本文详细介绍了 Rational ClearCase 的许可证使用流程。当用户运行 ClearCase 命令或 GUI 时，会进行许可证验证检查。如果用户已有许可证，则直接运行命令；如果没有，则尝试从许可证服务器获取。许可证默认有效时间为60分钟，期间只要用户执行了 ClearCase 相关操作，许可证的有效时间将被重置。

When a user runs a Rational ClearCase client utility, such as cleartool or a GUI program, that utility attempts to obtain a license. If it gets one, the user can keep the license for an extended period. Entering any Rational ClearCase command renews the license. If the user does not enter a Rational ClearCase command for a substantial period—by default, 60 minutes—another user can take the license.

简单的说：当你开始使用ct时，就会获得一个license，但是这个license是有时间限制的，默认是60秒；只要你在这60秒内什么都没有做，你的license就有可能被分配给别人，反过来只要你使用了，这60秒的限制就会被重新设置陈60秒，重新开始计时。

以下是获取license的步骤：

Whenever a user runs a Rational ClearCase command or GUI, a license-verification check is made. If the user already has a license, the check succeeds and the command or GUI runs. If the user does not have a license, the following steps occur:

1. The Rational ClearCase client software looks for the name of the license server host.

2. The command or GUI communicates with the license server process on the license server host, to see whether the user can get a license. (The license server process is actually the albd_server, performing these duties in addition to its other tasks.)

3. If a license is available, the license server grants the user a license and the command or GUI runs.

4. If no license is available, the license server returns a message to that effect and the command or GUI exits with an error message.
