AQ Asynchronous Processes Count

Question

Hi,
Oracle 9i Version 2
aq_tm_processes = 2;
job_queue_processes = 20;
Does anyone know if it is possible to have more than 10 AQ callback procedures running at the same time?
I use a PL/SQL callback procedure (asynchronous) that calls a JAVA stored procedure. The procedure simply inserts a row into a table and then sleeps for two minutes. When I look at the rows inserted into my test table it appears that 10 processes are run simultaneously. I would like to increase this number if possible.
Any ideas or information is appreciated.
Thanks,
Keith

I added a subscriber as you suggested and then registered the pl/sql function.
When I enqueue messages to the queue, the callback procedure is still not
notified that the queue received a message....
Created a subscriber:
DECLARE
subscriber sys.aq$_agent;
BEGIN
subscriber := sys.aq$_agent('derive_sub','derivations.S3068_QUE',NULL);
DBMS_AQADM.ADD_SUBSCRIBER(queue_name => 'S3068_que', subscriber => subscriber);
END;
registered the pl/sql procedure as such:
declare
reginfo1 sys.aq$_reg_info;
reginfolist sys.aq$_reg_info_list;
BEGIN
reginfo1 := sys.aq$_reg_info('derivations.S3068_QUE:derive_sub',dbms_aq.namespace_aq, 'plsql://derivations.notifycb',HEXTORAW('FF'));
reginfolist := sys.aq$_reg_info_list(reginfo1);
sys.dbms_aq.register(reginfolist,1);
END;
enqueued the queue:
DECLARE
enqueue_options dbms_aq.enqueue_options_t;
message_props dbms_aq.message_properties_t;
message_handle RAW(16);
message message_type;
BEGIN
message := message_type('TEST','TESTING');
dbms_aq.enqueue(queue_name => 'S3068_que',
enqueue_options => enqueue_options,
message_properties => message_props,
payload => message,
msgid => message_handle);
Commit;
END;
Any other ideas would be appreciated.
