General Description: What are the differences between node-locked and
floating licenses?



Solution 1:

Xilinx is creating two kinds of licenses for M1.

 1: a floating, counted, license.

 2: a node-locked, uncounted, license.

If a license is floating and counted, then the server and daemon (lmgrd and
xilinxd) must be running.

If a license is node-locked and uncounted, then the server and daemon are NOT ne
eded.

A node-locked license has a hostid in the FEATURE line(s).  It can be used
ONLY on the machine whose hostid is in the line.  In our case, it also has
a zero (0) for the number of users; that means we're not counting how many
copies are used at the same time.

Here is a typical floating FEATURE.  It allows only one machine at a time,
but that user can be on any machine.  It also requires a SERVER and a
DAEMON line, which are not shown here.

FEATURE PR-4EX-WS xilinxd 1.000 28-JUL-97 1 C91A9464B55472B5CB4D \
	"XSJ_juliette"


Here is a typical node-locked FEATURE.	It allows only one specific machine,
with hostid 0C32-D4EC, to run the software; but any number of users can be
using the software on that machine.

FEATURE ALI-BETA-PC xilinxd 1.000 28-JUL-97 0 1C2254D4B32C755B2ED6 \
	"XSJ_davet" DISK_SERIAL_NUM=c32d4ec


BOTH PC users and Workstation users licenses can come from the same license
server and license file.  It is possible to have both types of FEATURES in
the same file.	 In that case, the server and daemon must be running for the
floating, counted license.  In a mixed license, the node-locked, counted
licenses should be at the front of the file, AHEAD OF the SERVER and DAEMON
lines.	That way the programs on those machines don't have to go look on the
network for a license, and won't grab a shared license.
