# Oracle DR - Windows VM Implementation Plan
|
||||
**Generated:** 2025-10-08
|
||||
**Objective:** Replace Linux LXC DR with Windows VM for same-platform RMAN restore
|
||||
**Target:** Windows VM in Proxmox, IP 10.0.20.37, Oracle 19c SE2
|
||||
|
||||
---
|
||||
|
||||
## 📋 PRE-IMPLEMENTATION CHECKLIST
|
||||
|
||||
### Current Infrastructure
|
||||
- ✅ PRIMARY: Windows Server, Oracle 19c SE2, IP: 10.0.20.36, SSH port 22122
|
||||
- ✅ Database: ROA, DBID: 1363569330
|
||||
- ✅ RMAN backups: FULL daily (02:30 AM), INCREMENTAL midday (14:00)
|
||||
- ✅ Transfer scripts: PowerShell scripts working to LXC 10.0.20.37
|
||||
- ✅ Backup size: ~7GB compressed (from 23GB), retention 2 days
|
||||
- ✅ Current DR target: Linux LXC 109 (10.0.20.37) - TO BE REPLACED
|
||||
|
||||
### What We'll Build
|
||||
- 🎯 Windows VM in Proxmox (replaces LXC 109)
|
||||
- 🎯 IP: 10.0.20.37 (same as current LXC)
|
||||
- 🎯 Oracle 19c SE2 installed (empty database template)
|
||||
- 🎯 OpenSSH Server for passwordless transfer
|
||||
- 🎯 RMAN restore scripts (automated DR recovery)
|
||||
- 🎯 Zero daily resource consumption (VM powered off when not needed)
|
||||
|
||||
### Resource Requirements
|
||||
- RAM: 4-6 GB (allocated, but VM runs only during DR events)
|
||||
- Disk: 100 GB (OS + Oracle + backup storage)
|
||||
- CPU: 2-4 vCPU
|
||||
- Network: Access to 10.0.20.0/24

|
||||
New-Item -ItemType Directory -Path "D:\oracle" -Force
|
||||
New-Item -ItemType Directory -Path "D:\oracle\backups" -Force
|
||||
New-Item -ItemType Directory -Path "D:\oracle\oradata" -Force
|
||||
New-Item -ItemType Directory -Path "D:\oracle\fra" -Force
|
||||
```
|
||||
|
||||
**✅ PHASE 1 COMPLETE:** Windows VM created, network configured, ready for Oracle installation
|
||||
|
||||

|
||||
|
||||
## 🗄️ PHASE 2: INSTALL ORACLE 19c (60-90 minutes)
|
||||
|
||||
### Step 2.1: Download Oracle 19c
|
||||
```
|
||||
On developer machine or PRIMARY:
|
||||
|
||||
1. Go to: https://www.oracle.com/database/technologies/oracle19c-windows-downloads.html
|
||||
2. Download: WINDOWS.X64_193000_db_home.zip (3.0 GB)
|
||||
3. Transfer to VM:
|
||||
- Option A: Shared folder via Proxmox
|
||||
- Option B: HTTP file server
|
||||
- Option C: Direct download in VM
|
||||
```
|
||||
|
||||
### Step 2.2: Prepare Installation (in Windows VM)
|
||||
```powershell
|
||||
# Run as Administrator
|
||||
|
||||
# Extract Oracle installation
|
||||
Expand-Archive -Path "C:\Temp\WINDOWS.X64_193000_db_home.zip" -DestinationPath "D:\oracle\product\19c\dbhome_1"
|
||||
|
||||
# Create response file for silent install
|
||||
$responseFile = @"
|
||||
oracle.install.option=INSTALL_DB_SWONLY
|
||||
UNIX_GROUP_NAME=
|
||||
INVENTORY_LOCATION=D:\oracle\oraInventory
|
||||
ORACLE_HOME=D:\oracle\product\19c\dbhome_1
|
||||
ORACLE_BASE=D:\oracle

|
||||
DECLINE_SECURITY_UPDATES=true
|
||||
"@
|
||||
|
||||
$responseFile | Out-File -FilePath "D:\oracle\db_install.rsp" -Encoding ASCII
|
||||
```
|
||||
|
||||
### Step 2.3: Silent Installation
|
||||
```powershell
|
||||
# Run as Administrator
|
||||
|
||||
cd D:\oracle\product\19c\dbhome_1
