Version GA10 z1090-1-10.55.16 Release Letter


1. Product Description

The IBM System z Personal Development Tool (zPDT) provides System z functionality, with selected emulated I/O devices. The z1090 runs in a Linux environment.  As the name implies, a zPDT is intended for development and similar purposes such as education and demonstrations.  It lacks the Reliability and Service (RAS) and flexibility of a “real” System z machine and is not suitable for production use. This release letter refers to the zPDT that uses a token or USB hardware key defined as a Sentinel Hardware Key (SHK) for licensing management. Please reference the System zPDT Guide and Reference (SG24-8205-05) Redbook, section 1.3 Terminology changes for more information concerning licensing options.

2. New Function

PLEASE read the Addendum , section “NEW TOKENS” in this document.

3. Fixed in this release


4. System Configuration and Prerequisites

The supported levels of Linux must be at least the 64-bit version of Red Hat Enterprise Linux (RHEL) 7.0 or greater, the 64-bit version of openSUSE Leap 42.3 or greater, the 64-bit version of SLES 12 SP3 or greater, and Ubuntu 16.04 or greater. Earlier versions are not supported.


5. Install z1090-1-10.55.16

If you are installing the 1090 application for the first time, refer to the Redbook titled IBM zPDT Guide and Reference System z Personal Development Tool (SG24-8205-05), chapter five, zPDT Installation. Please be sure that you have installed the appropriate version of Linux and the prerequisites before proceeding to install the 1090 code. If you have already installed the appropriate version of Linux and the required prerequisites, and you are upgrading from a previous zPDT level, please proceed to the next step.


5.1. Install the 1090 application

You will use root to install the z1090 release. As root, install z1090-1-10.55.16.x86_64 and accept the End User License agreement. If you’ve downloaded the release, set the proper write and access permissions (either chmod 755 or u+x zPDT package name).


5.2. Execute z1090instcheck

The next step is to run the command z1090instcheck to check if conditions of your system are favorable for the 1090 application. You should run this command from the user login configured to run the 1090 application. If you choose to run from root, the path is /usr/z1090/bin/z1090instcheck.


5.3. Plug the Sentinel Hardware Key (SHK)

If not already plugged in, be sure to plug the SHK into the appropriate USB slot. If this is a brand new SHK that has not been activated yet, you’ll need the 1090 code to be able to activate the SHK. The SHK may be plugged into any available USB 2.0 port. If you are planning to install the SHK in a USB hub make sure that the hub is externally powered, otherwise, you could damage the SHK.


6. 1090 Directory Structure

The following is the directory structure set up by the install process. If the structure is not in place, the awsstart command will create it for you.


/<homeDir>/z1090/logs various traces are placed here

/<homeDir>/z1090/configs IOCDs, IOCP, activation profiles

/<homeDir>/z1090/disks emulated disk volumes

/<homeDir>/z1090/tapes emulated tape volumes

/<homeDir>/z1090/cards input to emulated card reader

/<homeDir>/z1090/list emulated printer output


(where /<homeDir> is whatever the home directory is for the given user)

Addendum


NEW TOKENS:

The IBM 1090 license tokens have been an important part of zPDT since it was

released. The technology involved with these tokens has aged and zPDT must

switch to new tokens. The general plan is to require the use of the new tokens

when renewing a zPDT license, starting in the fourth quarter 2023. Since licenses are generally good for a year, this should result in all users having new tokens by the end of 2024. zPDT will support both the old tokens and the new tokens for at least a year.


The handling of IBM 1091 license tokens used by some ZD&T customers will

be addressed in the future. The software-only ZD&T licenses will not be replaced and will continue to be used.


As a general plan, the Information Technology Company (ITC) will handle the actual distribution of the new tokens. ITC will provide suitable documentation and forum notes. Depending on the customer situation, there might be a minor fee to cover the actual cost of the new tokens. The new tokens are USB devices, slightly smaller than the previous tokens, and have IBM model numbers such as 1090-LT1, 1090-LT2, and so forth.


There are only a few technical changes involved in using the new tokens. For

example, request_license and update_license commands replace the previous

Z1090_token_update command. The query_license command has been expanded to include details about the new tokens. Some IBM and ITC documentation uses the terms Gen1 (for the older SHK tokens) and Gen2 (for the new LDK tokens); this terminology was created a few years ago and these are simply convenient names with no special meanings.


For the newer (Gen2) 1090 tokens, do the following:
