# ROA Oracle Database Setup for Windows

## Overview

Scripts and documentation for setting up ROA Oracle Database on Windows servers:

| Scenario | Description |
|----------|-------------|
| **New Server** | Oracle 21c SE (non-CDB) or XE (CDB/PDB) + CONTAFIN_ORACLE.dmp |
| **Migration** | Import existing DMP files (CONTAFIN_ORACLE + 30-50 companies) |
| **Add Company** | Add new company schema to existing server |

---

## Prerequisites

- Windows Server 2016+ or Windows 10/11
- Oracle 21c Standard Edition or Express Edition installed
- Administrator privileges
- PowerShell 5.1+
- Minimum 8GB RAM (16GB recommended for SE)
- 50GB free disk space

---

## Quick Start

1. Download Oracle 21c XE or SE from Oracle
2. Install Oracle (see `docs/00-INSTALL-ORACLE-XE.md` or `docs/00-INSTALL-ORACLE-SE.md`)
3. Copy DMP files to `C:\DMPDIR\`
4. Copy `config.example.ps1` to `config.ps1` and edit values
5. Run scripts in order: `01` -> `07`

```powershell
# Example workflow
.\01-setup-database.ps1
.\02-create-sys-objects.ps1
.\03-import-contafin.ps1
.\04-create-synonyms-grants.ps1
.\05-import-companies.ps1
.\07-verify-installation.ps1
```

---

## Configuration

Copy `config.example.ps1` to `config.ps1` and edit:

| Parameter | XE Value | SE Value |
|-----------|----------|----------|
| `ORACLE_HOME` | `C:\app\oracle\product\21c\dbhomeXE` | `C:\app\oracle\product\21c\dbhome_1` |
| `SERVICE_NAME` | `XEPDB1` | `ROA` |
| `DATAFILE_DIR` | `C:\app\oracle\oradata\XE\XEPDB1` | `C:\app\oracle\oradata\ROA` |

## Architecture Differences

### Oracle 21c Standard Edition (non-CDB)

Traditional single-database architecture (legacy compatibility).

| Feature | Value |
|---------|-------|
| Architecture | Single database (non-CDB) |
| Database Name | ROA |
| Service Name | ROA |
| SID | ROA |
| Connection | `system/pass@ROA` |
| Datafiles | `C:\app\oracle\oradata\ROA\` |

**Advantages:**
- Simpler administration
- Compatible with Oracle 10g migration scripts
- No PDB management overhead

### Oracle 21c Express Edition (CDB/PDB)

Modern multitenant architecture with Container Database.

| Feature | Value |
|---------|-------|
| Architecture | Container + Pluggable Database |
| CDB Name | XE |
| PDB Name | XEPDB1 |
| Service Name | XEPDB1 (for applications) |
| Connection | `system/pass@XEPDB1` |
| Datafiles | `C:\app\oracle\oradata\XE\XEPDB1\` |

**Advantages:**
- Free license (Express Edition)
- Modern architecture
- Easy backup/clone of PDB

**Connection Warning:**
> Always connect to **XEPDB1** (PDB), not to **XE** (CDB root) for ROA operations!

---

## Standard Passwords

| User | Password | Notes |
|------|----------|-------|
| SYS | romfastsoft | SYSDBA |
| SYSTEM | romfastsoft | DBA |
| CONTAFIN_ORACLE | ROMFASTSOFT | Common schema |
| Company schemas | From NOM_FIRME.parola | See company-specific config |

> **Security Note:** Change passwords in production environments!

---

## DMP Files Required

### For New Installation

| File | Description | Size |
|------|-------------|------|
| `contafin_oracle.dmp` | Common schema (rights, updates, etc.) | ~50MB |
| `[company].dmp` | Company schema (one per company) | ~100-500MB each |

### Obtaining DMP Files

Export from existing Oracle 18c server (for compatibility):

```bash
# From LXC 108 (Oracle 18c - port 1522)
docker exec oracle18-xe expdp system/romfastsoft@localhost:1521/XEPDB1 \
  SCHEMAS=CONTAFIN_ORACLE DIRECTORY=DMPDIR DUMPFILE=contafin_oracle.dmp \
  LOGFILE=export_contafin.log VERSION=11.2
```

Copy to Windows:
```powershell
# Using SCP from WSL/Linux
scp root@10.0.20.201:/opt/oracle18/oradata/dmpdir/contafin_oracle.dmp C:\DMPDIR\
```

