    The name of the NCHAR character set for the Oracle DB instance.

    This parameter doesn't apply to RDS Custom.

  • :publicly_accessible (Boolean) —

    A value that indicates whether the DB instance is publicly accessible.

    When the DB instance is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB instance's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses. That public access is not 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.

    Default: The default behavior varies depending on whether DBSubnetGroupName is specified.

    If DBSubnetGroupName isn't specified, and PubliclyAccessible isn't specified, the following applies:

    • If the default VPC in the target Region doesn’t have an internet gateway attached to it, the DB instance is private.

    • If the default VPC in the target Region has an internet gateway attached to it, the DB instance is public.

    If DBSubnetGroupName is specified, and PubliclyAccessible isn't specified, the following applies:

    • If the subnets are part of a VPC that doesn’t have an internet gateway attached to it, the DB instance is private.

    • If the subnets are part of a VPC that has an internet gateway attached to it, the DB instance is public.

  • :tags (Array<Types::Tag>) —

    Tags to assign to the DB instance.

  • :db_cluster_identifier (String) —

    The identifier of the DB cluster that the instance will belong to.

    This setting doesn't apply to RDS Custom.

  • :storage_type (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 gp2

  • :tde_credential_arn (String) —

    The ARN from the key store with which to associate the instance for TDE encryption.

    This setting doesn't apply to RDS Custom.

  • :tde_credential_password (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.

  • :storage_encrypted (Boolean) —

    A value that indicates whether the DB instance is encrypted. By default, it isn't encrypted.

    For RDS Custom Oracle instances, either set this parameter to true or leave it unset. If you set this parameter to false, RDS reports an error.

    Amazon Aurora

    Not applicable. The encryption for DB instances is managed by the DB cluster.

  • :kms_key_id (String) —

    The Amazon Web Services KMS key identifier for an encrypted DB instance.

    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.

    Amazon Aurora

    Not applicable. The Amazon Web Services KMS key identifier is managed by the DB cluster. For more information, see CreateDBCluster.

    If StorageEncrypted is enabled, and you do not specify a value for the KmsKeyId parameter, 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.

    Amazon RDS Custom

    A KMS key is required for RDS Custom Oracle instances. For most RDS engines, if you leave this parameter empty while enabling StorageEncrypted, the engine uses the default KMS key. However, RDS Custom for Oracle doesn't use the default key when this parameter is empty. You must explicitly specify a key.

  • :domain (String) —

    The Active Directory directory ID to create the DB instance in. Currently, only MySQL, Microsoft SQL Server, Oracle, and PostgreSQL DB instances can be created 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.

  • :copy_tags_to_snapshot (Boolean) —

    A value that indicates whether to copy 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.

  • :monitoring_interval (Integer) —

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collection of Enhanced Monitoring metrics, specify 0. The default is 0.

    If MonitoringRoleArn is specified, then you must 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

  • :monitoring_role_arn (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 Setting Up and Enabling Enhanced Monitoring in the Amazon RDS User Guide.

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

    This setting doesn't apply to RDS Custom.

  • :domain_iam_role_name (String) —

    Specify the name of the IAM role to be used when making API calls to the Directory Service.

    This setting doesn't apply to RDS Custom.

  • :promotion_tier (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

    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 RDS Custom or Amazon Aurora. In Aurora, mapping Amazon Web Services IAM accounts to database accounts is managed by the DB cluster.

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

  • :enable_performance_insights (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 Relational Database Service User Guide.

    This setting doesn't apply to RDS Custom.

  • :performance_insights_kms_key_id (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.

  • :performance_insights_retention_period (Integer) —

    The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

    This setting doesn't apply to RDS Custom.

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :db_instance_identifier (required, String) —

    The DB instance identifier of the read replica. This identifier is the unique key that identifies a DB instance. This parameter is stored as a lowercase string.

  • :db_instance_class (String) —

    The compute and memory capacity of the read replica, 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.

    Default: Inherits from the source DB instance.

  • :availability_zone (String) —

    The Availability Zone (AZ) where the read replica will be created.

    Default: A random, system-chosen Availability Zone in the endpoint's Amazon Web Services Region.

