Note: Data queues are persistent objects, but their data content can be lost or corrupted during a system failure. Backup, recovery and maintenance of data queues used in your LANSA Composer solution is your responsibility – you should make provision for this in your implementation plans. |

Note | : Unlike many other iterator activities, this activity will iterate indefinitely unless you take specific action in the iterator block to exit the iteration.

For more information refer to Considerations for Extended Duration Processing Sequences . |
