Propagation between two type raw queues

Question

Good day.
I want to enable propagation between two type raw queues -
according to documentation:
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/server.102/b14257/aq_intro.htm#CHDCEFBD -
"+Propagation of Messages with LOBs+
+Large Objects can be propagated using Oracle Streams AQ using two methods:+
+* Propagation from RAW queues+
+* Propagation from object queues with LOB attributes+"
My example:
begin
DBMS_AQADM.create_queue_table(queue_table => 'SRC1_QT',queue_payload_type => 'RAW',multiple_consumers => true);
end;
begin
DBMS_AQADM.create_queue(queue_name => 'SRC1_Q',queue_table => 'SRC1_QT');
end;
begin
DBMS_AQADM.create_queue(queue_name => 'DST1_Q',queue_table => 'SRC1_QT');
end;
begin
DBMS_AQADM.start_queue(queue_name => 'SRC1_Q');
end;
begin
DBMS_AQADM.start_queue(queue_name => 'DST1_Q');
end;
declare
c number;
begin
dbms_aqadm.verify_queue_types(src_queue_name => 'SRC1_Q',dest_queue_name => 'DST1_Q',rc => c);
dbms_output.put_line(c);
end;
Last PL/SQL block returns
VQT: new style queue
+0+
Does it means that queues incompatible?

Answer 1

Yes, it works - and I think dbms_aqadm.verify_queue_types shows wrong answer:
DECLARE
subscriber sys.aq$_agent;
BEGIN
subscriber := sys.aq$_agent('SRC1_SUBS', 'DST1_Q', NULL);
DBMS_AQADM.ADD_SUBSCRIBER(queue_name => 'SRC1_Q',
subscriber => subscriber);
END;
begin
dbms_aqadm.schedule_propagation(queue_name => 'SRC1_Q');
end;
DECLARE
enqueue_options     dbms_aq.enqueue_options_t;
message_properties  dbms_aq.message_properties_t;
message_handle      RAW(16);
message             RAW(10000);
BEGIN
for i in 1..100 loop
message :=  utl_raw.cast_to_raw(to_char(i));
dbms_aq.enqueue(queue_name => 'SRC1_Q',
enqueue_options      => enqueue_options,
message_properties   => message_properties,
payload              => message,
msgid                => message_handle);
end loop;
COMMIT;
END;
select QUEUE,MSG_STATE,COUNT(*) from AQ$SRC1_QT T group by QUEUE,MSG_STATE
QUEUE      MSG_STATE      COUNT(*)
DST1_Q     READY           100
SRC1_Q     PROCESSED       100
