Performance Analysis and Tuning for HPE NonStop Systems

Module 1: Performance Analysis Introduction

• Steps in tuning a NonStop system and basic tuning principle
• Two aspects of response times
• Service Level Agreement (SLA) options
• Understanding your system(s)
• Measure subsystem and its entities

Module 2: CPU Subsystem

• Measure’s CPU entity

• Physical and logical disk loss and CISC and EPIC processes
• Measure’s processor data in a matrix
• NSMA architecture shown in Measure

Module 3: Queueing Theory

• Queueing theory notation and basic queueing theory formulas
• Slow and fast device queueing

Module 4: Disk Subsystem

• Integrity NonStop NS-series disk architecture
• NB-series systems storage CLIMs
• DISC and SERVERNET entities and Measure’s disk data in a matrix
• Disk cache-hit ratios and buffering non-audited files
• Disk settings with SCF and disk fragmentation

Module 5: Disk Files

• Key-sequenced file structure and buffered/unbuffered files

• Guardian Performance Analyzer (GPA)
• Tandem Performance Data Collector (TPDC)
• Tandem Performance Management (TPM)
• Availability Stats and Performance (ASAP)
• Automatic Process Balancer (APB)
• Disk Prospector (Diskpro) and Real-time Process Monitor (RPM)
• Tandem Capacity Model (TCM)

Module 9: Application Tuning

• Application performance—positive and negative factors

• Meascom output for PROCESSH and USERDEF entities
• Meascom output for TMF entity
• Remote Database Facility (RDF) performance issues

Onsite Delivery Equipment Requirements

• NonStop server with four processors and six disk volumes G06.28, H06.15, J06.04 or later with Measure, TPDC, and RPM installed
• Private class requests:
• Might require up to two days set-up time on a customer system prior to the class
• Access to a supergroup logon for the instructor
