Specifying a license server host

Each Rational® ClearCase® host must be configured to obtain licenses from a specific license server host. This configuration typically occurs during installation, and is often taken from a site default specified by the Rational ClearCase administrator.

Note: A license server hosted on any platform can provide licenses for all types of Rational ClearCase hosts. However, when you use a Windows® computer as the license server host, it must be a member of a domain in which accounts are defined for all users, including those who use Linux® and the UNIX® system, who will acquire licenses from it. For more information, see Common user and group names.

To reconfigure a Rational ClearCase host to use a different license server, do one of the following:

On Linux and the UNIX system, the license server host name is stored in the file /var/adm/rational/clearcase/config/license_host. You can edit this file with any text editor to specify the name of a new license server host.
On Windows, the license server host name is specified on the Licensing page of the ClearCase program in Control Panel as the value Use license server on host:.
You can also use the Rational ClearCase Administration Console to change the license server used by any Rational ClearCase host in your network:
1. Go to the host node for the host whose license server you want to change. This can be the My Host node or a subnode of the ClearCase Network node in Rational ClearCase Administration Console, or the top-level node in ClearCase Host Administration.
2. Click Action > Properties. This command opens a window in which you can change the host’s license server. To change the license server for a remote host, the host must be configured to allow remote administration, and you must be a privileged user.

Note: When a user accesses multiple Rational ClearCase hosts that use different license servers, the user acquires a license from each server. When a user accesses multiple Rational ClearCase hosts that use the same license server, the user acquires a single license.
