MIRA Codex Studio

NATURAL/ADABAS → Java Spring Boot + Angular modernization. SERPRO SIAR: K33310 library, 22 programs, 39 3270 maps, 4 ADABAS files (180K+ records) — real-time WebSocket/STOMP session architecture.

🔍 Discovery Scan

SOTERIA ingests K33310 library — 22 NSP programs, 39 NSM maps, 4 ADABAS DDMs

🔌 Architecture

REPEAT/INPUT loop semantics → persistent WebSocket/STOMP session per client

⚙️ Transform

NSM maps → Angular components · NSP programs → Java · ADABAS → PostgreSQL

✅ Validate

Cypress e2e: login → menu selection → ENTER → REINPUT → PF3 terminate

🚀 Deploy

Multi-stage Docker, docker-compose, K8s with sticky-session WebSocket Ingress

✨ ReImage

3270 terminal grid vs Brazilian gov.br Design System — side-by-side visual comparison

🎨 SDLC

gov.br DS-GOV compliant upgrade — TS component + HTML template + visual side-by-side

⚡ Alternative Architecture

Customer blocked WebSocket — REST + Redis replaces STOMP, frontend owns session state

Findings

History

Export

Assessment Findings — SIAR K33310

Critical · ISN Dependency

ADABAS Internal Sequence Numbers used directly in application logic (#M03-ISN in L3331001.NSL). Requires ISN-to-UUID mapping table before PostgreSQL cutover — not a direct column rename.

Critical · Native ASM Code

ONBSORT.ASM, ONDATAHO.ASM, ondvmodg.c — three non-NATURAL native modules called via CALL/CALLNAT. Requires C JNI wrapper or pure Java reimplementation of sort and date routines.

Warning · 900-Element Arrays

#M3331003-IMAGEM-TELA (1:900) holds paginated screen state in-memory. With 2 replicas, sticky sessions required — implemented via Ingress ip_hash annotation.

Warning · Date Redefines

REDEFINE #DA-NORMAL maps AA/MM/DD to DD/MM/AA — non-standard date inversion logic replicated in DaInvertidaRed.java with @FieldMetadata offsets.

Info · ADABAS File Sizes

AA-REMESSAS-SIAR: 180,251 records · AA-TABELAS-SIAR: 345 · AA-REGISTROS-REJEITADOS: 7,313 · AA-REMESSAS-PARCIAL: 3,792. PostgreSQL migration: ~190K rows total.

OK · Map Portability

All 39 NSM maps successfully transpiled to Angular components. Grid-based CSS preserves 80-column terminal layout semantics during transition period.

OK · IONATE Engine Coverage

22/22 NSP programs transpiled via IONATE runtime engine. DECIDE ON → switch, FIND → JPA, PERFORM → method call, CALLNAT → ReflectionUtils.
