## ⏳ 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:**
|
|
```bash
|
|
# 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:**
|
|
```bash
|
|
# 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:**
|
|
```bash
|
|
# 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;\"
|
|
'"
|
|
```

## 🔧 COMENZI UTILE
|
|
|
|
### Monitoring Zilnic (PRIMARY):
|
|
|
|
```powershell
|
|
# Check ultimul backup FULL:
|
|
Get-ChildItem "C:\Users\Oracle\recovery_area\ROA\BACKUPSET" -Recurse -File |
|
|
Sort-Object LastWriteTime -Descending | Select-Object -First 1 |
|
|
Format-List Name, @{L="Size(GB)";E={[math]::Round($_.Length/1GB,2)}}, LastWriteTime
|
|
|
|
# Check transfer logs:
|
|
Get-Content "D:\rman_backup\logs\transfer_$(Get-Date -Format 'yyyyMMdd').log" -Tail 20
|
|
|
|
# Check disk space:
|
|
Get-PSDrive C,D,E | Format-Table Name, @{L="Free(GB)";E={[math]::Round($_.Free/1GB,1)}}
|
|
|
|
# Check task-uri:
|
|
Get-ScheduledTask -TaskName "Oracle*" | Format-Table TaskName, State, @{L="NextRun";E={(Get-ScheduledTaskInfo $_).NextRunTime}}
|
|
```
|
|
|
|
### Monitoring DR:
|
|
|
|
```bash
|
|
# Check backup-uri pe DR:
|
|
ssh root@10.0.20.37 "ls -lth /opt/oracle/backups/primary/ | head -10"
|
|
|
|
# Check spațiu disk:
|
|
ssh root@10.0.20.37 "df -h /opt/oracle"
|
|
|
|
# Quick verify:
|
|
ssh root@10.0.20.37 "/opt/oracle/scripts/dr/06_quick_verify_backups.sh"
|
|
```
|
|
|
|
### Disaster Recovery Activation:
|
|
|
|
```bash
|
|
# 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:
|
|
ssh root@10.0.20.37 "docker exec -u oracle oracle-standby bash -c '
|
|
export ORACLE_SID=ROA
|

## ⚠️ 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
