Back in Mid February, IBM eSupport launched a new IBM Electronic Support Site as a great starting point. You can use this page as a fabulous jumping off point to find all the great eSupport tools available to you, organized by task. And don't miss some of the best features: embedded social streams and videos covering helpful topics and how-tos related to electronic support.
Yes, we've been doing this all for a bit now, but we'd still love to hear your feedback about how we're doing, and what improvements you may like! Our short nine question survey will only be available for a few more days (until June 22nd). The survey shouldn't take more than 5-10 minutes of time to complete. This is a chance for you to help drive the future of Rational Support's social media initiatives; to have a voice about what changes we could make to help YOU realize even more benefit from our social media channels! Of course we are always open to comments here and in our other channels as well
As you likely have read previously, we launched the Notes from Rational Support developerWorks blog in January of last year, our Twitter @RationalSupport presence in April, Facebook in November, and YouTube in December, with no other agenda than to share knowledge with you, to help you be successful with Rational products. Through these channels we share new and popular technotes, download documents, IBM Education Assistant modules, information regarding our electronic support tools and programs, pertinent developerWorks and jazz.net articles, how-to videos, webcast/open mic invites, and even interviews with some of the many interesting people that make up our Rational Client Support teams. And we'd love your feedback on how we are doing when it comes to providing you with the information you need and want!
So hurry, the survey will be closing soon! If you haven't yet, you can still enter your responses here: http://ow.ly/1R9G7

Now that 'ToB' is complete, the process of loading Ounce Labs client entitlement data into IBM systems is underway. Once complete later this month, Ounce Labs clients will be able to access IBM Software Support for product assistance as well as download software and licenses using IBM tools.
For up to date information related to the Support transition, please refer to (and bookmark!) the following Ounce Labs Support Overview page:

After the wizardry of my previous post, where you learned how to install the Rational License Key Server Administration and Reporting Tool by using the IBM Installation Manager wizards, let’s now slay some demons! In this post, I will help you understand how a typical licensing model works and how, specifically, the Rational licensing model is designed, complete with daemons!
A licensing model generally consists of:
The license file defines what software or features the license is for, how long it is valid for, how many users can use the software, the computers on which the software can be used, and so on. The license file can be stored locally on the same computer as the application, or on a remote license server. In a served license model, where licenses are stored and served from a common license server, the applications that require a license connect over a TCP/IP network to obtain the licenses from the license server. Rational Common Licensing supports both options local license file deployment and the served license model.
The Rational Common Licensing model consists of the following components:
When you purchase an IBM Rational product, you receive a license entitlement that authorizes you to generate and download license files from the Rational License Key Center. The Rational License Key Center is an online service that you use to create license files (.dat, .upd, .txt) for the application or applications that you have purchased, or in IBM parlance, “have entitlement for”. As I mentioned earlier, the license file:
Tip: Do not change the host name when you migrate your license server from one computer to another. If you do change the host name, be sure to log into the Rational License Key Center, return your existing license and regenerate licenses for the new host computer.
For single desktop applications, you can store the licenses on the same computer as the application. You also have the option to run multiple instances of the application on the licensed computer. For applications that are used on several computers by different users, you can use a served license model. The licenses are held centrally by the Rational License Key Server and served up to requesting applications and users.
Let’s take the help of an illustration to clarify the concept of a served licensing model.
Fig 1: Rational Common Licensing process
Log in to the Rational License Key Center to generate and download your licenses. After you download the license files from the Rational License Key Center, you can use the Rational License Key Administrator (LKAD) to import and deploy the license files to the license server. Depending on your product type, you will need to use different mechanisms to point to the license server:
See the daemons in the illustration? Those two daemons - the lmgrd manager daemon and the ibmratl or telelogic vendor deamon - manage licenses on the license server. The lmgrd daemon runs on the license server. The vendor daemon information is supplied for each application in the license file for the application. The lmgrd deamon handles the initial contact with the client application or the IBM Rational product. It reads the license file, identifies and starts the appropriate vendor daemon, and then passes on the connection to the vendor daemon. The vendor daemon tracks how many licenses are checked out and who has the licenses. An application that requires a license connects to the license server and requests a license. The license server provides a license based on the availability of the license. The daemons write information about license usage to the lmgrd.log file. The License Key Server Administration and Reporting Tool uses the information in this log file to generate reports on license usage.
That, in a nutshell, is an overview of the Rational Common Licensing model. In my next post, I will pick up from where I ended here, and describe how the License Server Administration and Reporting Tool uses the log data and works with the license servers to generate reports.
