BEA 100028 Could not deserialize session data.

Question

Hi there,
We have a production system which is running WL 8.1 which our J2EE application on top.
In the WL domain logs the following error occurs :
####<Jan 31, 2007 8:50:07 AM CET> <Error> <JDBC> <viepapsro10> <viepapsro10> <ExecuteThread: '0' for queue: 'JMSStore<viepapsro10JDBCStore>.ioThreadPool'> <<WLS Kernel>> <> <BEA-001112> <Test "SELECT 1 FROM DUAL" set up for pool "com.jr.jms.jdbcstore.cp" failed with exception: "java.sql.SQLException: OALL8 is in an inconsistent state.".>
####<Jan 31, 2007 8:50:34 AM CET> <Error> <HTTP Session> <viepapsro10> <viepapsro10> <ExecuteThread: '2' for queue: 'weblogic.admin.RMI'> <<anonymous>> <> <BEA-100028> <Could not deserialize session data.

BEAs explanation is :
BEA-100028
Error: Could not deserialize session data.
Description
Could not deserialize session data.
Cause
Failed to deserialize session data.
Action
Make sure the object you are putting into the session is serializable and also the non-transient object it aggregates are also serializable.
If any of the non-transient objects in the entire object graph are not serializable, you will receive this error message.
which doesn't make a great deal of sense to me, can any one shed any light on what exactly is going on?
Kind Regards,

hi,
seems like your connection has gone bad, this could happen for a number of reasons I guess. Here it could be either a misconfiguration of the DB driver against the DB version, or perhaps the session data is simply to big.
google for OALL8 and look for a solution there.
