Analyze Redshift Data in Cognos Analytics

Cognos Analytics, powered by IBM Watson®, empowers users to cleanse and establish connections with their data while creating visualizations. When integrated with CData Connect AI, users gain immediate, real-time connectivity between cloud-based data sources and Cognos Analytics, facilitating data management, visualization, analytics, and more. This article provides step-by-step guidance on connecting to Redshift via CData Connect AI and subsequently analyzing Redshift data within Cognos Analytics.

NOTE: These instructions require Cognos Analytics 11.2.4 or higher

CData Connect AI offers a dedicated cloud-to-cloud interface for Redshift, enabling users to perform real-time analysis on Redshift data within Cognos without the need to replicate data to a natively supported database. Equipped with built-in optimized data processing capabilities, CData Connect AI efficiently directs all supported SQL operations, including filters and JOINs, directly to Redshift. This harnesses server-side processing to promptly provide the requested Redshift data.

Configure Redshift Connectivity for Cognos Analytics

Connectivity to Redshift from Cognos Analytics is made possible through CData Connect AI. To work with Redshift data from Cognos Analytics, we start by creating and configuring a Redshift connection.

1. Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection

2. Select "Redshift" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to Redshift.

   To connect to Redshift, set the following:

   • : Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
   • : Set this to the port of the cluster.
   • : Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
   • : Set this to the username you want to use to authenticate to the Server.
   • : Set this to the password you want to use to authenticate to the Server.

   You can obtain the and 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 Save & Test
5. Navigate to the Permissions tab in the Add Redshift Connection page and update the User-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
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 and a PAT generated, you are ready to connect to Redshift data from Cognos Analytics.

Connect to Redshift from Cognos Analytics

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

Download and install the CData Connect AI JDBC driver

1. Open the Integrations page of CData Connect AI.
2. Search for and select JDBC.
3. Download and run the setup file.
4. When the installation is complete, 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 AI

1. Open IBM Cognos and navigate to Manage > Data server connections.
2. Click the icon to add a data server.
3. Select CData Connect AI.
4. Set JDBC URL to the appropriate connection string. For example:

    jdbc:connect:AuthScheme=Basic;user=username;password=PAT;
    

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 AI username (e.g., [email protected])
   • Set Password to the PAT you previously generated.
7. Click Test connection to confirm that the connection succeeds. 👁 Connecting to CData Connect AI from Cognos Analytics
   

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.
