Analyze Vertica 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 Vertica via CData Connect AI and subsequently analyzing Vertica 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 Vertica, enabling users to perform real-time analysis on Vertica 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 Vertica. This harnesses server-side processing to promptly provide the requested Vertica data.

Configure Vertica Connectivity for Cognos Analytics

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

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

2. Select "Vertica" from the Add Connection panel

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

   Set the following connection properties to connect with Vertica.

   • Server: Enter the host name or the IP address of the server that hosts the Vertica database.
   • Port: Enter the port number for your Vertica database. The default port is 5433.
   • User: Enter the username that you use to authenticate to the Vertica database.
   • Password: Enter the password that you use to authenticate to the Vertica database.
   • Database: Enter the name of the database hosted on your Vertica server.
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Vertica Connection page and update the User-based 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.
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 Vertica data from Cognos Analytics.

Connect to Vertica from Cognos Analytics

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

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