License Servers
The license server is a lightweight application that serves licenses to products running on any
operating system.
A license server can run on a low-end machine or a machine with spare cycles. For example, a
license server running on a Solaris UltraSparc-60 serving 100 different licenses to 200 product
instances, used 50MB of memory, 5 minutes of CPU time per week, and 100MB of disk space
per year.
To download the license server software and installation instructions, go to the SySAM
Standalone License Server Install page at
http://www.sybase.com/sysam/server
and select the
download link.
Note: You cannot start the license server until there is at least one served license saved to the
licenses directory on the license server host machine.
Determining Host IDs
When you generate licenses at SPDC or SMP, you must specify the host ID of the machine
where the licenses will be deployed.
• For unserved licenses, specify the host ID of the machine where the product will run. If you
are running a product with per-CPU or per-CHIP licensing that supports SySAM sub-
capacity, and you want to run the product in a virtualized environment, see
SySAM Sub-
capacity Licensing
in the
SySAM Users Guide
for information about determining the host
ID for unserved licenses.
• For served licenses, specify the host ID of the machine where the license server will run.
SPDC or SMP remembers the host information so that you can select the same license server
when generating additional licenses.
To determine the host ID of the machine, run the lmutil utility from a terminal window or the
Windows command prompt. For example:
lmutil lmhostid
Note: You can download the lmutil utility from the Flexera Software Web site at
http://
www.globes.com/support/fnp_utilities_download.htm
.
You can also determine the host ID using native operating system commands. See the
Frequently Asked Questions topic "What is my Host ID?":
