PLP302 - Pathway Tuning
DESCRIPTION
This course is a complete coverage of tuning for the Tandem Pathway environment. You will learn how to measure performance, detect bottlenecks, and adjust parameters to improve the performance of any Pathway system.

Course Duration: 3 days (on-site)

WHO SHOULD ATTEND
Those who will be responsible for tuning and maintaining performance of Pathway applications in the Tandem environment.

PROGRAM HIGHLIGHTS

  • A comprehensive guide to tuning a Pathway-based Himalaya system - includes Measure and general performance information.
  • Detailed examination of Pathway statistics to identify bottlenecks in Pathway/iTS (TCP) and TS/MP (non-TCP) environments.
  • Step-by-step instructions for tuning a Pathway-based system, including specific recommendations for Pathway configuration attributes.
  • Course includes 14 TACL routines to simplify the analysis of Pathway configurations, format Pathway statistics, and identify general system performance problems.
  • Detailed labs to familiarize the student with Measure, Pathway statistics, and Pathway configuration.
  • Includes modules on Pathway startup/shutdown performance, programming considerations, and Pathway/XM.

PREREQUISITES

  • Pathway Administration (PLP202)
