Consuming Job State Events with your Application
To consume job state events, your application must subscribe to the Scheduler event queue SYS.SCHEDULER$_EVENT_QUEUE. This queue is a secure queue and is owned by SYS. To create a subscription to this queue for a user, do the following:
1. Log in to the database as the SYS user or as a user with the MANAGE ANY QUEUE privilege.
2. Subscribe to the queue using a new or existing agent.
3. Run the package procedure DBMS_AQADM.ENABLE_DB_ACCESS as follows:
DBMS_AQADM.ENABLE_DB_ACCESS(agent_name, db_username); where agent_name references the agent that you used to subscribe to the events queue, and db_username is the user for whom you want to create a subscription.
There is no need to grant dequeue privileges to the user. The dequeue privilege is granted on the Scheduler event queue to PUBLIC.
