Oracle Solaris DTrace for System Administrators (D69844GC10)
The Oracle Solaris DTrace for System Administrators course provides students with the ability to use DTrace to diagnose application and system problems. It moves participants from basic topics such as DTrace features and architecture to advanced topics such as using DTrace, creating D Scripts, finding system problems and troubleshooting using Debug DTrace scripts. In addition, included in this course are top 10 useful scripts with a few case studies. This course moves participants to the next level of troubleshooting using DTrace
