Creating a Parameter Group

Scenarios

DB parameter groups act as a container for engine configuration values that are applied to one or more DB instances. This section describes how to create a parameter group to manage your DB instance configurations.

  • DDS does not share parameter group quotas with RDS.
  • Each account can create up to 100 DDS parameter groups for the cluster and replica set instances.

Cluster

  1. Log in to the DDS console.
  2. In the navigation pane on the left, click Parameter Group Management.
  3. On the Parameter Group Management page, click Create Parameter Group.
  4. Specify DB Engine Version, DB Instance Type, Node Type, Parameter Group Name, and Description and then click OK.

    • Node Type: specifies the node type that this parameter group will apply to. For example, to create a parameter group applying to config, select config.
    • Parameter Group Name: specifies the parameter group name, which is a string of 1 to 64 characters composed of only letters (case-sensitive), digits, hyphens (-), underscores (_), and periods (.).
    • Description: contains a maximum of 256 characters and cannot contain the carriage return character and the following special characters: >!<"&'=

  5. On the Parameter Group Management page, view and manage parameter groups on the Clusters tab.

Replica Set

  1. Log in to the DDS console.
  2. In the navigation pane on the left, click Parameter Group Management.
  3. On the Parameter Group Management page, click Create Parameter Group.
