Manage licensing for DevOps Code ClearCase

Determine whether to manage licensing with IBM Common Licensing, DevOps Code ClearCase®, or Asynchronous licensing.

IBM Common Licensing
IBM Common Licensing is not available to customers using ClearCase when it is provided by HCL. You can use IBM Common Licensing if ClearCase is provided by IBM.

On Windows platforms, use IBM Common Licensing to manage licenses with the License Key Administrator (LKAD) application powered by the FLEXlm license management tool.

The IBM Common Licensing License Key Administrator runs on a license server. To use this method, you must set up a license server and install the License Key Administrator client software.
Note: IBM Common Licensing by FLEXlm is not supported on Linux™ S/390®, Linux on System z®, and Linux PPC platforms. On HP IA-64 platforms, ClearCase supports IBM Common Licensing on ClearCase version 7.1 and later. For information about configuring licensing in cases where IBM Common Licensing is not supported, use ClearCase Licensing.
ClearCase Licensing
ClearCase Licensing is available when using ClearCase provided by IBM or HCL.
In the ClearCase Licensing model, a set of DevOps Code ClearCase and DevOps Code ClearCase MultiSite licenses is defined in a license database file. The license database file is stored on a license server host. Each license database file defines a set of user licenses, perhaps 5, or 10, or 100. A license database file is valid only if it contains a license authorization code, obtained from IBM Software Corporation or its designee. The network can have one license server host or several. Because each license server host runs a DevOps Code ClearCase server process, DevOps Code ClearCase must be installed on it.
Note: All DevOps Code ClearCase andDevOps Code ClearCase MultiSite products use the same license server. The license server is the host listed in /var/adm/clearcase/config/license_host.
Asynchronous Licensing

Asynchronous licensing is faster for the end-user in the normal case where a license is available because ClearCase does not wait for a response from the license server.
