Applying a Parameter Template

Modifications to parameters in a custom parameter template take effect for DB instances only after you have applied the template to the DB instances.

Log in to the management console.
Click in the upper left corner and select a region and a project.
Click in the upper left corner of the page and choose Databases > Document Database Service.
In the navigation pane on the left, choose Parameter Templates.
On the Parameter Templates page, apply a default template or a custom template to the DB instance:
- To apply a default template, click the Default Templates tab, locate the required parameter template, and click Apply in the Operation column.
- To apply a custom template, click Custom Templates, locate the parameter template, and in the Operation column, choose More > Apply.
A parameter template can be applied to one or more nodes and instances.
In the displayed dialog box, select the node or instance to which the parameter template will be applied and click OK.

After the parameter template is successfully applied, you can view the application records by referring to Viewing Application Records of a Parameter Template.
