Connection Events Are Not Raised When Logical Connection Is Closed In JDBC Driver 12c (Doc ID 2400375.1)

Last updated on MAY 24, 2018

Applies to:

JDBC - Version to [Release 12.1 to 12c]
Information in this document applies to any platform.


In Oracle JDBC Driver or later, connectionClosed / connectionErrorOccurred events are not raised when a logical connection is closed.

This results in possible connection leak in some connection pool managers which are used in connection events implemented by javax.sql.ConnectionEventListener.

Interface ConnectionEventListener

 If using Universal Connection Pool (UCP), connection leak does not occur since UCP does not use these connection events for managing connections.
