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 will be available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance will be 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.
string
The new compute and memory capacity of the DB instance. To determine the instance classes that are available for a particular DB engine, use the DescribeOrderableDBInstanceOptions action.
Passing a value for this setting causes an outage during the change and is applied during the next maintenance window, unless ApplyImmediately is specified as true for this request.
Default: Uses existing setting
Valid Values: db.t1.micro | db.m1.small | db.m1.medium | db.m1.large | db.m1.xlarge | db.m2.xlarge | db.m2.2xlarge | db.m2.4xlarge | db.m3.medium | db.m3.large | db.m3.xlarge | db.m3.2xlarge | db.m4.large | db.m4.xlarge | db.m4.2xlarge | db.m4.4xlarge | db.m4.10xlarge | db.r3.large | db.r3.xlarge | db.r3.2xlarge | db.r3.4xlarge | db.r3.8xlarge | db.t2.micro | db.t2.small | db.t2.medium | db.t2.large
list
A list of DB security groups to authorize on this DB instance. Changing this setting does not result in an outage and the change is asynchronously applied as soon as possible.
Constraints:
Must be 1 to 255 alphanumeric characters
First character must be a letter
Cannot end with a hyphen or contain two consecutive hyphens
(string) --
list
A list of EC2 VPC security groups to authorize on this DB instance. This change is asynchronously applied as soon as possible.
Constraints:
Must be 1 to 255 alphanumeric characters
First character must be a letter
Cannot end with a hyphen or contain two consecutive hyphens
(string) --
boolean
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 will be applied on the next call to RebootDBInstance, or the next failure reboot. Review the table of parameters in Modifying a DB Instance and Using the Apply Immediately Parameter to see the impact that setting ApplyImmediately to true or false has for each modified parameter and to determine when the changes will be applied.
Default: false
string
The new password for the DB instance master user. Can be any printable ASCII character except "/", """, or "@".
Changing this parameter does not 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.
Default: Uses existing setting
Constraints: Must be 8 to 41 alphanumeric characters (MySQL, MariaDB, and Amazon Aurora), 8 to 30 alphanumeric characters (Oracle), or 8 to 128 alphanumeric characters (SQL Server).
Note
Amazon RDS API actions 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.
string
The name of the DB parameter group to apply to the DB instance. Changing this setting does not 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.
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.
Changing this parameter can result in an outage if you change from 0 to a non-zero value or from a non-zero value to 0. These changes are applied during the next maintenance window unless the ApplyImmediately parameter is set to true 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.
Default: Uses existing setting
Constraints:
Must be a value from 0 to 35
Can be specified for a MySQL Read Replica only if the source is running MySQL 5.6
Can be specified for a PostgreSQL Read Replica only if the source is running PostgreSQL 9.3.5
Cannot be set to 0 if the DB instance is a source to Read Replicas
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 does not result in an outage and the change is asynchronously applied as soon as possible.
Constraints:
Must be in the format hh24:mi-hh24:mi
Times should be in Universal Time Coordinated (UTC)
Must not conflict with the preferred maintenance window
Must be at least 30 minutes
string
The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter does not 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.
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
boolean
Specifies if the DB instance is a Multi-AZ deployment. Changing this parameter does not result in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true for this request.
Constraints: Cannot be specified if the DB instance is a Read Replica. This parameter cannot be used with SQL Server DB instances. Multi-AZ for SQL Server DB instances is set using the Mirroring option in an option group associated with the DB instance.
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 set to true for this request.
For major version upgrades, if a non-default 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.
For a list of valid engine versions, see CreateDBInstance.
boolean
Indicates that major version upgrades are allowed. Changing this parameter does not result in an outage and the change is asynchronously applied as soon as possible.
Constraints: This parameter must be set to true when specifying a value for the EngineVersion parameter that is a different major version than the DB instance's current version.
boolean
Indicates that minor version upgrades will be applied automatically to the DB instance during the maintenance window. Changing this parameter does not 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 RDS has enabled auto patching for that engine version.
integer
The new Provisioned IOPS (I/O operations per second) value for the RDS instance. Changing this setting does not result in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true for this request.
Default: Uses existing setting
Constraints: 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. 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.
SQL Server
Setting the IOPS value for the SQL Server database engine is not supported.
Type: Integer
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 will be available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance will be 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.
string
Indicates that the DB instance should be associated with the specified option group. Changing this parameter does not result in an outage except in the following case and the change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.
Permanent options, such as the TDE option for Oracle Advanced Security TDE, cannot be removed from an option group, and that option group cannot be removed from a DB instance once it is associated with a DB instance
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 will occur immediately if you set Apply Immediately to true, or will occur during the next maintenance window if Apply Immediately to false. This value is stored as a lowercase string.
Constraints:
Must contain from 1 to 63 alphanumeric characters or hyphens
First character must be a letter
Cannot end with a hyphen or contain two consecutive hyphens
string
Specifies the storage type to be associated with the DB instance.
Valid values: standard | gp2 | io1
If you specify io1 , you must also include a value for the Iops parameter.
Default: io1 if the Iops parameter is specified; otherwise standard
string
The ARN from the Key Store with which to associate the instance for TDE encryption.
string
The password for the given ARN from the Key Store in order to access the device.
string
Indicates the certificate that needs to be associated with the instance.
boolean
True to copy all tags from the DB instance to snapshots of the DB instance; otherwise false. The default is false.
integer
The port number on which the database accepts connections.
MySQL
Default: 3306

Valid Values: 1150-65535 except for 1434 , 3389 , 47001 , 49152 , and 49152 through 49156 .
Amazon Aurora
Default: 3306
Valid Values: 1150-65535
boolean
True to make the DB instance Internet-facing with a publicly resolvable DNS name, which resolves to a public IP address. False to make the DB instance internal 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 true in order for it to be publicly accessible.
