A couple of gotcha’s here…
If you get an error saying that OC4J configuration issue <blah blah instance> not found (often TSH1), check the ORACLE_SID variable to make sure it’s correct. The ‘$ORACLE_HOME/bin/emctl start dbconsole’ command should now work. Check this by looking at http://servername/1158/em (by default)
The other one is that when you start the Enterprise Manager first time and log in, you get a ‘java.lang.excception no such metric’. If this is the case, then under Related links, check the Monitoring Configuration and make sure that the dbsnmp user has been set up correctly i.e. with the correct password. Test the connection from there and the problem should go away.