|
||||
|
||||
# Silent install (takes 30-60 minutes)
|
||||
.\setup.exe -silent -responseFile D:\oracle\db_install.rsp -ignorePrereqFailure
|
||||
|
||||
# Wait for completion, check log:
|
||||
# D:\oracle\oraInventory\logs\installActions<timestamp>.log
|
||||
|
||||
# Run root scripts (as Administrator)
|
||||
D:\oracle\product\19c\dbhome_1\root.bat
|
||||
```
|
||||
|
||||
### Step 2.4: Create Listener
|
||||
```powershell
|
||||
# Set environment
|
||||
$env:ORACLE_HOME = "D:\oracle\product\19c\dbhome_1"
|
||||
$env:PATH = "$env:ORACLE_HOME\bin;$env:PATH"
|
||||
|
||||
# Create listener.ora
|
||||
$listenerOra = @"
|
||||
LISTENER =
|
||||
(DESCRIPTION_LIST =
|
||||
(DESCRIPTION =
|
||||
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.20.37)(PORT = 1521))
|
||||
)
|
||||
)
|
||||
"@
|
||||
|
||||
$listenerOra | Out-File -FilePath "D:\oracle\product\19c\dbhome_1\network\admin\listener.ora" -Encoding ASCII
|
||||
|
||||
# Start listener
|
||||
lsnrctl start
|
||||
|
||||
# Configure listener as Windows service (optional)
|
||||
```
|
||||
|
||||
### Step 2.5: Create Empty Database Template (for faster DR restore)
|
||||
```powershell
|
||||
# Create init parameter file
|
||||
$initROA = @"
|
||||
DB_NAME=ROA
|
||||
DB_BLOCK_SIZE=8192
|
||||
COMPATIBLE=19.0.0
|
||||
MEMORY_TARGET=2G
|
||||
PROCESSES=300
|
||||
OPEN_CURSORS=300
|
||||
DB_RECOVERY_FILE_DEST=D:\oracle\fra
|
||||
DB_RECOVERY_FILE_DEST_SIZE=20G
|
||||
CONTROL_FILES=('D:\oracle\oradata\ROA\control01.ctl','D:\oracle\oradata\ROA\control02.ctl')
|
||||
"@
|
||||
|
||||
$initROA | Out-File -FilePath "D:\oracle\product\19c\dbhome_1\database\initROA.ora" -Encoding ASCII
|
||||
|
||||
# Create directory structure
|
||||
New-Item -ItemType Directory -Path "D:\oracle\oradata\ROA" -Force
|
||||
New-Item -ItemType Directory -Path "D:\oracle\fra" -Force
|
||||
|
||||
# Note: We will NOT create the database now
|
||||
# Database will be created via RMAN RESTORE during DR event
|
||||
```
|
||||
|
||||
**✅ PHASE 2 COMPLETE:** Oracle 19c installed, listener configured, ready for SSH setup
|
||||
|
||||
---
|
||||
|
||||
## 🔐 PHASE 3: CONFIGURE SSH FOR AUTOMATED TRANSFERS (20 minutes)
|
||||
|
||||
### Step 3.1: Install OpenSSH Server
|
||||
```powershell
|
||||
# Run as Administrator
|
||||
|
||||
# Install OpenSSH Server
|
||||
Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
|
||||
|
||||
# Start and enable service
|
||||
Start-Service sshd
|
||||
Set-Service -Name sshd -StartupType 'Automatic'
|
||||
|
||||
# Confirm firewall rule
|
||||
Get-NetFirewallRule -Name *ssh*
|
||||
|
||||
# Test SSH from developer machine
|
||||
# ssh Administrator@10.0.20.37
|
||||
```
|
||||
|
||||
### Step 3.2: Configure Passwordless SSH (Key-based Authentication)
|
||||
```powershell
|
||||
# On Windows VM, as Administrator
|
||||
|
||||
# Create .ssh directory
|
||||
$sshDir = "$env:ProgramData\ssh"
|
||||
New-Item -ItemType Directory -Path $sshDir -Force
|
||||
|
||||
# Get public key from PRIMARY server
|
||||
# Option A: Copy manually from PRIMARY C:\Users\Administrator\.ssh\id_rsa.pub
|
