I am Wayne, I need your help to resolve my issue in oracle database 11g.
1. I installed Oracle 11g Personal Edition, Release 188.8.131.52, 64bits,
2. Test connection(oracle in oradb11g_home1) is successed in data source, odbc,
2. Then, I tried to connect this with Visual Basic(Visual Studio 2010), data connections, add connections, .net framework data provider for oracle,
3. but I received an error message as "Attempt to load Oracle client libraries threw BadImageFormatException."
4. Then, I download the ODAC(184.108.40.206.0) for 64bits, and installed,
5. I tried to test the connection, but failed with error message as stated above,
"Unable to connect SQLState=08004 Oracle ODBC Ora-12154: TNS:could not resolve the connect identifier specified"
Could you please give me a help on this, do I need to install ODAC for 11g Personal Edition ? Please advice accordingly, thanks.
