Use CData Connect AI to connect to AlloyDB Data from Cognos Analytics and analyze live AlloyDB data.

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

Configure AlloyDB Connectivity for Cognos Analytics

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

  1. Log into Connect AI, click Sources, and then click Add Connection
  2. 👁 Adding a Connection
  3. Select "AlloyDB" from the Add Connection panel
  4. 👁 Selecting a data source
  5. Enter the necessary authentication properties to connect to AlloyDB.

    The following connection properties are usually required in order to connect to AlloyDB.

    • Server: The host name or IP of the server hosting the AlloyDB database.
    • User: The user which will be used to authenticate with the AlloyDB server.
    • Password: The password which will be used to authenticate with the AlloyDB server.

    You can also optionally set the following:

    • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
    • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

    Authenticating with Standard Authentication

    Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

    No further action is required to leverage Standard Authentication to connect.

    Authenticating with pg_hba.conf Auth Schemes

    There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

    Find instructions about authentication setup on the AlloyDB Server here.

    Authenticating with MD5 Authentication

    This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

    Authenticating with SASL Authentication

    This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

    Authenticating with Kerberos

    The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos. 👁 Configuring a connection (Salesforce is shown)

  6. Click Save & Test
  7. Navigate to the Permissions tab in the Add AlloyDB 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 AlloyDB data from Cognos Analytics.

Connect to AlloyDB from Cognos Analytics

The steps below outline connecting to CData Connect AI from Cognos Analytics to analyze live AlloyDB 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 AlloyDB data in Cognos Analytics. For more information about using Cognos Analytics, please refer to the Cognos Analytics documentation.
