Actually, I may have an answer for ya. If you are using the Trial Version CD and somebody else has already installed it, it exports the .exe file and gives you the TNS12203 error.

personal oracle8
Does that mean, the oracle DB is running on the same PC as the designer/2k ?
sorry to ask this, but I have only good experience connecting Oracle Clients (all Windows variants) to Oracle Servers running on an application server (Unix, NT, Netware)
Please let me know if Client and Server are separate machines. If this is true I can help you.
Personal Oracle 8 is a client database. It is Oracle's desktop database. You can run it as an Object-oriented program or interface it with SQL * Plus or SQL Navigator, etc.
Actually, what I should have said earlier is not that it exports the .exe - but if you are installing from the Trial version cd and have already installed a previous trial version, the PO8 will recognize the previous install from the registry settings that the trial version has already been installed once. It will give the end-user a message saying that Oracle.exe cannot be found. Its a marketing thing.
There is a problem in connecting designer/2000 or Developer/2000 to Personal Oracle 8.
The Problem is with sqlnet. If you are connecting Designer/2000 to Oracle 7.x there won't be any problem because both tool and server are SQL*Net version 2 based.
There is a way to connect to personal oracle 8 from
designer/2000 but that it not very easy. But now
there is a patch available on the
oracle FTP server to fix the problem. Download the
executable 23403.exe from
ftp://192.86.154.96/server
T/network/sqlnet and apply the patch.
Hope this will help.
I've had some success connecting Developer to Oracle8 on a Win95 PC... but I've never tried Designer. I'm surprised that you say you can connect Developer but not Designer. Anyway, I thought I'd suggest this, just in case...
This solution is defined in terms of TCP/IP, but the approach should be portable to Netware, etc. Define the SQL*Net connection (Easyconfig should be fine) to use a loopback connection. Configure both Net8 and SQL*Net 2.x (for the client). Use 127.0.0.1 - which is the loopback address - for the hostname of the computer.
Finally, find and run the Net8 listener. It should be in the \orant\bin directory, and will have a name like tnslsnr80.exe, or something like that. It'll start a DOS window, and won't look like it's doing anything, but this is fine. You can minimize the window if you want, to get it out of your way.
I would add both the Oracle startup and listener to the startup folder, so they'll start when you start your PC.

Don't know about from designer 2, but thought I would suggest doing a file find on tnsnames. ora and open it with notepad. Read what it says through there at the bottom. Do any of those codes fit?
Is your database started?
Is the profile for the roles defined?
Sorry if these are elementary questions, but its a start.
