Independent Software Vendor IBM Z® Program Development Tool (ISV zPDT)
ISV zPDT, formerly known as zPDT, provides IBM zSystems™ functions and associated utility programs to a particular set of independent software development companies. It uses a personal computer (PC) running under Linux® to emulate an IBM zSystems mainframe for software development and testing purposes.
ISV zPDT itself does not include any IBM zSystems or operating systems. To be able to emulate them, you will need a subscription to the IBM Software stacks, also known as Application Development Controlled Distribution (ADCD).
ISV zPDT is licensed for software development and some
basic software testing. It is not licensed or appropriate as a
production system. Meaning that ISV zPDT is not valid
for application "production" or performance measurement usage.
Such usage would violate the licensing agreements for the
zPDT product, the IBM zSystems operating system, and other
IBM licensed products, including other licensed software
used on IBM zSystems.
