IBM Rational Performance Tester (RPT) is a tool for automated performance testing of web and server based applications.
It allows users to create tests that mimic user transactions between an application client and server.
RPT captures data at the protocol level and supports applications based on the below protocols:
During test execution, these transactions are replicated in parallel to simulate a large transaction load on the server. Server response time measurements are collected to identify the presence and cause of any potential application bottlenecks.
RPT test playback does not invoke the client of the application you are testing. RPT does load testing only on the server (no testing is done against the client).

What is an IP alias
IP aliasing is associating more than one IP address to a network interface.
IP aliasing in RPT
By default, when you run a schedule, each virtual user has the same IP address. However, you can make each virtual user appear as though it is running on its own host. To do this, you configure IP aliases on the host computer (RPT workbench), and enable IP aliasing in the schedule. When you run the schedule, the network traffic will appear to be generated by multiple hosts.
To avoid IP conflicts, the IPs have to be legitimate, available within the same subnet, and blocked for distribution.
Configuring IP aliases for a remote Windows location
To make it appear that a virtual user has its own IP address during a schedule run, configure IP aliases for each Windows remote location.
Now, when you run the schedule, it will give the impression that the network traffic is being generated from multiple hosts.
Note: To add multiple IP aliases, use the netsh command, as shown in the following example:
The ntcmds.chm file, typically located in C:\WINDOWS\Help, contains more details about the netsh command. When you are finished with the IP aliases, use the following command to remove them:
You can also use a batch file to add and delete the aliases.
Enabling virtual users to use IP aliases
After you have configured aliases at on remote computers, you set the schedule so that the virtual users can use the configured IP aliases.
To set the schedule so that the virtual users will use the IP aliases during a run:
Assignment of IP addresses for each virtual user in RPT
When IP aliases is enabled, it is expected that each virtual users have unique IP address available in order to emulate unique virtual users. However in some circumstances the number of IP address available may be less than the number of virtual users.
The answer to this is, when the location has IP aliasing enabled, RPT will ask the agent computer how many IP addresses it has available. It is up to you to have already configured the computer with these IP addresses. By default, RPT will use all IPv4 (but not IPv6) address available. You can also restrict the selection to IP addresses on particular interfaces.
If there are more virtual users on the location than there are IP addresses (which would normally be the case), RPT will distribute the virtual users evenly (more or less) across the available IP addresses. For example, if your location has IP addresses 192.22.22.02, 192.22.22.03, and 192.22.22.04 and you ran 10 users on the location, you would have a distribution similar to:
192.22.22.02: Users 1, 4, 7, 10
192.22.22.03: Users 2, 5, 8
192.22.22.04: Users 3, 6, 9
Identifying the originating IP address for each Virtual Tester
By default, when you run multiple Virtual Testers the originating IP address will be the IP address of the system hosting the individual Virtual Tester. However, RPT does have a feature (IP Aliasing) that allows you to assign a specific set of IP addresses per Virtual Tester (See the topic ‘Emulating network traffic from multiple hosts’ in RPT online help). If you have IP aliasing set up, there are two ways to verify the originating IP address.
You can see the IP address that a virtual Tester is using by setting the Test Log level of your schedule to ‘All’ and then checking the Extended Properties of a request in the Test Log after a playback. The originating address of the virtual user will appear as the "Local IP Address".
Alternatively, there is a custom code class outlined in the RPT online help (Extending Rational Performance Tester Functionality -> Custom Code Examples -> Retrieving the IP address of a Virtual user) that you can add to your test/schedule that will obtain the IP address

