Restarting an Instance

On the DCS console, you can restart one or multiple DCS instances at a time.

  • After a single-node DCS instance is restarted, data will be deleted from the instance.
  • While a DCS instance is restarting, it cannot be read or written.
  • An attempt to restart a DCS instance while it is being backed up may result in a failure.
  • Restarting a DCS instance will disconnect the original client. You are advised to configure automatic reconnection in your application.

Prerequisites

The DCS instances you want to restart are in the Running or Faulty state.

Procedure

  1. Log in to the DCS console.
  2. Click in the upper left corner of the management console and select the region where your instance is located.
  3. In the navigation pane, choose Cache Manager.
  4. On the Cache Manager page, select one or more DCS instances you want to restart.
  5. Click Restart above the DCS instance list.
  6. In the displayed dialog box, click Yes.

    It takes 10 seconds to 30 minutes to restart DCS instances. After DCS instances are restarted, their status changes to Running.

    • By default, only the instance process will be restarted. If you select Force restart for a DCS Redis 3.0 or Memcached instance, its VM will be restarted. Force restart is not supported by DCS Redis 4.0 or later instances.
    • To restart a single instance, you can also click Restart in the row containing the desired instance.
    • The time required for restarting a DCS instance depends on the cache size of the instance.
