Marius 31c4065bd2 fix(roa): aliasul TNS lipsea din Oracle Home, iar actualizarea esua tacut 
Constatat la VADECO pe 2026-08-28: pe serverul acela actualizarea ROA nu
aplicase NICIODATA un script, desi jobul raporta succes de la instalare.

PACK_UPDATE nu aplica el scripturile - genereaza D:\DMPDIR\script_master.sql
si lanseaza un sqlplus EXTERN, apoi se termina. Deci UPDATEROA_ZILNIC
raporteaza starea lansarii, nu a actualizarii: SUCCEEDED in ~5 secunde chiar
si cand nu s-a aplicat nimic. Scriptul generat incepe cu
"CONNECT CONTAFIN_ORACLE/...@ROA" (aliasul vine din NOM_FIRME.NUME_SERVER)
si are WHENEVER SQLERROR EXIT, deci iese la prima linie daca aliasul nu se
rezolva.

Lantul cauzal: sqlplus-ul lansat de baza mosteneste mediul serviciului
Oracle. La o instalare noua instanta porneste INAINTE ca 01-setup-database
sa scrie TNS_ADMIN de masina, deci serviciul nu il are si cade pe
tnsnames.ora din Oracle Home. La 21c XE home-ul e read-only, deci fisierul
real e in product\21c\homes\OraDB21Home1\network\admin, iar acolo Oracle
genereaza doar XE, LISTENER_XE si ORACLR_CONNECTION_DATA - fara ROA.
Rezultat: ORA-12154, tacut. Perfid: tnsping ROA REUSESTE dintr-o sesiune
interactiva, pentru ca aceea are TNS_ADMIN.

Eroarea era mascata dublu - jobul zicea SUCCEEDED, iar emailul de raportare
nu pleaca oricum (ORA-29279, SMTP-ul romfast nu anunta AUTH).

01-setup-database.ps1 scrie acum aliasul si in tnsnames.ora al Oracle
Home-ului, cu acelasi IP din LAN. Blocul se IMBINA in fisierul existent:
XE, LISTENER_XE si ORACLR_CONNECTION_DATA raman neatinse, pentru ca de ele
depind extproc si inregistrarea instantei la listener. Cu backup si
idempotent - regexul consuma si comentariile lipite deasupra lui "ROA =",
altfel antetul se dubla la fiecare rulare (prins de test).

Testat unitar (fisier Oracle fara ROA, idempotenta peste 4 rulari, ROA
preexistent cu alt IP la mijloc, fisier inexistent, paranteze echilibrate,
fara BOM) si end-to-end pe o copie a fisierului real de pe serverul VADECO:
tnsping ROA OK, sqlplus CONTAFIN_ORACLE@ROA conectat in XEPDB1, zero ORA-,
XE si LISTENER_XE inca se rezolva.

docs/lectii-actualizare-roa-alias-tns.md are diagnosticul complet, inclusiv
cum verifici ca actualizarea chiar s-a aplicat: script_master.log si
SCHEMA.versiune, NU statusul jobului. Contine si capcana ca randurile din
SCHEMA.versiune vin cu dump-ul la import, deci o schema proaspat importata
pare la zi fara ca actualizarea sa fi rulat vreodata local.

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
ROMFASTSQL is an infrastructure and database management project for ROMFAST, featuring:
- Proxmox virtualization cluster (3 nodes: pve1, pvemini, pveelite)
- Oracle Database XE 21c with migration support from Oracle 10g
- AI chatbot system (Flowise + Claude)
- Disaster recovery infrastructure

## SQL Migration Conventions
When writing Oracle migration scripts, follow the naming convention:
```
ff_YYYY_MM_DD_##_TYPE.sql
```
Where TYPE is: DDL, DML, VIEW, PACK, TRIG, etc.
Always reference `system_instructions/system_prompt.md` for:
- Oracle 10g compatibility requirements
- PACK_MIGRARE package usage
- Migration script patterns and examples
## Custom Claude Code Commands
- `/ultimate_validate_command` - Generate comprehensive validation commands
- `/plan-handover` - Save implementation plan for session handover
- `/branch-plan-handover` - Create branch and save plan
- `/context-handover` - Save context for next session
## Git Workflow
- Remote: `http://gitea:3000/romfast/ROMFASTSQL.git`