||||
# Option B: Download via SCP from developer machine
|
||||
|
||||
# For this example, manually copy the content:
|
||||
# From PRIMARY run: Get-Content C:\Users\Administrator\.ssh\id_rsa.pub
|
||||
|
||||
# On DR Windows VM:
|
||||
$publicKey = "<paste-public-key-here>"
|
||||
$publicKey | Out-File -FilePath "$sshDir\administrators_authorized_keys" -Encoding ASCII
|
||||
|
||||
# Set permissions (CRITICAL for SSH to work)
|
||||
icacls "$sshDir\administrators_authorized_keys" /inheritance:r
|
||||
icacls "$sshDir\administrators_authorized_keys" /grant "SYSTEM:(F)"
|
||||
icacls "$sshDir\administrators_authorized_keys" /grant "BUILTIN\Administrators:(F)"
|
||||
|
||||
# Restart SSH service
|
||||
Restart-Service sshd
|
||||
```
|
||||
|
||||
### Step 3.3: Configure SSH for SYSTEM Account (for scheduled tasks)
|
||||
```powershell
|
||||
# Windows scheduled tasks run as SYSTEM, so we need SYSTEM's SSH key
|
||||
|
||||
# Create SYSTEM's .ssh directory
|
||||
$systemSSHDir = "C:\Windows\System32\config\systemprofile\.ssh"
|
||||
New-Item -ItemType Directory -Path $systemSSHDir -Force
|
||||
|
||||
# Copy the same authorized_keys
|
||||
Copy-Item "$env:ProgramData\ssh\administrators_authorized_keys" `
|
||||
-Destination "$systemSSHDir\authorized_keys" -Force
|
||||
|
||||
# Set permissions
|
||||
icacls "$systemSSHDir\authorized_keys" /inheritance:r
|
||||
icacls "$systemSSHDir\authorized_keys" /grant "SYSTEM:(F)"
|
||||
```
|
||||
|
||||
### Step 3.4: Test SSH Connection from PRIMARY
|
||||
```powershell
|
||||
# On PRIMARY (10.0.20.36), test SSH to DR VM
|
||||
|
||||
# Test 1: Manual connection
|
||||
ssh -i C:\Users\Administrator\.ssh\id_rsa Administrator@10.0.20.37 "echo SSH_OK"
|
||||
|
||||
# Test 2: File transfer
|
||||
echo "test content" > C:\Temp\test.txt
|
||||
scp -i C:\Users\Administrator\.ssh\id_rsa C:\Temp\test.txt Administrator@10.0.20.37:D:\oracle\backups\
|
||||
|
||||
# If successful, you should see the file on DR VM
|
||||
```
|
||||
|
||||
**✅ PHASE 3 COMPLETE:** OpenSSH configured, passwordless authentication working
|
||||
|
||||
---
|
||||
|
||||
## 📝 PHASE 4: UPDATE TRANSFER SCRIPTS (15 minutes)
|
||||
|
||||
### Step 4.1: Modify 02_transfer_to_dr.ps1 for Windows Target
|
||||
```powershell
|
||||
# File: D:\rman_backup\02_transfer_to_dr_windows.ps1
|
||||
# Changes needed:
|
||||
|
||||
# OLD (Linux target):
|
||||
# $DRPath = "/opt/oracle/backups/primary"
|
||||
|
||||
# NEW (Windows target):
|
||||
$DRHost = "10.0.20.37"
|
||||
$DRUser = "Administrator" # Changed from "root"
|
||||
$DRPath = "D:/oracle/backups/primary" # Windows path with forward slashes for SCP
|
||||
$SSHKeyPath = "C:\Users\Administrator\.ssh\id_rsa"
|
||||
|
||||
# Update SSH commands to use Windows paths
|
||||
# Example: Directory creation
|
||||
$null = & ssh -n -i $SSHKeyPath "${DRUser}@${DRHost}" `
|
||||
"New-Item -ItemType Directory -Path '$DRPath' -Force" 2>&1
|
||||
|
||||
# Update cleanup command for Windows
|
||||
function Cleanup-OldBackupsOnDR {
|
||||
Write-Log "Cleaning up old backups on DR (keeping last 2 days)..."
