ModifyDBCluster
Modify a setting for a DB cluster. You can change one or more database configuration parameters by specifying these parameters and the new values in the request.
Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
- AllowMajorVersionUpgrade
-
A value that indicates whether upgrades between different major versions are allowed.
Constraints: You must set the allow-major-version-upgrade flag when providing an
EngineVersion
parameter that uses a different major version than the DB cluster's current version.Type: Boolean
Required: No
- ApplyImmediately
-
A value that specifies whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the
PreferredMaintenanceWindow
setting for the DB cluster. If this parameter is set tofalse
, changes to the DB cluster are applied during the next maintenance window.The
ApplyImmediately
parameter only affectsNewDBClusterIdentifier
values. If you set theApplyImmediately
parameter value to false, then changes toNewDBClusterIdentifier
values are applied during the next maintenance window. All other changes are applied immediately, regardless of the value of theApplyImmediately
parameter.Default:
false
Type: Boolean
Required: No
- BackupRetentionPeriod
-
The number of days for which automated backups are retained. You must specify a minimum value of 1.
Default: 1
Constraints:
-
Must be a value from 1 to 35
Type: Integer
Required: No
-
- CloudwatchLogsExportConfiguration
-
The configuration setting for the log types to be enabled for export to CloudWatch Logs for a specific DB cluster. See Using the CLI to publish Neptune audit logs to CloudWatch Logs.
Type: CloudwatchLogsExportConfiguration object
Required: No
- CopyTagsToSnapshot
-
If set to
true
, tags are copied to any snapshot of the DB cluster that is created.Type: Boolean
Required: No
- DBClusterIdentifier
-
The DB cluster identifier for the cluster being modified. This parameter is not case-sensitive.
Constraints:
-
Must match the identifier of an existing DBCluster.
Type: String
Required: Yes
-
- DBClusterParameterGroupName
-
The name of the DB cluster parameter group to use for the DB cluster.
Type: String
Required: No
- DBInstanceParameterGroupName
-
The name of the DB parameter group to apply to all instances of the DB cluster.
Note
When you apply a parameter group using
DBInstanceParameterGroupName
, parameter changes aren't applied during the next maintenance window but instead are applied immediately.Default: The existing name setting
Constraints:
-
The DB parameter group must be in the same DB parameter group family as the target DB cluster version.
-
The
DBInstanceParameterGroupName
parameter is only valid in combination with theAllowMajorVersionUpgrade
parameter.
Type: String
Required: No
-
- DeletionProtection
-
A value that indicates whether the DB cluster has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled.
Type: Boolean

True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.
Default:
false
Type: Boolean
Required: No
- EngineVersion
-
The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless the
ApplyImmediately
parameter is set to true.For a list of valid engine versions, see Engine Releases for Amazon Neptune, or call DescribeDBEngineVersions.
Type: String
Required: No

Constraints: Value must be
1150-65535
Default: The same port as the original DB cluster.
Type: Integer
Required: No
- PreferredBackupWindow
-
The daily time range during which automated backups are created if automated backups are enabled, using the
