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

Background

For more information about ApsaraDB for MyBase, see What is ApsaraDB for MyBase.

View cluster information

  1. Log on to the ApsaraDB for MyBase console.
  2. In the upper-left corner of the page, select the target region.
  3. On the Dedicated Clusters page, you can view and download your cluster information.
    • By default, information such as Dedicated Cluster ID, VPC, and Hosts is displayed. You can click the Settings icon on the right to customize the columns in the list.
    • You can click the Download icon on the right to download the cluster information to your computer.
  4. Find the target cluster and click Details in the Actions column.
  5. On the Dedicated cluster information page, view the parameters.
    Parameter Description
    Dedicated cluster ID The ID of the dedicated cluster.
    Dedicated cluster name The name of the dedicated cluster.
    Engine The engine of the dedicated cluster.
    Architecture series

    This parameter is available only when the engine is MySQL. The default value is High-availability Edition.
    VPC The VPC where the cluster resides.
    Hosts The number of hosts in the dedicated cluster.
    Instances The number of instances in the dedicated cluster.
    Host Troubleshooting Policy The policy for handling host failures. Valid values:
    • Automatic host replacement: The system automatically replaces a faulty host.
      Note
      • If the faulty host uses cloud disks, its computing resources are automatically migrated to replace the host.
      • If the faulty host does not use cloud disks, the system first migrates the instances from the faulty host and then automatically replaces it.
    • Manual host replacement: You must manually replace a faulty host.
    Grant OS permissions Indicates whether OS permissions are granted for the hosts.
    Resource allocation policy The default resource allocation policy for the dedicated cluster. Valid values:
    • Balanced Allocation: Prioritizes system stability. Resources are preferentially allocated from hosts that have no or few allocated resources.
    • Compact Allocation: Prioritizes resource utilization. Resources are preferentially allocated from hosts that were created earlier and have more allocated resources.
    CPU Overcommit Ratio For example, a ratio of 200% means that the sum of CPU resources for all instances can be twice the actual physical CPU resources. This helps maximize CPU resource utilization.
    Storage Overcommit Ratio For example, a ratio of 200% means that the sum of storage resources for all instances can be twice the actual physical storage resources. This helps maximize storage utilization.
    Maximum Memory Usage The maximum memory allocation rate for each host in the dedicated cluster.
    Creation Time The time when the cluster was created.

Edit a cluster

  1. Log on to the ApsaraDB for MyBase console.
  2. In the upper-left corner of the page, select the target region.
  3. In the left-side navigation pane, click Dedicated Clusters.
  4. On the Dedicated Clusters page, find the target cluster and click Edit in the Actions column.
  5. Configure the following parameters.
    The configurable parameters include Dedicated cluster name, CPU overcommit ratio (100% to 300%), Storage overcommit ratio (100% to 200%), Maximum memory allocation rate (0% to 100%), Resource allocation policy (select Balanced Allocation or Compact Allocation), Host troubleshooting policy (select Automatic Host Replacement or Manual Host Replacement), and Grant OS permissions (select Grant or Do not grant). Then, click OK.
    Parameter Description
    Dedicated cluster name A custom name for the cluster for easy identification.
    CPU Overcommit Ratio The CPU overcommit ratio of the dedicated cluster.
    Note The valid values and default value for this parameter vary by engine. For more information, see the information provided in the console.
    Storage Overcommit Ratio The storage overcommit ratio of the dedicated cluster. You can modify this parameter only for MySQL clusters.
    Note The valid values and default value for this parameter vary by engine. For more information, see the information provided in the console.
    Maximum Memory Usage The maximum memory allocation rate for each host in the dedicated cluster.
    Note The valid values and default value for this parameter vary by engine. For more information, see the information provided in the console.
    Resource Allocation Policy The default resource allocation policy for the dedicated cluster. Valid values:
    • Balanced Allocation: Prioritizes system stability. Resources are preferentially allocated from hosts that have no or few allocated resources.
    • Compact Allocation: Prioritizes resource utilization. Resources are preferentially allocated from hosts that were created earlier and have more allocated resources.
    Host Troubleshooting Policy The policy for handling host failures. Valid values:
    • Automatic host replacement: The system automatically replaces a faulty host.
      Note
      • If the faulty host uses cloud disks, its computing resources are automatically migrated to replace the host.
      • If the faulty host does not use cloud disks, the system first migrates the instances from the faulty host and then automatically replaces it.
    • Manual host replacement: You must manually replace a faulty host.
    Grant OS Permissions Grants OS-level access to hosts in a cluster running MySQL, SQL Server, or PostgreSQL. This access allows you to log on to hosts to manage files and install software.
    Important OS permissions cannot be revoked after they are granted.
  6. Click OK.