|
||||
|
||||
try {
|
||||
$cleanupCmd = @"
|
||||
Get-ChildItem -Path '$DRPath' -Filter '*.BKP' |
|
||||
Where-Object { `$_.LastWriteTime -lt (Get-Date).AddDays(-2) } |
|
||||
Remove-Item -Force
|
||||
"@
|
||||
$result = & ssh -n -i $SSHKeyPath "${DRUser}@${DRHost}" "powershell -Command `"$cleanupCmd`"" 2>&1
|
||||
|
||||
Write-Log "Cleanup completed on DR"
|
||||
} catch {
|
||||
Write-Log "Cleanup warning: $_" "WARNING"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4.2: Create Updated Transfer Scripts
|
||||
```powershell
|
||||
# Save updated versions:
|
||||
# - 02_transfer_to_dr_windows.ps1 (FULL backup transfer)
|
||||
# - 02b_transfer_incremental_to_dr_windows.ps1 (INCREMENTAL transfer)
|
||||
|
||||
# Key changes for Windows:
|
||||
# 1. DRUser = "Administrator" instead of "root"
|
||||
# 2. DRPath = "D:/oracle/backups/primary" (Windows path)
|
||||
# 3. SSH commands use PowerShell instead of Linux commands
|
||||
# 4. Directory check: Test-Path instead of "test -f"
|
||||
# 5. Cleanup: Get-ChildItem instead of find
|
||||
```
|
||||
|
||||
### Step 4.3: Test Transfer Script
|
||||
```powershell
|
||||
# On PRIMARY, test the new script
|
||||
|
||||
# Manual test
|
||||
D:\rman_backup\02_transfer_to_dr_windows.ps1
|
||||
|
||||
# Check log output
|
||||
Get-Content "D:\rman_backup\logs\transfer_$(Get-Date -Format 'yyyyMMdd').log" -Tail 50
|
||||
|
||||
# Verify on DR VM
|
||||
ssh Administrator@10.0.20.37 "Get-ChildItem D:\oracle\backups\primary"
|
||||
```
|
||||
|
||||
**✅ PHASE 4 COMPLETE:** Transfer scripts updated and tested for Windows target
|
||||

# File: D:\oracle\scripts\test_restore_latest.ps1
|
||||
# Quick test to verify restore works
|
||||
|
||||
$BackupPath = "D:\oracle\backups\primary"
|
||||
$LatestBackup = Get-ChildItem "$BackupPath\*.BKP" |
|
||||
Sort-Object LastWriteTime -Descending |
|
||||
Select-Object -First 1
|
||||
|
||||
Write-Host "Latest backup: $($LatestBackup.Name)"
|
||||
Write-Host "Size: $([math]::Round($LatestBackup.Length / 1GB, 2)) GB"
|
||||
Write-Host "Date: $($LatestBackup.LastWriteTime)"
|
||||
Write-Host ""
|
||||
Write-Host "Ready to test restore? Run:"
|
||||
Write-Host "D:\oracle\scripts\rman_restore_from_primary.ps1"
|
||||
```
|
||||
|
||||
**✅ PHASE 5 COMPLETE:** RMAN restore script created and ready to test
|
||||
|
||||
---
|
||||
|
||||
## 🧪 PHASE 6: TEST DR RESTORE (30 minutes)
|
||||
|
||||
### Step 6.1: Verify Backups Transferred
|
||||
```powershell
|
||||
# On DR Windows VM
|
||||
|
||||
# Check backup files
|
||||
Get-ChildItem D:\oracle\backups\primary\*.BKP |
|
||||
Sort-Object LastWriteTime -Descending |
|
||||
Select-Object Name, @{N='SizeMB';E={[math]::Round($_.Length/1MB,2)}}, LastWriteTime
