Dequeue with wait=10 hangs forever

Question

I created a queue on 9i with
EXEC DBMS_AQADM.CREATE_QUEUE_TABLE (queue_table => 're2_t', queue_payload_type => 'SYS.AQ$_JMS_TEXT_MESSAGE', multiple_consumers => FALSE);
EXEC DBMS_AQADM.CREATE_QUEUE (queue_name => 're2', queue_table => 're2_t', max_retries => 2147483647);
EXEC DBMS_AQADM.START_QUEUE (queue_name => 're2');
if i execute
declare
do dbms_aq.dequeue_options_t ;
mp dbms_aq.message_properties_t ;
mhandle RAW(16);
message sys.aq$_jms_text_message;
begin
do.wait:=10;
do.navigation:= DBMS_AQ.NEXT_MESSAGE;
dbms_aq.dequeue(
queue_name=>'re2',
dequeue_options=>do,
message_properties=>mp,
payload=>message,
msgid=>mhandle);
end;
then the dequeue will not wait for 10s. It will just wait forever.
I have set the aq_tm_processes=1 and job_queue_processes=1...
Any solutions/hints?

In which mode your database server is running? Probably if its in dedicated mode it will hang u can check it by changing the database mode.
