WS-AT Transactions are Not Supported When Optimization is Enabled

You can configure a web service binding component as either a service or reference to support WS-AT transactions from the Transaction Participation dropdown list of the Create Web Service dialog. WS-AT transactions are supported in composite-to-web service environments, or vice-versa, with the oracle.webservices.local.optimization property set to false.

WS-AT transactions are not supported in composite-to-composite calls, even with the oracle.webservices.local.optimization property set to false.

For more information about the oracle.webservices.local.optimization property, see Administering Oracle SOA Suite and Oracle Business Process Management Suite.
