OpenVMS Performance Management

This manual provides detailed procedures for system managers to evaluate resource utilization and troubleshoot performance issues on OpenVMS systems. It covers:

• Workload Management: Strategies for managing and distributing workloads, and the system manager's role.
• Performance Options: Post-installation tuning options including file system and library management.
• Concepts: In-depth explanations of memory management (including AWSA and swapping) and OpenVMS scheduling.
• Evaluation & Diagnosis: Procedures for using tools like MONITOR and ACCOUNTING to analyze CPU, memory, and disk I/O resources to detect bottlenecks.
• Compensation: Specific corrective actions for addressing memory-limited, I/O-limited, and CPU-limited behavior, including tuning parameters and hardware considerations.

The document includes helpful decision-tree diagrams to guide the troubleshooting process.
