I have to agree with Anita. This had happend to me.

I had 8.1.7 client on my laptop and was receiving the correct TNS error message when I was trying to connect to a database on the net. We were trying to debug the problem(which turned out to be a firewall issue), so I removed 8.1.7 and installed 8.0.5(they were running 8.0.5, and I thought maybe there was something buggy in 8.1.7 client). Now the TNS error message was the generic message, 12203. I found the real error message(again) when I looked in sqlnet.log.

So it seems that 8.1.7(and perhaps previous versions) client is better at reporting the correct TNS error then 8.0.5.

Find and checkout your sqlnet.log file.

HTH. Has anyone else found this, or understand this?

Mikael,

I suspect there's another error being signaled which isn't being shown. Have you tried saving the results from DBCA as a script and executing the script manually? That might help you diagnose the true problem. I'd also make sure to check the %ORACLE_HOME%\rdbms80\oradim80.log as you can get the ORA-12203 if the services don't get created. Last, but not least, make sure the sid has letters and numbers only, although usually you'll get an ORA-12650 "protocol adapter error" if you use an underscore or other unsupported characters in the sid.

HTH,

• Anita
