Types of LSF licenses
LSF uses two types of licenses:
◆ File-based DEMO licenses, which do not need a license server.
These are typically used while evaluating LSF and usually expire after 30 days. Each
FEATURE line in the license contains an expiry date and ends with DEMO. A DEMO
license usually licenses all LSF features and allows an unlimited number of LSF
servers and clients.
◆ Server-based permanent licenses, which require FLEXlm 7.2 or later and are used
in production installations.
Permanent licenses do not expire; they license only the LSF features you buy for a
specific number of hosts. Each
FEATURE line in the license ends with Platform.
Licenses are stored in a text file. The default name of the license file is
license.dat.
During installation, you specify the location of the license for
lsfinstall to install.
New installations typically use a DEMO license to install LSF and get it running, then
switch to a permanent license later, as described in “Setting up a Permanent LSF
License” on page 42.
