RD&T Overview


RD&T Overview

• IBM z/OS® on developer desktop or shared server. • It provides a test environment for mainframe

applications • It uses a virtual IBM System z environment• It includes

– Application development and testing tool– Mixed workload support– Software support and integration

• Can have RDz run with RD&T– Execute/Run on RD&T


Typical RD&T Challenges

• Linux and Z/OS experience

• Understanding of RD&T environment

• Mapping definitions between Linux & Z/OS

• Network connectivity

• Ongoing administration

• Synchronization of programs and data with Mainframe.


Royal Cyber RD&T offerings

• Installation Support

• Configuration and Setup Support

• Proof of Concept

• Data migration support

• Reduced startup costs with ‘Jumpstart’

• Training delivery and after sales support


Customer Case Study


Development Environment

• 2 LPARs – Production & Development/Test

• COBOL, ASSEMBLER.

• Enterprise COBOL 4.2 for System z.

• ~7000 CICS and ~20000 Batch applications supported by 10 developers

• No SCM – Use PDS libraries with in-house procedures.


Customer’s Requirements

• Control MIPS on mainframe– Offload development and testing activities off mainframe

• Advanced features of debugging tools to assist developers and testers

• Implement Source Control Management System

• ROI through MIPS savings

• Ability to attract young crowd to work on mainframe development

DEVELOPMENT SHIFTED TO RDT


Agreement and Approach

Phase I• RD&T

– Install, configure, customize, train• Move development data to RD&T for unit test • Provide RD&T user administration and support training

Phase II• Implement RDz• Train on RDz and Debug Tool• Implement and train on File Manager


RD&T Install steps - 1

• Install and configure openSUSE Linux to run the z1090 emulator• Install and activate the z1090 emulator• Extract volumes to be used with the z1090• create new volumes to be used with the RD&T system so as to match the

customer's host environment• Configure the z/OS running on z1090. • Modify procs, parmlibs, create users, modify security as per the

customer's specifications• Configure products and middleware running on RD&T (CICS, DB2, IBM

Debug Tool)


RD&T Install Steps - 2

• Data migration from the host to the RD&T system. The following artifacts were migrated:– VSAM & non-VSAM files – CICS CSD– DB2 tables and other structures (views, synonyms ..etc)– Security structure

• Train Staff on using, managing and administering RD&T– Linux commands– IPL and shutdown Sequence– Data migration


Problem 1 – Support for Linux on VMWARE

Manual says: “Running under a hipervisor, such as VMware or Xen or KVM, is not supported at this time. …. We do not provide specific instructions for virtual environments and you must determine how to configure a USB port (for the token) and Ethernet ports for their particular virtual hipervisor.”

And the customer wanted Linux on VMware …


Solution 1 – Support for Linux on VMWARE

• Tested VMware setup on our environment

• Advised the customer on preferred configuration for performance

• Initially, license USB token did not work– Configured Linux Image to use hardware port

• Provided instructions for VMWARE departure from documentations.


Problem 2 – DASD Volume Move utility

• RD&T DASD Migration Utility – zPDTMSRV, hckd2ckd

• Client-server utility for moving 3380/3390 volumes from a remote z/OS or z/VM system to zPDT.

• The server portion of this utility runs under z/OS or z/VM on the remote System z.

Mainframe RD&T


Solution 2 – DASD Volume Move utility

• Identify Datasets needed through HLQ and dataset names

• Use DFDSS utility to logically dump the datasets using filtering

• Set up RD&T with USERCAT, Volumes and Alias definitions

• Transfer the dump file to RD&T

• Restore dump to volumes

• Balance volume usage as needed.

Problem 3 - Data Synchronization

• Customer specific• Best route we provided is total refresh• Baseline can be maintained either on mainframe or RD&T depending

on needs• DFDSS dump/restore with replace can be used.


Solution 3 - Data Synchronization

• RD&T system is unit Development & Test• RD&T Data is ‘Baseline’.• Refresh mainframe ‘production’ copy with project releases• Use DFDSS dump/restore with Filtering


Data Synchronization Scenarios

1. RD&T is Unit Test only • Mainframe data is ’Baseline’• Refresh RD&T data using DFDSS dump/restore

2. Customer DASD Volumes are application specific (or can make them)• Use Volume dumps. Volume to include user catalogs.• Use IDCAMS import connect


Live Demo


Royal Cyber RD&T skills• Installation and configuration of Linux based machines/servers on which RD&T

runs• Installation and configuration of the z1090 emulator on Linux• Replication of the host mainframe environment on the RD&T system:

• Volume and data migration from the host mainframe to the RD&T system. (VSAM, DB2, CICS)

• Migration of programs and utilities from the host mainframe (ISPF, REXX, CLIST)• Complete customization of the z/OS installed on the RD&T system- user profiles,

data, programs, products• Installation and configuration of various IBM and 3rd Party products on RD&T (For

example, Websphere Application Server, Websphere MQ, IBM Debug Tool, Rational Team Concert, Websphere Portal, Rational Developer for System z, CA Endevor, etc.)

• Maintaining the RD&T system to be current with the changes on the host mainframe – customizing solutions

• Training system administration staff on RD&T installation, configuration, and maintenance.
