License Management with FLEXlm and COBOL

FLEXlm Utilities

If a license ﬁle is not speciﬁed with the -c option, lmdown operates on

the license ﬁle speciﬁed by the LM_LICENSE_FILE environment

variable. If a LM_LICENSE_FILE environment variable is not found, it

tries to use /usr/local/flexlm/licenses/license.dat. In most

cases, specify the exact location of the license.dat ﬁle you want

lmdown to operate on.

You usually only need to shutdown and restart licensing if you have

changed a vendor daemon options ﬁle.

IMPORTANT When shutting down redundant servers, there is a one minute delay

before the servers shut down. Never use kill -9 to shut down the

license servers.

IMPORTANT Restricting the use of lmdown and lmremove

Since lmdown shuts down the FLEXlm licensing, thereby removing the

licenses from active processes, it is advisable that the system

administrator restrict its use to license administrators only. This can be

accomplished by starting lmgrd with the -p -2 option. This will cause

lmgrd to allow only a member of the UNIX “lmadmin” group to execute

lmdown, lmremove, or lmreread commands. If the UNIX group

“lmadmin” does not exist, then only a member of group 0 will be allowed

access to these commands. If you want to completely disable the lmdown

and lmremove utilities, start lmgrd with the -x option.

Using lmhostid

This utility can be used to identify the correct hostid value (that must

match the hostid value on SERVER lines in the license.dat ﬁle if the

machine is a server) on any machine support by FLEXlm. Its usage is:
