modifyDBInstance method
Modifies settings for an instance. You can change one or more database configuration parameters by specifying these parameters and the new values in the request.
May throw InvalidDBInstanceStateFault. May throw InvalidDBSecurityGroupStateFault. May throw DBInstanceAlreadyExistsFault. May throw DBInstanceNotFoundFault. May throw DBSecurityGroupNotFoundFault. May throw DBParameterGroupNotFoundFault. May throw InsufficientDBInstanceCapacityFault. May throw StorageQuotaExceededFault. May throw InvalidVPCNetworkStateFault. May throw DBUpgradeDependencyFailureFault. May throw StorageTypeNotSupportedFault. May throw AuthorizationNotFoundFault. May throw CertificateNotFoundFault.
Parameter dBInstanceIdentifier
:
The instance identifier. This value is stored as a lowercase string.
Constraints:
-
Must match the identifier of an existing
DBInstance
.
Parameter 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 instance.
If this parameter is set to false
, changes to the instance
are applied during the next maintenance window. Some parameter changes can
cause an outage and are applied on the next reboot.
Default: false
Parameter autoMinorVersionUpgrade
:
Indicates that minor version upgrades are applied automatically to the
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 results if this
parameter is set to true
during the maintenance window, and a
newer minor version is available, and Amazon DocumentDB has enabled
automatic patching for that engine version.
Parameter cACertificateIdentifier
:
Indicates the certificate that needs to be associated with the instance.
Parameter dBInstanceClass
:
The new compute and memory capacity of the instance; for example,
db.r5.large
. Not all instance classes are available in all
AWS Regions.
If you modify the 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.
Parameter newDBInstanceIdentifier
:
The new instance identifier for the instance when renaming an instance.
When you change the instance identifier, an instance reboot occurs
immediately if you set Apply Immediately
to
true
. It occurs during the next maintenance window if you set
Apply Immediately
to false
. This value is stored
as a lowercase string.
Constraints:
- Must contain from 1 to 63 letters, numbers, or hyphens.
- The first character must be a letter.
- Cannot end with a hyphen or contain two consecutive hyphens.
mydbinstance
Parameter preferredMaintenanceWindow
:
The weekly time range (in UTC) during which system maintenance can occur,
which might result in an outage. 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, changing this parameter causes a reboot of the instance. If
you are moving this window to the current time, there must be at least 30
minutes between the current time and end of the window to ensure that
pending changes are applied.
Default: Uses existing setting.
Format: ddd:hh24:mi-ddd:hh24:mi
Valid days: Mon, Tue, Wed, Thu, Fri, Sat, Sun
Constraints: Must be at least 30 minutes.
Parameter promotionTier
:
A value that specifies the order in which an Amazon DocumentDB replica is
promoted to the primary instance after a failure of the existing primary
instance.
Default: 1
Valid values: 0-15
