From cbad9ee779d596e9aa9c5f4c2cf2a5eaebfc3da6 Mon Sep 17 00:00:00 2001 From: Marius Date: Fri, 10 Oct 2025 03:29:25 +0300 Subject: [PATCH] Oracle DR: Phase 6.5 - Complete cleanup and restore scripts (TESTING) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major improvements to DR restore workflow: **New Scripts:** - cleanup_database.cmd: Complete cleanup using oradim + registry deletion - rman_restore_from_zero.cmd: Copy backups to recovery_area + restore **Key Solutions Implemented:** 1. RMAN AUTOBACKUP limitation: Must have backups in recovery_area - Solution: Copy ALL backups from F:\ (NFS) to C:\...\recovery_area - Performance: 6.7 GB copied in ~2 minutes 2. Oracle service persistence issue: Service remains after sc delete - Solution: Use oradim -delete -sid ROA (proper Oracle cleanup) - Bonus: Delete registry keys to ensure clean state **Current Status:** -
