Complete Mainframe Solutions - Z/XDC, AuthXDC & DumpXDC

One Suite. Three Specialized Solutions.

Complete Visibility Across Your Entire IBM Z Environment

The XDC suite is designed to give you complete debugging capabilities across the entire application lifecycle. Whether you're actively developing new code, troubleshooting authorization issues, or analyzing production dumps, our integrated tools provide the visibility you need to work efficiently and deliver with confidence.

Reduce debugging time by 35-45%
Accelerate modernization initiatives with confidence
Resolve production issues faster with source-level clarity
Support all major z/OS languages and environments

Z/XDC gives you complete, source-level visibility into running programs across any z/OS environment. Step through code as it executes, inspect variables in real-time, set conditional breakpoints, and seamlessly move between Assembler, C/C++/MetalC all in a single debugging session.

AuthXDC provides real-time visibility into authorized or user-constrained environments and enables development and support teams to efficiently diagnose and resolve issues in systems where security or system restrictions require specialized handling.

DumpXDC transforms raw system dumps into clear, source-level views of your program's state at failure. Working seamlessly with IPCS, it gives you the same powerful Z/XDC commands you use during development—but applied to production dumps—so you can diagnose and resolve issues without reproducing them.
