Instant client and Oracle 9 on the same machine

[TommyN]

Hi,

I have a problem on a machine where both Oracle 9 and instant client is installed. Even though I modify the PATH variable to point at the instant client folder, this client will not be used unless I rename/remove the "Oracle" entry in HKEY_LOCAL_MACHINE/SOFTWARE/. Is there another way of getting the DOA components to use the instant client?

Thanks,
-Tommy

Direct Oracle Access will first use the information from the registry, so your Oracle9 installation will have precedence. To use the Instant Client instead, you need to set the OracleCI.OCIDLL variable, and set it to the \oci.dll file path & name.
