+# Oracle Modes Configuration Guide - UNIFIED
+
+## 🎯 Un Singur Dockerfile + Docker Compose
+
+| Oracle Version | Configurație .env | Comandă Build | Port |
+|---------------|-------------------|---------------|------|
+| 10g (test)    | `INSTANTCLIENTPATH=...` | `docker-compose up --build` | 5003 |
+| 11g (prod)    | `INSTANTCLIENTPATH=...` | `docker-compose up --build` | 5003 |
+| 12.1+ (nou)   | `FORCE_THIN_MODE=true` | `ORACLE_MODE=thin docker-compose up --build` | 5003 |
+
+---
+
+## 🔧 THICK MODE (Oracle 10g/11g) - DEFAULT
+
+### Configurare .env:
+```env
+# Uncomment această linie pentru thick mode:
+INSTANTCLIENTPATH=/opt/oracle/instantclient_23_9
+
+# Comment această linie:
+# FORCE_THIN_MODE=true
+```
+
+### Rulare:
+```bash
+docker-compose up --build -d
+curl http://localhost:5003/health
+```
+
+---
+
+## 🚀 THIN MODE (Oracle 12.1+) 
+
+### Varianta 1 - Prin .env (Recomandat):
+```env
+# Comment această linie pentru thin mode:
+# INSTANTCLIENTPATH=/opt/oracle/instantclient_23_9  
+
+# Uncomment această linie:
+FORCE_THIN_MODE=true
+```
+
+### Varianta 2 - Prin build argument:
+```bash
+ORACLE_MODE=thin docker-compose up --build -d
+```
+
+### Test:
+```bash
+curl http://localhost:5003/health
+```
+
+---
+
+## 🔄 LOGICA AUTO-DETECT
+
+Container-ul detectează automat modul:
+
+1. **FORCE_THIN_MODE=true** → **Thin Mode**
+2. **INSTANTCLIENTPATH** există → **Thick Mode**
+3. Build cu **ORACLE_MODE=thin** → **Thin Mode**  
+4. Default → **Thick Mode**
+
+---
+
+## 🛠️ COMENZI SIMPLE
+
+### Pentru Oracle 10g/11g (setup-ul tău actual):
+```bash
+# Verifică .env să aibă:
+grep INSTANTCLIENTPATH ./api/.env
+
+# Start
+docker-compose up --build -d
+curl http://localhost:5003/test-db
+```
+
+### Pentru Oracle 12.1+ (viitor):
+```bash
+# Editează .env: decomentează FORCE_THIN_MODE=true
+# SAU rulează direct:
+ORACLE_MODE=thin docker-compose up --build -d
+curl http://localhost:5003/test-db
+```
+
+### Switch rapid:
+```bash
+# Stop
+docker-compose down
+
+# Edit .env (change INSTANTCLIENTPATH ↔ FORCE_THIN_MODE)
+# Start
+docker-compose up --build -d
+```
+
+---
+
+## ⚠️ TROUBLESHOOTING
+
+### Eroare DPY-3010 în Thin Mode:
+```
+DPY-3010: connections to this database server version are not supported
+```
+**Soluție:** Oracle este 11g sau mai vechi → folosește thick mode
+
+### Eroare libaio în Thick Mode:
+```
+Cannot locate a 64-bit Oracle Client library: libaio.so.1
+```
+**Soluție:** Rebuild container (fix automat în Dockerfile.thick)
+
+### Container nu pornește:
+```bash
+docker-compose logs
+docker-compose down && docker-compose up --build
+```
+
+---
+
+## 📊 COMPARAȚIE PERFORMANȚĂ
+
+| Aspect | Thick Mode | Thin Mode |
+|--------|------------|-----------|
+| Container Size | ~200MB | ~50MB |
+| Startup Time | 10-15s | 3-5s |
+| Memory Usage | ~100MB | ~30MB |
+| Oracle Support | 10g+ | 12.1+ |
+| Dependencies | Instant Client | None |
+
+---
+
+## 🔧 DEZVOLTARE
+
+### Pentru dezvoltatori:
+1. **Thick mode** pentru compatibilitate maximă
+2. **Thin mode** pentru development rapid pe Oracle nou
+3. **Auto-detect** în producție pentru flexibilitate
+
+### Testare ambele moduri:
+```bash
+# Thick pe port 5003
+docker-compose -f docker-compose.thick.yaml up -d
+
+# Thin pe port 5004  
+docker-compose -f docker-compose.thin.yaml up -d
+
+# Test ambele
+curl http://localhost:5003/health
+curl http://localhost:5004/health
+```
