Guide to OpenVMS AXP Performance Management

This document serves as a conceptual and tutorial guide for experienced system managers and users, providing comprehensive techniques for evaluating, analyzing, and optimizing performance on OpenVMS AXP systems (Version 6.1). It covers fundamental concepts of performance management, including workload management and the use of tools like ACCOUNTING and MONITOR.

The guide offers detailed strategies for investigating performance complaints and diagnosing resource limitations related to CPU, memory, and disk I/O. It explains how to tune system parameters (e.g., using AUTOGEN, Automatic Working Set Adjustment (AWSA), and swapper trimming) and implement post-installation options to enhance performance. The document outlines methods for improving system responsiveness through equitable resource sharing, reducing consumption, load balancing, and offloading. It also provides specific corrective procedures and decision-tree diagrams to aid in identifying and resolving performance bottlenecks caused by memory, I/O, or CPU constraints.
