Because of the overheads associated with XA transactions, the use of network and processor resources is higher when using the XA transactional support provided by cicseci.rar with the xasupport custom connection factory property set to on.
The decision on how to configure the resource adapter depends on the transaction support required by the JEE application. For more information seeTransaction management models.
For transactions that use XA, set xasupport to on in the connection factory. For performance reasons, you should define a second connection factory with xasupport set to off for those transactions that do not use XA.
If the Client application is running under WebSphere® Application Server, connection pooling can be used in remote mode to reduce the overheads associated with establishing connections.