---

## Workflow Examples

### New Server Installation

```powershell
# 1. Install Oracle 21c XE (see docs/00-INSTALL-ORACLE-XE.md)

# 2. Configure
Copy-Item config.example.ps1 config.ps1
notepad config.ps1  # Edit values

# 3. Copy DMP files
mkdir C:\DMPDIR
Copy-Item \\server\dmp\*.dmp C:\DMPDIR\

# 4. Run setup scripts
.\01-setup-database.ps1
.\02-create-sys-objects.ps1
.\03-import-contafin.ps1
.\04-create-synonyms-grants.ps1
.\05-import-companies.ps1
.\07-verify-installation.ps1
```

### Add New Company

```powershell
# Copy company DMP
Copy-Item \\server\dmp\NEWCOMPANY.dmp C:\DMPDIR\

# Run add company script
.\06-add-company.ps1 -CompanyName "NEWCOMPANY" -Password "ROMFASTSOFT"
```

### Migration from Oracle 10g

```powershell
# 1. Export from Oracle 10g (on source Windows server)
exp system/password@ORCL file=C:\backup\COMPANY.dmp owner=COMPANY

# 2. Convert with Oracle 21c imp (if needed)
# Or use impdp with VERSION parameter

# 3. Import using scripts
.\05-import-companies.ps1 -DmpFile "COMPANY.dmp"
```

---

## Troubleshooting

### ORA-28040: No matching authentication protocol

**Problem:** Old clients (Instant Client 10/11) cannot connect to Oracle 21c.

**Solution:** Configure `sqlnet.ora` for backward compatibility:

```powershell
# Copy sqlnet.ora template
Copy-Item config\sqlnet.ora $env:ORACLE_HOME\network\admin\sqlnet.ora

# Restart listener
lsnrctl reload
```

### ORA-01017: invalid username/password

**After configuring sqlnet.ora for old clients, reset passwords:**

```sql
ALTER USER CONTAFIN_ORACLE IDENTIFIED BY ROMFASTSOFT;
ALTER USER [COMPANY] IDENTIFIED BY [PASSWORD];
```

### ORA-12514: TNS:listener does not currently know of service

**Check listener status:**

```powershell
lsnrctl status
lsnrctl services
```

**For XE, ensure PDB is open:**

```sql
ALTER SESSION SET CONTAINER = XEPDB1;
ALTER PLUGGABLE DATABASE XEPDB1 OPEN;
ALTER PLUGGABLE DATABASE XEPDB1 SAVE STATE;
```

### Import Errors

**ORA-00959: tablespace 'ROA' does not exist:**
```powershell
# Use REMAP_TABLESPACE in impdp
impdp ... REMAP_TABLESPACE=ROA:USERS
```

**ORA-39405: Oracle Data Pump does not support importing from a source database with TSTZ version newer:**

Use DMP files exported from Oracle 18c (TSTZ 31) instead of Oracle 21c (TSTZ 35).

### Service Not Starting

Check Windows Services:
- `OracleServiceXE` (for XE)
- `OracleServiceROA` (for SE)
- `OracleOraDB21Home1TNSListener`

```powershell
# Restart services
net stop OracleServiceXE
net start OracleServiceXE
net stop OracleOraDB21Home1TNSListener
net start OracleOraDB21Home1TNSListener
```

---

## Connection Strings

### SQL*Plus

```bash
# Oracle XE (connect to PDB)
sqlplus system/romfastsoft@localhost:1521/XEPDB1
sqlplus CONTAFIN_ORACLE/ROMFASTSOFT@localhost:1521/XEPDB1

# Oracle SE (connect to database)
sqlplus system/romfastsoft@localhost:1521/ROA
sqlplus CONTAFIN_ORACLE/ROMFASTSOFT@localhost:1521/ROA
```

### JDBC

```
# Oracle XE
jdbc:oracle:thin:@localhost:1521/XEPDB1

# Oracle SE
jdbc:oracle:thin:@localhost:1521/ROA
```

### ODBC (Instant Client)

| Parameter | XE Value | SE Value |
|-----------|----------|----------|
| Host | localhost | localhost |
| Port | 1521 | 1521 |
| Service Name | XEPDB1 | ROA |
| User | CONTAFIN_ORACLE | CONTAFIN_ORACLE |
| Password | ROMFASTSOFT | ROMFASTSOFT |

### TNS Entry

```
# For Oracle XE
ROA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA = (SERVICE_NAME = XEPDB1))
  )

# For Oracle SE
ROA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA = (SERVICE_NAME = ROA))
  )
```

## Testing with Proxmox VM Clone

For testing installations, use the VM cloning script:

```bash
# On Proxmox host (pvemini)
./test/clone-vm300.sh 301   # Creates VM 301 from template 300
```

See `test/clone-vm300.sh` for details.
