Rebooting DB Instances or Read Replicas

Scenarios

You may need to reboot a DB instance during maintenance. For example, after you modify some parameters, a reboot is required for the modifications to take effect. You can reboot a primary DB instance or a read replica on the management console.

Constraints

• If the database service status is abnormal, you can forcibly reboot the DB instance, but this will interrupt uncommitted transactions.
• Rebooting DB instances will cause service interruptions. During the reboot process, the DB instance status is Rebooting.
• Rebooting DB instances will cause instance unavailability and clear cached memory. To prevent traffic congestion during peak hours, you are advised to reboot DB instances during off-peak hours.

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. The RDS console is displayed.
4. On the Instance Management page, locate the target DB instance, or click and then locate the target read replica. Choose More > Reboot in the Operation column.

   Alternatively, click the target DB instance on the Instance Management page to go to the Basic Information page. In the upper right corner, click Reboot.

   For primary/standby DB instances, if you reboot the primary DB instance, the standby DB instance is also rebooted automatically.

5. In the displayed dialog box, select a reboot mode. If you select Forceful, select the checkbox before Confirm forcible reboot and click Yes.
6. Refresh the DB instance list and view the status of the DB instance. If its status is Available, it has rebooted successfully.
