After you create an ApsaraDB MyBase dedicated cluster, you can view, modify, and delete it.

Background information

For more information about an ApsaraDB MyBase dedicated cluster, see What is an ApsaraDB MyBase dedicated cluster?.

View ApsaraDB MyBase dedicated cluster information

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select the target region.
  3. On the Dedicated Clusters page, view the dedicated cluster information or download the information.
    • By default, the list displays information such as Dedicated Cluster ID, VPC, and Hosts. You can click the Settings icon on the right to customize the columns displayed in the list. In the Column Settings dialog box that appears, you can configure additional columns such as Cluster Type, Database Engine, Instance Allocation Policy, and Fault Handling Policy. Use the arrow buttons to move columns between Hidden Columns and Displayed Columns, and then click OK.
    • You can click the Download icon on the right to download the dedicated cluster information.
  4. In the Actions column of the target dedicated cluster, click Details.
  5. On the Basic Information page of the dedicated cluster, view its parameters.
    The following table describes the parameters.
    Parameter Description
    Dedicated Cluster ID/Name The ID and name of the dedicated cluster.
    VPC The VPC to which the dedicated cluster belongs.
    Hosts The number of hosts in the dedicated cluster.
    Instances The number of instances in the dedicated cluster.
    Resource Allocation Policy The default resource allocation policy for the dedicated cluster.
    • Balanced Allocation: Maximizes system stability by preferentially allocating resources from hosts with fewer or no allocated resources.
    • Compact Allocation: Maximizes resource utilization by preferentially allocating resources from hosts that already have allocated resources.
    CPU Overcommit Ratio The CPU overcommitment ratio of the dedicated cluster. For example, a ratio of 200% allows the total CPU resources of all instances to be twice the actual CPU resources, maximizing CPU resource usage.
    Storage Overcommit Ratio The storage overcommitment ratio of the dedicated cluster. For example, a ratio of 200% allows the total storage resources of all instances to be twice the actual storage resources, maximizing storage resource usage.
    Maximum Memory Usage The maximum memory usage for each host in the dedicated cluster. The value can range from 0% to 100%.
    Creation Time The time the dedicated cluster was created.

Modify an ApsaraDB MyBase dedicated cluster

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select the target region.
  3. On the Cluster List page, find the target dedicated cluster, and in the Actions column, click Modify.
  4. Configure the following parameters.
    The parameters include Dedicated Cluster Name, CPU Overcommitment Ratio (100% to 300%), Storage Overcommitment Ratio (100% to 200%), Maximum Memory Usage (0% to 100%), Resource Allocation Policy (options: even distribution or compact distribution), and Grant OS Permissions (options: Enable or Disable). After you complete the configuration, click OK.
    Parameter Description
    Dedicated Cluster Name A custom name for the dedicated cluster.
    CPU Overcommit Ratio The CPU overcommitment ratio of the dedicated cluster. Valid values: 100% to 300%. Default value: 200%. A ratio of 200% allows the total CPU resources of all instances to be twice the actual CPU resources, maximizing CPU resource usage.
    Storage Overcommit Ratio The storage overcommitment ratio of the dedicated cluster. Valid values: 100% to 200%. Default value: 200%. A ratio of 200% allows the total storage resources of all instances to be twice the actual storage resources, maximizing storage resource usage.
    Maximum Memory Usage The maximum memory usage for each host in the dedicated cluster. Valid values: 0% to 100%.
    Resource Allocation Policy The default resource allocation policy for the dedicated cluster.
    • Balanced Allocation: Maximizes system stability by preferentially allocating resources from hosts with fewer or no allocated resources.
    • Compact Allocation: Maximizes resource utilization by preferentially allocating resources from hosts that already have allocated resources.
    Grant OS Permissions Specifies whether to grant OS permissions. This option is unavailable for hosts that run the Redis engine.
    Note You cannot modify the VPC. To change the VPC, you must create a new dedicated cluster. For more information, see Create a cluster.
  5. Click OK.

Delete an ApsaraDB MyBase dedicated cluster

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select the target region.
  3. On the Cluster List page, find the target dedicated cluster, and in the Actions column, click Delete.
    Note You can delete a dedicated cluster only after all hosts and instances within it have been deleted.
  4. In the confirmation dialog box, click OK.
