+# 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

+
+## 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

+# Ghid Instalare Oracle XE 21 în LXC pe Proxmox
+
+## Rezumat Opțiuni
+
+Din cercetare rezultă că **nu există template-uri LXC cu Oracle XE pre-instalat**. Cele mai viabile opțiuni sunt:
+
+1. **Docker-in-LXC** (Recomandat) - Cea mai simplă și automatizată
+2. **Instalare manuală în Oracle Linux LXC** - Mai directă dar complexă
+3. **Script-uri de automatizare** - Soluții comunitate
+
+## Opțiunea 1: Docker-in-LXC (RECOMANDAT) ✅
+
+### Avantaje
+- Folosește imaginea oficială Oracle cu automatizare completă
+- Configurare minimă manuală
+- Suport oficial Oracle pentru containerizare
+- Ușor de actualizat și întreținut
+
+### Dezavantaje
+- Overhead suplimentar Docker
+- Container în container (LXC → Docker)
+
+### Pași de Instalare
+
+#### 1. Creare Container LXC Privilegiat
+
+SSH pe Proxmox:
+```bash
+ssh root@10.0.20.201
+
+# Download template Ubuntu 22.04 dacă nu există
+pveam update
+pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.gz
+
+# Creare container privilegiat
+pct create 300 local:vztmpl/ubuntu-22.04-standard_22.04-1_amd64.tar.gz \
+  --hostname oracle-xe \
+  --cores 2 \
+  --memory 4096 \
+  --swap 2048 \
+  --rootfs local-zfs:20 \
+  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
+  --unprivileged 0 \
+  --features nesting=1,keyctl=1 \
+  --ostype ubuntu
+```
+
+#### 2. Configurare Container pentru Docker
+
+```bash
+# Start container
+pct start 300
+
+# Intrare în container
+pct enter 300
+
+# Update sistem
+apt update && apt upgrade -y
+
+# Instalare Docker
+apt install -y ca-certificates curl gnupg lsb-release
+mkdir -p /etc/apt/keyrings
+curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
+apt update
+apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
+
+# Verificare Docker
+docker --version
+systemctl enable docker
+systemctl start docker
+```
+
+#### 3. Deploy Oracle XE 21 cu Docker
+
+```bash
+# Crearea directoarelor pentru persistență
+mkdir -p /opt/oracle/oradata
+mkdir -p /opt/oracle/scripts/setup
+mkdir -p /opt/oracle/scripts/startup
+
+# Pull imagine oficială Oracle XE
+docker pull container-registry.oracle.com/database/express:21.3.0-xe
+
+# Rulare container Oracle XE
+docker run -d \
+  --name oracle-xe \
+  -p 1521:1521 \
+  -p 5500:5500 \
+  -e ORACLE_PWD=OraclePass123 \
+  -e ORACLE_CHARACTERSET=AL32UTF8 \
+  -v /opt/oracle/oradata:/opt/oracle/oradata \
+  -v /opt/oracle/scripts/setup:/opt/oracle/scripts/setup \
+  -v /opt/oracle/scripts/startup:/opt/oracle/scripts/startup \
+  container-registry.oracle.com/database/express:21.3.0-xe
+
+# Verificare status
+docker ps
+docker logs -f oracle-xe
+
+# Așteptare până DB este ready (durează ~5-10 minute prima dată)
+# Căutați în logs: "DATABASE IS READY TO USE!"
+```
+
+#### 4. Configurare Acces și Testare
+
+```bash
+# Obținere IP container LXC
+ip addr show eth0
+
+# Test conexiune din container
+docker exec -it oracle-xe sqlplus sys/OraclePass123@localhost:1521/XE as sysdba
+
+# În SQL*Plus
+SQL> SELECT banner FROM v$version;
+SQL> exit
+
+# Creare user pentru aplicații
+docker exec -it oracle-xe sqlplus sys/OraclePass123@localhost:1521/XE as sysdba <<EOF
+CREATE USER appuser IDENTIFIED BY AppPass123;
+GRANT CONNECT, RESOURCE TO appuser;
+GRANT CREATE SESSION TO appuser;
+GRANT UNLIMITED TABLESPACE TO appuser;
+exit;
+EOF
+
+# Auto-start la boot
+docker update --restart=unless-stopped oracle-xe
+```
+
+#### 5. Acces din Exterior
+
+Din WSL sau alt sistem:
+```bash
+# Conexiune SQL*Plus
+sqlplus appuser/AppPass123@10.0.20.XXX:1521/XE
+
+# Conexiune cu tool-uri GUI
+# JDBC URL: jdbc:oracle:thin:@10.0.20.XXX:1521:XE
+# Enterprise Manager: http://10.0.20.XXX:5500/em
+```
+
+## Opțiunea 2: Instalare Manuală în Oracle Linux LXC
+
+### Pași de Instalare
+
+#### 1. Download și Creare Template Oracle Linux
+
+```bash
+# Pe Proxmox
+cd /var/lib/vz/template/cache/
+
+# Download Oracle Linux 8 rootfs
+wget https://images.linuxcontainers.org/images/oraclelinux/8/amd64/default/20240101_00:00/rootfs.tar.xz -O oraclelinux-8_amd64.tar.xz
+
+# Creare container
+pct create 301 local:vztmpl/oraclelinux-8_amd64.tar.xz \
+  --hostname oracle-xe-native \
+  --cores 2 \
+  --memory 4096 \
+  --swap 2048 \
+  --rootfs local-zfs:20 \
+  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
+  --unprivileged 0 \
