Replicate SAP HANA Data to Multiple Databases



Replicate SAP HANA data to disparate databases with a point-and-click configuration.

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live SAP HANA data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote SAP HANA data from Windows.

Configure Replication Destinations

Using CData Sync, you can replicate SAP HANA data to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

For each destination database:

  1. Click Add Connection.
  2. Select a destination. In this article, we use SQLite.
  3. Enter the necessary connection properties. To replicate SAP HANA to a SQLite database, enter a file path in the Data Source box.
  4. Click Test Connection to ensure that the connection is configured properly.
  5. Click Save Changes.

Configure the SAP HANA Connection

You can configure a connection to SAP HANA from the Connections tab. To add a connection to your SAP HANA account, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select a source (SAP HANA).
  3. Configure the connection properties.

    Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

  4. Click Connect to ensure that the connection is configured properly.
  5. Click Save Changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the SAP HANA API. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

The statement below caches and incrementally updates a table of SAP HANA data:

REPLICATE Buckets;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple SAP HANA accounts into the same database:

  • Use a different table prefix in the REPLICATE SELECT statement:

    REPLICATE PROD_Buckets SELECT * FROM Buckets;
  • Alternatively, use a different schema:

    REPLICATE PROD.Buckets SELECT * FROM Buckets;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your SAP HANA data to disparate on-premises, cloud-based, and other databases.
