Citrix Broker - Licensing
SHORT DESCRIPTION
Overview of broker licensing configuration.
LONG DESCRIPTION
As part of the licensing setup for a site, the types of product licenses
used by the broker when creating connections to virtual desktops or
applications can be configured using the Central Configuration Service SDK.
The following licensing related properties can be specified using the
Set-ConfigSite cmdlet:
o LicensingModel - Sets the licensing model to use. Values can be
'Concurrent' or 'UserDevice'.
o ProductCode - Specifies which product license is supported by the
site. Values can be �MPS� for XenApp licenses or �XDT� for XenDesktop
licenses.
o ProductEdition - Sets the licensing edition to use.
A license matching the specified model, product code, and edition must be
available within the site's license server in order for the broker to grant
licenses.
These properties are part of the site object returned by the Get-ConfigSite
cmdlet.
CONCURRENT LICENSE MODEL
A concurrent license is tied to a XenDesktop session. When a user launches a
session, a license is checked out to that session. When a user logs off
from a session, the license is checked back in again, making it available
for another session.
USER DEVICE LICENSE MODEL
With user device licensing, the license server automatically assigns
licenses to users or devices based on usage:
o User licensing allows users to access their desktops and applications
from multiple devices.
o Device licensing allows multiple users to access their desktops and
applications from a single device.
When users or devices connect to an application or desktop, they consume a
license for a 90-day license assignment period. The assignment period begins
when a connection is made, is renewed to the full 90 days during the life of
the connection, and expires (allowing reassignment) 90 days after the last
connection terminates. A license assignment can be manually ended before the
90-day period elapses using the udadmin command line installed on the
license server.
LICENSING STATE
The broker site contains the following properties related to licensing
state:
o LicensingGracePeriodActive - Reports if the broker is in licensing
grace period.
o LicensingOutOfBoxGracePeriodActive - Reports if the broker is in
out-of-box grace period.
o LicensingGraceHoursLeft - The number of grace hours remaining, if the
broker is in grace period, else it is null.
o LicensedSessionsActive - The number of active, licensed sessions.
o LicenseGraceSessionsRemaining - The number of grace sessions available,
if the broker is in licensing grace period, else it is null.
These properties are part of the site object returned by the Get-BrokerSite
cmdlet.
LICENSE SERVER TEST
The broker SDK cmdlet Test-BrokerLicenseServer checks whether or not a given
server can be used as a license server by the broker.
RESETTING LICENSE SERVER CONNECTION
The broker SDK cmdlet Reset-BrokerLicensingConnection resets the broker's
connection to the license server.
LICENSE BURN-IN DATE
The version of the product that is supported within the site is denoted by a
licensing burn-in date. This date can be accessed through the
LicensingBurnInDate field of the site object returned by the Get-ConfigSite
cmdlet.
