Hence, the listener is dropping and blocking new connections for a while. 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, open a new SQL*Plus session as SYSTEM and run: ALTER system SET processes= scope=spfile; to increase backend concurrency. Then RESTART the Database. IMPORTANT! share|improve t

ORA-12519, TNS:no appropriate service handler found up vote 0 down vote favorite I'm building a JSF2 app with GlassFish, Hibernate, Spring (for transaction mgmt), and Oracle 11g. After the application has been running for a while, http://stackoverflow.com/questions/6795580/why-do-i-get-this-oracle-connections-error-ora-12519-tnsno-appropriate-servic the app fails to query the db and I get the following error in the GlassFish log: Caused by: java.sql.SQLException: Listener refused the connection with the following error: ORA-12519, TNS:no appropriate service handler found This sounds like Oracle is running out of connections, but the processes in Oracle are set to 150 (which I think means it will accept 150 connections) which seems like plenty. My Hibernate config appears to be set to use 1 connection (as follows). Why would the application be opening more than 150 connections? And how would you suggest I address this?

ORA-12519: TNS:no appropriate service handler foundtips Oracle Error Tips by Burleson Consulting Oracle docs note this about ORA-12519: ORA-12519: TNS:no appropriate service handler found Cause: The listener could not find any available service handlers no appropriate that are appropriate for the client connection. Action: Run "lsnrctl services" to ensure that the instance(s) have registered with the listener, and are accepting connections. ORA-12519 and Shared Servers: What has commonly happened here is that moving from a dedicated server to a shared server (MTS) ORA-12519 is thrown even though you have correctly changed al of no appropriate service the necessary parameters. ORA-12519 and listener configuration: ORA-12519 occurs here because the listener has not been properly set to the default port and the PMON automatic listener registration fails with ORA-12519. You may also notice with this ORA-12519 error that the RDA LOCAL_LISTENER reads NULL. To resolve ORA-12519, register the listener manually after the MTS change if you still wish to use non-default ports. ORA-12519 and "processes" parameter: Also, on Oracle DBA Forums, there is information referring to ORA-12519. Here, it is pointed out that ORA-12519 can be caused by low "processes" values, which can be resolved by increasing he DB parameter, "parallel_max_servers". Also, ORA-12519 can be thrown because of DB and client versions which do not match.

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...) After this error the application goes on until next occurrence of that error. Monitoring the listener.log while executing the migration-application shows a massive increase of connection-requests.
