Automated Continuous DB2 Replication to Amazon Redshift

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live DB2 data into your Amazon Redshift instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

Configure Amazon Redshift as a Replication Destination

Using CData Sync, you can replicate DB2 data to Amazon Redshift. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection. 👁 Add a new connection.
   
2. Select the Destinations tab and locate the Amazon Redshift connector. 👁 Configure a Destination connection to Amazon Redshift.
   
3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the Amazon Redshift connector. For more information about installing new connectors, see Connections in the Help documentation.
4. To connect to Amazon Redshift, set the following connection properties:
   • Connection Name: Enter a connection name of your choice for the Amazon Redshift connection.
   • Server: Enter the host name or IP of the server that hosts the Amazon Redshift database (for example, example.us-west-2.redshift.amazonaws.com).
   • Database: Enter the name of the database that you create for your Amazon Redshift cluster.
   • AuthScheme: Select the authentication scheme.
   • User: Set this to the username you want to use to authenticate to the Server.
   • Password: Set this to the password you want to use to authenticate to the Server.
   • Port: Set this to the port of the cluster.

   You can obtain these values in the AWS Management Console:

   1. Open the Amazon Redshift console.
   2. On the Clusters page, click the name of the cluster.
   3. On the Configuration tab, obtain the properties from the Cluster Database Properties section. The connection property values will be the same as the values set in the ODBC URL.
👁 Enter the connection details.

5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to Amazon Redshift and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

👁 Add a label.

In this article, we will demonstrate how to load DB2 data into Amazon Redshift and utilize it as a destination.

Configure the DB2 Connection

You can configure a connection to DB2 from the Connections tab. To add a connection to your DB2 account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (DB2).
3. Configure the connection properties.
   
   

   Set the following properties to connect to DB2:

   • Server: Set this to the name of the server running DB2.
   • Port: Set this to the port the DB2 server is listening on.
   • Database: Set this to the name of the DB2 database.
   • User: Set this to the username of a user allowed to access the database.
   • Password: Set this to the password of a user allowed to access the database.

   You will also need to install the corresponding DB2 driver:

   • Windows: Install the IBM Data Server Provider for .NET.

     On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

   • Java: Install the IBM Data Server Driver for JDBC.

     In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

4. Click Connect to DB2 to ensure that the connection is configured properly.
5. Click Save & Test to save the 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.

👁 Select Source and Destination connections for the replication.

Replicate Entire Tables

To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of DB2 tables you wish to replicate into Amazon Redshift, and click Add Tasks again.

👁 Choose entire tables to replicate (Salesforce is shown).

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries. 👁 Configure a replication Transform.

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.

👁 Schedule your job to run automatically.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your DB2 data to Amazon Redshift.

Run the Replication Job

Once all the required configurations are made for the job, select the DB2 table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.

👁 Run the job.
