STATUS IMPLEMENTARE - Oracle DR Backup System

Data: 2025-10-08 02:44 AM Status: 95% COMPLET - Test DR restore în progres

---

✅ CE AM FINALIZAT (95%)

FAZA 1: Setup SSH Keys ✅ COMPLET

• SSH key pair generat pe PRIMARY (10.0.20.36)
• Public key copiat pe DR (10.0.20.37)
• Test conexiune passwordless SUCCESS
• SSH keys copiate pentru SYSTEM account
• Path keys: C:\Users\Administrator\.ssh\id_rsa
• Path keys SYSTEM: C:\Windows\System32\config\systemprofile\.ssh\id_rsa

FAZA 2: Upgrade RMAN Backup Script ✅ COMPLET

• Script vechi backed up: D:\rman_backup\rman_backup.txt.backup_*
• Script nou instalat: D:\rman_backup\rman_backup.txt
• Configurare: REDUNDANCY 2, COMPRESSION BASIC
• Features: COMPRESSED BACKUPSET, ARCHIVELOG DELETE INPUT
• Test manual SUCCESS - 4min 45sec pentru 23GB → 5GB compressed
• Compression ratio: ~80% economie spațiu

FAZA 3: Instalare Transfer Script ✅ COMPLET

• Director logs creat: D:\rman_backup\logs
• Script instalat: D:\rman_backup\transfer_to_dr.ps1
• Optimizări: ssh -n, Compression=no, Cipher=aes128-gcm@openssh.com
• Feature: Skip duplicates (verifică dacă fișier există pe DR)
• Transfer speed: 950 Mbps (aproape 1 Gbps - OPTIMAL!)
• Cleanup: Păstrează ultimele 2 zile pe DR
• Test manual SUCCESS - 8/8 fișiere transferate

FAZA 4: Setup Task Scheduler ✅ COMPLET

Task 1: Oracle_DR_Transfer (03:00 AM)

• Created: Windows Task Scheduler
• Schedule: Daily at 03:00 AM (după RMAN backup de la 02:00)
• Script: D:\rman_backup\transfer_to_dr.ps1
• User: SYSTEM account
• Next run: 08-OCT-2025 03:00:00
• Status: Ready

FAZA 5: Setup Backup Incremental ✅ COMPLET

Script RMAN Incremental

• Script creat: D:\rman_backup\rman_backup_incremental.txt
• Tip: Incremental Level 1 CUMULATIVE
• Tag: MIDDAY_INCREMENTAL
• Batch launcher: D:\rman_backup\rman_backup_incremental.bat
• Test manual SUCCESS - 40 secunde

Script Transfer Incremental

• Script instalat: D:\rman_backup\transfer_incremental.ps1
• Features: Skip duplicates, optimizat ca FULL
• Test manual SUCCESS - toate fișiere skipped (deja pe DR)

Task 2: Oracle_RMAN_Incremental (14:00)

• Created: Windows Task Scheduler
• Schedule: Daily at 02:00 PM (midday)
• Script: D:\rman_backup\rman_backup_incremental.bat
• User: Administrator
• Next run: 08-OCT-2025 14:00:00
• Status: Ready

Task 3: Oracle_DR_Transfer_Incremental (14:15)

• Created: Windows Task Scheduler
• Schedule: Daily at 02:15 PM (15 min după backup incremental)
• Script: D:\rman_backup\transfer_incremental.ps1
• User: SYSTEM account
• Next run: 08-OCT-2025 14:15:00
• Status: Ready

⏳ CE RULEAZĂ ACUM (5% rămas)

FAZA 6: Test DR Restore 🔄 ÎN PROGRES

Background Process

• Proces ID: e53420
• Command: ssh root@10.0.20.37 "/opt/oracle/scripts/dr/full_dr_restore.sh"
• Status: RUNNING (pornit la 02:41:56)
• Log file: /opt/oracle/logs/dr/restore_20251008_024156.log
• Durată estimată: 10-15 minute total

Ce face scriptul:

1. ✅ Check prerequisites (15 backup files găsite)
2. ✅ WARNING: PRIMARY 10.0.20.36 răspunde (test continuat după 10 sec)
3. ✅ Cleanup old database files (în progres la ultimul check)
4. ⏳ RMAN RESTORE (în progres)
   • Restore SPFILE from backup
   • Restore CONTROLFILE
   • Restore DATABASE (FULL + incremental automat)
5. ⏳ RMAN RECOVER (urmează)
6. ⏳ Open database cu RESETLOGS (urmează)
7. ⏳ Verificare database (urmează)

