hi

I have a problem with the connectivity. I have created a dblink to the production database by name livelink. I am able to connect to the production database using the host string but while trying to retrieve any data using the database link, I am prompted with the error :

ORA-12535: TNSperation timed out

We connect to the production database by passing thru the firewall.

Can anyone help me out? This is most urgent.

Thanx

Das
