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

#### Session 2 (2025-10-10 late night - MAJOR PROGRESS)
|
||||
- ✅ **Phase 6:** Restore scripts updated to use F:\ mount
|
||||
- `rman_restore_final.cmd` modified to read backups from F:\ROA\autobackup
|
||||
- Scripts verify F:\ mount is accessible before starting restore
|
||||
- **FIXED:** Control file restore now uses `RESTORE CONTROLFILE FROM AUTOBACKUP`
|
||||
- All RMAN catalog commands point to F:\ mount
|
||||
- ✅ **Phase 6.5:** Database cleanup strategy implemented (CRITICAL FEATURE)
|
||||
- **cleanup_database.cmd** created:
|
||||
- Deletes Oracle service completely
|
||||
- Deletes ALL database files (datafiles, control files, redo logs)
|
||||
- Deletes local FRA (backups safe on F:\)
|
||||
- Does NOT recreate service (service created during restore)
|
||||
- Leaves VM in completely clean state
|
||||
- **rman_restore_from_zero.cmd** created:
|
||||
- Step 1: Calls cleanup_database.cmd (clean state)
|
||||
- Step 2.1: Creates Oracle service from PFILE
|
||||
- Step 2.2: STARTUP NOMOUNT
|
||||
- Step 2.3: Generates RMAN restore script
|
||||
- Step 2.4: Runs RMAN restore (control file → mount → catalog → restore → recover → open)
|
||||
- Step 3: Verifies database
|
||||
- **Workflow documented:**
|
||||
- **Weekly test:** restore → test → cleanup → shutdown
|
||||
- **Real disaster:** restore → keep running (NO cleanup!)
|
||||
- Saves ~8 GB disk space after each test
|
||||
- Ensures repeatable, clean DR tests from zero
|
||||
- ✅ **Backup transfer tested:**
|
||||
- Manual backup executed on PRIMARY
|
||||
- Transfer script successfully copied 6.7 GB to Proxmox
|
||||
- Backups verified accessible on F:\ in VM 109
|
||||
- ✅ **Cleanup script tested:**
|
||||
- Successfully deletes all database files
|
||||
- Successfully removes Oracle service
|
||||
- VM confirmed in clean state (no service, no DB files)
|
||||
- 🟡 **Restore script final test IN PROGRESS:**
|
||||
- **Key challenges solved:**
|
||||
- Issue 1: RMAN AUTOBACKUP doesn't work with backups on F:\ (NFS mount)
|
||||
- Solution: Copy ALL backups from F:\ to C:\Users\oracle\recovery_area before restore
|
||||
- Issue 2: Oracle service persists in registry after `sc delete`
|
||||
- Solution: Use `oradim -delete -sid ROA` + delete registry keys manually
|
||||
- **Current test status:**
|
||||
- Cleanup: ✅ PASSED (oradim delete works perfectly)
|
||||
- Service creation: ✅ PASSED
|
||||
- NOMOUNT: ✅ PASSED
|
||||
- Backup copy F:\ → recovery_area: ✅ PASSED (6.7 GB in ~2 min)
|
||||
- RMAN restore: ⏳ RUNNING NOW (expected ~10-15 min)
|
||||
- Expected completion: 2025-10-10 03:35-03:40
|
||||
|
||||
### Pending (Next Session)

### PHASE 6.5: Database Cleanup Strategy - Restore from Zero (NEW)
|
||||
|
||||
**Objective:** Keep DR VM clean by restoring from zero each time (no old database files, no Oracle services)
|
||||
|
||||
**Why this approach?**
|
||||
- ✅ **Repeatable testing:** Each test starts from known clean state
|
||||
- ✅ **No leftovers:** No old control files, redo logs, or datafiles
|
||||
- ✅ **True DR test:** Simulates real disaster scenario (no database, only Oracle software)
|
||||
- ✅ **No manual cleanup:** Automated cleanup before and after each test
|
||||
- ✅ **Save disk space:** Delete 8+ GB of database files after each test
|
||||
|
||||
#### 6.5.1 Cleanup Steps (BEFORE restore)
|
||||
|
||||
**What to delete:**
|
||||
```cmd
|
||||
REM 1. Stop and delete Oracle service
