DevOps is reshaping the future of ALM as noted in a recently published Forrester report, Continuous Delivery is Reshaping the Future of ALM, saying "DevOps is now noisily elbowing its way into the mainstream- the revolution is just beginning, but it’s real and the time to act is now."
IBM DevOps is an essential enterprise capability for continuous delivery that enables organizations to seize market opportunities and reduce time to customer feedback. DevOps enables organizations to adopt and continuously improve in lean and agile practices through shared learning, while extending the boundaries of agile to encompass the full business/client value stream. Effective ALM is a key practice that helps organizations implement a DevOps approach because it allows them to efficiently deliver applications and services with robust performance, transactional integrity, security and control.
We ask that you continue to participate and contribute your ALM expertise to the DevOps Community moving forward. Join our new DevOps Communityto post questions to the Forum or get community insights from our Blog. We look forward to exchanging ideas with you.

Are you curious to know what actions take place internally during the "Performing Test Log Data Transfer" stage in Rational Performance Tester (RPT)?
Here's some background on what happens during the "Performing Test Log data transfer" state:
STAGE-1) During the test, stub files will be created in a temporary directory in a system's temporary location on the RPT workbench system. This directory will have a name like rpt.<ScheduleName>.<number>.
For example: If you have agents named Agent1 and Agent2, the stub files will have names like:
As the playback is running, the actual traffic is written to corresponding files on the agent machines under the agent's deployment_root directory.
STAGE-2) When the playback reaches the "Performing Test Log data transfer" state, RPT will first move the files from the agents to the same temporary directory (rpt.<ScheduleName>.<number>), replacing the stub
files. This is done serially for each agent (i.e. files are moved from Agent1, and then from Agent2, ...). During this step, ideally the ACWinService.exe on the agent currently transferring files will show CPU
use of 5 - 15 %.
STAGE - 3) Once the files are retrieved from all the agents to the temporary directory, the files from all the agents are combined into two files with names like DLRDirectoryAreaPagingFile<number>.dat and DLRPagingFile<number>.dat in the system's temporary location.
STAGE - 4) After the two above files are completed, the rpt.<ScheduleName>.<number> directory is removed.
STAGE - 5) Finally the data is combined into the .executiondlr file in the project. You may check with the files and find out in which stage RPT is completing.
From a product perspective, whenever you encounter a peculiar error or behavior it becomes difficult to think of a starting point that could help you drive towards understanding the cause. Such scenarios demand more information and to have a keen look into the log files generated by the respective application. Such logs as meant to accumulate the granular information based on the configuration or settings imposed while working on a asset under test.
In-line to this from troubleshooting point of view, the initial gathering of data such as logs, product versions and system data plays an important role in investigating the problem reported. A new step towards designing a data collection executable which will help you to retrieve the following information and provide it to IBM support for investigation was put into practice successfully when we released the Data Log Collection Utility last week.
Following are a few data points that this .exe file gathers:
Vital Rational Performance Tester logs
Information about the Product Version installed.
Platform System Environment Details
The intention of designing this utility is that it would help avoiding the initial 3 - 4 interactions required by the Technical Support Engineer to collect basic system and log information. Thus reducing the resolution time cycle of the Problem Management Record.
For more information on how to execute this data collection utility, you may refer the following link:
Check out this new CLM whitepaper from Rational Client Support's AVP team member Dayal Sachdev!
Dayal knows that clients today face challenges scaling Jazz environments appropriately and maintaining them, and has written this whitepaper that describes one approach to monitoring a server layer and captures those results for analysis using Resource Monitoring with IBM Rational Performance Tester. The target audience is administrators whom are in charge of hosting and maintaining Jazz CLM tools today while having a moderate understanding of load testing concepts and Jazz tools.
This is an introduction to the Rational Client Connect program from the Rational Support team. This program helps you get started with electronic support activities such as downloading software, obtaining licenses keys, finding content, and submitting service requests to support.
One of the IBM Rational Team Concert (RTC) users, having an integration with Focal Point (FP) were planning to move the production database
to test. On refreshing the test database, as they had RTC-FP integration in production, the same links would be preserved in the artifacts in test.
They had a concern if these links will be preserved in RTC, even in the test area after refresh. Of course, they would edit the Friends connection,
to point to the Test.
Here are the steps that I suggested and one of which was successfully used by the customer to isolate production from test (step 2).
The RTC links will be preserved in the Test area after refresh.
If the plan is to have a Test environment without the RTC links (in test database) to point to the production data, there are 2 options one can choose from.
Isolate the production and the test environment at network level.
Below are the details of each of these options:
1. Server Rename
Server rename is one of the approaches to achieve this. However, this has it's drawbacks and risks, explained in the links below:
This should definitely be the last approach one can take, after raising a Problem Management Record (PMR) with IBM Rational Support.
a. Server rename and the things to be aware before proceeding:
NOTE: One needs to make sure that there are no possibilities of communication exchange between the test and production servers at all.
a. First, ensure that production and test servers are isolated at the network level so that any communication attempt is blocked.
This is to make sure the Test environment should not insert or update anything on the production environment.
b. Install CLM applications, Websphere Application Server (WAS), database on the test server following the usual methods.
c. Restore the copy of production databases in the test server.
d. Ensure the password of the database user (which is used in the CLM applications to connect to the database) is different than in
production. This can be the DB instance user, if one has used so.
Now, one needs to tell the server on how to connect to the new databases (the ones which were restored in Test environment), where the password
To get the encrypted password:
f. Run the jts/setup till Step 3 - Configure Database and
look at the jts/teamserver.properties file (which should now be in the process of getting regenerated) for the encrypted password.
Copy it in a word editor. The property name to look for the password is
g. Copy over the entire .../server/config directory from the production server to the Test server and open each of the teamserver.properties
file and update the password as noted in the above step.
i. Create an entry for production server in /etc/hosts file of test server.
Start the application in WebSphere and test.
NOTE: It is best to test this when production environment is offline or down for maintenance to avoid any unforeseen problems.
At this stage, the Test environment can only be accessed from test server and not from any clients, as the DNS is unaware of the alias in
To access the Test Environment, users can put a similar entry in their respective machines /etc/hosts file to point it to the Test environment.
The IBM Rational Client Success Team is holding an Open Mic session covering access to the Rational product Help content.

