Create an SAP BusinessObjects Universe on the CData ODBC Driver for RabbitMQ

This article shows how to create and publish an SAP BusinessObjects universe on the CData ODBC Driver for RabbitMQ. You will connect to RabbitMQ data from the Information Design Tool as well as the Web Intelligence tool.

Connect to RabbitMQ as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

About RabbitMQ Management HTTP API

RabbitMQ is an open-source message broker that supports multiple messaging protocols. The RabbitMQ Management HTTP API provides HTTP-based access to management and monitoring data for a RabbitMQ server. The API exposes information about virtual hosts, exchanges, queues, bindings, connections, channels, consumers, users, permissions, policies, and cluster-wide statistics.

The Management plugin must be enabled on the RabbitMQ server for the HTTP API to be available. By default, the management interface listens on port 15672.

Using Basic Authentication

RabbitMQ Management HTTP API uses HTTP Basic authentication. You must supply the username and password of a RabbitMQ management user.

To enable access to the management API:

1. Ensure the RabbitMQ Management plugin is enabled on your server (rabbitmq-plugins enable rabbitmq_management).
2. Use an existing management user or create one with the appropriate management tag (management, policymaker, monitoring, or administrator).
3. Note the full base URL of your RabbitMQ Management HTTP API (e.g., http://localhost:15672).

After configuring your RabbitMQ server, set the following connection properties to connect:

• AuthScheme: Set this to Basic.
• URL: Set this to the base URL of your RabbitMQ Management HTTP API (e.g., http://localhost:15672).
• User: Set this to your RabbitMQ management username (e.g., guest).
• Password: Set this to your RabbitMQ management password.

Example connection string:

Profile=C:\profiles\RabbitMQ.apip;AuthScheme=Basic;URL=http://localhost:15672;User=guest;Password=guest;

Available Tables

The RabbitMQ profile provides access to the following tables:

• Overview - Cluster-wide statistics and information about the RabbitMQ node
• Nodes - Information about individual nodes in the RabbitMQ cluster
• NodeMemory - Detailed memory usage breakdown for a specific cluster node
• Connections - List of all open AMQP connections to the broker
• Channels - List of all open AMQP channels across all connections
• Consumers - List of all consumers registered across all queues
• Exchanges - List of exchanges declared across all virtual hosts
• Queues - List of queues declared across all virtual hosts
• Bindings - List of all bindings between exchanges and queues
• VirtualHosts - List of virtual hosts configured on the broker
• VhostPermissions - User permissions within a specific virtual host
• Users - List of all RabbitMQ users
• Permissions - Permission records for all users across all virtual hosts
• TopicPermissions - Topic-level permission records for all users
• Policies - List of policies applied to queues and exchanges in virtual hosts
• OperatorPolicies - List of operator policies applied to queues in virtual hosts
• Parameters - List of component parameters (e.g., federation, shovel) per virtual host
• GlobalParameters - List of global parameters that apply across all virtual hosts
• VhostLimits - Resource limits configured for specific virtual hosts
• UserLimits - Resource limits configured for specific users
• FeatureFlags - List of feature flags and their enabled/disabled state on the node
• DeprecatedFeatures - List of deprecated features and their usage state
• AuthAttempts - Authentication attempt statistics for the node
• ClusterName - The name of the RabbitMQ cluster
• WhoAmI - Information about the currently authenticated management user
• ExchangeBindingsSource - Bindings for which a specific exchange is the source
• ExchangeBindingsDestination - Bindings for which a specific exchange is the destination
• QueueBindings - Bindings for a specific queue within a virtual host

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Create an ODBC Connection to RabbitMQ Data

This section shows how to create a connection to the RabbitMQ ODBC data source in the Information Design Tool. After you create a connection, you can analyze data or create a BusinessObjects universe.

1. Right-click your project and click New -> New Relational Connection.

2. In the wizard that is displayed, enter a name for the connection.

3. Select Generic -> Generic ODBC datasource -> ODBC Drivers and select the DSN.

4. Finish the wizard with the default values for connection pooling and custom parameters.

Analyze RabbitMQ Data in the Information Design Tool

In the Information Design Tool, you can use both published and local ODBC connections to browse and query data.

1. In the Local Projects view, double-click the connection (the .cnx file) to open the RabbitMQ data source.

2. On the Show Values tab, you can load table data and enter SQL queries. To view table data, expand the node for the table, right-click the table, and click Show Values. Values will be displayed in the Raw Data tab.

3. On the Analysis tab, you can drag and drop columns onto the axes of a chart.

Publish the Local Connection

To publish the universe to the CMS, you additionally need to publish the connection.

1. In the Local Projects view, right-click the connection and click Publish Connection to a Repository.

2. Enter the host and port of the repository and connection credentials.

3. Select the folder where the connection will be published.

4. In the success dialog that results, click Yes to create a connection shortcut.

Create a Universe on the ODBC Driver for RabbitMQ

You can follow the steps below to create a universe on the ODBC driver for RabbitMQ. The universe in this example will be published to a repository, so it uses the published connection created in the previous step.

1. In the Information Design Tool, click File->New Universe.

2. Select your project.

3. Select the option to create the universe on a relational data source.

4. Select the shortcut to the published connection.

5. Enter a name for the Data Foundation.

6. Import tables and columns that you want to access as objects.

7. Enter a name for the Business Layer.

Publish the Universe

You can follow the steps below to publish the universe to the CMS.

1. In the Local Projects view, right-click the business layer and click Publish -> To a Repository.

2. In the Publish Universe dialog, enter any integrity checks before importing.

3. Select or create a folder on the repository where the universe will be published.

Query RabbitMQ Data in Web Intelligence

You can use the published universe to connect to RabbitMQ in Web Intelligence.

1. Open Web Intelligence from the BusinessObjects launchpad and create a new document.

2. Select the Universe option for the data source.

3. Select the RabbitMQ universe. This opens a Query Panel. Drag objects to the Result Objects pane to use them in the query.
