%SYSTEM.License

abstract class %SYSTEM.License extends %SYSTEM.Help

The %SYSTEM.License class provides an interface to the Cache License API.

Some class methods are implemented in the special $system object and can be accessed with the $SYSTEM.License.Method() syntax. The system object methods are identified in the method documentation as $SYSTEM.License.XXX.

Example: Set Success=$SYSTEM.License.Login(UserIdentifier)

Other methods are implemented as class methods of the %SYSTEM.License class and can be accessed by the usual ##class(%SYSTEM.License).ClassMethodName() syntax. The special $system object methods can also be accessed in this way.

Example: Do ##class(%SYSTEM.License).ShowSummary()

The %SYSTEM.License class includes a number of license usage reports and queries. The data source is either the local instance or the license server, or in some cases both. The data source is identified in the individual query descriptions.

Comparing data from the license server with data from an individual Cache instance can sometimes lead to apparent inconsistencies. These inconsistencies can be explained by understanding the operation of the license server. Each Cache instance maintains a database of its license use and independently controls connections to itself. When multiple instances share a Cache license key, the license server coordinates the counting of license usage among all instances sharing the license key. Each instance periodically sends messages to the license server describing any changes that have occurred to the local license database since the previous message. Each instance controls logins and logouts locally and can continue to permit connections if communication with the license server should be interrupted. The license server coordinates the activity of the participating instances by preventing them from collectively exceeding the authorized license count.

The periodic nature of license server updates is one source of temporary inconsistency between the license server's view of license use and an individual Cache instance's view. License server and Cache instance counts of license usage will be temporarily out of sync if a number of logins or logouts have not yet been sent to the license server at the time usage reports are requested from the license server and from the local instance. This inconsistency is short lived because updates are sent to the license server about every 15 seconds.

It is also possible for the active license server to be stopped, perhaps because the host on which it is running has shut down or because the instance that started it is being upgraded. In this case, the replacement license server's view of license use will be incomplete until all participating instances have reported their license use.

Methods

classmethod ActiveServerCount(ByRef Status As %Status) as %Integer
$SYSTEM.License.ActiveServerCount() returns the number of instances (including the current instance) currently using the active license key. It executes the $SYSTEM.License.KeyOrderNumber() query and counts the number of instances using a license with the same OrderNumber value as the active license key on the current instance. Error status is returned by reference in the Status argument.
classmethod ApplicationServerLogin(AppName As %String = "", Keyword As %String = "", ByRef Status As %Status) as %Integer
##Class(%SYSTEM.License).ApplicationServerLogin(AppName, Keyword, Status) returns 1 if the number of instances using the active license key used by this instance (including this instance) does not exceed the number authorized by the "Keyword" item in the "AppName" application license section. Error status is returned by reference in the Status argument.
final classmethod CKEY()
Display the active license key to the current device.
The fields of the [License] section of the installed cache.key file are displayed followed by a brief accounting of license usage, including:
  • License units currently available.
  • Minimum number of license units available at any time since the instance started.
  • Maximum number of license units available.
License usage levels are obtained from the current Cache instance.
This report is identical to those produced by CKEY^%SYS.LICENSE and ^CKEY.
classmethod CSPGrace() as %Integer
$SYSTEM.License.CSPGrace() returns the current number of CSP sessions in the grace period.
classmethod CSPUsers() as %Integer
$SYSTEM.License.CSPUsers() returns the current number of CSP users.
final classmethod CheckAppLicenseUsed(AppName As %String, FeatureKeyword As %String) as %String
$SYSTEM.License.CheckAppLicenseUsed(AppName,Keyword) iterates through the internal license use tables counting the number of times an application license keyword has been taken. The resulting count is compared to the internal usage count maintained for the application license keyword. The internal count is adjusted if it does not agree with the counted value.
The return value is a string containing "CountedUsage,InternalUsageCountBeforeAdjustment,AppLicensesRecovered"
Throws an "INVALID ARGUMENT" error if AppName is not licensed. Returns "" if FeatureKeyword is not licensed. Returns "" if the application/keyword license value is not a number because only numeric application features can be taken and released. AppName is of the form Company.Application for protected application license sections or Application for unprotected application license sections.

