Environment

Component: APPMGR

Cause

This is caused my a mismatch of the installed Oracle JDBC drivers and the version of Oracle the instance is running against.

Example:
Oracle JDBC driver 11.2.0.4.0
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
 

Resolution

Download the correct ojdbc.jar file from Oracle and replace this in the master's $AW_HOME/web/classes or %AW_HOME%\web\classes (Windows OS) directory.
