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):

# 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:

# 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

# 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

# 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

# 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"

---

Uninstall / Cleanup

To remove all ROA objects and start fresh (useful for testing):

# Interactive (with confirmation)
.\scripts\99-uninstall-roa.ps1 -SystemPassword "romfastsoft"

# Force (no confirmation)
.\scripts\99-uninstall-roa.ps1 -SystemPassword "romfastsoft" -Force

Or run the SQL script directly:

sqlplus sys/romfastsoft@localhost:1521/XEPDB1 as sysdba @sql/uninstall-roa.sql

This removes:

• All company user schemas (using ROA tablespace)
• CONTAFIN_ORACLE user and all objects
• Public synonyms pointing to CONTAFIN_ORACLE
• SYS custom objects (AUTH_PACK, AUTH_SERII, INFO, etc.)
• Application context SESIUNE
• Tablespace ROA (including datafile)

Warning: This permanently deletes all ROA data! Use only for testing or before reinstallation.

---

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:

# 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:

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:

lsnrctl status
lsnrctl services

For XE, ensure PDB is open:

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:

# 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

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

Testing with Proxmox VM Clone

For testing installations, use the VM cloning script:

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

See test/clone-vm300.sh for details.
