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 guides you on 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 to share.
Cluster
- Log in to the DDS console.
- In the navigation pane on the left, click Parameter Group Management.
- On the Parameter Group Management page, click Create Parameter Group.
- Select a DB engine version from the DB Engine Version drop-down list, Cluster for DB Instance Type, specify 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: >!<"&'=
- On the Parameter Group Management page, view and manage parameter groups on the Clusters tab.
Replica Set
- Log in to the DDS console.
- In the navigation pane on the left, click Parameter Group Management.
- On the Parameter Group Management page, click Create Parameter Group.
- Select a DB engine version from the DB Engine Version drop-down list, Replica set for DB Instance Type, specify Parameter Group Name and Description, and then click OK.
- 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: >!<"&'=
- On the Parameter Group Management page, view and manage parameter groups on the Replica Sets tab.
