Analyze Redshift Data in Cognos Analytics

IBM Watson®-powered Cognos Analytics lets you clean and connect your data and build visualizations. When paired with CData Connect Cloud, you get instant, real-time connectivity between your cloud data and Cognos Analytics for data management, visualization, analytics, and more. This article shows how to connect to Redshift in CData Connect Cloud and then analyze Redshift data in Cognos Analytics.

NOTE: These instructions require Cognos Analytics 11.2.4 or higher

CData Connect Cloud provides a pure cloud-to-cloud interface for Redshift, allowing you to analyze live Redshift data in Cognos — without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Redshift, leveraging server-side processing to quickly return the requested Redshift data.

Connect to Redshift in Connect Cloud

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Redshift" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Redshift.

   To connect to 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 the Server and Port values in the AWS Management Console:

   1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
   2. On the Clusters page, click the name of the cluster.
   3. On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Redshift Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Redshift data from Cognos Analytics.

Connect to Redshift in Cognos Analytics

The steps below outline connecting to CData Connect Cloud from Cognos Analytics to analyze live Redshift data.

Download the CData Connect Cloud JDBC Driver

1. Download and install the CData Connect Cloud JDBC Driver: https://www.cdata.com/cloud/clients/download.aspx#jdbc.
2. Copy the JAR file (cdata.jdbc.connect.jar) from the installation directory (e.g., C:\Program Files\CData\JDBC Driver for CData Connect\lib) to the "drivers" folder in your Cognos Analytics installation directory.

Configure the Connection to CData Connect Cloud

1. Open IBM Cognos and navigate to Manage > Data server connections.
2. Click the icon to add a data server.
3. Select CData Connect Cloud.
4. Set JDBC URL to the appropriate connection string. For example: jdbc:connect://AuthScheme=Basic;
5. Set Driver class name to "cdata.jdbc.connect.ConnectDriver"
6. Create and store authenticate credentials by selecting an authentication method
   • Set Username to your CData Connect Cloud username (e.g., user@mydomain.com)
   • Set Password to the PAT you previously generated.
7. Click Test connection to confirm that the connection succeeds.

At this point, you are ready to analyze and visualize Redshift data in Cognos Analytics. For more information about using Cognos Analytics, please refer to the Cognos Analytics documentation.
