About this class

The Dynamic Performance Tuning and Troubleshooting with DTrace course provides students with the ability to use DTrace to diagnose application and system problems. This course replaces SA-325-S10.

Who will the lesson benefit?

Students who can benefit from this course are experienced system administrators, service support personnel, kernel developers, and application program developers

What delegates will learn

Upon Completion Of This Course, Students Should Be Able To:

• Use DTrace to find the source of intermittent problems.
• Use DTrace to look at the cause of performance problems.
• Use DTrace to help debug applications.
• Find System problems with DTrace
• Troubleshoot DTrace script problems.

What prerequisites are required

To succeed fully in this course, students should be able to administer the Solaris 10 Operating System, have a general understandaing of the Solaris kernel, and have some programming experience such as Perl or C.
