## 🔧 Acces la Oracle prin LXC

> **IMPORTANT:** Nu ai nevoie de user/parolă pentru LXC 108!
> Accesul se face prin Proxmox folosind comenzile `pct`.

### Metoda 1: Intrare în LXC 108
```bash
# SSH în Proxmox
ssh root@10.0.20.201

# Intrare în LXC 108
pct enter 108

# Acum poți folosi comenzi Docker direct
docker ps
docker logs oracle-xe --tail 50
```

### Metoda 2: Execuție Directă din Proxmox
```bash
# Verificare PDB-uri
ssh root@10.0.20.201 'pct exec 108 -- docker exec oracle-xe bash -c "echo \"SELECT name, open_mode FROM v\\\$pdbs;\" | sqlplus -s sys/romfastsoft@localhost:1521/XE as sysdba"'

# Restart Oracle container
ssh root@10.0.20.201 "pct exec 108 -- docker restart oracle-xe"
```

### Metoda 3: SQL*Plus Direct în Container
```bash
# Intrare în container Oracle
pct exec 108 -- docker exec -it oracle-xe bash

# SQL*Plus din container
docker exec oracle-xe sqlplus sys/romfastsoft@localhost:1521/roa as sysdba
```

## 🔍 Verificări și Comenzi SQL Utile

### Status PDB-uri
```sql
-- Verificare status PDB-uri
SELECT name, open_mode, restricted FROM v$pdbs;

-- Deschidere PDB (dacă e MOUNTED)
ALTER PLUGGABLE DATABASE roa OPEN;
ALTER PLUGGABLE DATABASE roa2 OPEN;
ALTER PLUGGABLE DATABASE ALL SAVE STATE;
```

### Verificare Tablespace-uri
```sql
-- Tablespace-uri și utilizare în ROA2
SELECT
  tablespace_name,
  ROUND(bytes/1024/1024, 2) as MB,
  ROUND(maxbytes/1024/1024, 2) as MAX_MB,
  autoextensible
FROM dba_data_files
WHERE tablespace_name='ROA';

-- Spațiu liber
SELECT
  tablespace_name,
  ROUND(SUM(bytes)/1024/1024, 2) as FREE_MB
FROM dba_free_space
GROUP BY tablespace_name;
```

### Status Obiecte și Scheme
```sql
-- Număr obiecte per schema în ROA2
SELECT
  owner,
  COUNT(*) total_objects,
  SUM(CASE WHEN status='VALID' THEN 1 ELSE 0 END) valid_objects,
  SUM(CASE WHEN status='INVALID' THEN 1 ELSE 0 END) invalid_objects
FROM dba_objects
WHERE owner IN ('CONTAFIN_ORACLE', 'FIRMANOUA')
GROUP BY owner;

-- Tipuri obiecte
SELECT owner, object_type, COUNT(*)
FROM dba_objects
WHERE owner IN ('CONTAFIN_ORACLE', 'FIRMANOUA')
GROUP BY owner, object_type
ORDER BY owner, COUNT(*) DESC;
```

### Useri și Profiluri
```sql
-- Verificare useri și profile în PDB
SELECT username, account_status, profile, created
FROM dba_users
WHERE username IN ('CONTAFIN_ORACLE', 'FIRMANOUA', 'MARIUSM_AUTO')
ORDER BY created DESC;

-- Verificare limită parole (PASSWORD_LIFE_TIME)
SELECT profile, resource_name, limit
FROM dba_profiles
WHERE resource_name = 'PASSWORD_LIFE_TIME'
ORDER BY profile;
```

### Sinonime Publice
```sql
-- Verificare sinonime publice CONTAFIN_ORACLE
SELECT COUNT(*) as total_synonyms
FROM dba_synonyms
WHERE owner = 'PUBLIC'
AND table_owner = 'CONTAFIN_ORACLE';

-- Detalii sinonime
SELECT synonym_name, table_owner, table_name
FROM dba_synonyms
WHERE owner = 'PUBLIC'
AND table_owner = 'CONTAFIN_ORACLE'
ORDER BY synonym_name;
```

