Properties

NameTypeDescription
Public Property AllocatedStorage System.Int32

Gets and sets the property AllocatedStorage.

Not supported by Neptune.

Public Property AllowMajorVersionUpgrade System.Boolean

Gets and sets the property AllowMajorVersionUpgrade.

Indicates that major version upgrades are allowed. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.

Public Property ApplyImmediately System.Boolean

Gets and sets the property ApplyImmediately.

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 instance.

If this parameter is set to false, changes to the DB instance are applied during the next maintenance window. Some parameter changes can cause an outage and are applied on the next call to RebootDBInstance, or the next failure reboot.

Default: false

Public Property AutoMinorVersionUpgrade System.Boolean

Gets and sets the property AutoMinorVersionUpgrade.

Indicates that minor version upgrades are applied automatically to the DB instance during the maintenance window. Changing this parameter doesn't result in an outage except in the following case and the change is asynchronously applied as soon as possible. An outage will result if this parameter is set to true during the maintenance window, and a newer minor version is available, and Neptune has enabled auto patching for that engine version.

Public Property BackupRetentionPeriod System.Int32

Gets and sets the property BackupRetentionPeriod.

Not applicable. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Default: Uses existing setting

Public Property DBInstanceClass System.String

Gets and sets the property DBInstanceClass.

The new compute and memory capacity of the DB instance, for example, db.m4.large. Not all DB instance classes are available in all Amazon Regions.

If you modify the DB instance class, an outage occurs during the change. The change is applied during the next maintenance window, unless ApplyImmediately is specified as true for this request.

Default: Uses existing setting

Public Property DBInstanceIdentifier System.String

Gets and sets the property DBInstanceIdentifier.

The DB instance identifier. This value is stored as a lowercase string.

Constraints:

  • Must match the identifier of an existing DBInstance.

Public Property DBParameterGroupName System.String

Gets and sets the property DBParameterGroupName.

The name of the DB parameter group to apply to the DB instance. Changing this setting doesn't result in an outage. The parameter group name itself is changed immediately, but the actual parameter changes are not applied until you reboot the instance without failover. The db instance will NOT be rebooted automatically and the parameter changes will NOT be applied during the next maintenance window.

Default: Uses existing setting

Constraints: The DB parameter group must be in the same DB parameter group family as this DB instance.

Public Property DBPortNumber System.Int32

Gets and sets the property DBPortNumber.

The port number on which the database accepts connections.

The value of the DBPortNumber parameter must not match any of the port values specified for options in the option group for the DB instance.

Your database will restart when you change the DBPortNumber value regardless of the value of the ApplyImmediately parameter.

Default: 8182

Public Property DBSecurityGroups System.Collections.Generic.List<System.String>

Gets and sets the property DBSecurityGroups.

A list of DB security groups to authorize on this DB instance. Changing this setting doesn't result in an outage and the change is asynchronously applied as soon as possible.

Constraints:

  • If supplied, must match existing DBSecurityGroups.

Public Property DBSubnetGroupName System.String

Gets and sets the property DBSubnetGroupName.

The new DB subnet group for the DB instance. You can use this parameter to move your DB instance to a different VPC.

Changing the subnet group causes an outage during the change. The change is applied during the next maintenance window, unless you specify true for the ApplyImmediately parameter.

Constraints: If supplied, must match the name of an existing DBSubnetGroup.

Example: mySubnetGroup

Public Property DeletionProtection System.Boolean

Gets and sets the property DeletionProtection.

A value that indicates whether the DB instance has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled. See Deleting a DB Instance.

Public Property EnablePerformanceInsights System.Boolean

Gets and sets the property EnablePerformanceInsights.

(Not supported by Neptune)

Public Property EngineVersion System.String

Changing this parameter doesn't result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance.
