HPCC ODBC Driver

The HPCC ODBC Driver is a powerful tool that allows you to connect with live HPCC Systems data, directly from any applications that support ODBC connectivity.

Access HPCC Systems like you would a database - query data through a standard ODBC Driver interface.



Create an ODBC connection to HPCC Systems in Informatica and browse and transfer HPCC Systems data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for HPCC Systems, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse HPCC Systems data in Informatica PowerCenter.

Connect to HPCC Systems as an ODBC Data Source

Information for connecting to HPCC Systems follows, along with different instructions for configuring a DSN in Windows and Linux environments.

To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

Set Cluster to the target cluster.

Windows

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.

Linux

If you are installing the CData ODBC Driver for HPCC Systems in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData HPCC Source] Driver = CData ODBC Driver for HPCC Systems Description = My Description URL = http://127.0.0.1:8510 User = test password = xA123456 Version = 1 Cluster = hthor

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a Linked Table to hpcc::test::orders Data

Follow the steps below to create a linked table, which enables you to access live hpcc::test::orders data.

Create the ODBC Connection

Follow the steps below to connect to HPCC Systems in Informatica PowerCenter:

  1. In the Informatica Developer tool connect to your repository and create a project.
  2. In the Connection Explorer pane, right-click and click Create a Connection.
  3. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select ODBC.
  4. In the Connection String property, enter the DSN.

NOTE: If you are working in a Linux operating system, set the Driver Manager for Linux property to unixODBC 2.3.x.

Create the HPCC Systems Data Object

After you have created an ODBC connection to HPCC Systems, you can now access HPCC Systems entities in Informatica. Follow the steps below to add hpcc::test::orders entities to your project.

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. In the wizard that is displayed, select the Relational Data Object option.
  3. Click the Browse button next to the Connection box and select the ODBC connection you created in the previous step.
  4. Select the option to create a data object from an existing resource and click the Browse button next to the Resource box.
  5. In the dialog that is displayed, clear the Show Default Schema Only option and expand the node for the ODBC connection. Select the entity that you want.

You can now browse the table in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

Create the Mapping

Follow the steps below to add the HPCC Systems source to a mapping:

  1. In the Object Explorer, right-click your project and then click New -> Mapping.
  2. Expand the node for the HPCC Systems connection and then drag the data object for the table onto the editor.
  3. In the dialog that appears, select the Read option.

Follow the steps below to map HPCC Systems columns to a flat file:

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
  3. In the properties for the HPCC Systems object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
  4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
  5. Click and drag to connect columns.

To transfer HPCC Systems data, right-click in the workspace and then click Run Mapping.
