Analyze AlloyDB 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 Cloud, 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 Cloud and subsequently analyzing AlloyDB data within Cognos Analytics.

NOTE: These instructions require Cognos Analytics 11.2.4 or higher

CData Connect Cloud 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 Cloud 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 Cloud. To work with AlloyDB data from Cognos Analytics, we start by creating and configuring a AlloyDB connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "AlloyDB" from the Add Connection panel
3. 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.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add AlloyDB 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 AlloyDB data from Cognos Analytics.

Connect to AlloyDB from Cognos Analytics

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

Live Access to AlloyDB Data for Analytics

Now you have a direct, cloud-to-cloud connection to live AlloyDB data from Cognos Analytics. You can create new visualizations, build reports, and more — without replicating AlloyDB data.
