Oracle DR: Phase 6.5 - Complete cleanup and restore scripts (TESTING)
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:** - Cleanup: ✅ TESTED (oradim works perfectly) - Backup copy: ✅ TESTED (6.7 GB in 2 min) - RMAN restore: 🟡 IN PROGRESS (expected completion 03:35-03:40) **Updated:** - DR_UPGRADE_TO_CUMULATIVE_PLAN.md: Progress tracking + solutions documented - rman_restore_final.cmd: Use F:\ mount point 🤖 Generated with Claude Code
