Reservation Groups

Reservation Groups are used to restrict usage and access rights to products for particular users, computers or groups.

This is an additional security measure and can help balance the use of products or features between groups or departments.

For example from a corporate ‘pool’ of 20 licences, 5 could be assigned to a Planning group, 10 could be assigned to an Infrastructure group and 5 for general use.

How it works

When the licence server receives a request, it checks if the requesting user belongs to a group.
If yes (and licences are available for that group) the licence server will issue the licence(s) and reduce the count on the licence server.
Otherwise requests will be serviced with licences that have not been reserved and are available. (Users for whom licences have been reserved have first call on available licences).
On start up, the licence 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 licence server assumes no reservations exist.

The total number of licences assigned to groups cannot be greater than the total licence pool.

Note: Group reservations are only meaningful with a network licence server; they cannot be used to manage features installed locally.Unreserved licences can be used by anyone.

WLMADMIN does not keep track of the number of licences being reserved. If the number is exceeded, reservation groups lower down the order will never get licences.

For example if there are 10 licences, GroupA has 6, GroupB has 4 and GroupC has 2, then GroupC will never get a licence, even if Groups 1 and 2 are not fully used.
