Oracle Grid manager does not see database instances?!

[Database Administrator]

I have two lan's seperated by a router.
On lan1 i am running oracle EM-grid control. On lan2 there are
several
oracle databases (all using the grid-agent)
The problem is that i see all targets in grid control (agents,
listener and database instances)
Agents and listenrs are NO problem, but when i try to view in grid
control the database instance i always get the error:
"Io exception: The Network Adapter could not establish the
connection"
or more detailed:

I Think is has something to do whith the router (blocking a port
which
is needed for the action) But i do not know which port to open. Can
someone help?

WHen you installed the agents on the remote boxes, it asked you about
the agent port. Usually 4889. Is that open?

Hi Hans,

Thanks for your reply!
Well, the agents can upload the information to the grid-host. So i
think that port must be open.
I also see all targets in the grid-host (listeners, database
instances, agents).
The only problem i have is when I want to view the details of the
database-instance i get the error.

any more suggestions?

Regards,
Anneke

Did you register the database credentials?

I think you mean configuration of the DB?

What i do is the fololoweing:
1- I go To enterprise Manager Grid control
2- I log in using the sysman account
3- I select "Total Monitored Targets" overview (the number which is a
link)

I now see that all the database instance targets do have a "metric
collection error"
4- I select one database instance.

Now is see that the status is "metric collection error" AND the
message "This database is not configured"

5- I click the button "CONFIGURE"

I get the error "oracle.sysman.emSDK.emd.comm.CommException: DB1: DB1"
AND (when i click next step)
"Please correct the following error(s).
targetName - Name must be specified"

Did someone get a solution to this issue?
I am getting exactly the same error for an instance on a remote location, EM 10.2.0.3 OS is Windows 2003.

I have been struggling for past few days, and not able to monitor the system properly, Listener, host and agent are fine, but instance gives the error:
oracle.sysman.emSDK.emd.comm.CommException: Connection timed out: connect

Any suggestions are welcome.
Thanks and regards,
Sonal.
