License Borrowing with BORROW

out stays checked out from the license server until the borrow period expires—that license now
is used on your disconnected machine until the borrow period expires. Once checked out, it
remains checked out for the full borrow period. The borrow period cannot be renewed until the
period has expired.
Clearing the Borrow Period
Once you have borrowed all the licenses that you need for the current borrow period (defined
by the
LM_BORROW environment variable), prevent licenses for any additional features from
being borrowed by running
lmborrow -clear. This clears the LM_BORROW setting in the
registry (Windows) or
$HOME/.flexlmrc (UNIX). lmborrow -clear does not clear the
local information about licenses you have already borrowed.
Checking Borrow Status
To print information about borrowed features, issue the following command on the machine
from which they are borrowed:
lmborrow -status
The borrowing system does not have to be connected to the network to determine the status.
Returning a Borrowed License Early
To return a borrowed license before the borrow period expires, first reconnect the borrowing
system back to the network and then, from the same machine that initiated the borrowing, issue
the command:
lmborrow -return [-c license_file_list] feature
This option may or may not be allowed by your vendor. Check directly with your vendor to
determine if early borrowed-license return is supported.
Returning the license early has the effect of clearing the LM_BORROW setting for the vendor
daemon that serves the returned license.