Example: $SYSTEM.License.CheckAppLicenseUsed("MyCompany.MyApp","MyAppFeature")
classmethod CheckKeyForUpgrade(NewKeyFile As %String, ByRef Reductions, ByRef Status As %Status) as %Boolean
$SYSTEM.Licence.CheckKeyForUpgrade(NewKeyFile,.Reductions,.Status) compares the active license key with the key in file NewKeyFile to determine if the new license key authorizes less capability than the active license. It returns TRUE (1) if any capabilities authorized by the active key are absent in the new key or of lessor capacity. It returns FALSE (0) if all capabilities of the active license are equaled or exceeded by the license in NewKeyFile.

Arguments:
  • NewKeyFile (input): full path and file name of new license key file.
  • Reductions (output by reference): an array of capabilities that are smaller in the new key than in the active key.
  • Status (output by reference): an error status returned by IsValidKey when it was called to examine the new license file.
The Reductions array can contain the following elements:
  • Reductions("Cores")=$lb(OldCores,NewCores)
  • Reductions("Server")=$lb(OldServerValue,NewServerValue)
  • Reductions("Users")=$lb(OldUsers,NewUsers)
  • Reductions("Product")=$lb(OldProduct,NewProduct)
  • Reductions("LicenseType")=$lb(OldType,NewType)
Reductions in licensed features will be indicated by Reductions("Feature", FeatureName)=$lb(OldFeatureValue,NewFeatureValue). License parameters which have not changed or which have increased in capability will not be shown.
classmethod ClearDurationCounts() as %List
$SYSTEM.License.ClearDurationCounts() sets the collection area of the LoginDuration query to all zeros and returns the counts prior to change. Requires the %Manager role.
classmethod ConnectionCount(UserIdentifier As %String) as %Integer
$SYSTEM.License.ConnectionCount() returns the number of connections currently associated with the given UserIdentifier. The range of return values is normally 0 through MAXCONNECTIONS. If the value exceeds MAXCONNECTIONS then more than the allowable number of concurrent connections were attempted for a given ID and the system has transitioned to a mode of one connection per license for this UserIdentifier.

The SectionName value is case sensitive and can contain as many as 47 alphanumeric characters. It cannot contain a period. Features licensed are authorized by properties in the application section represented as keyword=value pairs. Keywords are case sensitive and can contain as many as 47 alphanumeric characters. The total length of keyword=value cannot exceed 255 characters. Licensed items with a numeric value are counted by the license software (see TakeApplicationLicense() and ReturnApplicationLicense()). Licensed items with a text value can be retrieved with GetAppLicenseValue(AppName,FeatureKeyword). The entire application license can be retrieved with GetAppLicense(AppName,getvalues). An application license section can contain 16536 characters including a terminating NULL character appended internally to each keyword=value line.

Example application license section:

[MyApplication]
Concurrent Users=50
LabTech=20

To acquire a license for a particular connection, provide a UserIdentifier (%String). UserIdentifier can be an arbitrary identifier determined by the application, but it must uniquely identify the user connecting to Cache. The client IP address will be appended to the identifier provided separated by an "@" sign to form the complete license identifier. If the input string contains an '@' character, the string will be truncated and the client IP address wil be appended following the first '@' character. The UserIdentifier cannot contain the '|' character. If the '|' character is found, it will be replaced with the forward slash ('/') character. The total length of UserIdentifier can be no more than 64 characters including the '@' character and the IP address appended by the system. If the input UserIdentifier exceeds 64 characters, $SYSTEM.License.Login will return an ILLEGAL VALUE error.

This function will relinquish a license if the session/process is already holding one under a different identifier and it will obtain a new one on the behalf of the user ID provided.

If the MAXCONNECTIONS connection limit per user is exceeded, the usual transition to one-license-unit-per-connection will apply to this user identifier.

If a failure occurs because no additional license units are available, the session/process will revert to the original license state and the function will return 0. If the call is successful it will return a positive integer which is the number of connections currently associated with "UserIdentifier@ClientIP" (including the one just consumed).

