OpenVMS System Messages and Recovery Procedures Reference Manual

This document, published in May 1993, is the second part of the OpenVMS System Messages and Recovery Procedures Reference Manual, covering system messages alphabetically from M through Z. It is intended for all OpenVMS users, including programmers and system managers.

The manual describes the standard format of OpenVMS system messages, which include a facility code, a severity level (Success, Information, Warning, Error, Fatal), a one-word identification code, and a descriptive text. It explains how the operating system reports these messages and how users can retrieve detailed information using tools like the F$MESSAGE lexical function or the HELP/MESSAGE utility from DCL prompts.

The document also provides guidance on recovery procedures for various error conditions, categorizing them into:

• Command Entry Errors: Issues with spelling, syntax, or incorrect file specifications, typically resolved by reentering the command.
• Unavailable Resources: Problems like insufficient dynamic memory or inaccessible files; some may cause processes to wait, others result in immediate errors.
• Programming Errors: Caused by incorrect arguments in procedure calls, logic errors, or improper execution environments, for which the OpenVMS debugger is recommended.
• System Software or Hardware Errors: Critical issues requiring notification of the system manager and submission of a Software Performance Report (SPR) with diagnostic information like system dump files.

This manual supersedes "VMS System Messages and Recovery Procedures Reference Manual: Part II, Version 5.4" and supports "OpenVMS AXP Version 1.5" and "OpenVMS VAX Version 6.0".
