I got some authoritative info from a DataGuard PM:

With physical standby, supporting distributed transactions should not be an issue - provided Max Availability or Max Protection is used
(that ensures that the standby has all the changes associated with the
distributed transaction). For logical standby, if the primary database
(that participates in the distributed transaction) is RAC, and also in
11g, then logical standby doesn't support the distributed transaction if the underlying transactions are tightly coupled. The reason is that in 11g, tightly coupled transactions can span RAC instances, and logical standby doesn't support that yet. Received on Tue Apr 29 2008 - 14:58:52 CDT
