Deleting an MQTT Connection Alias
Before you delete an MQTT connection alias, make sure of the following:
The MQTT connection alias is disabled.
A service that publishes MQTT messages does not rely on the MQTT connection alias.
An MQTT trigger does not use the MQTT connection alias to connect to the MQTT server and retrieve message.
While you can delete an MQTT connection alias that is in use, it may result in error or failures in MQTT triggers and MQTT message publishing services.
To delete an MQTT connection alias
1. Open Integration Server Administrator.
2. In the Settings menu of the Navigation panel, click Messaging.
3. Under MQTT Configuration, click MQTT Settings.
4. In the MQTT Connection Alias Definitions list, disable the alias if it is not already disabled.
5. Click 
in the Delete column for the alias. If an MQTT trigger uses the MQTT connection alias, Integration Server prompts you to confirm deleting the alias.
