client configuration file
A file (in XML format) used by zPDT® to obtain parameters to access both an SHK License Server and a UIM server. It is at this location: /usr/z1090/bin/sntlconfig.xml .

A different client configuration exists for an LDK server.

A program (Linux® command) that can be used to change parameters in the client XML file.
A collection of z/OS® assets, such as volumes, data sets, CICS® resources, or DB2® resources, from an existing z/OS, z/OS instance, or the Extended ADCD package. A component is reusable with different components to create more than one image.
A component of ZD&T that emulates IBM Z® architecture with virtual I/O and devices on Intel™ x86-compatible platforms. It enables IBM® z/OS operating system, middleware and software for z/OS to run on Intel x86-compatible platforms without physical IBM Z platforms. It is intended for mainframe application demonstration, development, testing and education.
The ZD&T emulator is based on the IBM System z® Personal Development Tool (zPDT) program.
emulator instance
A ZD&T emulator instance provides a working environment that contains the z/OS core system as well as user-selected applications and z/OS subsystems in the target x86-compatible environment. Having multiple ZD&T emulator instances means that multiple independent ZD&T emulator environments are running in parallel.
A ZD&T emulator instance is also known as an emulated IBM Z environment (created by ZD&T).
Extended Application Developers Controlled Distribution (ADCD)
ZD&T Enterprise Edition also comes with the Extended ADCD package. The Extended ADCD package enables the enterprise users to use and develop their applications with the newest set of mainframe software packages, such as CICS, Db2®, IMS, z/OS, and JES2. You can select the software packages that you need, and provision the packages out of Extended ADCD to the target environment. For more information about Extended ADCD, see Extended ADCD reference.
IBM License Key Server
The license server used exclusively to share Rational® Token license entitlements among a set of IBM products.
IBM License Server
In zPDT, provides controlled access to multiple IBM software products and might be used along with zPDT license servers. The IBM License Server has no relation to zPDT license servers.
A serial number and instance number, as stored by the z Systems® STIDP instruction. The instance number is similar to an LPAR number on a larger z Systems.
A collection of components that are packaged together as a single deliverable. An image contains the z/OS core system and user-selected z/OS applications and subsystems. An image is used to provision z/OS instances on target environments.
A z/OS instance that is running on a target environment from a created image.
instance number
A number in the range of 1 and 255 assigned to each z/OS instance on a base Linux machine. Each z/OS instance must operate under a different Linux user ID and the instance number is assigned to the user ID. The instance number is used in the same manner as the LPAR number on a larger z Systems.
The product entitlement that you purchased and the corresponding terms and conditions under which use is allowed.
A technical indicator on the USB hardware device that is used to activate the hardware device and allow an emulated z Systems instance to operate. The zPDT Guide and Reference and the z Systems emulator messages use the words license and licenses to refer to these indicators stored on the hardware device. You can use a remote license server with the offering that derives its name from this particular usage of the word.
In the IBM License Key Center, a quantity of product entitlement parts purchased.
In zPDT, a logical function that enables one z Systems CP for a zPDT system. Multiple CPs require multiple licenses. The token functions provide licenses.
license entitlement
The IBM License Key Center interface and the quantity of entitlement parts purchased.
license key file
A file that represents the user’s license entitlement. License key files must be obtained, installed, and available to operate the product.
license monitor
A web browser interface that displays information about Sentinel Keys and clients that use them. It is accessed at port 7002 on a Linux system that runs a license server, but might not be functional on recent Linux distributions.
license server
The remote server that is set up to distribute authentication from a single high-capacity USB hardware device to remote instances of the product as an alternative to attaching discrete USB hardware devices to each computer that hosts one or more instances of the product.
The License Development Kit–Software License (LDK-SL) server that distributes software-based license keys without the need for a USB hardware device. This server is also referred to as a software-based license server.
The IBM License Key Server that is used to share license entitlements among several IBM products.
In zPDT, a network-accessible service that manages and dispenses zPDT licenses from a token or a “software-only” service. It operates as a Linux daemon and is automatically started (after it is installed) when Linux is started. A “local” zPDT installation internally accesses the license server through internal TCP/IP. Remote license servers are accessed through network TCP/IP.
local mode
A situation in which a remote license server and a UIM server are not used. zPDT obtains its serial number from the local UIM database. The client configuration XML file specifies localhost as the Contact Server. In local mode, the serial number might be a previously assigned number from a server or from a token. If an existing serial number is not present, the serial number is taken from the local token.
local to remote
A situation in which the serial number (in the local client database) was previously obtained from a local token, but zPDT is now configured to run with remote servers. If the remote license server determines that the serial number is valid and not being used elsewhere, that serial number is used.
product entitlement
The terms and conditions under which the product can be run by the license.
product license server
See license server.
provisioning tools
Refers to a web UI with role-based access control and REST APIs. The provisioning tools ease the process of provisioning and managing your z/OS instances. With either the web UI or REST APIs, you can perform tasks including but not limited to:
  • Extract artifacts, such as volumes and data sets, from existing IBM Z platforms to create components.
  • Transfer components to the storage server.
  • Build images from components.
  • Provision z/OS instances of selected images to target environments.
  • Manage and monitor components, images, and instances (also known as ZD&T emulator instances).
random serial number
A serial number that is unique, but is not tied to a token serial number. The UIM server generates and assigns these numbers. A random serial number can be used (by zPDT) with a license from any token. Do not take the “random” word too literally; in this case it means that tokens with serial numbers other than the one used to set the UIM serial number might be used. It does not mean you can select a random number.

