CoreMedia CMS uses file based licenses. Only
server applications (Content Management Server and
Live Servers) have a license file on their own. All other
applications are licensed by the license file of the server they connect to. The license file
will be read in from the directory defined in the property cap.server.license
and will be validated each time the licensed
application starts. If the license is valid, the application will start properly. CoreMedia
distinguishes between two kinds of licenses:
Time-based license
Limits the use of an application to a specific period.
IP-based license
Limits the use of an application to a specific computer, defined by its IP address and/or host name.
Both license types can define a valid CoreMedia CMS release using the
release
attribute. If you use time-based licenses, the application will not start if the license has
expired. In addition, the license file defines a grace period. You receive a notification, after exceeding the
grace period.
Both license types may limit the number of clients which can connect to the application simultaneously. This is achieved, using the following concepts:
Named user
A named user is a specific CoreMedia CMS user, known by the system. Each service connects as a user to the server. The attribute
named-users
defines the maximum number of users which are allowed to use a specific service.Concurrent user
Concurrent users are users which are connected simultaneously to the server. The attribute
concurrent-users
defines the maximum number of named users which are allowed to connect simultaneously.Multiplicity
A named user may connect several times to the server (use Studio in different browsers, for example). The attribute
multiplicity
defines the maximum number of allowed connections for a named user.
Use the utility sessions
(see Section 3.13.1.8, “Sessions” in Content Server Manual) to get this information and the utility
usedlicenses
(see Section 3.13.2.21, “Usedlicenses” in Content Server Manual) to free used licenses. If the built-in user admin
(user
ID 0) has no open sessions, that user may log in to the Content Server even if the licenses
are otherwise exhausted. This makes it possible to start the utilities for recovering from a
license shortage in any case.
A server license can be exchanged at runtime without restarting the server. The property
cap.server.license
defines the location of the
license file. When the file or location changes, the server will automatically reload the license.
Reloading the license will not cause any open sessions to be closed, even if the new license is
more restrictive than the old one.
Example:
<LicenseConfiguration> <Server type="production"/> <Property name="licensed-to" value="Customer"/> <Property name="workflow" value="enabled"/> <Property name="elastic-social" value="enabled"/> <Property name="personalization" value="enabled"/> <Property name="analytics" value="enabled"/> <Property name="livecontext" value="enabled"/> <Property name="brand-blueprint" value="enabled"/> <Property name="asset-management" value="enabled"/> <Property name="id" value="10394"/> <Valid from="01.01.2015" until="01.12.2015" grace="01.11.2015"/> <License service="editor" concurrent-users="30000" named-users="200"/> <License service="system" concurrent-users="5" named-users="25"/> <License service="webserver" concurrent-users="15" named-users="50"/> <License service="studio" concurrent-users="15" named-users="50"/> <License service="workflow" concurrent-users="600" named-users="200"/> <License service="importer" concurrent-users="2" named-users="25"/> <License service="publisher" concurrent-users="33" named-users="200"/> <License service="debug" concurrent-users="100" named-users="100"/> <License service="replicator" concurrent-users="5" named-users="10"/> <License service="feeder" concurrent-users="2" named-users="10"/> </LicenseConfiguration>
