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.
IBM Software Group | Rational software
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.
IBM Software Group | Rational software
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

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

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
IBM Software Group | Rational software
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
Mainframe
and RD&T
RD&T
Source copied to and changed on RD&T for local
development. Source must be returned to host
SCM.
Distributed Build
Mainframe
and RD&T
and possibly
elsewhere
Determined by
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.
Example:
RTCz build
agents
This scenario automates the processes of the
other two and is least prone to source code
synchronization issues.
IBM Software Group | Rational software
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.