    Example: us-east-1d

  • :port (Integer) —

    The port number that the DB instance uses for connections.

    Default: Inherits from the source DB instance

    Valid Values: 1150-65535

  • :multi_az (Boolean) —

    A value that indicates whether the read replica is in a Multi-AZ deployment.

    You can create a read replica as a Multi-AZ DB instance. RDS creates a standby of your replica in another Availability Zone for failover support for the replica. Creating your read replica as a Multi-AZ DB instance is independent of whether the source database is a Multi-AZ DB instance.

    This setting doesn't apply to RDS Custom.

  • :auto_minor_version_upgrade (Boolean) —

    A value that indicates whether minor engine upgrades are applied automatically to the read replica during the maintenance window.

    This setting doesn't apply to RDS Custom.

    Default: Inherits from the source DB instance

  • :iops (Integer) —

    The amount of Provisioned IOPS (input/output operations per second) to be initially allocated for the DB instance.

  • :option_group_name (String) —

    The option group the DB instance is associated with. If omitted, the option group associated with the source instance is used.

    For SQL Server, you must use the option group associated with the source instance.

    This setting doesn't apply to RDS Custom.

  • :db_parameter_group_name (String) —

    The name of the DB parameter group to associate with this DB instance.

    If you do not specify a value for DBParameterGroupName, then Amazon RDS uses the DBParameterGroup of source DB instance for a same Region read replica, or the default DBParameterGroup for the specified DB engine for a cross-Region read replica.

    Specifying a parameter group for this operation is only supported for Oracle DB instances. It isn't supported for RDS Custom.

    Constraints:

    • Must be 1 to 255 letters, numbers, or hyphens.

    • First character must be a letter

    • Can't end with a hyphen or contain two consecutive hyphens

  • :publicly_accessible (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.

    For more information, see CreateDBInstance.

  • :tags (Array<Types::Tag>) —

    A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.

  • :db_subnet_group_name (String) —

    Specifies a DB subnet group for the DB instance. The new DB instance is created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance isn't created in a VPC.

    Constraints:

    • Can only be specified if the source DB instance identifier specifies a DB instance in another Amazon Web Services Region.

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

    • The specified DB subnet group must be in the same Amazon Web Services Region in which the operation is running.

    • All read replicas in one Amazon Web Services Region that are created from the same source DB instance must either:>

      • Specify DB subnet groups from the same VPC. All these read replicas are created in the same VPC.

      • Not specify a DB subnet group. All these read replicas are created outside of any VPC.

    Example: mySubnetgroup

  • :vpc_security_group_ids (Array<String>) —

    A list of Amazon EC2 VPC security groups to associate with the read replica.

    This setting doesn't apply to RDS Custom.

    Default: The default EC2 VPC security group for the DB subnet group's VPC.

  • :storage_type (String) —

    Specifies the storage type to be associated with the read replica.

    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 gp2

  • :copy_tags_to_snapshot (Boolean) —

    A value that indicates whether to copy all tags from the read replica to snapshots of the read replica. By default, tags are not copied.

  • :monitoring_interval (Integer) —

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the read replica. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If MonitoringRoleArn is specified, then you must also 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

  • :monitoring_role_arn (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, go to 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, then you must supply a MonitoringRoleArn value.

    This setting doesn't apply to RDS Custom.

  • :kms_key_id (String) —

    The Amazon Web Services KMS key identifier for an encrypted read replica.

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

    If you create an encrypted read replica in the same Amazon Web Services Region as the source DB instance, then do not specify a value for this parameter. A read replica in the same Amazon Web Services Region is always encrypted with the same KMS key as the source DB instance.

    If you create an encrypted read replica in a different Amazon Web Services Region, then you must specify a KMS key identifier for the destination Amazon Web Services Region. KMS keys are specific to the Amazon Web Services Region that they are created in, and you can't use KMS keys from one Amazon Web Services Region in another Amazon Web Services Region.

    You can't create an encrypted read replica from an unencrypted DB instance.

    This setting doesn't apply to RDS Custom, which uses the same KMS key as the primary replica.

  • :pre_signed_url (String) —

    The URL that contains a Signature Version 4 signed request for the CreateDBInstanceReadReplica API action in the source Amazon Web Services Region that contains the source DB instance.

