License Server Busy: How to Roll Over to Another
The environment variable can be configured to do the rollover to the next server if it cannot find the license local or if the local machine is down. The UGS_LICENSE_SERVER variable can have the servers added to the value and separated with a semicolon. UGS_LICENSE_SERVER=28000@SERVER1;28000@SERVER2 SPLM_LICENSE_SERVER=28000@SERVER1;28000@SERVER2
On UNIX, the license search path entries are separated by colons; on Windows, the entries are separated by semicolons.