|
||||
|
||||
# Expected output: 15-20 files (FULL + INCREMENTAL + CONTROLFILE + SPFILE + ARCHIVELOGS)
|
||||
```
|
||||
|
||||
### Step 6.2: Run Test Restore
|
||||
```powershell
|
||||
# IMPORTANT: This will create a live database on DR VM
|
||||
# Make sure PRIMARY is still running (don't confuse them!)
|
||||
|
||||
# Run restore
|
||||
D:\oracle\scripts\rman_restore_from_primary.ps1
|
||||
|
||||
# Monitor progress in log
|
||||
Get-Content "D:\oracle\logs\restore_*.log" -Wait
|
||||
|
||||
# Expected duration: 10-15 minutes
|
||||
```
|
||||
|
||||
### Step 6.3: Verify Database
|
||||
```powershell
|
||||
# Connect to restored database
|
||||
sqlplus sys/romfastsoft@10.0.20.37:1521/ROA as sysdba
|
||||
|
||||
SQL> SELECT name, open_mode FROM v$database;
|
||||
# Expected: ROA, READ WRITE
|
||||
|
||||
SQL> SELECT tablespace_name, status FROM dba_tablespaces;
|
||||
# Expected: SYSTEM, SYSAUX, UNDOTBS, TS_ROA, USERS - all ONLINE
|
||||
|
||||
SQL> SELECT COUNT(*) FROM dba_tables WHERE owner='<your-app-schema>';
|
||||
# Verify application tables restored
|
||||
|
||||
SQL> EXIT;
|
||||
```
|
||||
|
||||
### Step 6.4: Shutdown DR Database (conserve resources)
|
||||
```powershell
|
||||
# After successful test, shutdown database
|
||||
sqlplus / as sysdba
|
||||
|
||||
SQL> SHUTDOWN IMMEDIATE;
|
||||
SQL> EXIT;
|
||||
|
||||
# Stop listener
|
||||
lsnrctl stop
|
||||
|
||||
# Optional: Shutdown Windows VM to conserve resources
|
||||
# (VM will be started only during actual DR events)
|
||||
```
|
||||
|
||||
**✅ PHASE 6 COMPLETE:** DR restore tested and verified working
|
||||
|
||||
---
|
||||
|
||||
## ⚙️ PHASE 7: UPDATE TASK SCHEDULER ON PRIMARY (10 minutes)
|
||||
|
||||
### Step 7.1: Update Scheduled Tasks to Use New Scripts
|
||||
```powershell
|
||||
# On PRIMARY (10.0.20.36)
|
||||
|
||||
# Task 1: FULL Backup + Transfer (already exists, just update transfer script)
|
||||
# Name: "Oracle RMAN Daily Backup + DR Transfer"
|
||||
# Trigger: Daily 02:30 AM
|
||||
# Action 1: Run RMAN backup (unchanged)
|
||||
# Action 2: UPDATE to new script
|
||||
|
||||
# Update task to use new transfer script
|
||||
$action = New-ScheduledTaskAction -Execute "PowerShell.exe" `
|
||||
-Argument "-NoProfile -ExecutionPolicy Bypass -File D:\rman_backup\02_transfer_to_dr_windows.ps1"
|
||||
|
||||
Set-ScheduledTask -TaskName "Oracle RMAN Daily Backup + DR Transfer" -Action $action
|
||||
|
||||
# Task 2: INCREMENTAL Backup + Transfer
|
||||
# Similar update for incremental task
|
||||
```
|
||||
|
||||
### Step 7.2: Test Scheduled Task Manually
|
||||
```powershell
|
||||
# On PRIMARY
|
||||
|
||||
# Run FULL backup + transfer task manually
|
||||
Start-ScheduledTask -TaskName "Oracle RMAN Daily Backup + DR Transfer"
|
||||
|
||||
# Monitor task status
|
||||
Get-ScheduledTask -TaskName "Oracle RMAN Daily Backup + DR Transfer" |
|
||||
Get-ScheduledTaskInfo
|
||||
|
||||
# Check transfer log
|
||||
Get-Content "D:\rman_backup\logs\transfer_$(Get-Date -Format 'yyyyMMdd').log" -Tail 50
|
||||
|
||||
# Verify on DR
|
||||
ssh Administrator@10.0.20.37 "Get-ChildItem D:\oracle\backups\primary -Filter *.BKP | Measure-Object"
|
||||
```
|
||||
|
||||
**✅ PHASE 7 COMPLETE:** Automated backup and transfer configured
|
||||
|
||||
---
|
||||
|
||||
## 📚 PHASE 8: CREATE DR RUNBOOK (15 minutes)
|
||||
|
||||
### Step 8.1: DR Emergency Procedure
|
||||
```markdown
|
||||
# DISASTER RECOVERY PROCEDURE
|
||||
## When PRIMARY Server (10.0.20.36) Fails
|
||||
|
||||
### PRE-REQUISITES
|
||||
- Proxmox access available
|
||||
- DR Windows VM exists (ID 109)
