Loading Additional Drivers

This article describes how to add external drivers not included with the MDM packages.

Overview

Drivers for some of the third-party data sources and other components are not included in standard packages due to the size or licensing reasons. It is, however, possible for the MDM Server to load those additional drivers from a designated external drivers folder specified in the MDM Server application.properties (see MDM Server Application Properties, section External drivers folder (named lib-ext by default). The individual JARs can be stored in subfolders.

See the following sections for examples of configuration and lists of drivers required by the third-party components.
