This chapter describes the following topics:
• A description of the license manager and
the license file (Section 4.1)

4.1 Introduction
The license manager service runs on the head node and maintains licensing information for
software on the HP X C s y stem. You can find additio nal information on the FLEXlm license
manager at the Macrovision Web site:
http://www.macrovision.com
The license manager uses a license file to maintain all licenses associated with the H P XC
system. The /opt/hptc/etc/license/XC.lic file is the license file fo r the HP XC
system.
There may be instances when you need to update the HP XC license file, such as for
including a future additional product and updating the expiration. Update the license file
/opt/hptc/etc/license/XC.lic with the text editor of your choi ce.
The /var/log/syslic f ile is the log file for the license man ager.
4.2 Determining If the License Manager Is Running
Log in to the head node as su peru ser and execute the following comm ands to determine whether
or not the license manager is r unn ing :
# export COMPAQ_LICENSE_FILE=@nh
# lmstat -a
Output like the f oll owi ng indicates that the license man ager is not running:
Error getting status: Cannot find license
file (-1,359:2 "No such file or directory")
The ou tput of the lmstat comm and resembles the following when the license manager
is running:
