Parameters:

DBInstanceIdentifier (string) –
[REQUIRED]

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

Constraints:
- Must match the identifier of an existing DBInstance.
AllocatedStorage (integer) –
The new amount of storage in gibibytes (GiB) to allocate for the DB instance.

For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

For the valid values for allocated storage for each engine, see CreateDBInstance.
DBInstanceClass (string) –
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 Web Services Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide or Aurora DB instance classes in the Amazon Aurora User Guide. For RDS Custom, see DB instance class support for RDS Custom for Oracle and DB instance class support for RDS Custom for SQL Server.

If you modify the DB instance class, an outage occurs during the change. The change is applied during the next maintenance window, unless you specify ApplyImmediately in your request.

Default: Uses existing setting
DBSubnetGroupName (string) –
The new DB subnet group for the DB instance. You can use this parameter to move your DB instance to a different VPC. If your DB instance isn’t in a VPC, you can also use this parameter to move your DB instance into a VPC. For more information, see Working with a DB instance in a VPC in the Amazon RDS User Guide.

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

This parameter doesn’t apply to RDS Custom.

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

Example: mydbsubnetgroup
DBSecurityGroups (list) –
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.

This setting doesn’t apply to RDS Custom.

Constraints:
- If supplied, must match existing DBSecurityGroups.
- (string) –
VpcSecurityGroupIds (list) –
A list of Amazon EC2 VPC security groups to authorize on this DB instance. This change is asynchronously applied as soon as possible.

This setting doesn’t apply to RDS Custom.

Amazon Aurora

Not applicable. The associated list of EC2 VPC security groups is managed by the DB cluster. For more information, see ModifyDBCluster.

Constraints:
- If supplied, must match existing VpcSecurityGroupIds.
- (string) –
ApplyImmediately (boolean) –
A value that indicates 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. By default, this parameter is disabled.

If this parameter is disabled, 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. Review the table of parameters in Modifying a DB Instance in the Amazon RDS User Guide to see the impact of enabling or disabling ApplyImmediately for each modified parameter and to determine when the changes are applied.
MasterUserPassword (string) –
The new password for the master user. The password can include any printable ASCII character except “/”, “””, or “@”.

Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible. Between the time of the request and the completion of the request, the MasterUserPassword element exists in the PendingModifiedValues element of the operation response.

This setting doesn’t apply to RDS Custom.

Amazon Aurora

Not applicable. The password for the master user is managed by the DB cluster. For more information, see ModifyDBCluster.

Default: Uses existing setting

Constraints: Can’t be specified if ManageMasterUserPassword is turned on.

MariaDB

Constraints: Must contain from 8 to 41 characters.

Microsoft SQL Server

Constraints: Must contain from 8 to 128 characters.

MySQL

Constraints: Must contain from 8 to 41 characters.

Oracle

Constraints: Must contain from 8 to 30 characters.

PostgreSQL

Constraints: Must contain from 8 to 128 characters.

Note

Amazon RDS API operations never return the password, so this action provides a way to regain access to a primary instance user if the password is lost. This includes restoring privileges that might have been accidentally revoked.
DBParameterGroupName (string) –
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. In this case, the DB instance isn’t rebooted automatically, and the parameter changes aren’t applied during the next maintenance window. However, if you modify dynamic parameters in the newly associated DB parameter group, these changes are applied immediately without a reboot.

This setting doesn’t apply to RDS Custom.

Default: Uses existing setting

Constraints: The DB parameter group must be in the same DB parameter group family as the DB instance.
BackupRetentionPeriod (integer) –
The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

Note

Enabling and disabling backups can result in a brief I/O suspension that lasts from a few seconds to a few minutes, depending on the size and class of your DB instance.

These changes are applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If you change the parameter from one non-zero value to another non-zero value, the change is asynchronously applied as soon as possible.

Amazon Aurora

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

Default: Uses existing setting

Constraints:
- It must be a value from 0 to 35. It can’t be set to 0 if the DB instance is a source to read replicas. It can’t be set to 0 for an RDS Custom for Oracle DB instance.
- It can be specified for a MySQL read replica only if the source is running MySQL 5.6 or later.
- It can be specified for a PostgreSQL read replica only if the source is running PostgreSQL 9.3.5.
PreferredBackupWindow (string) –
The daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod parameter. Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible. The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Web Services Region. For more information, see Backup window in the Amazon RDS User Guide.

