Oracle DR: Phase 6.5 - Complete cleanup and restore scripts (TESTING)

Browse Source 
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

#### 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)

### 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
