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

Background information

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

View information about dedicated clusters

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select a region.
  3. On the Clusters page, you can view information about your dedicated clusters. You can also download the information to an on-premises machine.
    • On the Dedicated Clusters page, Dedicated Cluster ID, VPC, Hosts, and other columns are displayed in the table that contains information about your dedicated clusters by default. You can click the Custom Columns icon Custom Columns icon in the upper-right corner of the page to specify the columns that you want the system to display in the table. Specify columns to be displayed
    • You can click the Export Resources icon Download icon next to the Custom Columns icon to download information about your dedicated clusters to your on-premises machine.
  4. Find the dedicated cluster and click Details in the Actions column.
  5. On the page that appears, view information about the dedicated cluster.
    Parameter Description
    Dedicated Cluster ID The ID of the dedicated cluster.
    Dedicated Cluster Name The name of the dedicated cluster.
    Engine The database engine that the dedicated cluster runs.
    Architecture

    The edition of the dedicated cluster. This parameter is displayed only if the dedicated cluster is an ApsaraDB MyBase for MySQL dedicated cluster. The default value of the parameter is High-availability/Master-replica Edition.

    VPC The VPC in which the dedicated cluster is deployed.
    Hosts The number of hosts in the dedicated cluster.
    Instances The number of instances in the dedicated cluster.
    Host Troubleshooting Policy The policy based on which the system handles host failures. Valid values:
    • Automatic Host Replacement: The system automatically replaces the faulty hosts.
      Note
      • If a faulty host uses ESSDs, the host is replaced after the computing resources on the host are migrated.
      • If a faulty host uses local SSDs, the host is replaced only after all instances are removed from the host.
    • Manual Host Replacement: You must manually replace the faulty hosts.
    Grant OS Permissions Indicates whether the OS management feature is enabled for hosts in the dedicated cluster.
    Resource Allocation Policy The policy based on which the system allocates resources in the dedicated cluster. Valid values:
    • Balanced Allocation: New database instances are preferentially created on hosts that have the most available resources to maximize cluster stability.
    • Compact Allocation: New database instances are preferentially created on hosts that have been created earlier and have more resources allocated. This maximizes resource usage.
    CPU Overcommit Ratio The CPU overcommit ratio of the dedicated cluster. If the CPU overcommit ratio is 200%, the total number of CPU resources that the system can allocate to instances in the cluster is twice the number of CPU resources that you specify for the instances. This can help you maximize CPU utilization.
    Storage Overcommit Ratio The storage overcommit ratio of the dedicated cluster. If the storage overcommit ratio is 200%, the amount of storage space that the system can allocate to instances in the cluster is twice the amount of storage space that you specify for the instances. This can help you maximize storage usage.
    Maximum Memory Usage The maximum memory usage of each host in the dedicated cluster.
    Creation Time The point in time when the dedicated cluster was created.

Modify the configuration of a dedicated cluster

  1. Log on to the ApsaraDB MyBase console.
  2. In the upper-left corner of the page, select a region.
  3. On the Dedicated Clusters page, find the dedicated cluster that you want to modify and click Edit in the Actions column.
  4. Specify new values for parameters.
    Modify the configuration of a dedicated cluster
    Parameter Description
    Dedicated Cluster Name The name of the dedicated cluster. You can specify a name that can help you identify the cluster in a quick manner.
    CPU Overcommit Ratio The CPU overcommit ratio of the dedicated cluster.
    Note The default value and valid values of this parameter vary based on database engines. You can view the default value and valid values in the Edit Dedicated Cluster panel.
    Storage Overcommit Ratio The storage overcommit ratio of the dedicated cluster. You can change the value of this parameter only if the dedicated cluster is an ApsaraDB MyBase for MySQL dedicated cluster.
    Note The default value and valid values of this parameter vary based on database engines. You can view the default value and valid values in the Edit Dedicated Cluster panel.
    Maximum Memory Usage The maximum memory usage of each host in the dedicated cluster.
    Note The default value and valid values of this parameter vary based on database engines. You can view the default value and valid values in the Edit Dedicated Cluster panel.
    Resource Allocation Policy The policy based on which the system allocates resources to instances in the dedicated cluster. Valid values:
    • Balanced Allocation: New database instances are preferentially created on hosts that have the most available resources to maximize cluster stability.
    • Compact Allocation: New database instances are preferentially created on hosts that have been created earlier and have more resources allocated. This maximizes resource usage.
    Host Troubleshooting Policy The policy based on which the system handles host failures. Valid values:
    • Automatic Host Replacement: The system automatically replaces the faulty hosts.
      Note
      • If a faulty host uses ESSDs, the host is replaced after the computing resources on the host are migrated.
      • If a faulty host uses local SSDs, the host is replaced only after all instances are removed from the host.
    • Manual Host Replacement: You must manually replace the faulty hosts.
    Grant OS Permissions If you enable the OS management feature for a dedicated cluster that runs the MySQL, SQL Server, or PostgreSQL database engine, you can log on to the hosts in the dedicated cluster to upload files, download files, and install software.
    Notice After you enable this feature for the dedicated cluster, you cannot disable the feature.
  5. Click OK.
