# Plan Complet Migrare Oracle 10g → Oracle XE 21c
## 1. Prezentare Generală
### Context Migrare
- **Sursă**: Oracle 10g Standard Edition pe Windows 7
- IP: 10.0.20.122
- Port: 1521
- Service: ROA
- Versiune: Oracle 10g
- OS: Windows 7
- **Destinație**: Oracle XE 21c în Docker LXC pe Proxmox
- IP: 10.0.20.105
- Port: 1521
- PDB: ROA (sau ROA2)
- Versiune: Oracle 21c Express Edition
- Container: Docker în LXC (ID: 108)
### Scheme de Migrat
1. **CONTAFIN_ORACLE** - Schema principală contabilitate
2. **MARIUSM_AUTO** - Schema secundară
3. **Obiecte custom din SYS** - Tabele, view-uri, proceduri, packages create manual în SYS
### Cerințe Speciale
- **Grant-uri către CONTAFIN_ORACLE** - Toate privilegiile acordate acestei scheme
- **Grant-uri către PUBLIC** - Privilegii publice pentru obiectele din scheme
- **Sinonime publice** - Toate sinonimele publice pentru acces simplificat
- **Dependințe cross-schema** - Legături între scheme și obiecte SYS
## 2. Provocări Tehnice
### Diferența de Versiuni
- **Salt major**: 11 versiuni Oracle (10g → 21c)
- **Deprecated features**: Multiple funcționalități eliminate sau modificate
- **Sintaxă SQL**: Unele comenzi necesită adaptare
- **Character set**: Posibile probleme de encoding
- **Arhitectură**: Trecere de la non-CDB la CDB/PDB
### Compatibilitate Export/Import
- **Data Pump**: Nu funcționează între 10g și 21c direct
- **Export tradițional (exp/imp)**: Metodă recomandată pentru compatibilitate
- **DDL manual**: Extragere folosind DBMS_METADATA pentru control complet
## 3. Strategia de Migrare - 3 Faze
### Faza 1: Analiză și Extragere Metadata
#### Script: `oracle-analyze-source.sh`

## 4. Validare Post-Migrare
### Script: `oracle-validate-migration.sh`
```bash
#!/bin/bash
# Validare completă post-migrare
# Test conexiuni
echo "Test conexiune CONTAFIN_ORACLE..."
sqlplus -s contafin_oracle/contafin_pass@10.0.20.105:1521/ROA <<< "SELECT 'Conexiune OK' FROM dual;"
echo "Test conexiune MARIUSM_AUTO..."
sqlplus -s mariusm_auto/mariusm_pass@10.0.20.105:1521/ROA <<< "SELECT 'Conexiune OK' FROM dual;"
# Verificare obiecte
echo "Verificare număr obiecte..."
sqlplus -s sys/OraclePass123@10.0.20.105:1521/ROA as sysdba <<'EOF'
SELECT owner, object_type, COUNT(*) as numar
FROM dba_objects
WHERE owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO')
GROUP BY owner, object_type
ORDER BY owner, object_type;
EOF
# Verificare grant-uri către PUBLIC
echo "Verificare grant-uri PUBLIC..."
sqlplus -s sys/OraclePass123@10.0.20.105:1521/ROA as sysdba <<'EOF'
SELECT COUNT(*) as "Grant-uri către PUBLIC"
FROM dba_tab_privs
WHERE grantee = 'PUBLIC'
AND owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO');
EOF
# Verificare sinonime publice
echo "Verificare sinonime publice..."
sqlplus -s sys/OraclePass123@10.0.20.105:1521/ROA as sysdba <<'EOF'
SELECT COUNT(*) as "Sinonime Publice"
FROM dba_synonyms
WHERE owner = 'PUBLIC'
AND table_owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO');
EOF
```
## 5. Rollback Plan
În caz de probleme, procedura de rollback:
```bash
#!/bin/bash
# Rollback - Revenire la starea inițială
# 1. Drop scheme din destinație
sqlplus sys/OraclePass123@10.0.20.105:1521/ROA as sysdba <<EOF
DROP USER CONTAFIN_ORACLE CASCADE;
DROP USER MARIUSM_AUTO CASCADE;
-- Drop sinonime publice
BEGIN
FOR syn IN (SELECT synonym_name
FROM dba_synonyms
WHERE owner = 'PUBLIC'
AND table_owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO')) LOOP
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM ' || syn.synonym_name;
END LOOP;
END;
/
-- Drop tablespace-uri
DROP TABLESPACE CONTAFIN_DATA INCLUDING CONTENTS AND DATAFILES;
DROP TABLESPACE CONTAFIN_INDEX INCLUDING CONTENTS AND DATAFILES;
EOF
echo "Rollback complet. Sistem revenit la starea inițială."
```
## 6. Note Importante
### Considerente de Securitate
- **Parole**: Toate parolele din scripturi trebuie schimbate
- **Backup**: Faceți backup înainte de migrare
- **Testare**: Testați întâi pe un mediu de dezvoltare
- **Validare**: Validați fiecare etapă înainte de a continua
### Probleme Cunoscute Oracle 10g → 21c
1. **LONG columns**: Convertiți la CLOB înainte de export
2. **XMLTYPE**: Poate necesita conversie la JSON
3. **CONNECT BY**: Sintaxă poate necesita ajustare
4. **WM_CONCAT**: Înlocuiți cu LISTAGG
5. **ROWIDs**: Nu păstrați ROWID în tabele
### Estimare Timp
- Analiză: 30 minute
- Export: 1-2 ore (depinde de dimensiune)
- Transfer: 30 minute
- Import: 2-3 ore
- Validare: 1 oră
- **Total**: ~6 ore pentru o bază medie
## 7. Checklist Final
- [ ] Backup bază sursă
- [ ] Verificare spațiu disk destinație
- [ ] Test conectivitate între servere
- [ ] Instalare Oracle Client tools
- [ ] Creare directoare pentru export/import
- [ ] Verificare privilegii SYS pe ambele baze
- [ ] Documentare parole și conexiuni
- [ ] Plan de rollback pregătit
- [ ] Fereastră de mentenanță programată
- [ ] Echipa de suport disponibilă
## 8. Contacte și Resurse
- **Documentație Oracle 10g to 21c**: Oracle Support Note 2079563.1
- **Oracle XE 21c în Docker**: https://container-registry.oracle.com
- **Proxmox LXC**: Container ID 108, IP 10.0.20.105
- **Windows 7 Oracle 10g**: IP 10.0.20.122
