HP OpenVMS

This document covers the suite of system analysis tools available for OpenVMS on Alpha and I64 architectures. It is primarily intended for system programmers and analysts diagnosing kernel-mode code or device driver failures. Key topics include:

• System Dump Analyzer (SDA): Detailed instructions on invoking SDA, analyzing system dumps, and interpreting the hardware context of processors.
• SDA Extensions: Coverage of extensions like CLUE (Crash Log Utility Extractor), OCLA (On-Chip Logic Analyzer), SPL (Spinlock Tracing Utility), and XFC (Extended File Cache).
• System Code Debuggers (SCD/SDD): Explanations of how to perform system code debugging on Alpha and I64, including environment setup and connection management.
• Watchpoint Utility: How to monitor write access to specific system locations.
• System Service Logging (SSLOG): Mechanisms for recording and analyzing system service activity.
• Reference: Extensive documentation of SDA commands, their qualifiers, and callable routines for custom extensions.
