In releases before IBM® Integration Bus Version 10.0.0.2, the only
supported transport mechanism to communicate with WebSphere eXtreme
Scale external
grids was Object Request Broker (ORB). In IBM Integration Bus Version 10.0.0.2 and later, both
ORB and IBM eXtremeIO (XIO) transport mechanisms are
supported. You do not need to configure integration nodes to enable or select a transport mechanism;
the transport mechanism that is used is determined by the WebSphere eXtreme
Scale
external grid.
