The DB-to-JMS mechanism has the following limitations:
- It is only used to put messages onto queues, not to take them off queues and process them.
- Messages can only be seen by the application server after the batch program transaction has been committed.
- The application server does not poll the table for messages, it must be notified to do so.
- It is not a JMS implementation i.e. it only works for specific IBM Cúram Social Program Management queues.