Amazon Aurora

Not applicable. The daily time range for creating automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Constraints:
- Must be in the format hh24:mi-hh24:mi
- Must be in Universal Time Coordinated (UTC)
- Must not conflict with the preferred maintenance window
- Must be at least 30 minutes
PreferredMaintenanceWindow (string) –
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, then changing this parameter will cause a reboot of the DB instance. If 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 pending changes are applied.

For more information, see Amazon RDS Maintenance Window in the Amazon RDS User Guide.

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
MultiAZ (boolean) –
A value that indicates whether the DB instance is a Multi-AZ deployment. Changing this parameter doesn’t result in an outage. The change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request.

This setting doesn’t apply to RDS Custom.
EngineVersion (string) –
The version number of the database engine to upgrade to. Changing this parameter results in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request.

For major version upgrades, if a nondefault DB parameter group is currently in use, a new DB parameter group in the DB parameter group family for the new engine version must be specified. The new DB parameter group can be the default for that DB parameter group family.

If you specify only a major version, Amazon RDS will update the DB instance to the default minor version if the current minor version is lower. For information about valid engine versions, see CreateDBInstance, or call DescribeDBEngineVersions.

If the instance that you’re modifying is acting as a read replica, the engine version that you specify must be the same or later than the version that the source DB instance or cluster is running.

In RDS Custom for Oracle, this parameter is supported for read replicas only if they are in the PATCH_DB_FAILURE lifecycle.
AllowMajorVersionUpgrade (boolean) –
A value that indicates whether major version upgrades are allowed. Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible.

This setting doesn’t apply to RDS Custom.

Constraints: Major version upgrades must be allowed when specifying a value for the EngineVersion parameter that is a different major version than the DB instance’s current version.
AutoMinorVersionUpgrade (boolean) –
A value that indicates whether minor version upgrades are applied automatically to the DB instance during the maintenance window. An outage occurs when all the following conditions are met:
- The automatic upgrade is enabled for the maintenance window.
- A newer minor version is available.
- RDS has enabled automatic patching for the engine version.
If any of the preceding conditions isn’t met, RDS applies the change as soon as possible and doesn’t cause an outage.

For an RDS Custom DB instance, set AutoMinorVersionUpgrade to false. Otherwise, the operation returns an error.
LicenseModel (string) –
The license model for the DB instance.

This setting doesn’t apply to RDS Custom.

Valid values: license-included | bring-your-own-license | general-public-license
Iops (integer) –
The new Provisioned IOPS (I/O operations per second) value for the RDS instance.

Changing this setting doesn’t result in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If you are migrating from Provisioned IOPS to standard storage, set this value to 0. The DB instance will require a reboot for the change in storage type to take effect.

If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a read replica for the instance, and creating a DB snapshot of the instance.

Constraints: For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

Default: Uses existing setting
OptionGroupName (string) –
A value that indicates the DB instance should be associated with the specified option group.

Changing this parameter doesn’t result in an outage, with one exception. If the parameter change results in an option group that enables OEM, it can cause a brief period, lasting less than a second, during which new connections are rejected but existing connections aren’t interrupted.

The change is applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request.

Permanent options, such as the TDE option for Oracle Advanced Security TDE, can’t be removed from an option group, and that option group can’t be removed from a DB instance after it is associated with a DB instance.

This setting doesn’t apply to RDS Custom.
NewDBInstanceIdentifier (string) –
The new DB instance identifier for the DB instance when renaming a DB instance. When you change the DB instance identifier, an instance reboot occurs immediately if you enable ApplyImmediately, or will occur during the next maintenance window if you disable Apply Immediately. This value is stored as a lowercase string.

This setting doesn’t apply to RDS Custom.

Constraints:
- Must contain from 1 to 63 letters, numbers, or hyphens.
- The first character must be a letter.
- Can’t end with a hyphen or contain two consecutive hyphens.
Example: mydbinstance
StorageType (string) –
Specifies the storage type to be associated with the DB instance.

If you specify Provisioned IOPS ( io1), you must also include a value for the Iops parameter.

If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a read replica for the instance, and creating a DB snapshot of the instance.

