I set up Personal Oracle set up on an external hard drive ("E:\"). Everything was fine, ODBC drivers worked great.
Then I got a 2nd external hard drive, and it somehow took over "E:\" drive and my first drive (with Oracle) became "F:\" drive.
I got most things back in order by editing the Registry, so my IDE (Pl/Sql Developer) was out of commission until I changed the Registry, that's fine now.
But now I can't create an Oracle ODBC driver. I went back to the Registry and changed "Oracle in OraHome92" in ODBCINST.INI to point to "F:\" drive. That allowed me to start to set up an Oracle ODBC connection, but when I went to test the connection, I got an error:
"Unable to connect. SQL State = IM004. [Microsoft][OCBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed"
Any ideas? I looked around in the Registry for something like this but with no luck.
