Managing Connector Connection Pools

On Any Failure	If you select the checkbox labelled Close All
	Connections, if a single connection fails, then the
	application server will close all connections in the
	pool and then reestablish them. If you do not select
	the checkbox, then individual connections will be
	reestablished only when they are used.
Transaction Support	Use the Transaction Support list to select the type of
	transaction support for the connection pool. The
	chosen transaction support overrides the transaction
	support attribute in the resource adapter associated
	with this connection pool in a downward compatible
	way. In other words, it can support a lower transaction
	level than that specified in the resource adapter or the
	same transaction level as that specified in resource
	adapter, but it cannot specify a higher level. The
	transaction support options include the following.
	The None selection from the Transaction Support
	menu indicates that the resource adapter does not
	support resource manager local or JTA transactions
	and does not implement XAResource or
	LocalTransaction interfaces. For JAXR resource
	adapters, you need to choose None from the
	Transaction Support menu. JAXR resource adapters
	do not support local or JTA transactions. Local
	transaction support means that the resource adapter
	supports local transactions by implementing the
	LocalTransaction interface. Local transactions are
	managed internal to a resource manager and involve
	no external transaction managers. XA transaction
	support means that the resource adapter supports
	resource manager local and JTA transactions by
	implementing the LocalTransaction and
	XAResourceinterfaces. XA transactions are controlled
	and coordinated by a transaction manager external to
	a resource manager. Local transactions are managed
	internal to a resource manager and involve no
	external transaction managers.
Connection Validation	Select the Required checkbox to enable connection
	validation.
