Upgrading the Kernel Version of Database Proxy

Scenarios

You can manually upgrade the RDS for MySQL database proxy to the latest kernel version to improve performance, add new functions, and fix problems.

For details about kernel versions, see Kernel Versions.

Precautions

  • Intermittent disconnections occur during the upgrade. The time required to complete the upgrade depends on how many proxy nodes there are. Perform the upgrade during off-peak hours.
  • During the upgrade, short connections are not affected. Persistent connections lasting for more than 24 hours will be interrupted intermittently.

Constraints

  • Only proxy instances with kernel version 2.3.0.1 or later can be upgraded manually on the console.
  • A version upgrade cannot be rolled back after the upgrade is complete.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner of the page and choose Databases > Relational Database Service.
  3. On the Instances page, click the target DB instance.
  4. On the Database Proxy page, in the proxy information area, click Upgrade next to the Version field.
  5. In the displayed dialog box, select a scheduled time and click OK.