Why do I blog about Rational License server, RPT, RFT, CLM, anyway? Why do I even recommend it? Who will gain anything out of it?
If you ask me I will have loads to say as I love blog posts, especially those that can take you through the entire process of troubleshooting, installing a software, or building an application from A to Z. After reading many technical blog posts from different authors and writing many myself, I’ve decided that it’s time to share a workflow that I hope will help those who are creating amazing things to blog more easily and often.
Writing blog posts isn’t easy. Most technical posts require lots of thinking, putting together reporting, scripts, testing, scratching your head when they don’t work right, trying again and again till you succeed. There’s the time it takes to upload images, to get them aligned properly into posts, to get everything just right.
But writing regularly about Rational Licensing concepts has become a very valuable part of my learning process, which helps me connect to my clients and help them grow without any technical hiccups..
Lets understand what one can do to enhance technical blogging: How to write a technical blog
Upon reading couple of books/articles on blogs, this is what I think will best fits in:
Research Deeper into the Topic, I like to include this step after the brainstorm, so I don’t pollute the creative process with external ideas.
Now that you have some of your own original ideas out on paper, it’s time to find out what knowledge has been already uncovered. I suggest that you
a) timebox this step and
b) use resources beyond simple Google searches.
Think before you act : Understand that what kind of blog are you going to write [ A Plan for Your Blog ]
Let Your Personality Show
Blogs began as an intensely personal medium, often having a diary-like quality to them. While blogs have since evolved, many still convey plenty of personality. "Let your personality show," "Remember to be yourself."
Unless you feel strongly about your subject, you will have a tough time succeeding as a blogger. "You have to enjoy what you are blogging about -- it's as simple as that, "If you don't, it will feel forced and your readers will notice."
Explain Technical Matters
No matter what your profession, you likely have to explain complicated topics to people who don't understand. Maybe you're a scientist trying to explain DNA to your grandmother, a literature professor explaining metafiction to drinking buddy, or an IT professional explaining reporting tool to your significant other. Regardless of what you're explaining, you can make it easier on yourself (and the person trying to learn).
Blogging requires time -- lots of time. "The number one thing is to blog as often as possible and to make every post as interesting and useful as possible.
Reference Other Bloggers
Be sure to link to influential bloggers and their posts within your own blog; if you're lucky, they will link back. But don't focus solely on the top one or two bloggers, or else you will look like you just want attention (and links). Other bloggers with clout who aren't the stars of the scene may be more likely to link back to you.
Promoting Your Blog
Understanding Traffic Statistics and analysis
Building a Community Around Your Blog
Scaling Your Blogging Activities
Beyond Blogging: Your Strategy for Social Media
Determine your motivation for writing a technology blog. This will play an important role in determining which topics you write about and how much depth and background or supporting information you provide.
If you're blogging as a hobby and want to share information you know as well as technical information you're learning regularly yourself, you can choose diverse topics that interest you at a specific time.
Can you write about something if you’re not an expert on it? YES you can!!
Try to just write about your findings and research, document your work so far, link to your references, and write down your questions. People may help answer your questions, or you may answer them yourself in further posts. You’ll learn a lot just by writing a careful, thoughtful blog post about what you’re doing.
Write Smartly, but don’t try to sound smart!!
Writing a technical blog helps make you less isolated. It gives the community a chance to get to know you in ways they wouldn’t otherwise. Even if people don’t subscribe and read every post, if you blog regularly and tweet a bit about it, people will find you and get a sense of who you are.

In Rational Test RealTime (RTRT) I want to test function foo() in the sample source code, where I will expect stub call some_Task(), but some_Task() function is present in endless loop.
To handle this endless loop, in order to do that I need to foreclose exit through RTRT from function foo().
I can use setjmp()/longjmp functionality to "exit" a test under certain condition. If some_Task() is stubbed then it can be done.
The below steps explain how to resume the execution of the test script when user code has reached an handled exception:
- stub the function that would put the user program in 'stopped' mode or 'exit'
- resume the execution of the test (using setjmp/longjmp combination)
First of all, the ptu has to include the header file <setjmp.h>
Note the use of '@' that would prevent the PTU parser to search for this file.
At this stage, the compiler header files might not be available.
Then, the setjmp structure has to be declared:
DEFINE STUB PTU_globalvar
Then, a user function has to be stubbed :
DEFINE STUB STUB_c
Then, in the test code include :
@if( ! setjmp( failure_setjump) )
This should help in forming a test case to handle the endless loops.

