Removing a queue

To remove an MER queue you must remove the CO for the queue from the OU. Furthermore, it is possible that role definitions and MER routing are based on this queue and they must be changed as well.

Queues must be empty before they are removed. Before removing a queue from the configuration, make sure that there are no messages on the main queue or any of its associated queues, for example the backout queue. Remaining messages must be processed, or moved to another queue by a message administrator. If possible, deploy adapted MER Routing message flows before removing a queue, to ensure that the queue remains empty until you delete it. Otherwise, you must prevent routing of messages to that queue by some other means, and deploy adapted message flows immediately after removing the queue.

Use the following CLI command to remove a queue from an OU. You must have the system configuration administrator (DniSA) role:

dnicli -i instance -ou SYSOU -s DNI_SYSADM
rem -ou ou -ct DnqERQueue -co queue

You must commit, approve, and deploy the OU.

After you remove an existing queue and the related role definitions:

Restart the MER enterprise application in the application server to make the changes visible.
Deploy adapted MER Routing message flows to ensure that no more message are routed to the deleted queue. This step can be skipped if the adapted message flows were deployed before the queue was removed.
