Question

Answer 1

I have copied your code here and commented it inline.
1.Logged in as sysdba
create user aquser identified by password;
GRANT CONNECT, RESOURCE to aquser;
-- Never grant connect or resource. These are demo roles and the definition changes in different versions.
-- The connect role should be replaced with GRANT CREATE SESSION.
GRANT EXECUTE ON SYS.DBMS_AQ to aquser;
GRANT EXECUTE ON SYS.DBMS_AQADM to aquser;
GRANT EXECUTE ON SYS.DBMS_AQIN to aquser;
commit;
-- commit is unnecessary and with DCL does nothing as DCL contains two implicit commits.
I have also given him dba privileges
-- why? this is a breach of essentially all reasonable security protocols. Revoke this and provide only the minimum
-- explicit system privileges required to perform the user function. The required privs are described in detail in the
-- Oracle docs and also on my website in the demo I provided to you previously.
-- http://www.morganslibrary.org/reference/aq_demo1.html
2. Then i created the type(logged in as aquser)
create or replace type customer_type as object
name varchar2(100),
location varchar2(50),
contract CLOB
The type is created.
3.Then i tried to create the queue
begin
dbms_aqadm.create_queue_table('customer_in_table', 'aquser.customer_type');
-- your table name will be CUSTOMER_IN_TABLE
-- your payload type is CUSTOMER_TYPE
-- and you did not provide any values for the remaining 11 parameters.
dbms_aqadm.create_queue('customer_in_queue', 'customer_in_table');
-- your queue name is CUSTOMER_IN_QUEUE
-- your table_name is the same as created previously
-- and you did not provide any values for the remaining 7 parameters.
dbms_aqadm.start_queue('customer_in_queue');
end;From this I see no possibility that you received the exception you posted so something you did does not correspond with what you posted.
Here is the error message you posted:
cannot create QUEUE_TABLE, user ANONYMOUS does not have execute privileges on QUEUE_PAYLOAD_TYPE ANDY.STREET_INFOThe user AQUSER is not the user ANONYMOUS.
