Certain computers can also be allowed to run or prevented from running applica-
tions. This can help to balance application usage when you want to prevent users
from running applications on heavily loaded computers or file servers.
How the Reservation File Works
The reservation file tells SentinelLM how many license tokens are reserved for
members of different groups. For example, the Sales department could be a
group with ten members for which 15 license tokens are reserved. The members
might be network users or specific computers on the network. The reservation
file might also tell SentinelLM that certain members of the group are excluded
from taking license tokens.
The groups defined must be mutually exclusive. Different groups for the same
feature should not have common users or computers. The number of license
tokens reserved for a feature cannot exceed the number of concurrent users spec-
ified in the license code for that feature.
When the license server receives a request, it checks whether the user making
the request belongs to a group. If so, and license tokens are available for that
group, the license server will issue the token(s) and decrement the token count
on the license server. Otherwise, requests will be serviced with tokens that have
not been reserved and that are available. Users for whom tokens have been
reserved have first call on available tokens.
At start up, the license server consults the environment variable, LSRESERV, for
the path and file name of the reservation file. If the variable is not set, the local
directory is searched for the file, lsreserv. If no file is found, the license server
assumes that no reservations exist.
