Parameters in a DB cluster parameter group apply to all of the instances in a DB cluster.
A DB cluster parameter group is initially created with the default parameters for the database engine used by instances in the DB cluster. To provide custom values for any of the parameters, you must modify the group after creating it using ModifyDBClusterParameterGroup. Once you've created a DB cluster parameter group, you need to associate it with your DB cluster using ModifyDBCluster. When you associate a new DB cluster parameter group with a running DB cluster, you need to reboot the DB instances in the DB cluster without failover for the new DB cluster parameter group and associated settings to take effect.
After you create a DB cluster parameter group, you should wait at least 5 minutes
before creating your first DB cluster that uses that DB cluster parameter group as
the default parameter group. This allows Amazon RDS to fully complete the create action
before the DB cluster parameter group is used as the default for a new DB cluster.
This is especially important for parameters that are critical when creating the default
database for a DB cluster, such as the character set for the default database defined
by the character_set_database
parameter. You can use the Parameter
Groups option of the Amazon RDS
console or the DescribeDBClusterParameters command to verify that your
DB cluster parameter group has been created or modified.
