AWS::DMS::Endpoint MicrosoftSqlServerSettings

Provides information that defines a Microsoft SQL Server endpoint. This information includes the output format of records applied to the endpoint and details of transaction and control table data information. For information about other available settings, see Extra connection attributes when using SQL Server as a source for Amazon DMS and Extra connection attributes when using SQL Server as a target for Amazon DMS in the Amazon Database Migration Service User Guide.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "BcpPacketSize" : Integer,
  "ControlTablesFileGroup" : String,
  "DatabaseName" : String,
  "ForceLobLookup" : Boolean,
  "Password" : String,
  "Port" : Integer,
  "QuerySingleAlwaysOnNode" : Boolean,
  "ReadBackupOnly" : Boolean,
  "SafeguardPolicy" : String,
  "SecretsManagerAccessRoleArn" : String,
  "SecretsManagerSecretId" : String,
  "ServerName" : String,
  "TlogAccessMode" : String,
  "TrimSpaceInChar" : Boolean,
  "UseBcpFullLoad" : Boolean,
  "Username" : String,
  "UseThirdPartyBackupDevice" : Boolean
}

Properties

BcpPacketSize

The maximum size of the packets (in bytes) used to transfer data using BCP.

Required: No

Type: Integer

Update requires: No interruption

ControlTablesFileGroup

Specifies a file group for the Amazon DMS internal tables. When the replication task starts, all the internal Amazon DMS control tables (awsdms_ apply_exception, awsdms_apply, awsdms_changes) are created for the specified file group.

Required: No

Type: String

Update requires: No interruption

DatabaseName

Database name for the endpoint.

Required: No

Type: String

Update requires: No interruption

ForceLobLookup

Forces LOB lookup on inline LOB.

Required: No

Type: Boolean

Update requires: No interruption

Password

Endpoint connection password.

Required: No

Type: String

Update requires: No interruption

Port

Endpoint TCP port.

Required: No

Type: Integer

Update requires: No interruption

QuerySingleAlwaysOnNode

Cleans and recreates table metadata information on the replication instance when a mismatch occurs. An example is a situation where running an alter DDL statement on a table might result in different information about the table cached in the replication instance.

Required: No

Type: Boolean

Update requires: No interruption

ReadBackupOnly

When this attribute is set to Y, Amazon DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

Required: No

Type: Boolean

Update requires: No interruption

SafeguardPolicy

Use this attribute to minimize the need to access the backup log and enable Amazon DMS to prevent truncation using one of the following two methods.

Start transactions in the database: This is the default method. When this method is used, Amazon DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

Exclusively use sp_repldone within a single task: When this method is used, Amazon DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one Amazon DMS task can access the database at any given time. Therefore, if you need to run parallel Amazon DMS tasks against the same database, use the default method.

Required: No

Type: String

Update requires: No interruption

SecretsManagerAccessRoleArn

The full Amazon Resource Name (ARN) of the IAM role that specifies Amazon DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Secrets Manager secret that allows access to the SQL Server endpoint.

Note

You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both.

For more information on creating this SecretsManagerSecret, the corresponding SecretsManagerAccessRoleArn, and the SecretsManagerSecretId that is required to access it, see Using secrets to access Amazon Database Migration Service resources in the Amazon Database Migration Service User Guide.

Required: No

Type: String

Update requires: No interruption

SecretsManagerSecretId

The full ARN, partial ARN, or display name of the SecretsManagerSecret that contains the MicrosoftSQLServer endpoint connection details.

Required: No

Type: String

Update requires: No interruption

ServerName

Fully qualified domain name of the endpoint. For an Amazon RDS SQL Server instance, this is the output of DescribeDBInstances, in the Endpoint.Address field.

Required: No

Type: String

Update requires: No interruption

TlogAccessMode

Indicates the mode used to fetch CDC data.

Required: No

Type: String

Allowed values: BackupOnly | PreferBackup | PreferTlog | TlogOnly

Update requires: No interruption

TrimSpaceInChar

Use the TrimSpaceInChar source endpoint setting to right-trim data on CHAR and NCHAR data types during migration. Setting TrimSpaceInChar does not left-trim data. The default value is true.

Required: No

Type: Boolean

Update requires: No interruption

UseBcpFullLoad

Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option.

Required: No

Type: Boolean

Update requires: No interruption

Username

Endpoint connection user name.

Required: No

Type: String

Update requires: No interruption

UseThirdPartyBackupDevice

When this attribute is set to Y, DMS processes third-party transaction log backups if they are created in native format.

Required: No

Type: Boolean

Update requires: No interruption