|
||||
sc stop OracleServiceROA 2>nul
|
||||
sc delete OracleServiceROA 2>nul
|
||||
|
||||
REM 2. Delete all database files (datafiles, control files, redo logs)
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.dbf 2>nul
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.ctl 2>nul
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.log 2>nul
|
||||
|
||||
REM 3. Delete local FRA (backups are on F:\ now, safe to delete)
|
||||
rmdir /S /Q C:\Users\oracle\recovery_area\ROA 2>nul
|
||||
mkdir C:\Users\oracle\recovery_area\ROA
|
||||
|
||||
REM 4. Delete old trace files (optional, saves space)
|
||||
del /Q C:\Users\oracle\diag\rdbms\roa\ROA\trace\*.* 2>nul
|
||||
|
||||
REM 5. Recreate Oracle service from pfile
|
||||
oradim -new -sid ROA -startmode manual -pfile C:\Users\oracle\admin\ROA\pfile\initROA.ora
|
||||
```
|
||||
|
||||
**Result:** Clean VM with:
|
||||
- ✅ Oracle software installed
|
||||
- ✅ PFILE exists: `C:\Users\oracle\admin\ROA\pfile\initROA.ora`
|
||||
- ✅ Oracle service created: `OracleServiceROA`
|
||||
- ❌ No database files (will be restored)
|
||||
- ❌ No control files (will be restored)
|
||||
- ❌ No datafiles (will be restored)
|
||||
|
||||
#### 6.5.2 Cleanup Steps (AFTER successful restore test)
|
||||
|
||||
**Purpose:** Leave VM clean for next test, conserve disk space
|
||||
|
||||
```cmd
|
||||
REM After verifying database is working:
|
||||
|
||||
REM 1. Shutdown database
|
||||
sqlplus / as sysdba <<EOF
|
||||
SHUTDOWN ABORT;
|
||||
EXIT;
|
||||
EOF
|
||||
|
||||
REM 2. Delete Oracle service
|
||||
sc stop OracleServiceROA
|
||||
sc delete OracleServiceROA
|
||||
|
||||
REM 3. Delete all database files
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.dbf
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.ctl
|
||||
del /Q C:\Users\oracle\oradata\ROA\*.log
|
||||
rmdir /S /Q C:\Users\oracle\recovery_area\ROA
|
||||
|
||||
REM 4. VM is now clean and ready for next test
|
||||
echo Database cleanup complete - VM ready for next test
|
||||
```
|
||||
|
||||
#### 6.5.3 Modified restore workflow
|
||||
|
||||
**OLD workflow (problematic):**
|
||||
```
|
||||
1. Start VM → database files exist from previous test
|
||||
2. Shutdown existing database
|
||||
3. Delete control files manually
|
||||
4. Restore → may fail if old files interfere
|
||||
5. Manually cleanup after test
|
||||
```
|
||||
|
||||
**NEW workflow (clean and repeatable):**
|
||||
```
|
||||
1. Start VM → clean state (no database, only software)
|
||||
2. Cleanup script: delete any leftover files + recreate service
|
||||
3. Restore from F:\ backups → fresh database
|
||||
4. Verify and test
|
||||
5. Cleanup script: delete database files
|
||||
6. Shutdown VM → ready for next test
|
||||
```
|
||||
|
||||
#### 6.5.4 Scripts created and their usage
|
||||
|
||||
**File 1:** `D:\oracle\scripts\cleanup_database.cmd`
|
||||
- **Purpose:** Standalone cleanup script
|
||||
- **What it does:**
|
||||
- Stops and deletes Oracle service
|
||||
- Deletes all database files (datafiles, control files, redo logs)
|
||||
- Deletes local FRA (backups are on F:\, safe to delete)
|
||||
- Recreates Oracle service from PFILE
|
||||
- **When to use:**
|
||||
- Before weekly test restore (to start from clean state)
|
||||
- After weekly test restore (to clean up and save disk space)
|
||||
- Manual cleanup when needed
|
||||
- **Never use:** In real disaster scenario (you want to keep the database!)
