Modifying the Failover Priority

Scenarios

You can modify the failover priority with the priority on availability or reliability to meet service requirements.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click Relational Database Service to go to the RDS console.
  4. On the Instance Management page, locate the target primary/standby DB instance and click the DB instance name.
  5. On the displayed Basic Information page, click Change in the Failover Priority field. In the displayed dialog box, select a priority and click OK.

    • Reliability: This option is selected by default. Data consistency is preferentially ensured during the primary/standby switchover. This is recommended for users whose highest priority is data consistency.
    • Availability: Database availability is preferentially ensured during the primary/standby switchover. This is recommended for users who require their databases to provide uninterrupted online services.

  6. View the result of the change on the Basic Information page.
