2 Technical Root Cause & Architecture Mechanics
3 Step-by-Step Diagnostic & Code Resolution
Diagnostic Reference Matrix
| Attribute | Diagnostic Specification |
|---|---|
| Target Subsystem | IBM z/OS 2.4 - 3.1 • DevOps & Automation |
| Error Signature | Zowe CLI, VSAM, Python |
| Resolution SLA | < 15 Minutes via Verified StackMF Runbook |
| Technical Reviewer | Anshu, Chief Technology Architect • StackMF Architecture Pod |
Architectural Prevention & Performance Tuning Checklist
- Use `--type LIBRARY` (PDSE) instead of classic PDS to avoid directory block exhaustion.
- Automate teardown of temporary test datasets after CI/CD test suite completion.
- Verify that dataset high-level qualifiers (HLQs) conform to RACF dataset profile conventions.
