Modifying Parameters in a Parameter Template
Function
This API is used to modify parameters in a specified parameter template, including parameter names, descriptions, and values. Before calling this API:
- Learn how to authorize and authenticate it.
- Obtain the required region and endpoint.
Constraints
- Default parameter templates cannot be modified.
- The name of the modified parameter template must be different from that of a default parameter template.
- The parameter values to be modified must be within the default value range of the specified database version.
Authorization Information
Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.
- If you are using role/policy-based authorization, see Permissions and Supported Actions for details on the required permissions.
- If you are using identity policy-based authorization, the following identity policy-based permissions are required.
