Configuring the Verification Server

Denodo ITPilot offers a component for automatic verification of wrappers that detects changes in the web sources and sends notifications by email when the wrappers stop working properly. The main concept on which this component is based is the storage of the results of successful queries of the wrappers. These stored queries are used by a set of configurable rules to detect invalid results in wrappers that are currently running, indicating a possible change in the web source.

This component is made available through the Verification Server, whose configuration process through the Web administration tool is detailed in this section.

In the web administration tool, the configuration options for Wrapper Servers are split across four sections: “Server Configuration”, “Database Configuration”, “Mail Configuration” and “Rules Configuration”.
