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

CONTAFIN_ORACLE - Schema principală contabilitate
MARIUSM_AUTO - Schema secundară
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`

#!/bin/bash
# Analiză completă a bazei de date sursă Oracle 10g

SET TRIMSPOOL ON

-- 1. INVENTAR OBIECTE PRINCIPALE
SPOOL object_inventory.txt

        AND referenced_type = 'SYNONYM'
     ))
ORDER BY synonym_name;
SPOOL OFF

-- 4. ANALIZA DEPENDINTE
SPOOL dependencies_analysis.txt

     OR referenced_owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO'))
ORDER BY owner, name, referenced_owner, referenced_name;
SPOOL OFF

-- 5. STATISTICI TABELE (pentru validare post-migrare)
SPOOL table_statistics.txt
SELECT owner || '.' || table_name || ':ROWS=' || num_rows
FROM dba_tables
WHERE owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO')
ORDER BY owner, table_name;

4. Validare Post-Migrare

Script: `oracle-validate-migration.sh`

#!/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;"

AND table_owner IN ('CONTAFIN_ORACLE', 'MARIUSM_AUTO');

5. Rollback Plan

În caz de probleme, procedura de rollback:

#!/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

LONG columns: Convertiți la CLOB înainte de export
XMLTYPE: Poate necesita conversie la JSON
CONNECT BY: Sintaxă poate necesita ajustare
WM_CONCAT: Înlocuiți cu LISTAGG
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
