Information regarding potential future products is intended to outline our general product direction and it should not be relied on in making a purchasing decision. The information mentioned regarding potential future products is not a commitment, promise, or legal obligation to deliver any material, code or functionality. Information about potential future products may not be incorporated into any contract. The development, release, and timing of any future features or functionality described for our products remains at our sole discretion. Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

RD&T host machine specifications Underlying Linux host Red Hat Enterprise Linux 6.X OpenSUSE 11.2 Note: IBM does not support installation on other distributions.

29 RD&T host machine specifications Underlying Linux host Red Hat Enterprise Linux 6.X OpenSUSE 11.2 Note: IBM does not support installation on other distributions. Base machine must have: 64 bit Intel compatible processors with one core per allocated z/os CP plus one core for native Linux. Up to 3 z/os CPs and one native Linux are supported per instance of Rational Development and Test Environment for System z 2-4 GB of memory per z/os CP, plus 1 GB for native Linux GB of disk space for z/os At least one Ethernet adapter is required for OSA operation Rational Development and Test Environment for System z USB hardware device Note: RD&T has been tested on: Lenovo ThinkPad W Series

30 Common Questions 1. What is the maximum number of developers a RD&T server can support? This can vary depending on the underlying hardware and development activity. Desktops can typically support 3-5 users. Server class machines can support up to users. 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 DASD volume migration utility that can download an entire 3390 DASD volume onto the RD&T machine. 3. Can I run other levels of the middleware provided? RD&T is supplied with a standard set of software middleware, compilers, and runtimes. The included license covers this software at the supplied versions. Special license terms and conditions for other versions/ releases of software may be created as long as the requested software is currently in service and remains in service 6 months form the sales date. 4. Can I use other IBM tools in the RD&T environment? ESW zotc or zmlc tools (like PD tools) currently are not licensed for use with RD&T. Passport Advantage products can be used in the RD&T environment. Exceptions to these rules are handled on a case by case basis with individual IBM product owners. 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.

31 Additional Questions 6. Does RD&T require linux skills? Linux skills are required to setup the host linux operating system and to allocate linux resources for the System z architecture simulator Some linux networking skills are helpful Linux program installation and maintenance skills are also required 7. Does RD&T require system programming skills? z/os does require system programming skills to set up the development and/or testing environments. IBM recommends setting up one box and then cloning that configuration to other boxes. 8. 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
