine. I will try to kill them this evening, when no one is using the database. I couldn't see any of the other processes you listed.

Fix

If possible reboot server.

If a reboot is not possible, then try manually killing hung processes.

Step 1
Look at the emctl.pid file in /u02/app/product/oracle/10db/_/

Step 2
Ps -ef | grep <pid from the emctl.pid file>

Step 3
Find the process number in the file and all its child process and kill -9 all process associated with the
EMCTL pid

Step 4
Next do
emctl stop dbconsole - It will do some housekeeping

Step 5
Then do
emctl start dbconsole

Test console
======================================================================

If this does not work (there's no such process as shown in emctl.pid),
remove this file and start dbconsole again.

Actually the root process of OEM in my system is:

oracle    6947  6938  0 Jun22 pts/0    00:00:00 /u01/app/oracle/jdk/bin/java -server -Xmx512M -XX:MaxPermSize=64m -XX:MinHeapFreeRatio=20 -XX:MaxHeapFreeRatio=40 -DORACLE_HOME=/u01/app/oracle -Doracle.home=/u01/app/oracle/oc4j -Doracle.oc4j.localhome=/u01/app/oracle/Europa_research/sysman -DEMSTATE=/u01/app/oracle/Europa_research -Doracle.j2ee.dont.use.memory.archive=true -Djava.protocol.handler.pkgs=HTTPClient -Doracle.security.jazn.config=/u01/app/oracle/oc4j/j2ee/OC4J_DBConsole_Europa_research/config/jazn.xml -Djava.security.policy=/u01/app/oracle/oc4j/j2ee/OC4J_DBConsole_Europa_research/config/java2.policy -Djava.security.properties=/u01/app/oracle/oc4j/j2ee/home/config/jazn.security.props -DEMDROOT=/u01/app/oracle/Europa_research -Dsysman.md5password=true -Drepapi.oracle.home=/u01/app/oracle -Ddisable.checkForUpdate=true -Djava.awt.headless=true -jar /u01/app/oracle/oc4j/j2ee/home/oc4j.jar -config /u01/app/oracle/oc4j/j2ee/OC4J_DBConsole_Europa_research/config/server.xml


Try killing this process.

Note: did u change user oracle to other group? this cause dbconsole to start and stop.... You can check this.
