Understanding licensing for Rational Change 5.3

This topic contains information specific to IBM® Rational® Change licensing.

Rational Change is licensed using IBM Rational Common Licensing. For information about Rational Common Licensing v8.1.1, see the Rational Common Licensing information center.

License types

Rational Change supports the floating, named-user floating, and token license types. For a description of license types, see License type definitions in the Rational Common Licensing v8.1.1 information center.

For Rational Change users, the login name is seen as the user of the token license. To reserve named-user licenses for specific users, see Setting up the options file in the Rational Common Licensing v8.1.1 information center.

When configuring the options file for Rational Synergy and Rational Change, it is not necessary to put the default administrative users (ccm_root, ChangeAdmin, and csuser) in the INCLUDE list. The license file includes additional floating licenses for these users. Do not assign these licenses to other users because the products might fail.

How licensing works with Rational Change

There is a 30 minute minimum use time when Rational Change checks out a license. When a license is checked out, it stays checked out for at least 30 minutes, whether there is activity from the user. If the user exits or is inactive after that, the license is released.

When you install Rational Change, the license server information (port@host) is requested and persisted to the file CHANGE_APP_HOME/WEB-INF/wsconfig/license_data.txt.

Rational Change searches for license servers and license files in the following order:
  1. The environment variable TELELOGIC_LICENSE_FILE.
  2. The registry entry for TELELOGIC_LICENSE_FILE (or the ~/.flexlmrc file of the person who installed the license server on UNIX).
  3. The environment variable LM_LICENSE_FILE.
  4. The registry entry for LM_LICENSE_FILE.
  5. The location specified by the contents of CHANGE_APP_HOME/WEB-INF/wsconfig/license_data.txt.

If you move the license manager to a different system, you must edit the CHANGE_APP_HOME/WEB-INF/wsconfig/license_data.txt file or update the TELELOGIC_LICENSE_FILE (~/.flexlmrc for UNIX) or the LM_LICENSE_FILE system environment variable to contain the new value.
