zPDT features and functions


The IBM System z® Personal Development Tool (zPDT) consists of software (product number 5799- ADE) that is authenticated by a USB hardware key (product number 1090-L01, -L02, or -L03). The zPDT creates a System z environment allowing mainframe operating systems, middleware, and software to run unaltered on x86-compatible platforms. The zPDT enables qualified PartnerWorld independent software vendors (ISVs) to develop software for the System z platform without the need for System z hardware for development purposes.

zPDT is not designed to run an environment equal to that of a true System z platform. Many aspects of a larger z platform are not available on zPDT. These include the ability to verify and enhance the scalability of a program under development or run application programs that require hundreds of MIPS. A larger System z is needed for these areas of development and test. Likewise, a zPDT system is not recommended for very fine-level performance tuning that is sensitive to memory location, cache functions, and pipeline optimization. Larger System z machines have different characteristics than a zPDT at this level. In addition, the zPDT platform does not have the same quality of service of a mainframe in terms of availability, connectivity, or hardware protected cryptography. The zPDT environment is not intended to be a full replacement for a larger scaled mainframe development system.

zPDT functional support

The zPDT creates a virtual System z architecture environment, with virtual I/O and devices as well. Some of the features for zPDT:

New for zPDT 1.4 (available 12/14/12)

zPDT Base

NOTE : System z functions not supported by zPDT are as follows:

User interfaces

The most basic interface for most zPDT users are "local" 3270 terminals running in Linux windows. A TN3270 or TN3270E emulators is needed, and the x3270 program suite (available with many Linux distributions) is commonly used. These 3270 terminal windows provide traditional operator consoles and user sessions.

OSA provides Ethernet TCP/IP connectivity to the System z operating system and can be used for remote or local TN3270 or TM3270E, Telnet, Secure Shell(SSH), and so on connections.

Migration utilities

z/OS data migration utility (a client/ server application) allows simplified migration of z/OS 3380 and 3390 volumes to the zPDT-based system essentially helping you to clone a big z/OS system to the zPDT-based system.

z/VM data migration utility (a client/ server application) allows simplified migration of z/VM 3380, 3390, and FBA volumes to the zPDT-based system essentially helping you to clone a big z/VM system to the zPDT-based system.

zPDT performance

IBM does not provide specific performance numbers for zPDT, in MIPS, million service units (MSU), or large system performance reference (LSPR) metrics. Performance varies according to:

Suggested IBM software pricing metrics for the three sizes of zPDT are available upon request. Metrics are for IBM software pricing purposes and not an indication of zPDT speed or size.