    You must specify this parameter when you create an encrypted read replica from another Amazon Web Services Region by using the Amazon RDS API. Don't specify PreSignedUrl when you are creating an encrypted read replica in the same Amazon Web Services Region.

    The presigned URL must be a valid request for the CreateDBInstanceReadReplica API action that can be executed in the source Amazon Web Services Region that contains the encrypted source DB instance. The presigned URL request must contain the following parameter values:

    • DestinationRegion - The Amazon Web Services Region that the encrypted read replica is created in. This Amazon Web Services Region is the same one where the CreateDBInstanceReadReplica action is called that contains this presigned URL.

      For example, if you create an encrypted DB instance in the us-west-1 Amazon Web Services Region, from a source DB instance in the us-east-2 Amazon Web Services Region, then you call the CreateDBInstanceReadReplica action in the us-east-1 Amazon Web Services Region and provide a presigned URL that contains a call to the CreateDBInstanceReadReplica action in the us-west-2 Amazon Web Services Region. For this example, the DestinationRegion in the presigned URL must be set to the us-east-1 Amazon Web Services Region.

    • KmsKeyId - The Amazon Web Services KMS key identifier for the key to use to encrypt the read replica in the destination Amazon Web Services Region. This is the same identifier for both the CreateDBInstanceReadReplica action that is called in the destination Amazon Web Services Region, and the action contained in the presigned URL.

    • SourceDBInstanceIdentifier - The DB instance identifier for the encrypted DB instance to be replicated. This identifier must be in the Amazon Resource Name (ARN) format for the source Amazon Web Services Region. For example, if you are creating an encrypted read replica from a DB instance in the us-west-2 Amazon Web Services Region, then your SourceDBInstanceIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115.

    To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (Amazon Web Services Signature Version 4) and Signature Version 4 Signing Process.

    If you are using an Amazon Web Services SDK tool or the CLI, you can specify SourceRegion (or --source-region for the CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a presigned URL that is a valid request for the operation that can be executed in the source Amazon Web Services Region.

    SourceRegion isn't supported for SQL Server, because SQL Server on Amazon RDS doesn't support cross-Region read replicas.

    This setting doesn't apply to RDS Custom.

  • :enable_iam_database_authentication (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.

    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.

  • :enable_performance_insights (Boolean) —

    A value that indicates whether to enable Performance Insights for the read replica.

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

    This setting doesn't apply to RDS Custom.

  • :performance_insights_kms_key_id (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.

  • :performance_insights_retention_period (Integer) —

    The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

    This setting doesn't apply to RDS Custom.

  • :enable_cloudwatch_logs_exports (Array<String>) —

    The list of logs that the new DB instance is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon RDS User Guide.

    This setting doesn't apply to RDS Custom.

  • :processor_features (Array<Types::ProcessorFeature>) —

    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.

  • :use_default_processor_features (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.

  • :deletion_protection (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.

  • :domain (String) —

    The Active Directory directory ID to create the DB instance in. Currently, only MySQL, Microsoft SQL Server, Oracle, and PostgreSQL DB instances can be created 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.

  • :domain_iam_role_name (String) —

    Specify the name of the IAM role to be used when making API calls to the Directory Service.

    This setting doesn't apply to RDS Custom.

  • :replica_mode (String) —

    The open mode of the replica database: mounted or read-only.

    This parameter is only supported for Oracle DB instances.

    Mounted DB replicas are included in Oracle Database 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.

    You can create a combination of mounted and read-only DB replicas for the same primary DB instance. For more information, see Working with Oracle Read Replicas for Amazon RDS in the Amazon RDS User Guide.

    For RDS Custom, you must specify this parameter and set it to mounted. The value won't be set by default. After replica creation, you can manage the open mode manually.

  • :max_allocated_storage (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.

  • :custom_iam_instance_profile (String) —

    The instance profile associated with the underlying Amazon EC2 instance of an RDS Custom DB instance. The instance profile must meet the following requirements:

    • The profile must exist in your account.

    • The profile must have an IAM role that Amazon EC2 has permissions to assume.

    • The instance profile name and the associated IAM role name must start with the prefix AWSRDSCustom.

