Note the following requirements:

Note the following limitations:

Type: String

Required: No

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 updates 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 higher 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.

Constraints:

Type: String

Required: No

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:

Default: Uses existing setting

Type: Integer

Required: No

The license model for the DB instance.

This setting doesn't apply to Amazon Aurora or RDS Custom DB instances.

Valid Values:

Type: String

Required: No

Specifies whether to manage the master user password with AWS Secrets Manager.

If the DB instance doesn't manage the master user password with AWS Secrets Manager, you can turn on this management. In this case, you can't specify MasterUserPassword.

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

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

Constraints:

Type: Boolean

Required: No

The new password for the master user.

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.

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

This setting doesn't apply to RDS Custom DB instances.

Type: String

Required: No

Specifies 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 DB instances.

Type: Boolean

Required: No

Specifies whether the to convert your DB instance from the single-tenant configuration to the multi-tenant configuration. This parameter is supported only for RDS for Oracle CDB instances.

During the conversion, RDS creates an initial tenant database and associates the DB name, master user name, character set, and national character set metadata with this database. The tags associated with the instance also propagate to the initial tenant database. You can add more tenant databases to your DB instance by using the CreateTenantDatabase operation.

Type: Boolean

Required: No

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 ApplyImmediately. This value is stored as a lowercase string.

This setting doesn't apply to RDS Custom DB instances.

Constraints:

Example: mydbinstance

Type: String

Required: No

The option group to associate the DB instance with.

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 DB instances.

Type: String

Required: No

The AWS KMS key identifier for encryption of Performance Insights data.

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.

If you don't specify a value for PerformanceInsightsKMSKeyId, then Amazon RDS uses your default KMS key. There is a default KMS key for your AWS account. Your AWS account has a different default KMS key for each AWS Region.

This setting doesn't apply to RDS Custom DB instances.

Type: String

Required: No

The number of days to retain Performance Insights data.

This setting doesn't apply to RDS Custom DB instances.

Valid Values:

Default: 7 days

If you specify a retention period that isn't valid, such as 94, Amazon RDS returns an error.

Type: Integer

Required: No

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 AWS Region. For more information, see Backup window in the Amazon RDS User Guide.

This setting doesn't apply to Amazon Aurora DB instances. The daily time range for creating automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Constraints:

Type: String

Required: No

The weekly time range 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 causes a reboot of the DB instance. If you change 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

Constraints:

Type: String

Required: No

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 DB instances.

Type: Array of ProcessorFeature objects

Required: No

This setting doesn't apply to RDS Custom DB instances.

Default: 1

Valid Values: 0 - 15

Type: Integer

Required: No

Specifies whether the DB instance is publicly accessible.

When the DB instance is publicly accessible and you connect from outside of the DB instance's virtual private cloud (VPC), its Domain Name System (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB instance, the endpoint resolves to the private IP address. Access to the DB instance is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB instance 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.

Type: Boolean

Required: No

A value that sets the open mode of a replica database to either mounted or read-only.

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 DB instances.

Type: String

Valid Values: open-read-only | mounted

Required: No

If you specify io1, io2, or gp3 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.
