• A leaked connection is a connection that was not properly returned to the connection pool in the data source.
  • To automatically recover leaked connections, you can specify a value for Inactive Connection Timeout on the JDBC Data Source: Configuration: Connection Pool page in the Administration Console. When you set a value for Inactive Connection Timeout, WebLogic Server forcibly returns a connection to the data source when there is no activity on a reserved connection for the number of seconds that you specify. When set to 0 (the default value), this feature is turned off.
  • See the JDBC Data Source: Configuration: Connection Pool page in the Administration Console.

NOTE:

  • The actual timeout could exceed the configured value for Inactive Connection Timeout. The internal data source maintenance thread runs every 5 seconds. When it reaches the Inactive Connection Timeout (for example 30 seconds), it checks for inactive connections.
  • To avoid timing out a connection that was reserved just before the current check or just after the previous check, the server gives an inactive connection a “second chance.” On the next check, if the connection is still inactive, the server times it out and forcibly returns it to the data source.
  • On average, there could be a delay of 50% more than the configured value.
