ModifyDBParameterGroup
Modifies the parameters of a DB parameter group. To modify more than one parameter,
submit a list of the following: ParameterName
, ParameterValue
, and
ApplyMethod
. A maximum of 20 parameters can be modified in a single request.
Note
Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB instance associated with the parameter group before the change can take effect.
Important
After you modify a DB parameter group, you should wait at least 5 minutes before
creating your first DB instance that uses that DB parameter group as the default parameter
group. This allows Amazon Neptune to fully complete the modify action before the parameter
group is used as the default for a new DB instance. This is especially important for
parameters that are critical when creating the default database for a DB instance, 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 Neptune console or the
DescribeDBParameters command to verify that your DB parameter group has
been created or modified.
