ApsaraDB RDS:Upgrade the database proxy kernel version

Usage notes

• When you upgrade the database proxy version of your RDS instance, new sessions are connected to the database proxy of the new version to reduce the impacts on your workloads.

  • Active sessions on the database proxy of the original version are retained for 8 hours. The database proxy of the original version is automatically disconnected within the first maintenance window.

  • When the database proxy of the original version is disconnected, existing connections on the database proxy are immediately terminated. Make sure that your application is configured to automatically reconnect to your database system.

• If you upgrade the database proxy version multiple times within a short period of time, the system retains only the sessions on the database proxy before the most recent upgrade.

• We recommend that you perform the upgrade during off-peak hours. Make sure that your application can automatically reconnect to your RDS instance.

Procedure

1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

2. In the left-side navigation pane, click Database Proxy.

3. In the Basic Information section, click Upgrade next to Proxy Version.

4. In the dialog box that appears, select an Update Time and click OK.

   Note

   • For Upgrade Now, you can select Upgrade Now or Within Maintenance Window. For more information about maintenance windows, see Set a maintenance window.

   • If you set Update Time to Within Maintenance Window and click OK, the RDS instance generates an upgrade plan based on the current maintenance window. The generated upgrade plan is not affected by subsequent changes to the maintenance window.
