Since dest app is not allowed to poll (why?) the only other option I can think of is "callback procedure". The can be plsql or other types. Look in the AQ manual for details, in certain release of 920x this didn't work correctly, but I am told this works fine in 9206. Never pursued since we don't have 9206.
