agent port

[sunidba]

Hi,

I have doubt about the port and communication b/n oms and agent.(10g grid control)



$ emctl status agent

Agent URL : https://dbhost01:3872/emd/main/
Repository URL : https://emhost:4888/em/upload



I see the above ports when i check the status from dbhost01. What is the port dbhost is using to Upload the data to the OEM server ??


Is this communication one way ? OR does OMS server also talk to Agent ?

Communication is both ways, host talk to OMS on port 4889 and 1159 and OMS talks to host on 3872 and 1830.

It seems you are using 4888 instead of 4889 (default)

Can you telnet to OMS from host on the ports listed above. Your firewall may be blocking the connection.

Thaks for your reply.

You listed two ports for com b/n oms and agent and vice versa.,

Does the communication happen on both the ports or u just listed teh default ports ?

Also What is the protocl used for this communication ?

Non default was used, as we are already running 10g OEM. 11g is the new installation on the same server.

I am just wondering can we use same ports as old one, parallely.

try doing "emctl status agent" and then

telnet grid_server_name gridport
telnet host_name host_port

Both ports and server names will be listed when you do "emctl status agent".
You need to connect to one server from the other and vice versa specifying
the port. you will then know if a port is open to a particular server.

OEM 11g uses port 7799

[gandolf989]

OEM 11g uses port 7799

Are you sure that that is how it is configured?
Perhaps you are thinking about your Grid install,
and not the Grid install of the person who originally posted the question?

I am talking about the default port, I have no idea how the poster configured.

That's the point Skhanal. You can't say "OEM 11g uses port 7799" if you mean "default port for OEM 11g is 7799" - you have to be specific.
