Using a SAP ASE database as a target for AWS Database Migration Service

You can migrate data to SAP Adaptive Server Enterprise (ASE)–formerly known as Sybase–databases using AWS DMS, either from any of the supported database sources.

SAP ASE versions 15, 15.5, 15.7, 16 and later are supported.

Prerequisites for using a SAP ASE database as a target for AWS Database Migration Service

Before you begin to work with a SAP ASE database as a target for AWS DMS, make sure that you have the following prerequisites:

• Provide SAP ASE account access to the AWS DMS user. This user must have read/write privileges in the SAP ASE database.

• In some cases, you might replicate to SAP ASE version 15.7 installed on an Amazon EC2 instance on Microsoft Windows that is configured with non-Latin characters (for example, Chinese). In such cases, AWS DMS requires SAP ASE 15.7 SP121 to be installed on the target SAP ASE machine.

Limitations when using a SAP ASE database as a target for AWS DMS

The following limitations apply when using an SAP ASE database as a target for AWS DMS:

• AWS DMS doesn't support tables that include fields with the following data types. Replicated columns with these data types show as null.

  • User-defined type (UDT)

Endpoint settings when using SAP ASE as a target for AWS DMS

You can use endpoint settings to configure your SAP ASE target database similar to using extra connection attributes. You specify the settings when you create the target endpoint using the AWS DMS console, or by using the create-endpoint command in the AWS CLI, with the --sybase-settings '{"EndpointSetting": "value", ...}' JSON syntax.

The following table shows the endpoint settings that you can use with SAP ASE as a target.

Name	Description
Driver	Set this attribute if you want to use TLS for versions of ASE 15.7 and later. Default value: Adaptive Server Enterprise Example: driver=Adaptive Server Enterprise 16.03.06; Valid values: Adaptive Server Enterprise 16.03.06
AdditionalConnectionProperties	Any additional ODBC connection parameters that you want to specify.
