#### To Edit Connector Connection Pool Advanced Attributes

1. Use the Advanced tab to edit the advanced attributes for a connector connection pool.

   Parameter | Description
   Validate Atmost Once | Amount of time, in seconds, after which a connection is validated at most once. This will help reduce the number of validation requests by a connection. The default value 0 implies that connection validation is not enabled.
   Leak Timeout | Amount of time, in seconds, to trace connection leaks in a connection pool. The default value 0 means that connection leak tracing is disabled. If connection leak tracing is enabled, you can get statistics on the number of connection leaks in the Monitoring Resources tab. To view this tab, go to Application Server > Monitoring > Resources.
   Leak Reclaim | If this option is enabled, leaked connections will be restored to the pool after leak connection tracing is complete.
   Creation Retry Attempts | Number of attempts that will be made if there is a failure in creating a new connection. The default value of 0 implies that no attempts will be made to create the connection again.
   Retry Interval | Specify the interval, in seconds, between two attempts to create a connection. The default value is 10 seconds. This attribute is used only if the value of Creation Retry Attempts is greater than 0.
   Lazy Association | Connections are lazily associated when an operation is performed on them. Also, they are disassociated when the transaction is completed and a component method ends, which helps reuse of the physical connections. Default value is false.
   Lazy Connection Enlistment | Enable this option to enlist a resource to the transaction only when it is actually used in a method.
   Associate with Thread | Enable this option to associate a connection with the thread such that when the same thread is in need of a connection, it can reuse the connection already associated with it, thereby not incurring the overhead of getting a connection from the pool. Default value is false.
   Match Connections | Use this option to switch on/off connection matching for the pool. It can be set to false if the administrator knows that the connections in the pool will always be homogeneous and hence a connection picked from the pool need not be matched by the resource adapter. Default value is false.
   Max Connection Usage | Specify the number of times a connection should be reused by the pool. Once a connection is reused for the specified number of times, it will be closed. This is useful, for instance, to avoid statement-leaks. The default value of 0 implies that this attribute is not enabled.