    For the list of permissions required for the IAM role, see Configure IAM and your VPC in the Amazon Relational Database Service User Guide.

    This setting is required for RDS Custom.

  • :source_region (String) —

    The source region of the snapshot. This is only needed when the shapshot is encrypted and in a different region.

})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :skip_final_snapshot (Boolean) —

    A value that indicates whether to skip the creation of a final DB snapshot before deleting the instance. If you enable this parameter, RDS doesn't create a DB snapshot. If you don't enable this parameter, RDS creates a DB snapshot before the DB instance is deleted. By default, skip isn't enabled, and the DB snapshot is created.

    If you don't enable this parameter, you must specify the FinalDBSnapshotIdentifier parameter.

    When a DB instance is in a failure state and has a status of failed, incompatible-restore, or incompatible-network, RDS can delete the instance only if you enable this parameter.

    If you delete a read replica or an RDS Custom instance, you must enable this setting.

    This setting is required for RDS Custom.

  • :final_db_snapshot_identifier (String) —

    The DBSnapshotIdentifier of the new DBSnapshot created when the SkipFinalSnapshot parameter is disabled.

    If you enable this parameter and also enable SkipFinalShapshot, the command results in an error.

    This setting doesn't apply to RDS Custom.

    Constraints:

    • Must be 1 to 255 letters or numbers.

    • First character must be a letter.

    • Can't end with a hyphen or contain two consecutive hyphens.

    • Can't be specified when deleting a read replica.

Options Hash (options):

  • :allocated_storage (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.

  • :db_instance_class (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.

    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 enabled for this request.

    This setting doesn't apply to RDS Custom.

    Default: Uses existing setting

  • :db_subnet_group_name (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: mySubnetGroup

  • :db_security_groups (Array<String>) —

    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.

  • :vpc_security_group_ids (Array<String>) —

    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.

    ^

  • :apply_immediately (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.

  • :master_user_password (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

    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.

    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.

  • :db_parameter_group_name (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.

  • :backup_retention_period (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.

    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 or 35 for an RDS Custom 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.

  • :preferred_backup_window (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

  • :preferred_maintenance_window (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

  • :multi_az (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.

  • :engine_version (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.

    In RDS Custom, this parameter is supported for read replicas only if they are in the PATCH_DB_FAILURE lifecycle.

  • :allow_major_version_upgrade (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.

  • :auto_minor_version_upgrade (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.

  • :license_model (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

  • :option_group_name (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.

  • :new_db_instance_identifier (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

  • :storage_type (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: standard | gp2 | io1

    Default: io1 if the Iops parameter is specified, otherwise gp2

  • :tde_credential_arn (String) —

    The ARN from the key store with which to associate the instance for TDE encryption.

    This setting doesn't apply to RDS Custom.

    This setting doesn't apply to RDS Custom.

  • :ca_certificate_identifier (String) —

    Specifies the certificate to associate with the DB instance.

    This setting doesn't apply to RDS Custom.

  • :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.

  • :copy_tags_to_snapshot (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.

  • :monitoring_interval (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

  • :db_port_number (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

    Amazon Aurora

    Default: 3306

    Valid values: 1150-65535

  • :publicly_accessible (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.

    This setting doesn't apply to RDS Custom.

  • :monitoring_role_arn (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.

  • :domain_iam_role_name (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.

  • :promotion_tier (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

  • :enable_iam_database_authentication (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.

  • :enable_performance_insights (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 Relational Database Service User Guide.

    This setting doesn't apply to RDS Custom.

  • :performance_insights_kms_key_id (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.

  • :performance_insights_retention_period (Integer) —

    The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

    This setting doesn't apply to RDS Custom.

  • :cloudwatch_logs_export_configuration (Types::CloudwatchLogsExportConfiguration) —

    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.

  • :processor_features (Array<Types::ProcessorFeature>) —

    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.

  • :use_default_processor_features (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.

  • :deletion_protection (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.

  • :max_allocated_storage (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.

  • :certificate_rotation_restart (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.

    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:

    This setting doesn't apply to RDS Custom.

  • :replica_mode (String) —

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

    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.

  • :enable_customer_owned_ip (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.

  • :aws_backup_recovery_point_arn (String) —

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
