you need to set the instnace_name parameter on the pc tnsnames.ora also in the listener.ora if havent set it up setup ipc the ipc key would be ideally the sidname.

Also you can modify the DNS suffix for network settings to default to that domain.

Subject: Multi threaded server configuration puzzle

Oracle 8.1.7.4, AIX 5.2

I am trying to configure the multithreaded server. Connections work correctly from other AIX boxes, but from a PC based client I get:

TNS-12545: Connect failed because target host or object does not exist

If I add (SERVER=dedicated) to the the tnsnames.ora file on the client, I get a connection, but, of course, not the shared connection I was trying for.

The trace file is shown below ( I have changed some of the network information for security reasons).

The problem seems to be the lines:

nttbnd2addr: looking up IP addr for host: node2 nttbnd2addr: *** hostname lookup failure! ***

Note that several lines above this point, I got:

nttbnd2addr: looking up IP addr for host: node2.e.blrf.com

nsopen: opening transport...
nttcnp: Validnode Table IN use; err 0x0
nttcni: trying to connect to socket 684.
nttcon: set TCP_NODELAY on 684
nsopen: transport is open

which seems to indicate sqlnet made the initial connection.

The node where the connection works has an ip addresses in the form .e.blrf.com and thus presumably understands that node2 translates to node2.e.blrf.com. I verified that I can ping node2 from the node where the connection works. To ping that node from the PC where the connection does not work, I have to give the complete address (node2.e.blrf.com).

How do I fix this?

Thanks,
Peter Schauss
