rlftool is a command line utility for Windows and UNIX. On a Windows computer, use rlftool from within an MS-DOS window. However, you may find using the Windows-interface WRlfTool program more convenient than using rlftool.
If you are editing an existing redundant license file, to avoid synchronization problems because someone else is adding licenses in the redundant license file while you have it open, we recommend you make a copy of the file under another name, make your changes, and then rename it back to its original name when you are done. The changes you make to the redundant license file will not take effect until you copy the changed file to a redundant License Manager in the pool (or edit it directly on the License Manager using the precautions discussed above) and then restart that server.
