In the dialog box, use the left and right arrow buttons to move columns between Hidden Columns and Displayed Columns. The configurable columns include Dedicated Cluster ID/Name, Cluster Type, VPC, Database Engine, Instance Allocation Policy, and Host Troubleshooting Policy. After you complete the configuration, click OK.

    • 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:

    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:

    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:

    Host Troubleshooting Policy

    The policy for handling host failures. Valid values:

    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.
