An additive license appends changes to an existing additive license of the same feature and version in a restrictive manner, so that only a single set of all the license properties is maintained. While the hard and soft limit of the two licenses are summed up for the entire duration of the license, only one set of start date (the latest of the two start dates) and expiry dates (the earliest of the two end dates) is maintained.
Click here to see what happens to the license properties for two additive licenses.
An aggregate license co-exists with multiple aggregate licenses of the same feature and version. The hard and soft limit of the aggregate licenses are aggregated, yet the start and expiry dates of the individual licenses strings are maintained in an independent manner. In active state, the combined hard limit helps in meeting short term spurts in license demand (termed as peak usage licensing).
When considering other license models, an aggregate license has a lower priority than an exclusive license, but a higher priority than an additive license.
Refers to the license generated using a Full license template in WlscGen or by using lscgen.
The mechanism used to find a License Manager with available license(s) in a subnet. Under broadcast, only v9.8.1 (or later) RMS License Managers will respond to licensed applications licensed using 9.8.1 (or later) version of licensing libraries. However, if the License Manager Compatibility-Mode Library is being used by the v9.8.1 (or later) clients, then even previous version of RMS License Managers will respond.
Defines the number of operations that can be executed by a token user (per hard limit). The license capacity also allows the customer to use an extra flag, along with hard limit, to control the number of applications that can be run simultaneously.
A technique used for authenticating the License Manager. The challenge strings (secrets) you define are encrypted within the license code, with only the License Manager knowing how to decrypt them. The License Manager will then compute an authentication response when challenged by a client to confirm its identity.
Refer to the WlscGen Help for details on defining secret strings.
Checking out license
A commuter license specific term. Refers to the process of issuing a license code for usage on a local system (such as when the user is commuting or not connected to the network).
Checking in license
A commuter license specific term. Refers to the process of returning the license back to the License Manager.
Refer to License Locking Criteria.
“Cloud-connected licensing” is software licensing managed from cloud to serve both on-premises or cloud-based software. It offers the ability for software vendors to have connectivity into the customer's software usage, which translates into better control and sustained monetization.
The hardware key (in parallel or USB form factors) used for locking a license to a system.
An exclusive license code completely replaces the old license with a new license.
A trial license-specific term. Refers to a trial license, whose trial days/hours are used-up.
Any functionality of your software that can be controlled independently via a license. It can be a complete application, a file, or distinct functionalities, like Print or Save.
A feature name identifies a license. All licensed applications must have a name by which they will be identified. The maximum characters for long code is 24, short code is 11, and predefined-single and multi-feature is 6 numeric digits.
An additional field that can be used with the feature name for uniquely identifying your application. For example, with feature name “Print,” the associated version can be 1.0. An upgrade of this feature can be identified with the 2.0 version.
This field is only available with long codes and the maximum characters allowed are 11.
Refers to a network license.
A grace license allows running the network application for a limited period (days/hours) even when the network is not accessible. It provides the convenience of using the application under unprepared circumstances, like enterprise network break-down or when the users are at home.
Stands for Global Unique Identifier—a unique 128-bit number that is produced by the Windows operating system or by some Windows applications to identify a particular component, application, file, database entry, and/or user.
The grace period for which the license can be held after releasing.
The licenses loaded in the memory for a feature-version, but are not serving the license requests. Only active licenses serve the client requests.
Internet Protocol version 4 is the fourth replication of the Internet Protocol (IP) and it is the first version of the protocol to be widely-deployed. IPv4 is the dominant network layer protocol on the Internet and apart from IPv6 it is the only protocol used on the Internet.
Internet Protocol version 6 (IPv6) is a network layer protocol for packet-switched internet networks. It is designated as the successor of IPv4, the current version of the Internet Protocol, for general use on the Internet.
IPX stands for Internetwork Packet Exchange. It is a networking protocol used by the Novell NetWare operating systems. Like UDP, IPX is a datagram protocol used for connectionless communications.
Also referred to as the license code in this documentation. A license is a string of encrypted characters that embody the terms defined in the license agreement for using the licensed software.
A license file can contain one or many license codes, of different vendors. The License Manager reads a license file to load licenses. The default name is lservrc.
Refers to the hardware key that is shipped by Thales to authorize license generation. It must be attached to the system on which licenses are being generated (using WlscGen, lscgen, or custom license code generator).
Refers to the Sentinel RMS license manager that centrally manages the licenses in a network.
Allow multiple instances of the licensed feature/application to share a single license token/key based on a common user name, host name, X-display ID, or custom sharing criteria.
