Connect to an Oracle database

Question

I\'m trying to connect to an Oracle database but when the the code is executing the line:

con = new OracleConnection(oradb);

It gives this erro

Answer 1

The PATH setting is not necessary. I solved the same issue with a copy of the oraons.dll into dhe ORACLE_HOME\bin folder and after that the installation works.

There is a difference between an Oracle setup via installer and the xcopy depoyment. I don't now why. Both installations had the same registry setting:

HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\ODP.NET\4.112.4.0\DllPath 

and the DllPath points to the BIN folder of the ORACLE_HOME. That means a PATH setting to the BIN folder of the ORACLE_HOME does not help. An additional PATH to the ORACLE_HOME of the client would help. I think that is not necessary. Only a copy of the oraons.dll into the BIN is enough.
