When you install IBM Rational products that share components, or shell share, you can open a product that subsequently checks out a floating license key for another product. For example, suppose you install Rational Software Modeler and IBM Rational Software Architect in the same shell, C:\IBM\devtools. Both packages have been enabled for Rational Common Licensing (powered by FLEXlm software) to use floating licenses. When the Rational Software Modeler attempts to check out a floating license for shared components and fails, it can then attempt to check out an available license for Rational Software Architect.
You can use the Manage Licenses wizard in the IBM Installation Manager to change the version 7.0 license usage order. You may want to customize the license usage order in some cases. For example, change the order to have a product search for a specific license key first.
