Description

Creates a replication task using the specified parameters.

Parameters

-CdcStartPosition <String>
Indicates when you want a change data capture (CDC) operation to start. Use either CdcStartPosition or CdcStartTime to specify when you want a CDC operation to start. Specifying both values results in an error. The value can be in date, checkpoint, or LSN/SCN format.Date Example: --cdc-start-position “2018-03-08T12:12:12”Checkpoint Example: --cdc-start-position "checkpoint:V1#27#mysql-bin-changelog.157832:1975:-1:2002:677883278264080:mysql-bin-changelog.157832:1876#0#0#*#0#93"LSN Example: --cdc-start-position “mysql-bin-changelog.000024:373”When you use this task setting with a source PostgreSQL database, a logical replication slot should already be created and associated with the source endpoint. You can verify this by setting the slotName extra connection attribute to the name of this logical replication slot. For more information, see Extra Connection Attributes When Using PostgreSQL as a Source for DMS.

-ResourceIdentifier <String>
A friendly name for the resource identifier at the end of the EndpointArn response parameter that is returned in the created Endpoint object. The value for this parameter can have up to 31 characters. It can contain only ASCII letters, digits, and hyphen ('-'). Also, it can't end with a hyphen or contain two consecutive hyphens, and can only begin with a letter, such as Example-App-ARN1. For example, this value might result in the EndpointArn value arn:aws:dms:eu-west-1:012345678901:rep:Example-App-ARN1. If you don't specify a ResourceIdentifier value, DMS generates a default identifier value for the end of EndpointArn.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'ReplicationTask'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.DatabaseMigrationService.Model.CreateReplicationTaskResponse). Specifying the name of a property of type Amazon.DatabaseMigrationService.Model.CreateReplicationTaskResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.

AliasesTableMappings
-Tag <Tag[]>
One or more tags to be assigned to the replication task. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False

Outputs

Amazon.DatabaseMigrationService.Model.ReplicationTask or Amazon.DatabaseMigrationService.Model.CreateReplicationTaskResponse
This cmdlet returns an Amazon.DatabaseMigrationService.Model.ReplicationTask object. The service call response (type Amazon.DatabaseMigrationService.Model.CreateReplicationTaskResponse) can be returned by specifying '-Select *'.

Examples

Example 1

New-DMSReplicationTask -ReplicationInstanceArn "arn:aws:dms:us-east-1:123456789012:rep:EXAMPLE66XFJUWATDJGBEXAMPLE"`
  -CdcStartTime "2019-08-08T12:12:12"`
  -CdcStopPosition "server_time:2019-08-09T12:12:12"`
  -MigrationType "full-load-and-cdc"`
  -ReplicationTaskIdentifier "task1"`
  -ReplicationTaskSetting ""`
  -SourceEndpointArn "arn:aws:dms:us-east-1:123456789012:endpoint:EXAMPLEW5UANC7Y3P4EEXAMPLE"`
  -TableMapping "file:////home/testuser/table-mappings.json"`
  -Tag @{"Key"="Stage";"Value"="Test"}`
  -TargetEndpointArn "arn:aws:dms:us-east-1:123456789012:endpoint:EXAMPLEJZASXWHTWCLNEXAMPLE"
This example creates a new AWS Database Migration Service replication task that uses CdcStartTime instead of CdcStartPosition. The MigrationType is set to "full-load-and-cdc", meaning the target table must be empty.
    The new task is tagged with a tag that has a key of Stage and a key value of Test. For more information about the values used by this cmdlet, see Creating a Task (https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.Creating.html) in the AWS Database Migration Service User Guide.
