Unreachable Agent

Question

I'm new to the tool and have OEM installed on 1 server.
The status of the 1 host I have an agent is "Agent Unreachable". I have ensured that an agent is running on the server. The agent appears to be running on port 1831. When doing emctl status agent, the Agent URL is http://hostname:1831/emd/main.
On the Host targets page in OEM, I see a name called db1p:3872.
I'm new to this, but it appears that the DBconsole is looking for the agent on prot 3872 and its really on 1831.
Am I reading this right. If so, how do I change the port in the DBconsole or agent.
Any other thoughts would help me sleep better this afternoon.
Thanks,
John

Answer 1

I'm sure that I have this configured wrong, but here goes. I'm on an HP UX server. At the present time I am supposed to 1 agent on DB1t and OEM on the same server. The server has 3 oracle instances: HSI1, HSI2, and HSI3.
I have 5 emd.property files. They are located in the following directory:
$ORACLE_BASE/sysman/config/emd.properties
$ORACLE_BASE/db1t_HSI1/sysman/config/emd.properties
$ORACLE_BASE/db1t_HSI2/sysman/config/emd.properties
$ORACLE_BASE/db1t_HSI3/sysman/config/emd.properties
$ORACLE_BASE/oms10g/sysman/config/emd.properties
I modified both the first and last files, but not the middle 3.
Also, this is troubling to me. I shut down OEM using emctl stop dbconsole. Yet I can still call it up from a Web browser. It says that it is stopping, but I can still display the 10g console. I'm using the Grid Control page from the Web, but I'm not sure how to bounce it.
Here is the Emd_properties file. The fifth one:
