I have a Windows XP host running VMWare Workstation 7, hosting a guest running Windows 2003 with Oracle database 9i.

It is a copy of my original physical server which I converted. I also edited listener.ora and tnsnames.ora to the IP of cloned server. The network adapter is bridged, so vmnic receives the IP from DHCP and I can ping from my local network.

The Database is up and running. On my Windows XP host, I installed the Oracle Client 11g and TNSPING is working. I can connect my application to the database.

The problem is: I can't connect from another Windows XP PC from my network. I also installed Oracle Client and changed listener.ora and tnsnames.ora to the IP of cloned server. The error is:

TNS-12535 TNS:operation time out.

The firewall is disabled on both sides. Ping is working. Is it a problem with the bridged connection?

FWIW the problem is not with Oracle but with the VM, I'm almost certain of it. Do you have any other servers on the laptop besides Oracle that can be tested for communication? I imagine it is a problem with the bridged connection. (keep in mind that WAMP is an easily installed product stack to test communications) – jcolebrand Jul 20 '11 at 16:14