+  --features nesting=1
+```
+
+#### 2. Pregătire Sistem pentru Oracle XE
+
+```bash
+pct start 301
+pct enter 301
+
+# Configurare hostname și hosts
+echo "oracle-xe-native" > /etc/hostname
+echo "127.0.0.1 oracle-xe-native" >> /etc/hosts
+
+# Disable IPv6 (Oracle XE compatibility)
+echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
+echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
+sysctl -p
+
+# Install pachete necesare
+yum install -y oracle-database-preinstall-21c
+yum install -y wget unzip
+
+# Configurare kernel parameters pentru Oracle
+cat >> /etc/sysctl.conf <<EOF
+fs.aio-max-nr = 1048576
+fs.file-max = 6815744
+kernel.shmall = 2097152
+kernel.shmmax = 4294967295
+kernel.shmmni = 4096
+kernel.sem = 250 32000 100 128
+net.ipv4.ip_local_port_range = 9000 65500
+net.core.rmem_default = 262144
+net.core.rmem_max = 4194304
+net.core.wmem_default = 262144
+net.core.wmem_max = 1048576
+EOF
+sysctl -p
+```
+
+#### 3. Download și Instalare Oracle XE 21c
+
+```bash
+# Download Oracle XE (necesită cont Oracle)
+# Manual: Download de pe https://www.oracle.com/database/technologies/xe-downloads.html
+# Transfer fișierul oracle-database-xe-21c-1.0-1.ol8.x86_64.rpm în container
+
+# Sau folosește wget cu link direct (dacă ai)
+cd /tmp
+# wget [ORACLE_XE_DOWNLOAD_LINK]
+
+# Instalare RPM
+yum localinstall -y oracle-database-xe-21c-1.0-1.ol8.x86_64.rpm
+
+# Configurare automată
+/etc/init.d/oracle-xe-21c configure <<EOF
+OraclePass123
+OraclePass123
+EOF
+
+# Set environment
+echo 'export ORACLE_HOME=/opt/oracle/product/21c/dbhomeXE' >> /etc/profile
+echo 'export PATH=$ORACLE_HOME/bin:$PATH' >> /etc/profile
+echo 'export ORACLE_SID=XE' >> /etc/profile
+source /etc/profile
+
+# Enable auto-start
+systemctl enable oracle-xe-21c
+systemctl start oracle-xe-21c
+```
+
+## Opțiunea 3: Script-uri de Automatizare
+
+### Folosire Repository-uri GitHub
+
+```bash
+# Exemplu cu gvenzl/oci-oracle-xe
+git clone https://github.com/gvenzl/oci-oracle-xe
+cd oci-oracle-xe
+
+# Build container image
+./buildContainerImage.sh -v 21.3.0 -x
+
+# Sau folosire directă cu Docker
+docker run -d \
+  -p 1521:1521 \
+  -e ORACLE_PASSWORD=OraclePass123 \
+  gvenzl/oracle-xe:21-slim
+```
+
+## Cerințe Hardware și Configurare
+
+### Resurse Minime Container
+- **CPU:** 2 cores
+- **RAM:** 4GB (minim 2GB)
+- **Disk:** 20GB (9GB minim pentru Oracle)
+- **Swap:** 2GB
+
+### Porturi Necesare
+- **1521:** Oracle Listener
+- **5500:** Enterprise Manager Express
+- **8080:** APEX (opțional)
+
+### Configurări LXC Specifice
+```bash
+# În /etc/pve/lxc/[CTID].conf pe Proxmox
+lxc.apparmor.profile: unconfined
+lxc.cgroup2.devices.allow: a
+lxc.cap.drop:
+lxc.mount.auto: proc:rw sys:rw
+```
+
+## Troubleshooting
+
+### Probleme Comune
+
+#### 1. Insufficient Memory
+```bash
+# Verificare memorie
+free -h
+# Ajustare din Proxmox
+pct set [CTID] --memory 6144
+```
+
+#### 2. Docker în LXC nu pornește
+```bash
+# Verificare privilegii container
+# Container trebuie să fie privilegiat (unprivileged=0)
+# Features: nesting=1, keyctl=1
+```
+
+#### 3. Oracle XE nu pornește
+```bash
+# Check logs
+docker logs oracle-xe
+# Sau pentru instalare nativă
+tail -f /opt/oracle/diag/rdbms/xe/XE/trace/alert_XE.log
+```
+
+#### 4. Conexiune refuzată
+```bash
+# Verificare listener
+docker exec oracle-xe lsnrctl status
+# Verificare firewall
+iptables -L
+```
+
+## Script Complet Automatizare Docker-in-LXC

+## Conexiune și Utilizare
+
+### String-uri de Conexiune
+```
+# SQL*Plus
+sqlplus sys/OraclePass123@localhost:1521/XE as sysdba
+
+# JDBC
+jdbc:oracle:thin:@10.0.20.XXX:1521:XE
+
+# TNS
+XE =
+  (DESCRIPTION =
+    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.20.XXX)(PORT = 1521))
+    (CONNECT_DATA =
+      (SERVER = DEDICATED)
+      (SERVICE_NAME = XE)
+    )
+  )
+```
+
+### Tool-uri Recomandate
+- **SQL Developer** - Oracle oficial
+- **DBeaver** - Universal database tool
+- **Enterprise Manager Express** - http://10.0.20.XXX:5500/em
+
+## Note Finale
+
+1. **Varianta Docker-in-LXC este cea mai simplă** și recomandată pentru majoritatea cazurilor
+2. **Backup-uri regulate** folosind Proxmox vzdump
+3. **Monitorizare resurse** - Oracle XE poate consuma multă memorie
+4. **Licențiere** - Oracle XE este gratuită dar cu limitări (12GB data, 2GB RAM, 2 CPU threads)
+5. **Securitate** - Schimbați parolele default, configurați firewall
