getDbParameterGroupName
The name of an existing DB parameter group or a reference to an AWS::RDS::DBParameterGroup resource created in the template.To list all of the available DB parameter group names, use the following command:
aws rds describe-db-parameter-groups --query "DBParameterGroups[].DBParameterGroupName" --output textIf any of the data members of the referenced parameter group are changed during an update, the DB instance might need to be restarted, which causes some interruption. If the parameter group contains static parameters, whether they were changed or not, an update triggers a reboot.
If you don't specify a value for
DBParameterGroupNameproperty, the default DB parameter group for the specified engine and engine version is used.Returns union: either

getDbSecurityGroups
A list of the DB security groups to assign to the DB instance.The list can include both the name of existing DB security groups or references to AWS::RDS::DBSecurityGroup resources created in the template.
If you set DBSecurityGroups, you must not set VPCSecurityGroups, and vice versa. Also, note that the DBSecurityGroups property exists only for backwards compatibility with older regions and is no longer recommended for providing security information to an RDS DB instance. Instead, use VPCSecurityGroups.
If you specify this property, AWS CloudFormation sends only the following properties (if specified) to Amazon RDS during create operations:
AllocatedStorageAutoMinorVersionUpgradeAvailabilityZoneBackupRetentionPeriodCharacterSetNameDBInstanceClassDBNameDBParameterGroupNameDBSecurityGroupsDBSubnetGroupNameEngineEngineVersionIopsLicenseModelMasterUsernameMasterUserPasswordMultiAZOptionGroupNamePreferredBackupWindowPreferredMaintenanceWindow
All other properties are ignored. Specify a virtual private cloud (VPC) security group if you want to submit other properties, such as
StorageType,StorageEncrypted, orKmsKeyId. If you're already using theDBSecurityGroupsproperty, you can't use these other properties by updating your DB instance to use a VPC security group. You must recreate the DB instance.- See Also:
-
getDbSnapshotIdentifier
The name or Amazon Resource Name (ARN) of the DB snapshot that's used to restore the DB instance.If you're restoring from a shared manual DB snapshot, you must specify the ARN of the snapshot.
By specifying this property, you can create a DB instance from the specified DB snapshot. If the
DBSnapshotIdentifierproperty is an empty string or theAWS::RDS::DBInstancedeclaration has noDBSnapshotIdentifierproperty, AWS CloudFormation creates a new database. If the property contains a value (other than an empty string), AWS CloudFormation creates a database from the specified snapshot. If a snapshot with the specified name doesn't exist, AWS CloudFormation can't create the database and it rolls back the stack.Some DB instance properties aren't valid when you restore from a snapshot, such as the
MasterUsernameandMasterUserPasswordproperties, and the point-in-time recovery propertiesRestoreTimeandUseLatestRestorableTime. For information about the properties that you can specify, see theRestoreDBInstanceFromDBSnapshotaction in the Amazon RDS API Reference .After you restore a DB instance with a
DBSnapshotIdentifierproperty, you must specify the sameDBSnapshotIdentifierproperty for any future updates to the DB instance. When you specify this property for an update, the DB instance is not restored from the DB snapshot again, and the data in the database is not changed. However, if you don't specify theDBSnapshotIdentifierproperty, an empty DB instance is created, and the original DB instance is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB instance is restored from the specifiedDBSnapshotIdentifierproperty, and the original DB instance is deleted.If you specify the
DBSnapshotIdentifierproperty to restore a DB instance (as opposed to specifying it for DB instance updates), then don't specify the following properties:CharacterSetNameDBClusterIdentifierDBNameKmsKeyIdMasterUsernameMasterUserPasswordPromotionTierSourceDBInstanceIdentifierSourceRegionStorageEncrypted(for an unencrypted snapshot)Timezone
Amazon Aurora
Not applicable. Snapshot restore is managed by the DB cluster.
- See Also:
-
getDbSubnetGroupName
A DB subnet group to associate with the DB instance.If you update this value, the new subnet group must be a subnet group in a new VPC.
If you don't specify a DB subnet group, RDS uses the default DB subnet group if one exists. If a default DB subnet group does not exist, and you don't specify a
DBSubnetGroupName, the DB instance fails to launch.For more information about using Amazon RDS in a VPC, see Amazon VPC and Amazon RDS in the Amazon RDS User Guide .
This setting doesn't apply to Amazon Aurora DB instances. The DB subnet group is managed by the DB cluster. If specified, the setting must match the DB cluster setting.
Returns union: either
StringorIDBSubnetGroupRef- See Also:
-
getDbSystemId
The Oracle system identifier (SID), which is the name of the Oracle database instance that manages your database files.In this context, the term "Oracle database instance" refers exclusively to the system global area (SGA) and Oracle background processes.