This field is used for license aggregation by specifying different software vendor data, however, it does not participate in license aggregation. It has been introduced in RMS v9.4.1 for version 19 licenses and above. License software vendor information is the miscellaneous information that you can include as a part of the license code for identification. License software vendor information remains encrypted in all types of licenses (readable or encrypted), however, if the license string is decoded, the encrypted information will become readable.
A license version is always associated with the RMS licenses. It maps to the SDK version in which it was introduced. If a new feature or license property is introduced in the SDK, then the license version would be upgraded as the new feature would not be available with the earlier SDKs. For example, the aggregate licenses are introduced in SDK v8.5.x and cannot be generated with the previous version RMS SDKs. See the table below for the recent license versions and the corresponding SDKs:

Refers to the arrangement of active licenses for the various feature-version combinations. The license requests are served from the license table.
A general term used to refer to the software licensed using Sentinel RMS.
Refers to a unit of time specified for the license to send updates to the License Manager. After the 80% of this time period is elapsed, the licensed application sends an update call to the License Manager to notify its alive status. A license must be renewed by the application on a regular schedule or the license will be reclaimed.
Leader (License Manager)
The operating License Manager with the highest priority indicated in the lservrlf file.
Long license codes allow use of more licensing features and contain more information when compared to short-numeric license codes.
When a majority (over half) of the redundant License Managers must be up and running for a request for that active license to be serviced. For example, if you have defined five redundant License Managers and majority rule is in effect, at least three of them must be up and running or a request for that license will fail.
When a single license code licenses a range of features. The multi-feature license code is typically used to license a set of applications with a single license code.
A license meant for networked environments, such as in client-License Manager architecture when centralized license management is desired. Here, the license management functions are moved out of the licensed application to an external component—the Sentinel RMS License Manager (License Manager). The License Manager can run on any computer on the network, including a computer on which the licensed application is run.
The locking code format for the version 11 and later licenses. The Wechoid and echoid utilities allow generating both the new style and old style locking codes.
Network Interface Card.
A license that does not have restricted usage, like in a trial license which expires after certain time period—days/hours/date. A normal license can have other properties associated with it. For example, it can be locked or unlocked.
The locking code format for the version 10 and older licenses. The Wechoid and echoid utilities allow generating both the new style and old style locking codes.
Peak Usage Licensing
A licensing solution to fulfill license demands during peak periods.
Since the v8.5.0 release, perpetual license is renamed to Repository License.
Refers to the licensing data that is retained on the local computer in the non-volatile storage.
A numeric value that decides the priority of a license compared to others. As of now, only trial licenses can have precedence associated with them.
Private Vendor Information
Miscellaneous information that you can include as a part of your license code for identification. The private software vendor information will remain encrypted in all license models (whether readable or encrypted).
Refers to the various attributes a license can have.
Miscellaneous information that you can include as a part of your license code for identification. The public software vendor information will remain encrypted in encrypted licenses and readable in readable licenses, respectively.
License queuing allows a licensed application to wait for a license if a license is present on the network, but not available. The License Manager maintains all queued requests pertaining to the License Manager in a "first in, first out" basis. Once a license becomes available within a pre-determined time interval, the application can retrieve the license and the licensed application starts.
Refers to a pool of License Managers that provide failover and back-up in case one License Manager goes down. This is to provide uninterrupted service to the network users as they seamlessly switch over to using a new License Manager.
A network license that it is checked out automatically from the License Manager (unlike the manual check out of a commuter license) after the first successful license request. However, it needs be checked in to the License Manager after use in the same manner as a commuter license.
Stands for Rights Management System. Refers to Sentinel RMS.
Software Development Kit.
Sentinel RMS Envelope
Sentinel RMS Envelope provides automatic IP protection for your software. It wraps your programs with a protective shield and also allows you to configure protection features to enhance the overall security of your software. Implementing Sentinel RMS Envelope does not require you to alter your software's source code.
The device driver for accessing the hardware keys used by Sentinel RMS, that is, the Computer ID key and license meter key. The Sentinel System Driver includes drivers for both the parallel port and USB port keys.
Refers to all-numeric short license codes. For version 11 licenses, these can only be generated using the predefined license templates in WlscGen and lscgen.
The software vendor’s public/private key pair for license generation with default version of 1 is referred to as Signing Key Index. Likewise, 0 is the Signing Key Index for the older version unsigned licenses (v17 and below).
A license typically meant for non-networked or single user environments (such as home users). The various license management functions, including the License Manager, are embedded within the licensed application.
A unit of license associated with a running instance of the protected application.
A temporary license that allows software usage for fixed days or hours, beginning from the day/hour it is first used.
A license that allows version and/or capacity upgrades for existing license users.
A Universally Unique Identifier (UUID) is an identifier standard used in software construction, standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). UUIDs enable distributed systems to uniquely identify information without significant central coordination.
