Course Code:	UN 107
Course Abstract:	Performance management requires a background in overall system architecture. This course takes the approach of tackling each major system of the chosen Unix platform individually, pointing out how resources are allocated, consumed, released, and reused.
Audience:	This course is designed for individuals who are performance management specialists who are or will be responsible for the tuning and capacity monitoring of one or more machines running Unix. The topics listed below are concepts that are translated into the appropriate subsystem for the client's choice of platform.
Duration:	3 days
Learning Outcomes:	Upon completion of this course, the participant will be able to: > Know the operating system subsystems and their interactions > Recognize the basic performance trade-offs of resource allocation > Describe how requests for CPU time, disk space, and memory are handled > Know the performance implications of the tunable parameters > Use performance diagnostic tools to monitor and plan for future upgrades
Course Topics:	These are the major topics discussed within each part of the course. Some flexibility is assumed since not all Unix systems are identical in all respects. Overview Areas of Performance Management Performance Management Goals System Architecture Tools for Performance Evaluation Performance Tuning Methodology Unix Kernel Environment Terminology User mode vs. Kernel mode Dynamic Driver Extensions In-kernel Threading Virtual Memory Subsystem Terminology Application Memory Access Effective to Virtual Address Translation Swapping vs. Paging Page Stealer Virtual Memory Control Tools for Monitoring Tools for Tuning System Call Subsystem What are System Calls? Platform-specific Implementation (AIX, HP-UX, Solaris, Linux) SMP and UP System Differences How They Affect Performance CPU Usage Terminology Process Scheduling Strategies The Technique in Detail (platform-specific) The Process Life Cycle The Thread Life Cycle Tools for Monitoring Tools for Tuning The Benefits of Various Coding Techniques File Systems Terminology Traditional Filesystems Comparison of Traditional vs. Vendor-specific Vendor-specific FS in Detail (JFS, VxFS, hpfs) Tools for Monitoring Tools for Tuning What You DO NOT Want to Do Disk Storage Facilities Storage Options (some are vendor-specific) Logical Volume Manager Veritas File System RAID - A Hardware Approach Policies Attributes that Affect Performance Optimizing Access Availability vs. Performance Tools for Managing Inter-process Communication Types of Process Communication Performance Aspects Network Performance (introductory topic) Concepts IP Architecture Ports and Sockets Send and Receive Queues Tools for Monitoring Performance Summary Overall Tuning Strategy Flowchart CPU-bound Workload Disk-bound Workload Paging space-bound Workload Local vs. Remote File I/O Workloads Where to Go for More Help
Prerequisites:	Familiarity with Unix concepts such as the command line shell, pipes, I/O redirection, process ids, paging space, and so forth, would be very beneficial. All information required for a proper understanding of the course material will be provided; however, hands-on use of those techniques listed above will enhance the learning experience.
