16 RD&T Offering Description RTCz Agent RD&T System z S/W Stack Debug Tool RDz Agent CICS DB2 WebSphere/z IMS Assembler COBOL C/C++ PL/I z/os Unit Test Environment 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 x86 PC running Linux <USB License Key> 31 RD&T limitations 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) 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.

17 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 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

18 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 Software Stack for as-is usage z/os MLC Products IMS V11.1 Database Manager IMS V11.1 Transaction Manager DB2 for z/os V9.1 & DB2 for z/os V10.1 WS MQ Base for z/os V7.0 Enterprise COBOL V4.2 Enterprise PL/I z/os V3.9 CICS TS for z/os V4.1 and CICS TS for z/os V4.2 z/os V1.13 Base z/os V1.13 C/C++ without Debug z/os V1.13 DFSMS dss z/os V1.13 DFSMS rmm z/os V1.13 DFSORT z/os V1.13 RMF z/os V1.13 SDSF z/os V1.13 Security Server z/os V1.13 ISPF Other utilities z/os OTC Products WebSphere for z/os 7.0 DB2 Utilities Suite V9 and V10 WebSphere Portal Enable z/os IBM Debug Tool Other Tools pre-installed RTCz file/build agents RDz RSE and Job Monitor 36

19 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 Distributed Build Mainframe and RD&T Mainframe and RD&T and possibly elsewhere RD&T Determined by SCM. Example: RTCz build agents Source copied to and changed on RD&T for local development. Source must be returned to host SCM. 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.

20 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. 39 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 40
