Vertica Integration with Datawatch Panopticon: Connection Guide

Applies to Vertica 8.0.x and earlier 


About Vertica Connection Guides

Vertica connection guides provide basic information about setting up connections to Vertica from software that our technology partners create. These documents provide guidance using one specific version of Vertica and one specific version of the third-party vendor’s software. Other versions of the third-party product may work with Vertica. However, other versions may not have been tested. This document provides guidance using the latest versions of Vertica and Datawatch Panopticon as of November, 2016.

Datawatch Panopticon Overview

Datawatch Panopticon along with Datawatch Monarch, allows for self-service data preparation and fast visualization. Datawatch is available for Windows as a 32-bit or 64-bit application. Datawatch Panopticon has a Vertica-named connection that uses the ODBC driver to connect to Vertica.

This document is based on the results of testing Vertica 8.0.x with Datawatch Panopticon 16.0.0 on a Windows 64-bit platform.

Download and Install Datawatch


Visit the Datawatch site to request a demo version of Datawatch Panopticon and download a trial version of the software. Follow the instructions from Datawatch.

To install Datawatch Panopticon, follow the instructions provided by Datawatch. Double-click the installer, and a series of prompts leads you through the installation process. The installer checks if your machine meets all the prerequisites required to install the application. If some prerequisites are not met, the installer attempts to install them. 

Download and Install Vertica Client Drivers

Before you can connect to Vertica using Datawatch Designer, you must download and install the Vertica client package. This package includes the ODBC driver that Datawatch Designer uses to connect to Vertica.

Download Vertica Client Driver

  1. Go to the Vertica Client Drivers page. 
  1. Download the version (32-bit or 64-bit) of theVertica client package that matches your operating system and Vertica server version.

Note Vertica drivers are forward compatible, so you can connect to the Vertica server using previous versions of the client. For more information, see Client Driver and Server Version Compatibility in the Vertica documentation.

Install Vertica Client Driver

As a Windows administrator, double-click the installer and follow the wizard to complete the installation process. You should only install the ODBC driver.

Note: If you use Datawatch Panopticon version 13.7 or later, you do not need to create a DSN. If you use an earlier version of Datawatch Panopticon, you must create a DSN.

For more information, see Creating an ODBC DSN for Windows Clients.