The number of I/O operations per second (IOPS) that the database provisions.The value must be equal to or greater than 1000.
If you specify this property, you must follow the range of allowed ratios of your requested IOPS rate to the amount of storage that you allocate (IOPS to allocated storage). For example, you can provision an Oracle database instance with 1000 IOPS and 200 GiB of storage (a ratio of 5:1), or specify 2000 IOPS with 200 GiB of storage (a ratio of 10:1). For more information, see Amazon RDS Provisioned IOPS Storage to Improve Performance in the Amazon RDS User Guide .
If you specify
io1for theStorageTypeproperty, then you must also specify theIopsproperty.Constraints:
- For RDS for Db2, MariaDB, MySQL, Oracle, and PostgreSQL - Must be a multiple between .5 and 50 of the storage amount for the DB instance.

If you specify this property, you must set the StorageEncrypted property to true.
If you specify the
SourceDBInstanceIdentifierorSourceDbiResourceIdproperty, don't specify this property. The value is inherited from the source DB instance, and if the DB instance is encrypted, the specifiedKmsKeyIdproperty is used. However, if the source DB instance is in a different AWS Region, you must specify a KMS key ID.If you specify the
SourceDBInstanceAutomatedBackupsArnproperty, don't specify this property. The value is inherited from the source DB instance automated backup, and if the automated backup is encrypted, the specifiedKmsKeyIdproperty is used.If you create an encrypted read replica in a different AWS Region, then you must specify a KMS key for the destination AWS Region. KMS encryption keys are specific to the region that they're created in, and you can't use encryption keys from one region in another region.
If you specify the
DBSnapshotIdentifierproperty, don't specify this property. TheStorageEncryptedproperty value is inherited from the snapshot. If the DB instance is encrypted, the specifiedKmsKeyIdproperty is also inherited from the snapshot.If you specify
DBSecurityGroups, AWS CloudFormation ignores this property. To specify both a security group and this property, you must use a VPC security group. For more information about Amazon RDS and VPC, see Using Amazon RDS with Amazon VPC in the Amazon RDS User Guide .Amazon Aurora

getSourceDbInstanceIdentifier
If you want to create a read replica DB instance, specify the ID of the source DB instance.Each DB instance can have a limited number of read replicas. For more information, see Working with Read Replicas in the Amazon RDS User Guide .
For information about constraints that apply to DB instance identifiers, see Naming constraints in Amazon RDS in the Amazon RDS User Guide .
The
SourceDBInstanceIdentifierproperty determines whether a DB instance is a read replica. If you remove theSourceDBInstanceIdentifierproperty from your template and then update your stack, AWS CloudFormation promotes the read replica to a standalone DB instance.If you specify the
UseLatestRestorableTimeorRestoreTimeproperties in conjunction with theSourceDBInstanceIdentifierproperty, RDS restores the DB instance to the requested point in time, thereby creating a new DB instance.- If you specify a source DB instance that uses VPC security groups, we recommend that you specify the
VPCSecurityGroupsproperty. If you don't specify the property, the read replica inherits the value of theVPCSecurityGroupsproperty from the source DB when you create the replica. However, if you update the stack, AWS CloudFormation reverts the replica'sVPCSecurityGroupsproperty to the default value because it's not defined in the stack's template. This change might cause unexpected issues. - Read replicas don't support deletion policies. AWS CloudFormation ignores any deletion policy that's associated with a read replica.
- If you specify
SourceDBInstanceIdentifier, don't specify theDBSnapshotIdentifierproperty. You can't create a read replica from a snapshot. - Don't set the
BackupRetentionPeriod,DBName,MasterUsername,MasterUserPassword, andPreferredBackupWindowproperties. The database attributes are inherited from the source DB instance, and backups are disabled for read replicas. - If the source DB instance is in a different region than the read replica, specify the source region in
SourceRegion, and specify an ARN for a valid DB instance inSourceDBInstanceIdentifier. For more information, see Constructing a Amazon RDS Amazon Resource Name (ARN) in the Amazon RDS User Guide . - For DB instances in Amazon Aurora clusters, don't specify this property. Amazon RDS automatically assigns writer and reader DB instances.

getVpcSecurityGroups
A list of the VPC security group IDs to assign to the DB instance.The list can include both the physical IDs of existing VPC security groups and references to AWS::EC2::SecurityGroup resources created in the template.
If you plan to update the resource, don't specify VPC security groups in a shared VPC.
If you set
VPCSecurityGroups, you must not setDBSecurityGroups, and vice versa.You can migrate a DB instance in your stack from an RDS DB security group to a VPC security group, but keep the following in mind:
- You can't revert to using an RDS security group after you establish a VPC security group membership.
- When you migrate your DB instance to VPC security groups, if your stack update rolls back because the DB instance update fails or because an update fails in another AWS CloudFormation resource, the rollback fails because it can't revert to an RDS security group.
- To use the properties that are available when you use a VPC security group, you must recreate the DB instance. If you don't, AWS CloudFormation submits only the property values that are listed in the
DBSecurityGroupsproperty.
To avoid this situation, migrate your DB instance to using VPC security groups only when that is the only change in your stack template.
Amazon Aurora
Not applicable. The associated list of EC2 VPC security groups is managed by the DB cluster. If specified, the setting must match the DB cluster setting.
