My users have a standard Oracle Client 11g installation with ORACLE_HOME, and I need to add the 64-bit ODBC driver. It appears the 11g driver is available only with the Instant Client. I understand I can install the 11g Instant Client with 64-bit ODBC into a separate folder on my machines, and then add the IC folder to my PATH statement. My question is, how can I do this without affecting my default Oracle Home? Can I PATH to only one folder (IC or Home)? I guess basically I need 64-bit ODBC connections using the IC, but everything else continuing to use the original Oracle Home.
