Check your DB resource usage first: SELECT * FROM v$resource_limit WHERE resource_name IN ('processes','sessions'); Check to see if your MAX_UTILIZATION for either your Processes or Sessions is getting too close to the LIMIT_VALUE. If yes, you should either: Use DB Connection pooling to share Connection objects between threads. Or, Increase the number of processes/sessions that Oracle can service simultaneously. Actually, Connection Pooling (#1) should always be done. An application cannot scale up otherwise. Check Apache Commons DBCP for details. For #2,

After some uncertain time this always runs repeatedly on errors of this kind: 12:19:31,488 DEBUG [MaintenanceUtil:64] Executing com.liferay.portal.convert.ConvertDocumentLibrary 12:19:31,497 INFO [ConvertProcess:41] Starting conversion for com.liferay.portal.convert.ConvertDocumentLibrary 12:19:31,537 DEBUG [MaintenanceUtil:64] Migrating 276 document library files 12:21:07,739 ERROR [DatabaseFileSystem:225] failed to initialize file system java.sql.SQLException: Listener refused the connection with the following error: ORA-12519, TNS:no appropriate service handler found (stacktrace follows...)
