You can manually release pay-as-you-go clusters based on your business requirements. The pay-as-you-go clusters are charged on an hourly basis. This topic describes how to manually release PolarDB for Oracle clusters.

Precautions

  • You cannot manually release subscription clusters.
    Note For more information about how to handle subscription and pay-as-you-go clusters after they expire or are overdue, see Cluster expiration and overdue payments.
  • You can manually release clusters whose Status is Running.
  • You can use this feature to release clusters. If this feature is used, all the nodes of the clusters are released. For more information about how to release a single read-only node, see Add or remove a read-only node.

Procedure

  1. Log on to the PolarDB console.
  2. In the upper-left corner of the console, select the region in which the cluster that you want to manage is deployed.
  3. On the Clusters page, find the cluster that you want to release and choose More > Release in the Actions column.

    Retain Backups value Description
    Permanently Retain All Backups Retains all the backups for a cluster when you delete the cluster.
    Permanently Retain Last Automatic Backup Retains the last backup for a cluster when you delete the cluster.
    Immediately Delete All Backups Deletes all the backups for a cluster when you delete the cluster.
    Warning If you select this policy, the deleted clusters cannot be restored.
    Note
    • If you select the Permanently Retain All Backups or Permanently Retain Last Automatic Backup policy, the system runs an automatic backup task to retain all the data about a cluster when you delete the PolarDB cluster.
    • After you delete a cluster, level-1 backups are automatically transferred to level-2 backups. You can go to the Cluster Recycle page to view all backups. For more information, see Restore a released cluster.
