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.

You are invited to participate in the 2013 Rational VoiCE Jam, a virtual event hosted by the Rational Client Programs team. A jam is a guided online discussion surrounding a set of themes. Participants respond/blog to themes with ideas, ask clarifying questions, comment and vote on the ideas by sharing their like or dislike. By popular demand, this jam will give you the opportunity to share ideas, comments and votes across various products, solutions, and aspects of the Rational portfolio. We have approximately 30 themes that you may follow and actively join in the discussions.

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
C. However, there has been an RFE on this already and you might want to add a comment here with your additional business justification. The details, along with a business justification should add more weight to this RFE.
I hope this note adds to the links above on this topic.

Have you had a chance to check out the new 4.0.4 release of the IBM Rational Collaborative Lifecycle Management (CLM) products (Rational Quality Manager, Rational Requirements Composer, Rational Team Concert)? This new release delivers new features and enhancements such as the following and more:
Asset management, broadly defined, refers to any system that monitors and maintains things of value to an entity or group. It may apply to both tangible assets such as buildings, and to intangible concepts such as intellectual property and goodwill.
Know where your assets are....
IBM Rational Asset Manager is a collaborative environment for creating and governing software assets. A definitive library management system where you catalog, organize, use, reuse, manage, and report on any type of software, technology, or business asset.
A collaborative software development asset management solution, IBM Rational Asset Manager software enables organizations to identify, manage and govern the design, development and consumption of software assets, including services as part of a service-oriented architecture (SOA) initiative. The software helps IT organizations deliver innovative IT solutions while controlling costs, reducing application backlogs and improving business flexibility and responsiveness by facilitating software asset reuse.
Evaluate Rational Asset Manager now! http
Purchasers of IBM Rational Asset manager can choose among three types of product licenses: an Authorized User license, an Authorized User Fixed Term License (FTL) and a Floating license. The best choice for your organization depends upon how many people will use the product, how often they will require access. Lets understand the concepts of keys ( licenses ) behind this dynamic software.
Types of RAM (Rational Asset Manager ) Licenses:
Licensing Model for Standard Edition:
Licensing Model for Enterprise Edition :
Addresses different usage patterns
→ Administrators assign users to AU licenses: Collaborator or Publisher.
→ SE licenses cannot be used in an EE servers.
→ Collaborator license only allows search, download and comment on assets.
→ Audit report can be generated to show license usage.
→ Floating license is consumed by users not assigned an AU license.
→ Collaborator license is consumed initially until a publisher feature is invoked then license consumption switches to publisher.
→ 30 minutes of inactivity or logging out releases the license (Floating).
→ Programmatic access consumes a license → Concurrent programmatic access consumes multiple licenses equal to the number of concurrent programmatic access.
→ When a user searches and browses without authenticating then no floating license is used,
→ When an anonymous user displays a public asset details, then an available collaborator floating license is checked out,
→ When an authenticated user displays an asset, then a collaborator licence is checked out, unless you already have a publisher license from a previous action,
→ When an authenticated user modifies or submits an asset, then a publisher license is checked out ( and if a collaborator license was checked out, then it is check in )
→ When an authenticated user logs out, then the license is returned, for either collaborator or publisher, unless the user had other sessions,
For EE (Enterprise Edition) : each authorized user license is of one access type -> collaborator or Publisher
For SE (Standard Edition) : there is only one license type,
If the authorized user license is of type Collaborator, and the user attempts to modify or submit an asset, then an available Publisher license will be checked out.
Version 7.5 ( RAM ) includes the following enhancements and features:
Server licenses: Rational Asset Manager Enterprise Edition no longer requires the purchase of a server license, providing more flexibility in the deployment of clusters and stand-alone servers
Token licenses: Token licenses are now available. You can reduce deployment costs by sharing Token licenses across one or more Rational products.
