Advanced Tools for AIX Performance Analysis

• Use the trace facility to collect data and create a trace report
• Use the kernel trace facilities to analyze CPU performance issues
• Describe causes and impacts of high context switching rates
• Identify what causes a thread to block and what causes a later wake up
• Explain the relationship between the output of svmon -G, svmon -P, and svmon -S
• Calculate the amount of memory in use on the system
• Explain the relationship between svmon, vmstat, and ipcs output
• Categorize the memory in use on the system by segment type
• Identify which processes are using the most memory
• Identify which segments are using the most paging space
• Describe the characteristics of asynchronous I/O, synchronous I/O, direct I/O and concurrent I/O
• Identify if the expected type of I/O is being executed
• Tune asynchronous I/O

The audience for this advanced training include AIX technical support personnel, performance benchmark personnel, and AIX system administrators.
