I'm working on.........
I am Guru Prasad, working
for Tata Consultancy Services. I am working as Rational Product Specialist
& part of TCS Rational CoE team. I have conducted several internal
webinars, workshops on various Rational tools including Rational Software
Architect, Rational Requirement Composer, Rational Requisite Pro etc. I always
like to develop custom extensions for Rational tools. I
keep myself skilled & updated on rational trends I always focus on Self educating myself on
IBM Rational tools. Most of the time I spend browsing IBM Jazz.net, IBM
Developer Works & go through the latest releases of the tools, discussion
forums, articles on Rational tools. Also, I attend most of the webinars
conducted by IBM Rational User Group. I do write Rational articles & publish
them in the internal sites. I also assist my team on POC activities / publishing
white papers on Rational in External forums like IBM Developerworks, jazz.net
Since most of the Rational tools
are Eclipse based, Rational users can develop custom extensions easily using the
Eclipse Plugin development features. IBM provides REST APIs , Java APIs to
extend features of Jazz based tools. Users can connect to jazz.net, RUG forum
& discuss on the queries specific to such implementation. My accomplishments I am an active member of IBM Rational User
Group & IBM Certified Deployment Professional & Solution Designer. I
have developed several plugins for Rational tools on demand.
Below are the methodologies which have been proven to be highly successful in RFT automation projects
Steps in designing the architecture First Step: Organize the code into a layered architecture as per the ITCL architecture
1. First Tier : AppObjects -->All the application objects of the application reside in the AppObject scripts. All the finders will be in this package/script 2. Second Tier : Tasks --> Methods around these Appobjects to do a task eg: Logging into an application 3. Third Tier: Test Cases --> The scripts which actually verify and test the application. Testcases are abstracted from the Appobjects which make this architecture robust
Here, the test cases talk to tasks and tasks in turn talk to Appobjects
Advantages of this architecture 1. Highly Organized code 2. Ease in debugging 3. If an application object changes, tester need not update all the test scripts having the appobject, but he needs only to modify the affected appobject and all the test cases are automatically updated. This is due to the fact that the test cases are abstracted from Appobjects
Second Step: For Web/Dojo Applications Using BLUE and below hacks
If the application is a Dojo application, we can further use BLUE framework on the top of ITCL. BLUE contains very robust methods for Dojo.
Also, for Web applications, if the RFT tool does not recognize the objects beneath the layers/pages, we can further use the IE developer tools to find the unique properties of the object and feed them to the RFT tool dynamic find
One can make the code browser independent by making the document page as the top parent instead of making browser as the top parent. All the underlying code will be having the document page as the top parent.
Third Step: Scripted Verifications
Use scripted verifications instead on recorded verification to verify the state of an application. it makes the automation suite very robust and resilient to the application changes For instance a verify_table method will fetch the contents of a table/grid during the first run and write it in an excel and place it in an expected results cannon. During the subsequent runs, it will again fetch the contents of a table/grid and write to an actual excel file. The method then compares the two files and logs the result
Fourth Step: Appobject Unit Tests
Keeping the Appobjects Unit Tests in place makes a confident automation code. Once the build is ready, the appobject unit tests are run to ensure all the application objects are recognized. If there is a change in object properties, the tester updates the recognition properties. This will further ease the debugging effort as we are sure the test cases are failing due to a bug/ defect or due to a functionality change and not due to object recognition
Fifth Step: Multi Client Test Script Maintenance
Using a property file can make a single test script to run on multiple clients. This is done by defining a property in the properties file which would instantiate the objects specific to that type of client mentioned.

The most common causes of the errors observed with Rational® Performance Tester, both during Recording & Playback.
Browser and System Port(s)
Cause 1: The browser could already be in use during recording?
Additional Details: RATIONAL® PERFORMANCE TESTER cannot record scripts starting a parallel browser session; this is because RPT needs to create a proxy server port before it can start listening to the traffic exchanged between the client and the server.
Remedy: Close all Browser sessions before attempting a recording.
Cause 2 : Proxy settings in browser might prevent RPT from getting to the browser?
Additional Details: The proxy settings in the browser might be hindering RPT take control of the browser and move ahead with recording.
Remedy: Remove all proxy settings in the browser; also disable the Automatic Configuration scripts if any referred in the proxy settings.
However in scenarios where proxy settings are mandatory, please use the steps as described in the technote
Cause 3: Port 10002 (used by RPT to interact with the in-tool agent controller might be in use) hence
Additional Details: This port is used by Rational® Performance Tester to interact with the Agent Controller (Integrated / Remote) to run load tests
Remedy: Check if 10002 is already in use, if yes, please retry after ensuring that the application using port 10002 has relieved this port. Alternatively, you can try a machine re-start to allow the port to go back to LISTENING mode.
You can use netstat command usage to confirm that 10002 is a free port.
Un-supported network traffic - protocol
Cause: If network traffic used by the application does not fall into the supported protocols category,there might be un-expected behavior.
Rational® Performance Tester includes built-in recorders for the following network protocols: HTTP SAP TCP Socket Citrix Web Services (SOA) Siebel
Remedy: Additional protocols can be built using the IBM Rational® Performance Tester Extensibility Software Development Kit (SDK), here is the link to documentation on this
Best Practices – RATIONAL® PERFORMANCE TESTER Recording
Script Maintenance is a crucial part in effective recording process to ensure that the scripts generated in RATIONAL® PERFORMANCE TESTER are optimal and are in sync with the test plans. Some of the main points to be aware of while recording are:-
Always return to the main screen or page at the end of each scenario or before a log-out. Having common beginning and ending screens is reliable
Apart from the formal change / version control processes, documenting dependencies in the environment which can impact the scripts is a major task which can help avoid deficiencies in the test environment and hence help achieve assigned targets with recording process.
Always document dependencies and other information about your split test modules. This will help with test script maintenance and re usability. Use comments in the test or schedule or by using the properties description field associated with each test
If the details provided above do not help address the concerns, please contact IBM Rational Client Support with the details on the issue.

