How can I make use of multiple license sources?

Applies to: DS-5, RealView Development Suite (RVDS), Tool Licensing (License Management)

Scenario

I want to ensure that my tools will try to check out features from one license source (for example a local node locked license) before additional sources are tried.

Answer

The recommended way to control how ARM licenses are found is to create an environment variable called ARMLMD_LICENSE_FILE and assign to this the location of the license source.

For a Windows PC with a node locked license this will typically look something like:

ARMLMD_LICENSE_FILE=C:\Program Files\ARM\FlexLM\license.dat

If a valid license feature cannot be found from this location an error will be reported.

However, you can add additional locations to this environment variable to extend search path. For example:

ARMLMD_LICENSE_FILE=C:\Program Files\ARM\FlexLM\license.dat;8224@my_server

In the above instance the license server 'my_server' will only be used if the license feature cannot be found within the original location.
