Hi Chintan,

First
Are you able to ping the host at TCP/IP level ?

Second
Make sure your SQLNet configuration files are complete

Third
Ping at TNS level

Hi there,

I have had this problem to recently. Did you resolve it? I think it has to do with the configuration stuff of the Config. Assistant. I have yet to resolve it.

Cheers,
Gerard