IBM Rational Rhapsody family provides a collaborative design, development and test environment for systems engineers and software engineers. It uses Systems Modeling Language (SysML) and Unified Modeling Language (UML) to enable rapid requirements analysis and visual, model-based design.
The UML diagrams are views into the underlying semantic system model; each kind of diagram emphasizes some aspect of the model.
Example - Dynamic aspects is represented by behavior diagram - State chart.
Statecharts define the behavior of objects by specifying how they react to events or operations. The reaction can be to perform a transition between states and possibly to execute some actions. When running in animation mode, IBM Rational Rhapsody highlights the transitions between states.
The discussion covers few modeling challenges with state chart using Rational Rhapsody and how to over come those challenges:
1) Evaluation of condition connector in state chart
A scenario where a variable (count) is decremented before the condition connector and is expected to terminate if value of variable is 9 (count==9).
However, on executing you observe that the condition doesn’t take the change in the variable on the transition. Instead it takes the initial value of the variable for comparison.
The work around here is to have an additional dummy state in between to get the desired output.
2) Multicasting with rapid ports in layered structure
Currently, the multicasts of event via rapid ports (ports that have no provided/required interfaces) are supported only from a direct invocation.
Example - One sender object and two receiver objects
Consider a scenario where the event is first sent from the Class A's object(itsA) and then it reaches the Class B's object(itsB), from where it is delegated to its 2 inner parts(itsB1 and itsB2
No multicasting is available on having multi layered structure.
The Workaround is to add an additional state chart and MULITCAST_GEN() macro in class B.
3) Working of Reaction in State
In a single state for a Reactive class, you would expect to continuously print a statement after elapse time of tm (1000). However, upon execution it prints only once instead of continuous timer.
Using a tm (1000) as a trigger for a reaction in state means that 1 second after you enter the state you'll be triggered. It's not a continuous timer.
To restart the timer you have to exit the state and re-enter it. It needs a design change as below.
4) Combining Junction Connector and Condition Connector in a state chart
You would like to have several events from a state and a condition to determine the other state.
You cannot join several transitions into a condition connector neither you can have a transition from a junction connector to a condition connector.
However, you can model to add a dummy state in between that will further evaluate for condition connector.

September has come and gone, but the important data remains! These are the top 15 technotes for Rational Team Concert that were reused during September to help solve your PMRs. Last month the following technotes were the most heavily reused when closing PMRs opened by you, our clients. We hope that highlighting them here will help others encountering the same or similar issues also find quick resolution:
Here is an example requirement that one of my clients was looking for in IBM Rational Team Concert who asked: "Is it possible to select an enumeration value for an attribute and this in-turn based on the value selected, display text area in RTC?"
There is an attribute named 'Location' and the enumeration values for this attribute are 'USA, UK, India'. Now if the users select any of these enumeration values, say 'USA', they should get a field next to this selected enumeration value displaying a text, say 'Miami' or so a field where users can write the location manually.
Is this feature available in RTC 4.0.1, 4.0.2 or 4.0.3? At the time of writing this article, there is no straight forward way to achieve this requirement for the RTC versions mentioned.
--> This requirement can essentially be broken into 2 sub-requirements:
Attributes with values dependant on another value.
Here is a jazz.net article which should help one in customizing the requirement:
'Read-only control for Work Item attributes in Rational Team Concert 4.0' https://jazz.net/library/article/997/
--> However, there are a few RFE's which are in discussion for CLM 4.0.x, as mentioned below:

There have been few queries from clients asking if it is possible to import work items by e-mail into IBM Rational Team Concert. This is a somewhat complex topic as it isn't currently supported, but there is a potential work around. Let's take a look at the information:
A. There are the following properties in Advanced Properties page of the CCM application in RTC:
Online Help for this says: "A periodic task runs on the server that checks for mail received for work item creation. This property specifies the time in seconds between runs of this task."
B. Here is a brief on this feature from Jazz.net wiki:https://jazz.net/wiki/bin/view/Main/WorkItemEmailImport
However, as the link says, it's still in experimental stage and not supported, at least as of the RTC 4.0.3 version. This should perhaps be implemented in one of the future releases.
