Create Queues in the Database

1. Create the queues

   Connect to the database as the ADMIN user and execute the following statements to give the account user the necessary permissions to use queues. Note: module 2, Task 9 provided details on how to connect to the database.

   grant execute on dbms_aq to account;
   grant execute on dbms_aqadm to account;
   grant execute on dbms_aqin to account;
   commit;

   Now connect as the account user and create the queues by executing these statements (replace [TNS-ENTRY] with your environment information). You can get the TNS Entries by executing SHOW TNS in the sql shell:

   connect account/Welcome1234##@[TNS-ENTRY];
   
   begin
       -- deposits
       dbms_aqadm.create_queue_table(
           queue_table        => 'deposits_qt',
           queue_payload_type => 'SYS.AQ$_JMS_TEXT_MESSAGE');
       dbms_aqadm.create_queue(
           queue_name         => 'deposits',
           queue_table        => 'deposits_qt');
       dbms_aqadm.start_queue(
           queue_name         => 'deposits');
       -- clearances 
       dbms_aqadm.create_queue_table(
           queue_table        => 'clearances_qt',
           queue_payload_type => 'SYS.AQ$_JMS_TEXT_MESSAGE');
       dbms_aqadm.create_queue(
           queue_name         => 'clearances',
           queue_table        => 'clearances_qt');
       dbms_aqadm.start_queue(
           queue_name         => 'clearances');
   end;
   /

   You have created two queues named deposits and clearances. Both of them use the JMS TextMessage format for the payload.
