ADF: the oci driver

Ok so we had a requirement to check if the oci driver would work with ADF. So here are the steps I followed to get it working quite simple I think. Will post here if there are any problems with using the driver but with a quick scan test everything looks ok.

1) Installed the oracle client on our weblogic box.
2) Replaced the ojdbcdms.jar reference in the weblogic classpath with the exact version that comes with the client (VERY important)
3) changed my connection string to jdbc:oracle:oci:@

Things that will be investigated : Client side caching, speed tests, amount of connections

Notes: UnsatisfiedLinkError - ocijdbc11.dll not found
Change your path on your system to have your client library location as the first in the list - ie for me I installed my client to C:\Oracle\11.2.0\client64 so that dir must be the first entry in my path.

java.lang.UnsatisfiedLinkError: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()IYou are using the incorrect version of the ojdbc driver make sure you are using the one that came with the client and it is the first driver weblogic loads.

Shortcut to test :
Rename this file to  ojdbc6dms.back
[your middleware install location]oracle_common\modules\oracle.jdbc_11.1.1\ojdbc6dms.jar

Copy your ojdbc6dms.jar from your client (or download from Oracle)  to the above location. Restart weblogic.


  1. Hi Donovan,

    Do you have any idea what could be the problem if I'm getting this error:
    java.lang.UnsatisfiedLinkError: orageneric10 (Not found in java.library.path)

    This is happening when I'm executing the below code:
    String temp = oracle.xdb.XMLType.createXML((OPAQUE)rs.getObject(1));

    Also, I downloaded INSTANT CLIENT, could that be the problem?

    1. Hi,

      Any UnsatisfiedLinkError mostly have to do with dll/so files not being on the path. (I assume you are running on windows - linux is a bit different let me know if you are running linux)

      I have the full client installed (on my forms installation) and my dll is in the C:\DevSuiteHome\BIN directory.

      I dont know much about the INSTANT CLIENT but step one would be to do a search on your drive for orageneric10.dll and pop that directory on the PATH (Enviroment variable). If you dont have the dll try the full client.

      Hope this helps.

  2. Thanks for posting this!
    It really helped me out.
