- Introduction
  BigFix aims to solve the increasingly complex problem of keeping your critical systems updated, compatible, and free of security issues. It uses patented Fixlet technology to identify vulnerable computers in your enterprise. With just a few mouse-clicks you can remediate them across your entire network from a central console.
- BigFix Platform Unicode Support Overview

- SQL Server parallelism optimization
  The performance of an SQL Server database instance can often be improved by small tweaks. Performance might also be hindered by simple oversights. In fact, some SQL Server parallelism settings have suboptimal default values. Moreover, they have to be re-tuned after an hardware upgrade. Other issues might arise from inadvertent hardware configurations, especially when SQL Server is hosted on a virtual machine (VM).
