HP Micro Focus Object COBOL/UX Release Notes for Version B.13.35

28 Chapter 3
License Management with FLEXlm and COBOL
• A network that allows TCP/IP communication between workstations
and servers. This is normally included in the HP-UX operating
system.
• The FLEXlm software installed on machines that will be the license
servers.
•Alicense.dat file that contains the FLEXlm file entries.
To redeem your licenses and receive the license.dat file entries,
follow the directions in “Redeeming Your Licenses” on page 34.
FLEXlm Components
FLEXlm has four major components:
• The license manager daemon (lmgrd)
The license manager daemon (lmgrd) resides on a central machine,
the license server. lmgrd controls, serves, and monitors the pool of
licenses available on the network under FLEXlm. It also starts and
restarts the vendor daemons. You can have three license servers,
using the others as redundant or backup servers in case the first one
goes down. With redundant servers most, if not all, application
clients will continue executing without any noticeable delay.
• The vendor daemon (HPCUPLANGS)
In FLEXlm, licenses are handled by running processes. There is one
process for each vendor who has a FLEXlm-licensed product on the
network. This process is called the vendor daemon. The vendor
daemon keeps track of how many licenses are checked out, and who
has them. The vendor daemon used by HP Micro Focus Object
COBOL/UX is named HPCUPLANGS.
• The license file (license.dat)
The licensing data is stored in a text file named license.dat. The
license file, created by the HP license administrator, contains
information about the license server and vendor daemons on the
server. The license.dat file contains SERVER and vendor
DAEMON specification lines and INCREMENT lines containing
information about the license client (HP Micro Focus Object
COBOL/UX).
