Specify cluster parameters

Procedure

1. Log on PolarDB console.
2. On the top of the page, select the region where the target cluster is located.
3. Find the target cluster and click the cluster ID to go to the Overview page.
4. In the left-side navigation pane, choose Settings and Management > Parameters.
5. Find the parameter for which you want to change the value, and click the icon in the Current Value column. In the dialog box that appears, enter the new value and click OK.
   

   Note

   • You must enter the parameter values that are included in the right-side Value Range column. Otherwise, an error message appears when you Apply Changes.
   • You can move your pointer over the icon of a parameter to view the parameter details.
6. In the left-right corner, click Apply Changes. In the Save Changes panel, click OK.
   

   Note

   • After you click Apply Changes for a parameter for which the value of Force Restart is Yes, you must restart all the nodes in the cluster to apply the changes. We recommend that you make appropriate service arrangements before you restart the nodes. Use caution if you need to restart the nodes.
   • If your cluster version is PolarDB for MySQL 8.0, you can specify the innodb_fast_startup parameter as ON to accelerate the restart process. For more information about how to change parameter values, see Specify cluster parameters.
