RE: Multi threaded server configuration puzzle

Replies:
You can add it to the PC hosts file in \windows\system32\drivers\etc

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
<node>.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
