Can a dequeued message be under the authority of the queuing user ?

Question

Hello,
I am testing AQ on an 11.2.0.1.0 database and I am missing something...
Here is my test case:_
1) I have a queue created in COM_OWNER account. I created a callback procedure with dbms_aq.register. This procedure just create a row into log table.
2) The user FBOUCHER issue a dbms_aq.enqueue.
3) I query the log table. The row was created by SYS ??.
Can my callback procedure run under the authority of FBOUCHER instead of SYS ?
I specified "authid current_user" for my callback package and used USER to insert into log table.
Thanks for your help.
Here is my complete test case:*
Following scripts are run from COM_OWNER Oracle user on a 11.2.0.1.0 database.
create or replace package test_aq authid current_user is
procedure getmessage(context in raw, reginfo in sys.aq$_reg_info, descr in sys.aq$_descriptor, payload in RAW, payloadl in number);
end;
create or replace package body test_aq is
procedure getmessage(context in raw, reginfo in sys.aq$_reg_info, descr in sys.aq$_descriptor, payload in RAW, payloadl in number) is
begin
insert into log values ('notification received', sysdate, user );
commit;
end;
end;
declare
l_reg_info_list sys.aq$_reg_info_list;
begin
dbms_aqadm.stop_queue(queue_name => 'TEST_QUEUE');
dbms_aqadm.drop_queue(queue_name => 'TEST_QUEUE');
dbms_aqadm.drop_queue_table(queue_table => 'TEST_QUEUE_TABLE');
dbms_aqadm.create_queue_table(queue_table => 'TEST_QUEUE_TABLE', queue_payload_type => 'RAW', multiple_consumers => FALSE);
dbms_aqadm.create_queue(queue_name => 'TEST_QUEUE', queue_table => 'TEST_QUEUE_TABLE') ;
dbms_aqadm.start_queue(queue_name => 'TEST_QUEUE', enqueue => TRUE, dequeue => TRUE) ;
dbms_aqadm.grant_queue_privilege(privilege => 'ENQUEUE', queue_name => 'TEST_QUEUE', grantee => 'MAJ_COM');
execute immediate 'drop table log';
execute immediate 'create table log(text varchar2(2000), date_creation date, usager_creation varchar2(30))';
execute immediate 'drop public synonym log';
execute immediate 'create public synonym log for com_owner.log';
execute immediate 'grant select, insert, delete on log to maj_com';
execute immediate 'drop public synonym test_aq';
execute immediate 'create public synonym test_aq for com_owner.test_aq';
execute immediate 'grant execute on test_aq to maj_com';
l_reg_info_list := sys.aq$_reg_info_list(sys.aq$_reg_info('COM_OWNER.TEST_QUEUE', DBMS_AQ.NAMESPACE_AQ, 'plsql://COM_OWNER.TEST_AQ.GETMESSAGE?PR=0', hextoraw('FF')));
dbms_aq.register(l_reg_info_list, 1);
end ;
Following scripts was run from a user schema (FBOUCHER). This user has MAJ_COM role.
declare
msg RAW(500) ;
enq_opts dbms_aq.enqueue_options_t ;
msg_props dbms_aq.message_properties_t ;
begin
dbms_aq.enqueue(queue_name => 'COM_OWNER.TEST_QUEUE', enqueue_options => enq_opts, message_properties => msg_props, payload => hextoraw('FF'), msgid => msg) ;
commit ;
end ;

No. LabVIEW is available for Windows, Mac, Sun, and Linux. Every binary is unique to the OS. You can try to convince NI to create a LabVIEW version for VX Works but I don't think you'll get very far. Sorry.
