Chris,
You can use it. I guess regardless of versions if you have classes12.zip then for OCI (Oralce.jdbc.driver.OracleDriver - Please check it.) its the same class name to refer as wMDB adapter you use it.
Or you can directly use the different URL then thin jdbc URL.
(jdbc:oracle:oci:@“your db name”)
But this means you are using JDBC-OCI not the direct OCI ( c calls). I dont know how much performance improvement you will get if thats your goal is.
