Performance Analysis and Tuning for HPE NonStop Systems - U4195S


Become familiar with the system load balance approach and performance tuning concepts for your HPE NonStop system. Learn how to capture and analyze performance data, then adapt the adjustments to maximize performance and increase system utilization. Topics include Measure, Measure entities, queuing theory, TPM, RPM, ViewSys, Web ViewPoint practical approaches to system tuning, and using performance tools. The course is 60 percent lecture and 40 percent hands-on labs using NonStop servers.

After you successfully complete this course, expect to be able to:
  • Apply the basic tuning principle for NonStop 
  • Analyze Measure’s key entities and use Reload Analyzer
  • Apply several basic queuing theory formulas
  • Analyze disk cache-hit ratios and fragmentation
  • Calculate a volume’s true write cache-hit ratio
  • Analyze process priorities and process memory consumption
  • Identify processes with long $RECEIVE queues
  • Evaluate TCP process and server class parameters for best performance
  • Use Measure, SQLCI, and MXCI to analyze NonStop SQL/MP and NonStop  SQL/MX performance
  • Identify positive and negative factors in application performance
