Automated Continuous Oracle Replication to Amazon Redshift

Use CData Sync for automated, continuous, customizable Oracle replication to Amazon Redshift.

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Oracle 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 Oracle data to Amazon Redshift. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select Amazon Redshift as a destination.
  3. Enter the necessary connection properties. To connect to Amazon Redshift, set the following:
    • Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
    • Port: Set this to the port of the cluster.
    • Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
    • 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.

    You can obtain these values 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.

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

Configure the Oracle Connection

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

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

    To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

    • Port: The port used to connect to the server hosting the Oracle database.
    • User: The user Id provided for authentication with the Oracle database.
    • Password: The password provided for authentication with the Oracle database.
    • Service Name: The service name of the Oracle database.
  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 the Transform feature to customize your replication. The Transform feature allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. To customize your replication, click the Transform button in the Tables section and customize the replication.

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 15 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 Oracle data to Amazon Redshift.
