Rebooting a GaussDB 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.

Log in to the management console.
Click in the upper left corner and select a region and project.
Click in the upper left corner of the page and choose Databases > GaussDB.
On the Instances page, locate the instance you want to reboot and choose More > Reboot in the Operation column.

Alternatively, click the instance name to go to the Basic Information page. Click Reboot in the upper right corner of the page.
