Applying a Parameter Template

Scenarios

Modifications to parameters in a custom parameter template take effect only after you apply this parameter template to target DB instances.

• The parameter innodb_buffer_pool_size is determined by the memory. DB instances of different specifications have different value ranges. If this parameter value is out of range of the DB instance to which the parameter template applies, the maximum value within the range is used.
• A parameter template can be applied only to DB instances of the same DB engine version.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Databases, click GaussDB(for MySQL).
4. On the Parameter Templates page, you can apply a default template or a custom template to a target DB instance:
   • To apply a default template, click Default Templates, locate the target parameter template, and in the Operation column, click Apply.
   • To apply a custom template, click Custom Templates, locate the target parameter template, and in the Operation column, choose More > Apply.

   A parameter template can be applied to one or more DB instances.

5. In the displayed dialog box, select one or more DB instances to which the parameter template will apply and click OK.

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