Replicating a Parameter Group

Scenarios

You can replicate a parameter group you have created. When you have already created a parameter group and want to include most of the custom parameters and values from that group in a new parameter group, you can replicate that parameter group. You can also export the parameter group to generate a parameter group for future use.

After replicating a parameter group, you should wait at least 5 minutes before creating your first DB instance that uses the parameter group as the default parameter group.

You cannot replicate default parameter groups but you can create new parameter groups based on the default parameter groups.

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 Database, click Relational Database Service to go to the RDS console.
  4. Choose Parameter Group Management in the navigation pane on the left. On the Custom Groups page, locate the parameter group to be replicated and click Replicate in the Operation column.

    Alternatively, click the target DB instance on the Instance Management page. On the Parameters page, click Export to generate a new parameter group for future use.

  5. In the displayed dialog box, specify New Parameter Group and Description, and click OK.

    • The group name must consist of 1 to 64 characters. It can contain only uppercase letters, lowercase letters, digits, hyphens (-), underscores (_), and periods (.).
    • The description must consist of a maximum of 256 characters and cannot contain the carriage return character or the following special characters: >!<"&'=

    After the new parameter group is created, you can manage it in the parameter group list.