classmethod MaxBufferPool() as %Integer
$$SYSTEM.License.MaxBufferPool() returns the maximum buffer pool size authorized by the active license key. Zero indicates unlimited.
classmethod MaxCSPGrace() as %Integer
$SYSTEM.License.MaxCSPGrace() returns the maximum number of CSP sessions in the grace period at any time since the instance started or the CSPGrace maximum counter was reset.
classmethod MaxCSPUsers() as %Integer
$SYSTEM.License.MaxCSPUsers() returns the maximum number of concurrent CSP users since the instance started or the CSPUsers maximum counter was reset.
classmethod MaxConnections() as %Integer
$SYSTEM.License.MaxConnections() returns the maximum number of connections a user can make while consuming one license unit.
classmethod MaxDB() as %Integer
$SYSTEM.License.MaxDB() returns the maximum number of non-system Databases authorized by the active license key. Zero indicates unlimited.
classmethod MaxECPServers() as %Integer
$SYSTEM.License.MaxECPServers() returns the maximum number of ECP servers authorized by the active license key.
classmethod NetworkEnabled() as %Integer
$SYSTEM.License.NetworkEnabled() returns 1 if the Cache license key enables ECP, 0 if it doesn't.
classmethod ProcAvailable() as %Integer

classmethod PublicWebAppUser() as %Integer
$SYSTEM.License.PublicWebAppUser declares an application to be a public web application for the purpose of a Web Add-on license. This system method requires that the active license key be a Real Time license or have the Web Add-on feature enabled. The return value is 1 on success, 0 on failure. Failure indicates the license key does not support this option. The PublicWebAppUser system method must be called from the OnStartSession method of the Session Events class defined for the CSP application as follows:

    1) Create a subclass of the %CSP.SessionEvents class and define a method to handle the OnStartSession event. Call $system.License.PublicWebAppUser() in the OnStartSession class method.

    2) Define this class as the Event Class for the CSP application.

    Management Portal -> System Administration -> Security -> Applications -> Web Applications

    Enter the %CSP.SessionEvents subclass in the " Event Class:" box.

    3) Insure that "Unauthenticated" is checked for "Allowed Authentication Methods".

    Example: The following code could be placed in ClassMethod OnStartSession of the class extending %CSP.SessionEvents that acts as the session event handler for the public application.
      try { s x=$system.License.PublicWebAppUser() } catch { /* log error */ }
      q $$$OK
      
classmethod PublicWebAppUserCount() as %Integer
$SYSTEM.License.PublicWebAppUserCount returns the current number of public web application connections active.
classmethod PublicWebAppUsersMax() as %Integer

classmethod ReadDurationValues() as %List
$SYSTEM.License.ReadDurationValues() returns the upper limit in seconds each histogram bucket represents. The values are returned as a list with 5 elements. The sixth value is not provided because there is no upper limit. Returning time bucket values in a list permits the number of buckets and their values to be changed in the future with little impact on the code.
classmethod ReturnAllCSPApps(session As %CSP.Session) as %Status
$System.License.ReturnAllCSPApps(SessionId)
Called by the CSP Daemon when it deletes a session object.
classmethod ReturnApplicationLicense(AppName As %String, FeatureKeyword As %String = "Concurrent Users", ByRef Released As %Integer, session As %CSP.Session) as %Status
$SYSTEM.License.ReturnApplicationLicense(AppName,FeatureKeyword,.released,session)
Return (release) a license unit for an application license and feature. The license feature value must be numeric in the application license section. Releases the license resource associated with the licensed user Id of the current process, or the session license Id in the case of CSP.

Arguments:
AppName: The 'Company.Application' value from the section name in cache.key for protected application license sections, or the name of the unprotected application license section loaded with LoadAppLicenseFile().

FeatureKeyword: The application feature keyword being released. If the FeatureKeyword is omitted, the default value is "Concurrent Users".

Released: Returns 1 if the license was released, 0 if the license was not held.

session: The CSP session Id this application license should be taken for if the application license is being taken for a session, not the current process. If this argument is not present and %session is defined and is a %CSP.Session object, then the application license will be taken for the %session object. If neither the session argument nor the %session variable is defined, the license is taken for the current process.

Return value: $$$OK, or error status.
An error status containing an INVALID ARGUMENT error will be returned if no license has been loaded for AppName.

Example: $SYSTEM.License.ReturnApplicationLicense("MyCompany.MyApp","MyAppFeature"[[,.Released[, session]])
classmethod SetConnectionLimit(MaxCon As %Integer) as %Integer
$SYSTEM.License.SetConnectionLimit establishes the maximum number of connections permitted per user on this instance. This enables a system administrator to prevent a user from making so many connections to a Cache instance that they consume all available license units. Calling $SYSTEM.License.SetConnectionLimit($SYSTEM.License.MaxConnections()) permits a user to make the maximum connections permitted but prevent transitioning to the license unit per connection state, insuring the user will consume no more than one license unit. A zero argument removes the limit. The failure to obtain a license will be indicated in the normal way. For example, a call to $system.License.Login() will return zero (0) while a failure to log in to a new terminal connection will receive a error. However, these license failures will not be reported in the console log. The method returns the former maximum value.

