Rebooting a DB Instance


You can reboot a DB instance for the modifications to take effect.

  • You can reboot a DB instance only when its status is Available. Your database may be unavailable in some cases, for example, when some modifications are being made.
  • Rebooting a DB instance will cause service interruptions. During this period, the DB instance status is Rebooting.
  • An instance is not available when it is being rebooted. After the reboot completes, the cached memory will be automatically cleared. You are advised to reboot the instance during off-peak hours.
  • To quickly reboot a DB instance, perform fewer operations on the DB instance.
  • If there are a large number of slow SQL statements or sessions, or if the thread pool is full, the reboot process may take a longer time than usual.
