Hi Christof, With regards to the following solution : "The use of a shared server can also be forced in the datasource definition by by including a full connect string as the jdbc url. This must the include then string (SERVER=SHARED) " Our connection string looks like this : jdbc:oracle:thin:@company105:1576:pprod Could you please let me know, what needs to be modified in the above URL to enforce SERVER=SHARED ?
