Notes and Constraints
- To ensure that the instance runs properly, do not perform other operations on the instance during the modification.
- The price may change after the modification.
Prerequisites
A RabbitMQ instance has been created and is in the Running state.
Modifying RabbitMQ Instance Specifications
- Log in to the console.
- In the upper left corner, click
and select a region.
NOTE:
Select the region where your RabbitMQ instance is.
- Click
and choose Middleware > Distributed Message Service for RabbitMQ to open the console of DMS for RabbitMQ.
- 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.
- Specify the required storage space, number of brokers, or bandwidth.
- Expand the storage space.
- RabbitMQ 3.x.x: For Modify By, select Storage. For Storage Space per Broker, specify a new storage space.
View the new storage space (Total storage space = Storage space per broker x Number of brokers) in the Used/Available Storage Space (GB) column in the instance list.
- RabbitMQ AMQP-0-9-1: For Modify By, select Storage. For Storage, specify a new storage space.
View the new storage space in the Used/Available Storage Space (GB) column in the instance list.
NOTE:
- Available storage space = Actual storage space – Storage space for storing logs – Disk formatting loss For example, if the storage space is expanded to 700 GB, the storage space for storing logs is 100 GB, and the disk formatting loss is 7 GB, then the available storage space after capacity expansion will be 593 GB.
- Storage space expansion does not affect services.
- RabbitMQ 3.x.x: For Modify By, select Storage. For Storage Space per Broker, specify a new storage space.
- Add brokers.
For Modify By, select Brokers. Then, enter the number of brokers.
View the number of brokers in the Specifications column in the instance list.
NOTE:
- Services may temporarily stutter during the modification. Ensure that your client can auto-reconnect. Modify specifications during off-peak hours.
- Brokers cannot be increased for RabbitMQ AMQP-0-9-1.
- Increase or decrease the broker flavor.
- RabbitMQ 3.x.x: For Modify By, select Broker Flavor. Then, select a new flavor.
View the broker flavor in the Flavor column of the instance list.
- RabbitMQ AMQP-0-9-1: For Modify By, select Instance Flavor. Then, select a new flavor.
View the new flavor in the Flavor column of the instance list.
NOTE:
- RabbitMQ 3.x.x: For cluster instances without mirrored/quorum queues configured and single-node instances, services may stutter for several minutes during the modification. Ensure that your client can auto-reconnect. Modify specifications during off-peak hours.
- RabbitMQ 3.x.x: For cluster instances configured with mirrored/quorum queues, services may stutter for several seconds during the modification. Ensure that your client can auto-reconnect. Modify specifications during off-peak hours.
- RabbitMQ AMQP-0-9-1: For single-node and cluster instances, intermittent disconnections may occur for several seconds during the modification. Ensure that your client can auto-reconnect. Modify specifications during off-peak hours.
- RabbitMQ 3.x.x: For Modify By, select Broker Flavor. Then, select a new flavor.
- Expand the storage space.
- Click Next, confirm the details, and click Submit.
