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 Database Proxy Kernel Version Description.

A kernel version can be upgraded in either of the following ways:

To apply for the required permissions to upgrade the proxy instance version, choose Service Tickets > Create Service Ticket in the upper right corner of the management console and submit an application.

Precautions

  • Intermittent disconnections occur during the upgrade. The time required to complete the upgrade depends on how many proxy instances there are. Perform the upgrade during off-peak hours.
  • Only DB instances using the cluster HA type support proxy version upgrades. Contact customer service to check whether the HA type is cluster.

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 and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service. The RDS console is displayed.
  4. On the Instance Management page, click the target DB instance.
  5. On the Database Proxy page, in the Proxy Instance Information area, click Upgrade in the Version field.

  6. In the displayed dialog box, select a scheduled time and click OK.

    Figure 2 Selecting a scheduled time
    • Upon submission: The system upgrades the proxy instance to the latest version immediately after you submit the request. You can view the task progress in Task Center > Instant Tasks.
    • In maintenance window: The system upgrades the proxy instance to the latest version during a maintenance window. You can view the task progress in Task Center > Scheduled Tasks.
