Prerequisites

Modifying RabbitMQ Instance Specifications

1. Log in to the console.
2. In the upper left corner, click and select a region.
3. Click and choose Application > Distributed Message Service for RabbitMQ to open the console of DMS for RabbitMQ.
4. Modify the instance specifications using either of the following methods:
   • In the row containing the desired instance, choose More > Modify Specifications.
   • Click the desired RabbitMQ instance to view its details. In the upper right corner, choose More > Modify Specifications.

5. Specify the required storage space, number of brokers, or bandwidth.
   • Expand the storage space.
     1. For Change By, select Storage. For Storage space per broker, specify a new storage space, and click Next. The storage space range varies by instance specifications. For details, see Specifications.
     2. Confirm the configurations and click Submit.
     3. Return to the instance list and check whether the change succeeded.
        • If the instance status has changed from Changing to Running, the change succeeded. View the new storage space (Storage space per broker x Number of brokers) in the Used/Available Storage Space (GB) column in the instance list.
        • If the instance status has changed from Changing to Change failed, the change failed. Move the cursor over Change failed to check the failure cause.

          Instances in the Change failed state cannot be modified, or deleted. After the instance status automatically changes from Change failed to Running, you can continue to perform operations. If the status does not change to Running, contact customer service.

   • Add brokers.
     1. For Modify By, select Brokers. Then, enter the number of brokers. The broker quantity range varies by instance specifications. For details, see Specifications. If public access has been enabled, configure EIPs for the new brokers. Then click Next.
     2. Confirm the configurations and click Submit.
     3. Return to the instance list and check whether the change succeeded.
        • If the instance status has changed from Changing to Running, the change succeeded. You can check the new broker quantity in the Flavor column.
        • If the instance status has changed from Changing to Change failed, the change failed. Move the cursor over Change failed to check the failure cause.

          Instances in the Change failed state cannot be modified, or deleted. After the instance status automatically changes from Change failed to Running, you can continue to perform operations. If the status does not change to Running, contact customer service.

   • Increase or decrease the broker flavor.
     1. For Modify By, select Broker Flavor. Then, select a new flavor and click Next.
     2. Confirm the configurations and click Submit.
     3. Return to the instance list and check whether the change succeeded.
        • If the instance status has changed from Changing to Running, the change succeeded. You can check the new broker flavor in the Flavor column.
        • If the instance status has changed from Changing to Change failed, the change failed. Move the cursor over Change failed to check the failure cause.

          Instances in the Change failed state cannot be modified, or deleted. After the instance status automatically changes from Change failed to Running, you can continue to perform operations. If the status does not change to Running, contact customer service.
