CA Gen / COOL:Gen modernization — from 3270 screens and action blocks to cloud-native microservices and Angular. INSURE-CLAIM: 5 procedure steps, 5 BMS screens, 4 action blocks, DB2 backend.

🔍 Discovery Scan

SOTERIA ingests CA Gen artifacts + generated COBOL — maps the full INSURE-CLAIM estate

📊 Assessment

Dependency graph, business rule catalog, ICLSC040 divergence hotspot identified

⚙️ Transform Action Block

CA Gen action diagram → generated COBOL → Java Spring Boot via APPDATE

📋 Business Rules

6 rules from ICLSC040.cbl — including 2008 direct patch to deductible calc

✅ Run Validation

Business parity tests across 6 BR rules — Docker-compose local stack

✨ ReImagine 3270 → Angular

5 BMS screens → single Angular stepper with live calc panel and auto-approval badge

CA GEN / COOL:GEN · INSURE-CLAIM → JAVA MICROSERVICES + .NET CORE 8

Findings

History

Export

Assessment Findings — INSURE-CLAIM

Critical · Artifact Sync Drift

ICLSC040.cbl lines 445–512 patched directly in 2008 — CA Gen model does NOT reflect the live deductible calculation. Running COBOL is ground truth.

Warning · COMMAREA State

DA-SESSION-CTX and DA-CALC-RESULTS passed via CICS COMMAREA across 5 PSteps — mapped to Spring @SessionScope beans + REST request chain.

Warning · Range Scan Hotspot

ICLSC040.cbl duplicate-check scans CLAIM_T with 30-day date range and no index hint — APPDATE adds composite index on (POLICY_ID, INCIDENT_DATE).

Info · DB2 Sequence

CLAIM_SEQ DB2 sequence in ASSIGN-CLAIM-NUMBER → PostgreSQL SEQUENCE claim_id_seq. Claim ID format CL-YYYY-NNNNNNNN preserved exactly.

Info · BMS Field Attributes

5 BMS maps with protected/unprotected/numeric fields → Angular reactive form validators. PF key navigation → stepper buttons + keyboard shortcuts.

OK · Business Rule Parity

6/6 business rules verified by KÍRKĒ parity tests. BR-003 auto-approval ($4,200 medical → $2,960 → AUTO-APPROVED) confirmed passing.

OK · Exit States → REST

CA Gen exit states (POLICY-FOUND, VALIDATION-PASS, DUPLICATE-DETECTED) → typed ResponseEntity envelopes with HTTP 200/400/409 semantics.
