we have a Java Enterprise Application running on Weblogic Server 12c using Spring JDBC 3.2.5 to access Oracle 11gR2 Database. In production environment after some time we got this exception: "ORA-01000 - Maximum open cursors exceeded" and server instance need to be restarted; it seems that open cursors increase more and more until they reach the maximum threshold set on Oracle. Increasing the threshold didn t solve the problem. We check the (very large) source code but we didn t find any point where we miss closing connection, at the moment; moreover we usually don t open and close connections but we use Spring JdbcTemplate to handle database interaction. Could be a Spring problem? Any hints?
It was a bug of that version of Spring. update Spring Library