America's skyscrapers, many built before World War Two, are showing their age. IBM's "building whisperer," Dave Bartlett, believes many of these buildings could use a diet.Bartlett,
who leads IBM's smarter building initiative, is known as the "building
whisperer" because he views buildings as living organisms, an approach
that can help identify problems and suggest cost-effective ways of
making buildings healthier and more energy-efficient. Read more..

After giving training on this tool i think i m very much trained in this tool.
IBM Rational® solutions for collaborative design management enable an organization to bring together a broad set of stakeholders—customers, line-of-business managers, operations, development teams, and others—to contribute to and influence the design of products, software and systems. This new level of collaboration can help to drive improved quality and achieve successful business outcomes.
How effective would it be if we let our customers tell us the features they want in a product we are planning to build, and let them prioritize these features and then we prioritize them against criteria that maximizes customer value and minimizes cost, build those features and make the product available to the market – resulting in maximum return on investment with a product our customers love!
Well, If the above appeals to you Rational Focal Point is your answer. From my experience with Focal Point over the last few years I have realised that this is one scenario which would be an eye catcher for many of us in this industry. I would definitely want to get you to know more about this tool. Let me introduce Focal Point to you more formally - its a unique management tool which automates, improves and supports product management and portfolio management. Be it something relatively simple as to what features would go into the product you build to making a more complex and important decision on which product to build, this tool come in very handy.
Making the right decision is always a challenge. We can make an adhoc and intuitive decision based on previous experiences or a more formal and a calculated one which is based on more critical business issues such as customer priority , market scenario etc.
Let me give you an example:
When we have two alternatives and one criteria, like which of the two between cars A and B is better in terms of mileage, its an easy comparison. But when we include more criteria to the list like which one has better mileage, comfort, speed, looks etc and then make a choice on the best alternative then it becomes a little complex. Imagine a situation where we need to choose between more alternatives (cars) C, D, E and F with increasing criteria set! With Focal Point we solve this situation by doing a pair wise comparison. Compare two alternatives at a time according to one criterion. Then combine all of this and visualize your choices. Sounds easy? You could also have multiple people making their choices based on their priorities and opinions and then get an overall visualization of them.
Now, a few features of Focal Point:
Web Client - A browser is all the end user needs.
Access control through views
A multisite collaboration platform,
Powerful filtering techniques
Built in graphs to enhance visualization.
Easy data transfer(import/export)
Send email notifications on alert situations

The ever increasing challenges of modern day enterprises demand organization to design of effective Enterprise Architecture (EA) for them to succeed and stay alive in the competition. For EA to be effective, it requires collaboration from many professionals, some of them directly designing/modifying the EA and while others are stakeholders who use the EA to make critical strategic decisions. These decisions in turn define the direction of the organization.
To deliver effective EA, many users have to collaborate. It then becomes equally important to have proper "Visibility" to all users to avoid "reinventing of wheel". However at the same time it opens the doors for accidental modifications from inexperienced users creating inconsistency in the system. The after-effects are hard to imagine/foresee and sometimes unexpectedly destructive.
Now in this critical environment where "Visibility" and "Security" form two faces of the same coin, how do you manage effective delivery of EA? While there are many tools which allow creation of EA, IBM Rational System Architect (SA) comes bundled with answers to many more questions than just EA. While Rational System Architect gives you the platform and also forms the tool to design the EA, the Catalog Manager with its "Instance Level" and "Type Level" access Control capabilities complements, completes and addresses the key requirements of "Visibility" and "Security". There is more that catalog manager helps you with. Rational System Architect also offers a thin client known as System Architect XT (Extended Team) which helps sharing EA through browser. For an encyclopedia that contains EA artifacts to be made accessible by Rational System Architect XT, it must be an Enterprise encyclopedia controlled by Rational System Architect Catalog Manager.
