The Microsoft Dynamics NAV Database Resource Kit is a toolbox that is designed to help you fine-tune and troubleshoot your Microsoft Dynamics NAV 4.0 installation.
The Performance Troubleshooting Guide and the SQL Server Resource Kit have now been merged to form one set of tools - the Database Resource Kit
The Database Resource Kit consists of a number of tools and a manual. This manual contains guidelines and instructions on how to use the tools on both server options – Microsoft Dynamics NAV SQL Server Option and Microsoft Dynamics NAV Database Server.
This manual is divided into two sections; the first deals exclusively with the SQL Server Option while the second explains how to troubleshoot Microsoft Dynamics NAV on both server platforms.
All of the tools and information contained in the Database Resource Kit have been previously available in the Microsoft Dynamics NAV SQL Server Option Resource Kit and the Performance Troubleshooting Guide for Microsoft Dynamics NAV.
The tools have been tested on SQL Server 2005 and the manual has been updated to reflect recent changes that have been implemented in Microsoft Dynamics NAV.