Valid values: gp2 | gp3 | io1 | standard

Default: io1 if the Iops parameter is specified, otherwise gp2
TdeCredentialArn (string) –
The ARN from the key store with which to associate the instance for TDE encryption.

This setting doesn’t apply to RDS Custom.
TdeCredentialPassword (string) –
The password for the given ARN from the key store in order to access the device.

This setting doesn’t apply to RDS Custom.
CACertificateIdentifier (string) –
Specifies the CA certificate identifier to use for the DB instance’s server certificate.

This setting doesn’t apply to RDS Custom.

For more information, see Using SSL/TLS to encrypt a connection to a DB instance in the Amazon RDS User Guide and Using SSL/TLS to encrypt a connection to a DB cluster in the Amazon Aurora User Guide.
Domain (string) –
The Active Directory directory ID to move the DB instance to. Specify none to remove the instance from its current domain. You must create the domain before this operation. Currently, you can create only MySQL, Microsoft SQL Server, Oracle, and PostgreSQL DB instances in an Active Directory Domain.

For more information, see Kerberos Authentication in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.
CopyTagsToSnapshot (boolean) –
A value that indicates whether to copy all tags from the DB instance to snapshots of the DB instance. By default, tags are not copied.

Amazon Aurora

Not applicable. Copying tags to snapshots is managed by the DB cluster. Setting this value for an Aurora DB instance has no effect on the DB cluster setting. For more information, see ModifyDBCluster.
MonitoringInterval (integer) –
The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0, which is the default.

If MonitoringRoleArn is specified, set MonitoringInterval to a value other than 0.

This setting doesn’t apply to RDS Custom.

Valid Values: 0, 1, 5, 10, 15, 30, 60
DBPortNumber (integer) –
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.

If you change the DBPortNumber value, your database restarts regardless of the value of the ApplyImmediately parameter.

This setting doesn’t apply to RDS Custom.

MySQL

Default: 3306

Valid values: 1150-65535

MariaDB

Default: 3306

Valid values: 1150-65535

PostgreSQL

Default: 5432

Valid values: 1150-65535

Type: Integer

Oracle

Default: 1521

Valid values: 1150-65535

SQL Server

Default: 1433

Valid values: 1150-65535 except 1234, 1434, 3260, 3343, 3389, 47001, and 49152-49156.

Amazon Aurora

Default: 3306

Valid values: 1150-65535
PubliclyAccessible (boolean) –
A value that indicates whether the DB instance is publicly accessible.

When the DB cluster is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB cluster’s virtual private cloud (VPC). It resolves to the public IP address from outside of the DB cluster’s VPC. Access to the DB cluster is ultimately controlled by the security group it uses. That public access isn’t permitted if the security group assigned to the DB cluster doesn’t permit it.

When the DB instance isn’t publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

PubliclyAccessible only applies to DB instances in a VPC. The DB instance must be part of a public subnet and PubliclyAccessible must be enabled for it to be publicly accessible.

Changes to the PubliclyAccessible parameter are applied immediately regardless of the value of the ApplyImmediately parameter.
MonitoringRoleArn (string) –
The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess. For information on creating a monitoring role, see To create an IAM role for Amazon RDS Enhanced Monitoring in the Amazon RDS User Guide.

If MonitoringInterval is set to a value other than 0, supply a MonitoringRoleArn value.

This setting doesn’t apply to RDS Custom.
DomainIAMRoleName (string) –
The name of the IAM role to use when making API calls to the Directory Service.

This setting doesn’t apply to RDS Custom.
PromotionTier (integer) –
A value that specifies the order in which an Aurora Replica is promoted to the primary instance after a failure of the existing primary instance. For more information, see Fault Tolerance for an Aurora DB Cluster in the Amazon Aurora User Guide.

This setting doesn’t apply to RDS Custom.

Default: 1

Valid Values: 0 - 15
EnableIAMDatabaseAuthentication (boolean) –
A value that indicates whether to enable mapping of Amazon Web Services Identity and Access Management (IAM) accounts to database accounts. By default, mapping isn’t enabled.

This setting doesn’t apply to Amazon Aurora. Mapping Amazon Web Services IAM accounts to database accounts is managed by the DB cluster.

