VRX zMigTSS — Top Secret ➜ RACF (Automated REXX Utility for Migration)
Discovery & Extraction • REXX collectors for TSS LIST / WHOOWNS / ACID extract ACIDs, DEPT/ZONE, resource rules (DATASET, FACILITY, LPA, APPL, DB2, CICS, TCP), ownership, and expiry details • Outputs TSS data (LIST/WHOOWNS/ACID) to a flat file Normalization & Mapping • Rule engine maps TSS to RACF: o ACID → USER/GROUP (DEPT/ZONE → RACF group hierarchy) o TSS PERMIT → RACF PERMIT (translates access levels; handles FORCE/INHIBIT) o FACILITY/RESOURCE → RACF CLASS (e.g., FACILITY(TSSCMD) → CLASS(FACILITY) PROFILE(TSSCMD)) Transformation Phase (TSS ➜ RACF) • Map zones/divisions/departments to RACF groups • Convert users and access levels to RACF USER/GROUP relationships • Map Control IDs to RACF attributes (SPECIAL, OPERATIONS) • Convert TSS resource rules to RACF classes/profiles with correct UACC and masking Command Generation & Load (TEST ➜ PROD) • Generates audited RACF commands (ADDUSER, RDEFINE, PERMIT, SETROPTS) with dry-run diffs Validation & Reports • Synthetic access tests simulate ACID access on mapped RACF profiles • Parity diff reports highlight missing profiles, UACC mismatches, excessive permits, and orphan users • Validates access and parity integrity ________________________________________ Benefits (with Metrics) • 85–95% faster migration (e.g., 20,000 permits in 3–5 days vs 4–6 weeks) • ≥99.9% rule parity with 0 Sev-1 authorization failures at cutover (SLO) • 50–70% reduction in over-permissive grants (tightened UACC, improved SoD compliance) • 30–45% reduction in effort/cost (minimal manual work, fewer dual-skilled SMEs) • Fully audit-ready: signed CSVs, command logs, parity and rollback packs
Before You Modernize, Know What You Own
Mainframe asset assessment helps organizations identify unused software, eliminate waste, and optimize operational costs before modernization begins.
Data-driven insights lead to smarter IT planning, better resource utilization, and more successful transformation strategies.
Modernization starts with visibility and clarity.
