Depending on the complexity of work and projects associated with your organization, complexity of your environment also increases invariably. Your environment might include several tools to assist you in doing your daily job and this may include several products which fall under different category. For example : Change management, Requirements management, modeling tools, testing tools, development tools and so on.
These products may be Rational or Telelogic, Which falls under IBM Umbrella.
You might have to work with both Rational and the Telelogic products and you may very well be the license administrator and your areas of interest may include both Rational and Telelogic product licensing.
Though we have Rational and Telelogic products under the same Umbrella today IBM, there is a difference in the way the licensing works for Rational and Telelogic products.
We will unearth these differences in the working mechanism of the licenses for Rational and Telelogic products and try to understand how they work.
The following section briefs the working of Rational licenses and also throws some light on difference types of licenses available for Rational products
Floating licenses for Rational products are not tied to any version of the product. Floating licenses are always configured on a centralized Rational license key server and the clients are pointed to this license server to pick the licenses.
The scenarios where you are upgrading the client to a different version.
For example: If you are migrating the Rational software architect from version 7.0 to version 8.0 there is no need to update the license file as the floating licenses which you had configured to work with Rational software architect 7.0 will still work with Rational software architect version 8.0 as they are not specific to any version of the product.
But It is always recommended to have a version of the Rational license key server which was released post the release of the product.
Rational products also have authorized user licenses which are tied to a specific host and need no license server, Even authorized user licenses for a Rational product is not specific to any version.
Activation kits are available for SDP (software delivery platform) products (Rational) and only activation kits are specific to the version of the product and they need to be imported on the Installation manager.
Refer to the link below on how to configure an activation kit on Installation mana
Now as we have an understanding of how the licenses work for the Rational products, we will try to understand how the licenses work for the family of products previously known as Telelogic and what are the different Telelogic products which are available.
The below sections will give us a complete understanding of how the licenses for Telelogic products works.
Only for TELELOGIC family of products floating licenses and Authorized user licenses are not version independent and Telelogic products don't have the concept of activation kits.
Whenever the client or the product is upgraded we also have a need to update the license file to ensure that it has appropriate maintenance renewal to support the newer version of the product.
TELELOGIC family of products works on Date based concept of licensing and your license file will have a maintenance end date in it and only product versions released prior to that maintenance end date which is specified in your license file will work and any version of the product which was released post to the maintenance end date will not work.
For Example: If you have Rational Doors floating license file with an maintenance end date of 2010.01.01 (JAN-01-2010) this will not work with Rational Doors version 9.5 as Rational Doors version 9.5 was released post 2010.01.01 (JAN-01-2010).
To understand this concept of Date based concept of licensing in clear refer to the white paper link below on Understanding date based concept of licensing: http
Also refer to the link below on how to apply the maintenance renewals for the Telelogic family of products: http
Find the list of TELELOGIC products below and as mentioned they all work on date based concept of licensing.