For more information about IAM database authentication, see IAM Database Authentication for MySQL and PostgreSQL in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.
EnablePerformanceInsights (boolean) –
A value that indicates whether to enable Performance Insights for the DB instance.

For more information, see Using Amazon Performance Insights in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.
PerformanceInsightsKMSKeyId (string) –
The Amazon Web Services KMS key identifier for encryption of Performance Insights data.

The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.

If you do not specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses your default KMS key. There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

This setting doesn’t apply to RDS Custom.
PerformanceInsightsRetentionPeriod (integer) –
The number of days to retain Performance Insights data. The default is 7 days. The following values are valid:
- 7
- month * 31, where month is a number of months from 1-23
- 731
For example, the following values are valid:
- 93 (3 months * 31)
- 341 (11 months * 31)
- 589 (19 months * 31)
- 731
If you specify a retention period such as 94, which isn’t a valid value, RDS issues an error.

This setting doesn’t apply to RDS Custom.
CloudwatchLogsExportConfiguration (dict) –
The configuration setting for the log types to be enabled for export to CloudWatch Logs for a specific DB instance.

A change to the CloudwatchLogsExportConfiguration parameter is always applied to the DB instance immediately. Therefore, the ApplyImmediately parameter has no effect.

This setting doesn’t apply to RDS Custom.
- EnableLogTypes (list) –
  
  The list of log types to enable.
  - (string) –
- DisableLogTypes (list) –
  
  The list of log types to disable.
  - (string) –
ProcessorFeatures (list) –
The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

This setting doesn’t apply to RDS Custom.
- (dict) –
  
  Contains the processor features of a DB instance class.
  
  To specify the number of CPU cores, use the coreCount feature name for the Name parameter. To specify the number of threads per core, use the threadsPerCore feature name for the Name parameter.
  
  You can set the processor features of the DB instance class for a DB instance when you call one of the following actions:
  - CreateDBInstance
  - ModifyDBInstance
  - RestoreDBInstanceFromDBSnapshot
  - RestoreDBInstanceFromS3
  - RestoreDBInstanceToPointInTime
  You can view the valid processor values for a particular instance class by calling the DescribeOrderableDBInstanceOptions action and specifying the instance class for the DBInstanceClass parameter.
  
  In addition, you can use the following actions for DB instance class processor information:
  - DescribeDBInstances
  - DescribeDBSnapshots
  - DescribeValidDBInstanceModifications
  If you call DescribeDBInstances, ProcessorFeature returns non-null values only if the following conditions are met:
  - You are accessing an Oracle DB instance.
  - Your Oracle DB instance class supports configuring the number of CPU cores and threads per core.
  - The current number CPU cores and threads is set to a non-default value.
  For more information, see Configuring the Processor of the DB Instance Class in the Amazon RDS User Guide.
  - Name (string) –
    
    The name of the processor feature. Valid names are coreCount and threadsPerCore.
  - Value (string) –
    
    The value of a processor feature name.
UseDefaultProcessorFeatures (boolean) –
A value that indicates whether the DB instance class of the DB instance uses its default processor features.

This setting doesn’t apply to RDS Custom.
DeletionProtection (boolean) – 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 isn’t enabled. For more information, see Deleting a DB Instance.
MaxAllocatedStorage (integer) –
The upper limit in gibibytes (GiB) to which Amazon RDS can automatically scale the storage of the DB instance.

For more information about this setting, including limitations that apply to it, see Managing capacity automatically with Amazon RDS storage autoscaling in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.
CertificateRotationRestart (boolean) –
A value that indicates whether the DB instance is restarted when you rotate your SSL/TLS certificate.

By default, the DB instance is restarted when you rotate your SSL/TLS certificate. The certificate is not updated until the DB instance is restarted.

Warning

Set this parameter only if you are not using SSL/TLS to connect to the DB instance.

If you are using SSL/TLS to connect to the DB instance, follow the appropriate instructions for your DB engine to rotate your SSL/TLS certificate:
- For more information about rotating your SSL/TLS certificate for RDS DB engines, see Rotating Your SSL/TLS Certificate. in the Amazon RDS User Guide.
- For more information about rotating your SSL/TLS certificate for Aurora DB engines, see Rotating Your SSL/TLS Certificate in the Amazon Aurora User Guide.
This setting doesn’t apply to RDS Custom.
ReplicaMode (string) –
A value that sets the open mode of a replica database to either mounted or read-only.

