Modifying Instance Specifications

Scenario

After creating a RabbitMQ instance in cluster mode, you can modify the number of cluster brokers, but cannot modify the specifications themselves. This operation is not supported by RabbitMQ instances in single-node mode.

• To ensure that the instance runs properly, do not perform other operations on the instance during the modification.
• During the specification modification, the LVS node is restarted and the client is disconnected. The service code must be able to handle this situation to prevent service interruption.

Prerequisites

A RabbitMQ instance has been created and is in the Running state.

Procedure

1. Log in to the management console.
2. In the upper left corner, click and select a region.
   

   Select the same region as your application service.

3. Click and choose Application > Distributed Message Service for RabbitMQ to open the console of DMS for RabbitMQ.
4. In the row containing the instance for which you want to modify the specifications, choose More > Modify Specifications in the Operation column.
5. Specify the desired number of cluster nodes and click Submit.

   View the number of cluster nodes on the RabbitMQ Premium page.