|
||||
- Latest backups transferred (<24h old)
|
||||
|
||||
### DR ACTIVATION STEPS (RTO: 15-20 minutes)
|
||||
|
||||
1. **Start DR Windows VM (2 minutes)**
|
||||
```
|
||||
Proxmox Web UI → VM 109 (oracle-dr-windows) → Start
|
||||
Wait for Windows to boot
|
||||
Verify network: ping 10.0.20.37
|
||||
```
|
||||
|
||||
2. **Verify Backups Present (1 minute)**
|
||||
```powershell
|
||||
# RDP or Console to 10.0.20.37
|
||||
Get-ChildItem D:\oracle\backups\primary\*.BKP |
|
||||
Sort-Object LastWriteTime -Descending |
|
||||
Select-Object -First 10
|
||||
|
||||
# Verify you see today's or yesterday's backups
|
||||
```
|
||||
|
||||
3. **Run RMAN Restore (12-15 minutes)**
|
||||
```powershell
|
||||
# Run restore script
|
||||
D:\oracle\scripts\rman_restore_from_primary.ps1
|
||||
|
||||
# Monitor log in real-time
|
||||
Get-Content D:\oracle\logs\restore_*.log -Wait
|
||||
```
|
||||
|
||||
4. **Verify Database (2 minutes)**
|
||||
```powershell
|
||||
# Connect to database
|
||||
sqlplus sys/romfastsoft@localhost:1521/ROA as sysdba
|
||||
|
||||
SQL> SELECT name, open_mode FROM v$database;
|
||||
SQL> SELECT tablespace_name, status FROM dba_tablespaces;
|
||||
SQL> -- Verify critical application tables
|
||||
SQL> EXIT;
|
||||
```
|
||||
|
||||
5. **Update Network/DNS (5 minutes)**
|
||||
```
|
||||
- Update DNS: roa-db.example.com → 10.0.20.37
|
||||
- OR: Update application connection strings to 10.0.20.37
|
||||
- Test application connectivity
|
||||
```
|
||||
|
||||
6. **Monitor & Notify**
|
||||
```
|
||||
- Monitor database alert log: D:\oracle\diag\rdbms\roa\ROA\trace\alert_ROA.log
|
||||
- Notify team that DR is active
|
||||
- Document incident timeline
|
||||
```
|
||||
|
||||
### RECOVERY BACK TO PRIMARY (When repaired)

||||
1. Create fresh RMAN backup from DR (now contains latest data)
|
||||
2. Transfer backup to repaired PRIMARY
|
||||
3. Restore on PRIMARY
|
||||
4. Switch DNS/connections back to PRIMARY
|
||||
5. Shutdown DR VM
|
||||
|
||||
### TESTING SCHEDULE

## 🔧 TROUBLESHOOTING GUIDE
|
||||
|
||||
### Issue: SSH Connection Fails
|
||||
```powershell
|
||||
# Check 1: SSH service running?
|
||||
Get-Service sshd
|
||||
|
||||
# Check 2: Firewall blocking?
|
||||
Get-NetFirewallRule -Name *ssh*
|
||||
|
||||
# Check 3: Authorized keys permissions?
|
||||
icacls "C:\ProgramData\ssh\administrators_authorized_keys"
|
||||
|
||||
# Check 4: Test from PRIMARY
|
||||
ssh -v Administrator@10.0.20.37
|
||||
```
|
||||
|
||||
### Issue: RMAN Restore Fails "CONTROLFILE not found"
|
||||
```
|
||||
# This is the cross-platform issue!
|
||||
# Solution: Ensure you're using Windows→Windows (same platform)
|
||||
# Check Oracle version matches: 19c on both sides
|
||||
```
|
||||
|
||||
### Issue: Database Won't Start
|
||||
```powershell
|
||||
# Check alert log
|
||||
Get-Content D:\oracle\diag\rdbms\roa\ROA\trace\alert_ROA.log -Tail 100
|
||||
|
||||
# Check parameter file
|
||||
Get-Content D:\oracle\product\19c\dbhome_1\database\initROA.ora
|
||||
|
||||
# Verify directories exist
|
||||
Test-Path D:\oracle\oradata\ROA
|
||||
Test-Path D:\oracle\fra
|
||||
```
|
||||
|
||||
### Issue: VM Uses Too Much Disk
|
||||
```powershell
|
||||
# Check backup retention
|
||||
Get-ChildItem D:\oracle\backups\primary\*.BKP |
|
||||
Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-3) } |
|
||||
Remove-Item -Force
|
||||
|
||||
# Check FRA usage
|
||||
SELECT * FROM V$RECOVERY_FILE_DEST;
|
||||
|
||||
# Cleanup old archives
|
||||
RMAN> DELETE NOPROMPT ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-2';
