解决办法:
在weblogic后台:Services->Data Sources-><select the particular Data source> -> Control
this will shows the conditions of the Data source in all servers it has been targeted. Now check the respective server with overloaded issue and do STOP - CLEAR THE CONNECTION CACHE -- START
this is only a workaround. for complete resolution you have to monitor the DB usage and according to that you have to tune the connection pool parameters.
