Hello Group,

we have several Oracle DB Instances running on this W2k3 Server.

When I try to log in one of these instances, our test-Database rrpt2, I get

ora-16237 PACKET RECEIVE FAILED (or something similiar in German).

sqlnet.log:

***********************************************************************
Fatal NI connect error 12637, connecting to:

"TNSPING rrpt2" works fine.

I can connect to the other databases on the server.

How can this be solved?

Best Regards

Is any type of virtualization involved here?

Hi BlackSwan,

there is no virtualization involved.

The rrpt2-instance used to work!

What has changed since it worked?

Have a look for additional information in the listener.log file on the server, if any error is showing up there.

Hi ThomasG,

as far as I'm concerned, nothing has been changed, or nothing I'm aware of being important.

The listener log doesn't report much. I searched the log for the database in question and found these entries (there are more of course, but they all look the same to me).

If needed, I can upload a part of the listener.log.

Well. none of those connects are from "imp.exe".

So either you are not connecting to the listener/database you are think you are connecting to, or there is a network problem that completely prevents the connection.

Maybe try the standard Windows troubleshooting step "Reboot everything"?

Hi ThomasG,

the logs wich I posted, are from the oracle managent server-tool.

I tried to connect with "imp system@rrpt2" to the database and got the same error.

I'll try to reboot the server, but are there other ideas?

Not really. There is something wrong on the network level.

You could try experimenting from different machines / client version and to different servers / databases to pin down where the problem is.

Or have a look at the network traffic with wireshark.

Hi ThomasG,

I try to connect to the server not from a client, the enterprise manager is started directly on the DB server.

I would throw away the test instance, if i could...

Enterprise Manager is definitely too "High Level" for real troubleshooting.

Try to get the connection working with SQL*Plus first.

This isn't the 64bit Version of Windows by any chance? There were some similar problems in the earlier versions of 9.2. that were fixed in the 9.2.0.7 patch set.
