zPDT 2016 Sysplex Extensions

Book Description

This IBM® Redbooks® publication describes the IBM zPDT® 2016 Sysplex Extensions, which is a package that consists of sample files and supporting documentation to help you get a functioning, data sharing, sysplex up and running with minimal time and effort.

This package is designed and tested to be installed on top of a standard ADCD environment. It provides the extra files that you need to create a two-way data sharing IBM z/OS® 2.1 sysplex that runs under ADCD in a zPDT environment.

This package differs from the previous zPDT sysplex package in that it provides working examples of more sysplex exploiters. It also is designed to adhere to IBM's sysplex best practice recommendations, in as far as is possible in a zPDT environment.

Although the package was not tested with IBM Rational® Development and Test for IBM System z® (RD&T), it might be used to reduce the effort to create a fully functional sysplex under RD&T.

Conceptually, the package might also be restored and used as a template to create a sysplex environment that is running on a real IBM z™ Systems CPC.

The target audience for this document is system programmers that are responsible for designing, creating, and maintaining IBM Parallel Sysplex® environments. It can also be beneficial to developers that currently maintain their own ADCD environments and want to extend them to add sysplex functions.