Note

Currently, this parameter is only supported for Oracle DB instances.

Mounted DB replicas are included in Oracle Enterprise Edition. The main use case for mounted replicas is cross-Region disaster recovery. The primary database doesn’t use Active Data Guard to transmit information to the mounted replica. Because it doesn’t accept user connections, a mounted replica can’t serve a read-only workload. For more information, see Working with Oracle Read Replicas for Amazon RDS in the Amazon RDS User Guide.

This setting doesn’t apply to RDS Custom.
EnableCustomerOwnedIp (boolean) –
A value that indicates whether to enable a customer-owned IP address (CoIP) for an RDS on Outposts DB instance.

A CoIP provides local or external connectivity to resources in your Outpost subnets through your on-premises network. For some use cases, a CoIP can provide lower latency for connections to the DB instance from outside of its virtual private cloud (VPC) on your local network.

For more information about RDS on Outposts, see Working with Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.

For more information about CoIPs, see Customer-owned IP addresses in the Amazon Web Services Outposts User Guide.
AwsBackupRecoveryPointArn (string) –
The Amazon Resource Name (ARN) of the recovery point in Amazon Web Services Backup.

This setting doesn’t apply to RDS Custom.
AutomationMode (string) – The automation mode of the RDS Custom DB instance: full or all paused. If full, the DB instance automates monitoring and instance recovery. If all paused, the instance pauses automation for the duration set by ResumeFullAutomationModeMinutes.
ResumeFullAutomationModeMinutes (integer) – The number of minutes to pause the automation. When the time period ends, RDS Custom resumes full automation. The minimum value is 60 (default). The maximum value is 1,440.
NetworkType (string) –
The network type of the DB instance.

Valid values:
- IPV4
- DUAL
The network type is determined by the DBSubnetGroup specified for the DB instance. A DBSubnetGroup can support only the IPv4 protocol or the IPv4 and the IPv6 protocols ( DUAL).

For more information, see Working with a DB instance in a VPC in the Amazon RDS User Guide.
StorageThroughput (integer) –
Specifies the storage throughput value for the DB instance.

This setting applies only to the gp3 storage type.

This setting doesn’t apply to RDS Custom or Amazon Aurora.
ManageMasterUserPassword (boolean) –
A value that indicates whether to manage the master user password with Amazon Web Services Secrets Manager.

If the DB cluster doesn’t manage the master user password with Amazon Web Services Secrets Manager, you can turn on this management. In this case, you can’t specify MasterUserPassword.

If the DB cluster already manages the master user password with Amazon Web Services Secrets Manager, and you specify that the master user password is not managed with Amazon Web Services Secrets Manager, then you must specify MasterUserPassword. In this case, RDS deletes the secret and uses the new password for the master user specified by MasterUserPassword.

For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide.

Constraints:
- Can’t manage the master user password with Amazon Web Services Secrets Manager if MasterUserPassword is specified.
RotateMasterUserPassword (boolean) –
A value that indicates whether to rotate the secret managed by Amazon Web Services Secrets Manager for the master user password.

This setting is valid only if the master user password is managed by RDS in Amazon Web Services Secrets Manager for the DB cluster. The secret value contains the updated password.

For more information, see Password management with Amazon Web Services Secrets Manager in the Amazon RDS User Guide.

Constraints:
- You must apply the change immediately when rotating the master user password.
MasterUserSecretKmsKeyId (string) –
The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.

This setting is valid only if both of the following conditions are met:
- The DB instance doesn’t manage the master user password in Amazon Web Services Secrets Manager. If the DB instance already manages the master user password in Amazon Web Services Secrets Manager, you can’t change the KMS key used to encrypt the secret.
- You are turning on ManageMasterUserPassword to manage the master user password in Amazon Web Services Secrets Manager. If you are turning on ManageMasterUserPassword and don’t specify MasterUserSecretKmsKeyId, then the aws/secretsmanager KMS key is used to encrypt the secret. If the secret is in a different Amazon Web Services account, then you can’t use the aws/secretsmanager KMS key to encrypt the secret, and you must use a customer managed KMS key.
The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.