Integrations between Rational Team Concert and Rational ClearQuest
There are various types of integration capabilities between IBM Rational Team Concert (RTC) and Rational ClearQuest: the bridge, the synchronizer, and the importer. If you are looking for help in deciding which integration capability best suits your current deployment or your future deployment plan, read on to get a better understanding about the technologies that are available to you, as well as some of the deployment considerations.
Note: Additional "Getting Started" information and "Quick Tour" videos are available in the Rati
Rational ClearQuest Bridge
The Rational ClearQuest Bridge provides a bi-directional traceability link from records in Rational ClearQuest to work items in Rational Team Concert. It is a linked-data type integration based on the Open Services for Life-cycle Collaboration (OSLC). It provides a seamless user experience with rich hover UI preview, and delegated dialogs including advanced selection dialogs, and fully functional creation dialogs. These dialogs support ClearsQuest record form layout and hooks. The bridge integration also enables ClearQuest live data on a Rational Team Concert dashboard.
Rational ClearQuest Bridge is primarily for users who want to continue to use Rational ClearQuest as a change management system, but also want to take advantage of other features of Rational Team Concert, such as agile planning and dashboards. You do not have to change your current usage of Rational ClearQuest, but you can enhance your Rational ClearQuest deployment by using Rational Team Concert in a complementary fashion. It provides a ClearQuest shop with a fast path to realize the value of Rational Team Concert.
It is implemented as a function of the ClearQuest Web and uses the ClearQuest OSCL REST API interface. ClearQuest is an OSLC Change Management(CM) provider and a consumer. It provides OSLC CM v1 and v2 interfaces, and also consumes OSLC CM services provided by other tools. ClearQuest OSCL REST API is also a desired interface if you want to integrate your own application to ClearQuest. Since it is HTTP-based, you can call it from any program that supports HTTP, and it does not require the ClearQuest client to be installed on the machine where you execute your application.
Through the same bridge integration technology, you can also integrate ClearQuest with other Rational tools, such as Rational Quality Manager (RQM), Rational Requirement Composer (RRC), and Rational DOORS, and with 3rd party tools, such as HPALM and Git.
Rational ClearQuest Synchronizer
The Rational ClearQuest Synchronizer is a data replication between Rational ClearQuest records and Rational Team Concert work items. It supports flexible bi-directional or one-directional synchronization between a Rational ClearQuest record and a Rational Team Concert work item. Changes in one application are applied to another using synchronization rules, which provide the mapping and transformation information.
It is primarily for the customers that want to incrementally adopt Rational Team Concert by having different teams use different tools. Some projects/teams (for instance, a development team) can choose to start using Rational Team Concert while other teams (for instance, a support team) continue to use ClearQuest. The teams using Rational Team Concert and the teams using ClearQuest have access to the same data (duplicated by the Synchronizer based on the configured sync rules). Reports can also be run in either system since the data is consolidated.
The ClearQuest Synchronizer is implemented as an application of the general Jazz item connector framework. It is a separate component of the Rational Team Concert offering, and requires setting up a Gateway service. It uses ClearQuest CM API interface to communicate with ClearQuest. It can also be used between Rational Qualify Manager (RQM) and ClearQuest.
Please note that there is a high maintenance and support cost associated with the Rational ClearQuest Synchronizer. Conflicts can occur when two users make nearly simultaneous changes to a ClearQuest record and its corresponding work item, and an administrator needs to constantly monitor these conflicts and resolve them manually by selecting the appropriate value. It is highly recommend that you evaluate the Rational ClearQuest Bridge integration before jumping into the Synchronizer integration.
Rational ClearQuest Importer
The Rational ClearQuest Importer provides a one-way data migration from Rational ClearQuest records to Rational Team Concert work items. It imports ClearQuest records based on a user specified query, and uses a mapping file to declare how fields and values are mapped from a ClearQuest scheme to a Rational Team Concert process definition. It supports importing stateful record types, Users, Notes, Attachments, Work Item Relationships (duplicates, parent / child, blocks / depends on, and related), and creates missing objects, such as Contributors, categories, and iteration, on the fly.
The Rational ClearQuest Importer is primarily for the customers that want to move from using ClearQuest to Rational Team Concert as the change management system instead of maintaining both applications, and want to bring over certain ClearQuest records to Rational Team Concert.
It is implemented as a function in the Rational Team Concert eclipse client. It is based on the Bugzilla Importer, and uses the ClearQuest CM API to communicate to ClearQuest. You must install ClearQuest client on the machine you run the ClearQuest Importer.

While working with Rational Functional Tester (RFT) on Firefox browsers, if enablement test failures are observed, then I follow the below steps to resolve them. These can be checked to avoid enablement issues.
1 Launch RFT as Administrator.
2 Make sure same version of JRE is enabled in RFT and the Firefox browser.
Refer the links on how to enable JRE and browser in RFT http
3 Launch the Java Control Panel from Control panel and verify the Java version
4 The version should be the same which is enabled in RFT and browser . If that is not the case, then Add the correct version and enable it.
5 If Security Level under Security Tab is set to Very High or High , then set to Medium or low
6 Under the Advanced tab, make sure the settings are as below:
Console can be hidden later , but enabling it will help to ensure that correct version of JRE is associated with the browser (remember that there could be multiple JRE associated with the browser). Disable next-Generation Plug-in unless it is compulsory.

We'll be back tomorrow with more great content focused on helping you get the most out of IBM Rational Support and your IBM Rational products!
For now.... It is that time of year when many Americans roll out that one last big blow-out barbecue party before the summer comes to a close and we look toward welcoming winter, albeit a bit trepidatiously. While the holiday has indeed come to symbolize the end of summer for many of us (it isn't, summer doesn't end until September 22), it started and remains as an American federal holiday to honor the worker; a day when we recognize the contributions of the American worker by relaxing and eating lots of BBQ
All this, of course, means your loyal blog admins are off gallivanting (or just sitting on the sofa) and not actively working today. But that doesn't mean we don't have some good content for you! In this case, it is a video from IBM Electronic Support guiding us all on how to download software from the Fix Central repositories.
Archived 'Filed Against' values are available in the drop down of Filed Against column in a plan view
