Fusion.FND_Session_MGNT Exception in JDev 11.1.1.5.0

Question

Hi ..
I am working with ADF and Jdev. I created an EO from a table and setting a column as the history column 'Created by' , threw me the following exception, but the stack trace with the error on getting the user id. I unchecked the history column for that table. Now it is throwing the same error on fetching the language details. I think the following error is something other than the history column/language. I am not able to get the source of the error. It would be great if anyone can point me to the source of the issue. The exception is as follows..
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.sql.SQLException, msg=ORA-20001: APPLCORE--20001: Invalid session B41C3E46A17718FCE040449830F179B3 specified in attach to ap6059fems:ems7689

Hi,
I got the same issue in my application. I debugged into this and found the following reason for this issue..
In my application, the sessionid id getting created in one Database and the application DB is connected to someother. When multiple databases are involved, then this issue came for me.
I did the following to fix this issue and it worked for me.
Goto AM and right click on it and then click on configurations.
Then a new window will open up and in that Window, select AMLocal and then click on edit button. A new window will open up. Here select the Connection Type as JDBC Url and select the Application DB url in the connection Name.
This change resolved my issue as it will create the session id in the ApplicationDB itself..
Cheers,