Regarding serial numbers that are assigned from a token, in some cases (such as a “simple local system”) the z Systems serial number that is used by zPDT is taken from the token.

remote mode
The zPDT instance obtains licenses and UIM identification from a remote license server and UIM server.
remote to local
A situation in which the serial number was previously assigned by a UIM server (and stored in the local client UIM database) and zPDT is now being used without remote servers. In this case, the previously assigned serial number is used and the serial number of the local token (which must be present to provide a license) is ignored.
The company that provides the USB keys and the software that directly supports them. The software includes the USB driver, the Software-based License Server, and a web interface to the Software-based License Server. The owning company is now Gemalto N.V., but the SafeNet name is used with the products that are described in this documentation.
SafeNet Sentinel Key
The USB “token” from the SafeNet company. This token provides zPDT license information.
serial number
A value in the range of 1 and 65535 (4 hex digits). The serial number is assigned by the UIM function to the base Linux and used by zPDT to provide the z Systems serial number.
server configuration file
A file (in XML format) used by the SHK Sentinel Key Server to obtain networking and logging parameters. It is at this location: /opt/safenet_sentinel/common_files/sentinel_keys_server/Sntlconfigsrvr.xml
software-based license server
The remote ZD&T that distributes authentication by using software-based license keys.
See also license server.
software-based license server update file
The specific license key file that is generated in the IBM License Key Center and installed on a software-based license server by using an update_license command. This file is used for software-based licensing.
source environment
The environment where ZD&T users extract components.
Several types of source environments are supported, including z/OS on IBM Z physical hardware, Linux systems that run a z/OS instance, and Extended ADCD.
storage server
ZD&T Enterprise Edition stores extracted information on the intermediary storage machine, for example, FTP or SFTP server. Extracted information is never deleted from the storage server until the information is manually deleted, which enables you to provision as many as machines that you want based on your license entitlement. You need to prepare such a storage server and ensure enough storage on the storage server to hold the required artifacts.
target environment
An Intel x86-compatible environment that is capable of running one or more z/OS instances.
Several types of target environments are supported, including Linux, Docker, and Red Hat® OpenShift®.
time cheat
The Sentinel Key records the current date and time each time the key is accessed. If the Linux system clock contains a time earlier that the last recorded time in the token, the license is unusable.
See USB hardware device.
A type of IBM Rational product entitlement that allows great flexibility in the deployment and use of associated, purchased products. The product documentation uses the phrase Rational Token to refer to IBM Rational Token licensing.
In zPDT, another term for a SafeNet Sentinel Key. The terms token, key, SafeNet key, and Sentinel key are used interchangeably.
token serial number
The license information in the token contains a unique serial number that is assigned by IBM. This serial number might be used as the basis for the z Systems CP serial number in some cases.
UIM client
Each Linux machine that runs zPDT has a client function. In a local operation, a remote UIM server might not be involved. The UIM client might operate solely from the local UIM database.
UIM database
A file that contains UIM information. The files are not directly editable. UIM databases are of two types. One exists in every Linux zPDT machine, and the other exists in a UIM server (if it is used). The local database (on a zPDT client) is at this location: /usr/z1090/uim/uimclient.db.
UIM or unique identification manager
A server (or local function of zPDT) that helps maintain unique enterprise-wide z Systems serial numbers for zPDT systems. The license server and the UIM server (or local function) are separate but parallel functions.
UIM server
A centralized service that maintains unique zPDT serial numbers for multiple zPDT machines within an enterprise. Clients access the server through TCP/IP. The server runs under a normal Linux user ID (and not under root).
update file
The specific license key file that is generated in the IBM License Key Center and applied to the USB hardware device to enable zPDT operation.
USB hardware device
The device that is required by ZD&T to operate the product. The zPDT Guide and Reference and z Systems emulator messages use the words token and tokens to refer to these hardware devices. In such places, you can find further reference to the 1091 token that is intended for use with the ZD&T offering.
USB hardware device activation
The condition of the hardware device and its readiness for operation with the emulator.
USB server
A driver that is provided by SafeNet to access tokens on USB ports. It operates as a Linux daemon and is installed when zPDT is installed.
A universally unique identifier. It is obtained from the Intel machine BIOS. It is used to uniquely associate a UIM serial number with a particular machine.
web server
A server that enables ZD&T provisioning tools. It is a component of ZD&T Enterprise Edition.
The web server can be installed on the same system as the hardware-based license server or as the software-based license server.
ZD&T z/OS Extraction Utilities
A component of ZD&T Enterprise Edition to be installed on one or more IBM Z platforms to allow ZD&T to use such IBM Z platforms as source environments to extract z/OS, CICS, and Db2 resources.
Installation of ZD&T z/OS Extraction Utilities is required only if you need to create components from either the physical or emulated IBM Z platforms.
The IBM System z Personal Development Tool (zPDT) provides an environment with one or more IBM System z processors (with several emulated I/O device types), based on a personal computer Linux environment. As the name implies, it is intended for development and related purposes, such as education and demonstrations.
