If you are attempting to configure Adobe LiveCycle server using the LiveCycle Configuration Manager (LCM) with an Oracle database, you may encounter the following exception during the DB configuration step:

Reason

This error can occur if you are not using the correct Oracle DB driver, or the correct Java JDK for your platform.

Solution

You should check the Oracle DB driver and JDK version required in the relevant platform matrix.  With LiveCycle ES2 for example the platform matrix is located here:

http://help.adobe.com/en_US/LiveCycle/9.5/supported_platforms.html

So if you were to install LiveCycle ES2 on AIX 5.3 with WebSphere 7, you should be using the 64-bit JDK 1.6 SR7 provided by WebSphere (WAS_HOME/AppServer/java), and the ojdbc6.jar Oracle driver.

Be sure to set the JAVA_HOME and PATH environment variables as instructed in http://help.adobe.com/en_US/livecycle/9.0/prepareinstallsingle.pdf