|
||||
|
||||
**File 2:** `D:\oracle\scripts\rman_restore_from_zero.cmd`
|
||||
- **Purpose:** Full restore workflow (cleanup BEFORE restore only)
|
||||
- **What it does:**
|
||||
- Calls cleanup_database.cmd at START
|
||||
- Verifies F:\ mount is accessible
|
||||
- Restores database from F:\ backups
|
||||
- Opens database with RESETLOGS
|
||||
- Verifies database is working
|
||||
- Does NOT cleanup after restore (database remains running)
|
||||
- **When to use:**
|
||||
- Weekly test restore (then manually run cleanup_database.cmd after testing)
|
||||
- **Real disaster scenario** (database remains running for production use)
|
||||
- **Result:** Database is OPEN and ready to use
|
||||
|
||||
**File 3:** `D:\oracle\scripts\rman_restore_final.cmd` (legacy)
|
||||
- **Purpose:** Restore without cleanup (assumes database files may exist)
|
||||
- **When to use:** Only if rman_restore_from_zero.cmd fails
|
||||
- **Recommendation:** Use rman_restore_from_zero.cmd instead
|
||||
|
||||
#### 6.5.5 Usage workflows
|
||||
|
||||
**A. Weekly Test Restore (Saturday morning):**
|
||||
```cmd
|
||||
REM 1. Start VM and verify F:\ mount
|
||||
dir F:\ROA\autobackup
|
||||
|
||||
REM 2. Run restore (includes cleanup before restore)
|
||||
D:\oracle\scripts\rman_restore_from_zero.cmd
|
||||
|
||||
REM 3. Verify database is working
|
||||
sqlplus / as sysdba
|
||||
SQL> SELECT * FROM V$DATABASE;
|
||||
|
||||
REM 4. Test application connectivity (optional)
|
||||
|
||||
REM 5. Cleanup after test to free disk space
|
||||
D:\oracle\scripts\cleanup_database.cmd
|
||||
|
||||
REM 6. Shutdown VM
|
||||
shutdown /s /t 60
|
||||
```
|
||||
|
||||
**B. Real Disaster Scenario (production restore):**
|
||||
```cmd
|
||||
REM 1. Start VM and verify F:\ mount
|
||||
dir F:\ROA\autobackup
|
||||
|
||||
REM 2. Run restore (includes cleanup before restore)
|
||||
D:\oracle\scripts\rman_restore_from_zero.cmd
|
||||
|
||||
REM 3. Database is now OPEN and ready for production use
|
||||
REM DO NOT run cleanup_database.cmd after this!
|
||||
|
||||
REM 4. Update application connection strings to point to DR VM
|
||||
REM 5. Keep VM running for production use
|
||||
```
|
||||
|
||||
**C. Manual cleanup (when VM gets full):**
|
||||
```cmd
|
||||
REM Run cleanup to free ~8 GB disk space
|
||||
D:\oracle\scripts\cleanup_database.cmd
|
||||
```
|
||||
|
||||
#### 6.5.6 Important notes
|
||||
|
||||
⚠️ **CRITICAL: cleanup_database.cmd deletes the entire database!**
|
||||
- Use it BEFORE weekly test restore (to start clean)
|
||||
- Use it AFTER weekly test restore (to free disk space)
|
||||
- **NEVER use it after a real disaster restore!** (you need the database running!)
|
||||
|
||||
✅ **For weekly tests:**
|
||||
- Run: `rman_restore_from_zero.cmd` → test → `cleanup_database.cmd` → shutdown VM
|
||||
- Result: VM is clean and ready for next test
|
||||
|
||||
✅ **For real disaster:**
|
||||
- Run: `rman_restore_from_zero.cmd` → database is ready → **DO NOT cleanup!**
|
||||
- Result: Database remains running for production use

|
||||
- ✅ **Control file restore FIXED:** Now uses `RESTORE CONTROLFILE FROM AUTOBACKUP`
|
||||
- ✅ **Documentation complete:** All workflows documented
|
||||
|
||||
**Next steps to complete:**
|
||||
**Next steps (ONLY ONE TEST remaining):**
|
||||
```bash
|
||||
# Phase 4 - Update scheduled tasks on PRIMARY (45 min)
|
||||
# 1. Setup SSH key from PRIMARY to Proxmox
|
||||
# 2. Test transfer scripts
|
||||
# 3. Create/modify scheduled tasks for 13:00 and 18:00
|
||||
# Phase 7 - Final end-to-end test (15-20 min)
|
||||
# On VM 109 (via RDP or SSH):
|
||||
D:\oracle\scripts\rman_restore_from_zero.cmd
|
||||
|
||||
# Phase 6 - Update DR restore script (30 min)
|
||||
# Modify restore script to use F:\ instead of local path
|
||||
# Expected flow:
|
||||
# 1. Cleanup (deletes DB + service)
|
||||
# 2. Creates Oracle service
|
||||
# 3. STARTUP NOMOUNT
|
||||
# 4. Restores control file from F:\
|
||||
# 5. MOUNT database
|
||||
# 6. Catalogs backups from F:\
|
||||
# 7. RESTORE DATABASE (5 GB, ~10-12 min)
|
||||
# 8. RECOVER DATABASE
|
||||
# 9. OPEN RESETLOGS
|
||||
# 10. Verify database
|
||||
|
||||
# Phase 7 - End-to-end test (30 min)
|
||||
# Full test: backup → transfer → mount → restore
|
||||
# If successful:
|
||||
# - Test cleanup: D:\oracle\scripts\cleanup_database.cmd
|
||||
# - Shutdown VM
|
||||
# - PROJECT COMPLETE! ✅
|
||||
```