The limit applies only to the local instance. If a Cache MultiServer license is shared among several instances it is still possible to exceed $SYSTEM.License.MaxConnections() over all instances. This can be avoided by setting the limit low enough on each instance that the combined connections to all instances will be unlikely to exceed $SYSTEM.License.MaxConnections().

$SYSTEM.License.SetConnectionLimit reqires access to the %Admin Manage resource. It is suggested that customers call this API from SYSTEM^%ZSTART.
classmethod SetUserLimit(MaxLU As %Integer) as %Integer
$SYSTEM.License.SetUserLimit establishes the maximum number of license units that this Cache instance will consume. This permits a system manager to prevent a Cache instance from consuming all the license units in a MultiServer key shared among multiple Cache instances. The Method returns the former maximum value. In the absence of a call to $SYSTEM.License.SetUserLimit(max) a Cache instance may consume all available license units.

Reqires access to the %Admin Manage resource.

classmethod TakeApplicationLicense(AppName As %String, FeatureKeyword As %String = "Concurrent Users", ByRef Count As %Integer, session As %CSP.Session) as %Status
$SYSTEM.License.TakeApplicationLicense(AppName,FeatureKeyword,.count,session)
Take (consume) a license unit for a named application and feature. The license feature value must be numeric in the loaded application license section. The Cache license user Id of the current process (or in the case of CSP, the session license Id) will be the user identifier associated with the application license consumed.

Arguments:

AppName: The 'Company.Application' value from the section name in cache.key for protected application license sections, or the name of the unprotected application license section loaded with LoadAppLicenseFile().

FeatureKeyword: The application keyword being consumed. If the FeatureKeyword is omitted, the default value is "Concurrent Users".

Count: ByRef argument to receive count of the number of times this user has now taken this application/keyword license.

session: The CSP session Id this application license should be taken for if the application license is being taken for a session, not the current process. If this argument is not present, a %session variable is defined and is a %CSP.Session object, then the application license will be taken for the %session object. If neither the session argument nor the %session variable is defined, the license is taken for the current process.

Return value: $$$OK, or error status.
An error status containing an INVALID ARGUMENT error will be returned if AppName is not licensed.
An error status, ERROR #5915: Cannot allocate a license, if the feature is not licensed or its capacity is exhausted.

An application license can be returned with the $SYSTEM.License.ReturnApplicationLicense(AppName, FeatureKeyword[[, .Count[, session]]) method. All application licenses taken for a process or a CSP session will be returned automatically when the process exits or the CSP session terminates.

Example: $SYSTEM.License.TakeApplicationLicense("MyCompany.MyApp","MyAppFeature",.NewCountTaken)
final classmethod Upgrade() as %String
Upgrade to a license (cache.key file) that has been copied to the mgr directory. In some cases the license key will not be upgraded or may be incompletely upgraded. Upgrades may not activate all additional license units if they are unable to allocate sufficient memory from the shared memory heap. Upgrades to a key with fewer license units will be deferred until the Cache instance is restarted. Upgrades to or from a "Power Unit" key will be deferred until the Cache instance is restarted.
Return value is 1 on success, "0|Reason for failure" on failure.
The failure message may refer you to cconsole.log for additional information.
classmethod UserNameLicensing(OnOffState As %Integer) as %Integer
Modify how the License User Identifier is specified. By default, the client IP address is used to identify a user to the Cache license tracking subsystem. If the Cache is installed with the normal security level, each process will be have a user identity ($username). The $SYSTEM.License.UserNameLicensing system method can be called to make the Cache license subsystem use $username as the license user identifier. The client IP address will be appended to $Username separated by an "@" sign to form the complete license identifier.

$SYSTEM.License.UserNameLicensing modifies the system state. It can be called from SYSTEM^%ZSTART to enable user name licensing at instance startup.

$SYSTEM.License.UserNameLicensing(1) enables $username based licensing and returns the previous state.
$SYSTEM.License.UserNameLicensing(0) disables $username based licensing and returns the previous state.
$SYSTEM.License.UserNameLicensing() returns the current state.

$SYSTEM.License.UserNameLicensing() returns an error if called with an argument with RealTime or Web Add-On keys because these license types use special login rules.