### Grant-uri către PUBLIC
```sql
-- Număr grant-uri către PUBLIC
SELECT COUNT(*) as total_grants
FROM dba_tab_privs
WHERE grantee = 'PUBLIC'
AND owner IN ('CONTAFIN_ORACLE', 'SYS');

-- Detalii grant-uri
SELECT owner, table_name, privilege, grantee
FROM dba_tab_privs

## 🚨 Troubleshooting Oracle

### Verificare Conexiune Oracle
```bash
# Test ping LXC 108
ping -c 3 10.0.20.121

# Test port Oracle listener
nc -zv 10.0.20.121 1521

# Test SQL*Plus conexiune
sqlplus sys/romfastsoft@10.0.20.121:1521/roa as sysdba
```

### Restart Oracle Database
```bash
# Opțiunea 1: Restart container Docker (RAPID)
ssh root@10.0.20.201 "pct exec 108 -- docker restart oracle-xe"

# Opțiunea 2: Restart LXC complet
ssh root@10.0.20.201 "pct restart 108"

# Verificare după restart
ssh root@10.0.20.201 "pct exec 108 -- docker ps"
```

### Verificare Status Container
```bash
# Status Docker container
ssh root@10.0.20.201 "pct exec 108 -- docker ps"

# Healthcheck Oracle
ssh root@10.0.20.201 "pct exec 108 -- docker inspect oracle-xe | grep -A 10 Health"

# Loguri Oracle
ssh root@10.0.20.201 "pct exec 108 -- docker logs oracle-xe --tail 100"
```

### PDB nu se deschide (MOUNTED)
```bash
# Deschidere manuală PDB
ssh root@10.0.20.201 'pct exec 108 -- docker exec oracle-xe bash -c "echo \"ALTER PLUGGABLE DATABASE ALL OPEN; ALTER PLUGGABLE DATABASE ALL SAVE STATE;\" | sqlplus -s sys/romfastsoft@localhost:1521/XE as sysdba"'
```

### Probleme Maximum Open Cursors
```sql
-- Verificare valoare curentă
SELECT name, value FROM v$parameter WHERE name = 'open_cursors';

-- Creștere limită cursoare (dacă apar erori ORA-01000)
ALTER SYSTEM SET OPEN_CURSORS=1000 SCOPE=BOTH SID='*';
```

### Verificare Alert Log Oracle
```bash
# Alert log location în container
ssh root@10.0.20.201 "pct exec 108 -- docker exec oracle-xe tail -100 /opt/oracle/diag/rdbms/xe/XE/trace/alert_XE.log"
```

## 📝 Notițe Importante

### Diferențe Oracle 10g vs 21c
- **Oracle 10g** folosește SID (ORCL) - sistem vechi, decommissioned
- **Oracle 21c** folosește SERVICE_NAME (roa, roa2) - sistem actual
- Migrare: Export DMP Oracle 10g → Import Data Pump Oracle 21c (impdp)

### Profile Parole
- **ROA:** Parolele pot expira (setări default Oracle)
- **ROA2:** Parolele NU expiră (PASSWORD_LIFE_TIME UNLIMITED)

### VM 201 - Windows 11 (Client Aplicații)
- **VMID:** 201
- **Nume:** roacentral
- **Host:** 10.0.20.201 (Proxmox pvemini)
- **OS:** Windows 11 (24H2)
- **Rol:** Client pentru aplicații Windows, SQL*Plus client
- **NU** rulează Oracle Database (migrat în LXC 108 Docker)

### Istoric Migrare
- **VM 107 (Windows 7 Oracle 10g)** - DECOMMISSIONED
  - Fostă sursă Oracle 10g pentru migrare DMP
  - Archive DMP: firmanoua.zip (backup arhivat)
  - Status: Stopped/Removed (înlocuit de LXC 108)
