CICS Transaction Gateway supports both the LocalTransaction and XATransaction transaction management models.
The xasupport custom property on a ConnectionFactory determines whether transactions use the XA protocol or not.
To enable LocalTransaction support, set the xasupport custom property to off.
Local transactions are not supported when using WebSphere Application Server for z/OS with CICS Transaction Gateway for z/OS in local mode, as the resource adapter provides global transaction support with MVS RRS.
