Modifying Cluster Configurations

Configuration Description

After a CDM cluster is created, you can modify the following configurations:
  • Auto Shutdown

    If no job is running in the cluster and no scheduled job is configured, the CDM cluster automatically shuts down after 15 minutes to avoid incurring any additional costs.

  • Scheduled Startup/Shutdown

    Scheduled startup/shutdown and auto shutdown cannot be enabled at the same time. You can configure scheduled startup/shutdown at a specific time every day. During scheduled shutdown, the system does not wait for unfinished jobs to complete.

  • 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. Up to five mobile numbers and five email addresses can be configured.

  • User Isolation
    • Enabled

      Migration jobs and links in the cluster are isolated. Other IAM users under the same cloud account cannot view the jobs and links.

    • Disabled

      Migration jobs and links in the cluster can be shared by users. All IAM users with CDM Administrator permissions under the same cloud account can view and perform operations on the jobs and links.After disabling User Isolation, restart the cluster VM for the settings to take effect.

Procedure

  1. Log in to the CDM management console.
  2. In the left navigation pane, click Cluster Management. The Cluster Management page is displayed.
  3. Click the name of a cluster and click the Cluster Configuration tab to modify the configuration of auto shutdown, scheduled startup/shutdown, notification, or user isolation.
