dbParameterGroupName

The name of the DB parameter group to associate with this read replica DB instance.

For the Db2 DB engine, if your source DB instance uses the Bring Your Own License model, then a custom parameter group must be associated with the replica. For a same Amazon Web Services Region replica, if you don't specify a custom parameter group, Amazon RDS associates the custom parameter group associated with the source DB instance. For a cross-Region replica, you must specify a custom parameter group. This custom parameter group must include your IBM Site ID and IBM Customer ID. For more information, see IBM IDs for Bring Your Own License for Db2.

For Single-AZ or Multi-AZ DB instance read replica instances, if you don't specify a value for DBParameterGroupName, then Amazon RDS uses the DBParameterGroup of the source DB instance for a same Region read replica, or the default DBParameterGroup for the specified DB engine for a cross-Region read replica.

For Multi-AZ DB cluster same Region read replica instances, if you don't specify a value for DBParameterGroupName, then Amazon RDS uses the default DBParameterGroup.

Specifying a parameter group for this operation is only supported for MySQL DB instances for cross-Region read replicas, for Multi-AZ DB cluster read replica instances, for Db2 DB instances, and for Oracle DB instances. It isn't supported for MySQL DB instances for same Region read replicas or for RDS Custom.

• Must be 1 to 255 letters, numbers, or hyphens.
