Correcting an ORA-24033 Error While Enqueuing Messages

If there are no consumers for a message when a user or application tries to enqueue it, then Oracle Database returns the following error:

ORA-24033: no recipients for message

The message is not enqueued when Oracle Database returns this message.

To correct the problem: 

1. Configure at least one consumer for the messages.

2. Enqueue the messages.

Consumers can be:

• Applications or users that dequeue and process messages

• Propagations that send messages from one queue to another

• Apply processes that can dequeue messages for custom processes in a messaging environment or dequeue changes to database objects in a replication environment

• Messaging clients that dequeue messages and pass them to an application
