how do get oracle agent to start up

I have a database and I installed Oracle agent so that I could manage the database from the EM Grid control server. Then I created a database and made sure configure the database with Enterprise Manager was checked and use Grid Control for Database management was selected. It created the database successfully. I checked the agent and it wasn't started so I tried to start it. it appeared to be starting the agent then I got the following message: Starting agent ................................. failed.

There were no error messages and no log mentioned. So I don't know how to troubleshoot this. Does anyone know what could be wrong and how I can fix it?

For Oracle there is always a log.

Check under: agent10g/sysman/log

You can also try starting it from a command prompt:
emctl start agent

This should provide additional information.

>>I have a database and I installed Oracle agent

Did you install a different agent before you created the database and told it to use Grid Control?

I installed the agent then I created the database the agent is version  

there is a trace file that has entries like
2012-05-23 19:47:34 Thread-45 ERROR pingManager: nmepm_pingReposURL: Did not receive a response header from repository

THe emctl.log has entries like

i think that is the problem when I check the agent status or try to start the agent the header looks like this

Oracle Enterprise Manager 10g Database Control Release

Agent is Not Running

when I execute runInstaller and check installed products it shows agent installed version

I have a variable AGENT_HOME and it is pointing to the directory where the agent is installed and I also have the agent_home/bin directory in the path variable

My Oracle_home is pointing to the oracle database

Have you tried using the agent?  For grins I would uninstall everything and stay with

I've never used Grid Control outside of class but going from memory, the agent should know how to talk to a Grid install.

ironically now it is pointing to the right emctl and the agent has started. but now it shows the upload manager as disabled and the grid control doesn't show the database server. It is suppose to see it automatically but it doesn't

It has been many years since I messed with Grid Control.

Can you not go into Grid Control and 'Discover' the node?

I tried i keep getting response that grid automatically sees or discovers host
