Vertica Integration with Attunity Replicate: Connection Guide

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 version of Vertica and one version of the third party vendor’s software. Other versions of the third-party product may work with Vertica. However, we may not have tested those other versions.

Download and Install the Vertica Client Drivers

Before you can connect to Vertica using Attunity Replicate you must install the Vertica client package. This package includes the ODBC/ client driver that Attunity Replicate uses to connect to Vertica.

Download Vertica Client Drivers

  1. Go to the Vertica Client Drivers page.
  2. Download the version of the Vertica client package that is compatible with the architecture of your operating system and Vertica server version.

Note Vertica drivers are forward compatible, so you can connect to the Vertica server using earlier versions of the client.

In Vertica 9.0, ODBC is both forward and backward compatible. The ODBC driver was made backwards compatible starting in Vertica 8.1.1 to enable connection to most Vertica server versions.

For more information about client and server compatibility, see Client Driver and Server Version Compatibility in the Vertica documentation.

Install Vertica Client Drivers

Install the ODBC driver and create a DSN, as described in the Vertica documentation.
