: You must have a zPDT or zD&T system installed on a Linux host.
The world of mainframe computing often feels like a walled garden, accessible only to those within large corporations. However, for developers, systems programmers, and enthusiasts, the has long been the bridge between high-level enterprise architecture and personal hands-on learning. Specifically, version z/OS 1.13 remains a significant milestone in the evolution of IBM’s premier operating system. What is z/OS ADCD?
The "1.13" in ADCD 1.13 refers to the underlying operating system version: . Z Os Adcd 1.13 - 13
When booting (IPLing) the ADCD 1.13 system, you must select the correct to define your environment: CS : Cold Start (initializes clean). WS : Warm Start (restores previous state). CL : Specifies a Console address.
ADCD is a customized bundle of z/OS and related middleware products. It is specifically designed to run on the , a software emulator that allows mainframe environments to run on standard x86 PC hardware. : You must have a zPDT or zD&T
The system also had pre-defined procedures to manage system logs. It was configured to clear SMF data using a procedure called SMFCLEAR , triggered by the IEFU29 exit routine. For those who wanted to save SMF data, a straightforward modification to this routine was documented in the official guide.
Unlike a standard z/OS production installation, which takes weeks of custom Systems Programming (SysProg) effort to configure via System Modification Program/Extended (SMP/E), ADCD arrives as a "ready-to-IPL" (Initial Program Load) software package. Specifically, version z/OS 1
: This distribution is often integrated with IBM Rational Development and Test Environment for System z , which uses zPDT as its underlying technology. Included Software and Tooling
This edition saw the exciting inclusion of , which was pre-configured to start up automatically using the CI LOADPARM. Concurrently, CICS V4.1 was removed from the base package, though it remained available as a separate download.
