Working with JDBC Connection Pools
Description
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.
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.
If this option is enabled, leaked connections will be
restored to the pool after leak connection tracing is
complete.
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.
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.
Enable this option to enlist a resource to the
transaction only when it is actually used in a
method.
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.
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 that thread, thereby not incurring
the overhead of getting a connection from the pool.
Default value is false.
