RMS Journaling for OpenVMS

RMS Journaling for OpenVMS is a software product designed to maintain the data integrity of OpenVMS RMS files by protecting them against data loss or inconsistency due to various failure scenarios. It supports three primary methods of journaling: After-image (AI) for redoing modifications, Before-image (BI) for undoing modifications, and Recovery unit (RU) journaling for maintaining transaction atomicity via DECdtm transaction services. The software operates on a file-by-file basis and is integrated into the OpenVMS operating system. This document outlines the journaling methods, hardware and software requirements, installation considerations, recovery procedures, and licensing information.
