The RD&T Feature consists of:� Unit Test Environment (based on zPDT)

� Unit Test Environment can provide a System z development platform on a PC

� capable of running z/OS� provides great flexibility to run a customized

environment

� Software stack provides a choice of IBM middleware test environments� actual middleware software (including z/OS)� actual enterprise compilers� no API simulation

� RDz and RTCz agents � packaged for simplification� still need RTC and RDz client license(s) to

activate

31


� The RD&T environment does NOT support all System z function, such as:• Physical Parallel, ESCON®, FCP, FICON®

and High Performance FICON channels • Coupling links and coupling facilities• List-directed IPL• External Time Reference (ETR) • Server Time Protocol (STP)

RD&T limitations

• MIDAWs• Logical channel subsystems• HiperSockets™

• Multiple I/O paths per device• Not all CHSC functions are supported• Some IBM System z Crypto Express2• Some IBM 3088 CTC device

� RD&T does not produce an environment equal to a larger System z. • Some aspects of a larger system are unlikely to be met in any very small environment.

• Inability to verify and enhance the scalability of a program

• Inability to run application programs that require hundreds of MIPS.

• A UT system is not recommended for very fine-level performance tuning that is sensitive to memory location, cache functions, and pipeline optimization.

• In addition, the UT platform does not nearly have the same quality of service as does a mainframe in terms of availability and connectivity.

� Anyone needing any of the function outlined above should consider a traditional System z server.


Top 5 Questions� 1) What is the maximum number of developers a RD&T server can support?

This can vary depending on the underlying hardware and workload being tested. Desktop/Laptops can typically support 3-5 users. Low end server class machines can support 15-30 users. At this time, IBM has not provided a detailed analysis of RD&T server sizing.

� 2) How can I get test data for use in RD&T?

Customers can use existing tools like IDCAMS, DB2 utilities, etc. to extract test data and then download it to the RD&T machine. RD&T provides a volume duplication utility that can download an entire 3390 data volume as needed into the UT environment

� 3) Can I run other levels/backlevels of the middleware provided?

Not currently. This is being investigated to determine whether this capability could be provided in the future.

� 4) Can I use other IBM tools in the RD&T environment?

ESW zOTC or zMLC tools (like PD tools) cannot currently be used. There is no mechanism for IBM to license the software to the UT environment. Passport Advantage products can be used in the RD&T environment. We are investigating providing this capability in the future.

� 5) Can I run third party software?

Yes, if the third party license allows this. Customers must work with their software vendor to determine licensing considerations.


Additional Questions� 6) Does this require system programming skills?

� z/OS does require system programming skills to set up the development and/or testing environments.

� You can usually set up one box and transfer the configurations to another box easily.

� 7) What about security? � RACF is installed, but with minimal configuration.

� The sample configuration guide has suggestions for basic security.

� Security is a site choice. The ability to customize z/OS on a platform designed for individuals or small teams may:

– Provide better testing opportunities

– Provide customization for individual productivity gains

– Provide opportunities to learn about z/OS fundamentals


RD&T host machine specifications

� Underlying Linux host

�Red Hat Enterprise Linux 5.3 (RHEL 5.3)

�OpenSUSE 10.3, 11.0, and 11.1� Note: IBM does not support installation on other distributions.

� Base machine must have:

�at least 3 GB of real memory:

� 1 GB is required for the 64-bit Red Hat or openSUSE Linux

� 1-2 GB is required for the System z operating system, depending on the size of the development system

�at least 80 GB free disk space available after Linux� Note: RDz UT has been tested on:

� Lenovo ThinkPad W Series

� IBM System x 3500 M1, 3500 M2, 3650 M1, and 3650 M2

RD&T Usage Scenarios – Common threads

� Where do builds take place?� Compilations can be done in RD&T or the mainframe� Production builds should always take place on mainframe

� Where does source code reside?� This is a major design point.� Moving data can be manual, semi-automated or fully distributed.

� How does one move source or data from/to RD&T?� Move data from/to RD&T much like you would to an LPAR� RDz drag and drop, FTP, sftp, XMIT, NFS, DFS, etc

� Non-VSAM files need format conversion before & after transfer

� RD&T provides facilities for transferring whole disks to RD&T


RD&T Usage Scenarios Examples

Scenario Source Location

Build Location

Description

Mainframe Build Mainframe Only Mainframe Outputs copied to RD&T. All source updates made on host.

RD&T Build Mainframeand RD&T

RD&T Source copied to and changed on RD&T for local development. Source must be returned to host SCM.

Distributed Build Mainframeand RD&T and possibly elsewhere

Determined by SCM.

Example: RTCz build agents

SCM takes care of source and build locations. Build requests are serviced on RD&T, host or third party build machine. Outputs are made available to RD&T for testing.

This scenario automates the processes of the other two and is least prone to source code synchronization issues.


39

Summary - Benefits of the RD&T Feature• Increased application quality using the included IBM runtimes for testing. Provides a high fidelity testing

environment.� Functionality and services more accurately reflect the mainframe�Using actual z/OS middleware means less retesting and rework is required when moving from the unit test

environment to the quality assurance or pre-production environment.�Developers have an isolated test environment to test application changes that can then be easily merged into the next

level of testing

• Deployment of the Unit Test feature on a PC lowers development and unit tests costs and allows MIPS to be reallocated for production use.

• Executes on an x86 Server

• Utilizing zero development MIPS on the production mainframe for initial application change testing

• Frees up additional capacity for new workload while reducing line of business development costs and chargeback.

• Provides developers in a single or shared user configuration with increased flexibility and control of the test environment, allowing them to be more productive and improving application delivery times.

�Can be assigned to a single developer in a laptop configuration, or can support small-scale team environments �Environments can be tailored to a single developer or team's runtime needs without altering mainframe testing

environments. �Can provide a greater level of control for developers to implement quick environment changes without having to

involve production operations staff. �Developers can perform their first series of tests and regression testing without worrying about causing unexpected

errors.


40

Summary� RDz is an Eclipse-based IDE speeding mainframe

program maintenance and modern composite (SOA) application development

� A complete, integrated J2EE or EGL development environment allows development of complete composite applications from a single development environment

� RDz offers Source Code Management integration tools to access both mainframe and distributed code repositories

� RDz includes runtime specific tools, such as CICS explorer, for working more productively with the traditional System z runtimes

� Traditional mainframe programs can be developed or maintained using productivity increasing tools

� zOS runtime web services can be easily developed, tested, and deployed from the workstation

� Integration with other IBM and third-party tools offers a more complete development experience
