Viewing Basic Cluster Information and Modifying Cluster Configurations

Scenario

After creating a CDM cluster, you can view its basic information and modify its configurations.

• You can view the following basic cluster information:
  • Cluster information: cluster version, creation time, project ID, instance ID, and cluster ID
  • Instance configuration: cluster flavor, CPU, and memory
  • Network configuration
• You can modify the following cluster configurations:
  • Notification: If a CDM migration job (only table/file migration) fails or the EIP is abnormal, CDM sends an SMS or email notification to the user.
  • User isolation: determines whether other users can operate the migration jobs or links in the cluster.
    • If this function is enabled, migration jobs and links in the cluster are isolated. Other IAM users of the a cloud platform account cannot operate the jobs and links.
    • If this function is disabled, migration jobs and links in the cluster can be shared by users. All IAM users with the required permission in the a cloud platform account can view and perform operations on the jobs and links in the cluster.

      After disabling User Isolation, restart the cluster VM for the settings to take effect.
