Solaris Performance and Tuning

Course:  SOLPT
Duration:  4 Days
Level:  II
Course Summary

This course is instructor led, with strong emphasis on hands-on practical sessions to reinforce the concepts introduced in the classroom.

The course provides students with an introduction to performance tuning principles and monitoring tools for the Solaris Operating System. This course presents the principles of performance tuning and usage of performance measurement tools, such as sar, vmstat, iostat, netstat, and nfsstat.

Central processing unit (CPU), memory and input/output (I/O) bottlenecks are described, with appropriate solution recommendations. Determining virtual file system performance is also covered, and a set of performance tuning heuristics is discussed.