---

🎯 CE MAI TREBUIE FĂCUT

Imediat (după finalizare restore):

1. Verificare status restore:

   # Check dacă procesul s-a terminat:
   ssh root@10.0.20.37 "tail -50 /opt/oracle/logs/dr/restore_20251008_024156.log"
   
   # Verificare database status:
   ssh root@10.0.20.37 "docker exec -u oracle oracle-standby bash -c '
   export ORACLE_SID=ROA
   export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
   \$ORACLE_HOME/bin/sqlplus / as sysdba <<< \"SELECT name, open_mode FROM v\\\$database;\"
   '"
   

2. Dacă restore SUCCESS:

   # Verificare obiecte database:
   ssh root@10.0.20.37 "docker exec -u oracle oracle-standby bash -c '
   export ORACLE_SID=ROA
   export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
   \$ORACLE_HOME/bin/sqlplus / as sysdba <<EOF
   SELECT COUNT(*) as total_objects FROM dba_objects;
   SELECT COUNT(*) as invalid_objects FROM dba_objects WHERE status=\"INVALID\";
   SELECT tablespace_name, status FROM dba_tablespaces;
   EXIT;
   EOF
   '"
   

3. IMPORTANT - Shutdown database pe DR după test:

   # OPREȘTE database pe DR (să nu ruleze 2 database-uri simultan!):
   ssh root@10.0.20.37 "docker exec -u oracle oracle-standby bash -c '
   export ORACLE_SID=ROA
   export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
   \$ORACLE_HOME/bin/sqlplus / as sysdba <<< \"SHUTDOWN IMMEDIATE;\"
   '"

# DOAR dacă PRIMARY e CU ADEVĂRAT down!
ssh root@10.0.20.37 "/opt/oracle/scripts/dr/full_dr_restore.sh"

# Monitorizare progres:
ssh root@10.0.20.37 "tail -f /opt/oracle/logs/dr/restore_*.log"

# După restore, verifică database:

⚠️ ISSUES & WARNINGS

Issues Rezolvate:

1. ✅ RMAN syntax errors - Fixed (removed PARALLELISM, fixed ALLOCATE CHANNEL)
2. ✅ SSH blocking în PowerShell - Fixed (added -n flag)
3. ✅ Transfer speed slow (135 Mbps) - Fixed (disabled compression, changed cipher) → 950 Mbps
4. ✅ Duplicate file transfers - Fixed (added skip duplicates check)
5. ✅ Cleanup prea agresiv - Fixed (changed de la "keep N backups" la "keep 2 days")
6. ✅ RMAN catalog mismatched objects - Fixed (CROSSCHECK + DELETE EXPIRED)

Warnings Active:

1. ⚠️ DR database test restore în progres - monitor până la finalizare
2. ⚠️ Container oracle-standby status: unhealthy - NORMAL (DB e oprit când nu e folosit)
3. ⚠️ Chown permission warning - Minor, nu afectează funcționalitatea

🎯 NEXT SESSION TASKS

1. URGENT - Verificare restore test finalizat:

   • Check log: /opt/oracle/logs/dr/restore_20251008_024156.log
   • Verifică database open mode
   • SHUTDOWN database pe DR după validare!

2. Monitoring Zi 1 (09-OCT dimineață):

   • Verifică că backup FULL de la 02:00 AM a rulat OK
   • Verifică că transfer DR de la 03:00 AM a rulat OK
   • Check logs pentru erori

3. Monitoring Zi 1 (09-OCT după-amiază):

   • Verifică că backup incremental de la 14:00 a rulat OK
   • Verifică că transfer incremental de la 14:15 a rulat OK

4. Săptămâna 1:

   • Monitorizare zilnică logs (5 min/zi)
   • Verificare spațiu disk (PRIMARY și DR)
   • Review și ajustări dacă e necesar

5. Luna 1 - Test Restore Complet:

   • Prima Duminică: test restore complet pe DR
   • Documentare RTO/RPO actual
   • Update proceduri dacă e necesar
