IBM Informix MuleSoft Connector



Create a simple Mule Application that uses HTTP and SQL with the CData Mule Connector for IBM Informix to create a JSON endpoint for IBM Informix data.

The CData Mule Connector for IBM Informix connects IBM Informix data to Mule applications enabling read , write, update, and delete functionality with familiar SQL queries. The Connector allows users to easily create Mule Applications to backup, transform, report, and analyze IBM Informix data.

This article demonstrates how to use the CData Mule Connector for IBM Informix inside of a Mule project to create a Web interface for IBM Informix data. The application created allows you to request IBM Informix data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData Mule Connector to create a Web interface for the 200+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a CData IBM Informix Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties to connect to IBM Informix (see below). Once the connection is configured, click Test Connection to ensure the connectivity to IBM Informix.

    Set the following properties to connect to IBM Informix

    • Server: Set this to the name of the server running IBM Informix.
    • Port: Set this to the port the IBM Informix server is listening on.
    • Database: Set this to the name of the IBM Informix database.
    • User: Set this to the username of a user allowed to access the database.
    • Password: Set this to the password of a user allowed to access the database.
  6. Configure the CData IBM Informix Connector.
    1. Set the Operation to 'Select with Streaming'.
    2. Set the Query type to Dynamic.
    3. Set the SQL query to SELECT * FROM #[message.inboundProperties.'http.query.params'.get('table')] to parse the URL parameter table and use it as the target of the SELECT query. You can customize the query further by referencing other potential URL parameters.
  7. Add a Transform Message Component to the flow.
    1. Map the Payload from the input to the Map in the output.
    2. Set the Output script to the following to convert the payload to JSON:
      %dw 1.0
      %output application/json
      ---
      payload
              
  8. To view your IBM Informix data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default) and pass a table name as the table URL parameter: http://localhost:8081?table=Books
    The Books data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with IBM Informix data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the Mule Connector for IBM Informix and see the CData difference in your Mule Applications today.
