Access Oracle SCM Data in Mule Applications Using the CData JDBC Driver

The CData JDBC Driver for Oracle SCM connects Oracle SCM data to Mule applications enabling read functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Oracle SCM data.

This article demonstrates how to use the CData JDBC Driver for Oracle SCM inside of a Mule project to create a Web interface for Oracle SCM data. The application created allows you to request Oracle SCM data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver 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 Database Select Connector to the same flow, after the HTTP Connector.
5. Create a new Connection (or edit an existing one) and configure the properties.
   • Set Connection to "Generic Connection"
   • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.oraclescm.jar).
   • Set the URL to the connection string for Oracle SCM

     The following connection properties are required to connect to Oracle SCM data.

     • Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
     • User: The username of your Oracle Cloud service account.
     • Password: The password of your Oracle Cloud service account.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Oracle SCM JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.oraclescm.jar

     Fill in the connection properties and copy the connection string to the clipboard.

   • Set the Driver class name to cdata.jdbc.oraclescm.OracleSCMDriver.
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request Oracle SCM data. For example: SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'
7. Add a Transform Message Component to the flow.
8. Set the Output script to the following to convert the payload to JSON:

   %dw 2.0
   output application/json
   ---
   payload
           

9. To view your Oracle SCM data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Oracle SCM 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 Oracle SCM 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 JDBC Driver for Oracle SCM and see the CData difference in your Mule Applications today.
