ORA-12203

What is wrong with the installation of Oracle 8i

ORA-12203: TNS: unable to connect to destination

Please Help!!

 

[Marco Kalter]

According to the Oracle Messages Guide:

TNS-12203 TNS:unable to connect to destination

Cause: Invalid TNS address supplied or destination is not listening. This error can also occur because of underlying network transport problems.

Action: Verify that the service name you entered on the command line was correct. Ensure that the listener is running at the remote node and that the ADDRESS parameters specified in TNSNAMES.ORA are correct. Finally, check that all Interchanges needed to make the connection are up and running.

everything is working good, because are Developer 6i forms running, and are working normal, just DOA doesn't connect with this message...

I've made test with "Net8 Easy Config" and the connection is good... maybe some Key in the Registry, perhaps??

the problem is just in one Machine...

Perhaps you have multiple Oracle Homes? Direct Oracle Access will use the Primary Oracle Home, which may be different than your Developer 6 home.
