FA-0508Mainframe & Enterprise Systems

Abend-AID Foundations

Effective Mainframe Failure Resolution - 2 days

Introduction

Why this course

Abend-AID has remained one of the most trusted tools for mainframe teams who need to understand failures quickly and precisely. Modern systems may be complex, but the fundamentals of disciplined fault-analysis have not changed, and Abend-AID continues to give developers the clarity they need when a job, transaction, or subsystem goes off-track.

This course brings together practical field knowledge, long-standing diagnostic techniques, and the latest capabilities of the tool, offering a grounded path for anyone who wants to strengthen their debugging workflow. With instruction shaped by more than three decades of real industry experience, participants move beyond theory and learn how Abend-AID is actually used to resolve production issues with confidence.

Learning outcomes

By the end of this training, participants will be able to:

Navigate Abend-AID reports (batch, CICS, Db2) and interpret key sections.
Use Abend-AID to identify root causes of application/system abends including S0C/SOC codes.
Perform fault-analysis for COBOL/CICS/IMS/Db2 environments using Abend-AID.
Integrate Abend-AID into their troubleshooting workflow to reduce mean-time-to-repair (MTTR).
Apply best practices for configuring and using Abend-AID (viewer access, hot-keys, filters) in their mainframe operations.

Prerequisites

Basic understanding of mainframe terminology: z/OS, TSO/ISPF, JES, CICS, Db2.
Familiarity with COBOL (or other mainframe languages) and typical abend codes (e.g., S0C7, S0C4).
Access to or interest in access to a mainframe / test environment (or simulation) where Abend-AID is installed.
Comfortable working in remote environments (since many organisations now use remote/test setups) — your Linux/SSH/VS Code workflow fits well.

Training outline
