The ApplicationSystem class represents an application or a software system that supports a particular business function and that can be managed as an independent unit. Such a system can be decomposed into its functional components using the CIM_SoftwareFeature class. The Features for a particular application or software system are located using the CIM_ApplicationSystemSoftwareFeature association. The features are part of the deployment-oriented aspects of the application system. With regard to the application runtime aspects, the ApplicationSystem class also represents the core class of the Application Systems' sub-model which of the application runtime model. Its role in the systems sub-model is a) the root node of the containment hierarchy of the application elements (at runtime) as services, components, sub-systems, etc., b) the place for runtime overview information such as response time or system status, c) runtime control of the entire application (e.g., start/stop), and d) the main entry point to the navigation through and drill-down into the runtime model. The lifetime of an instance of this class is not limited to the application instance it represents. Even if the application is not running, the ApplicationSystem object can report properties that have values (e.g., the name of the application or the current status). Note that it is also possible to define the lifetime of the objects through the lifetime of the application instances. Through ApplicationSystemDependency, non-containment relationships can be expressed. | Qualifiers:Version ( "2.8.0" ) UMLPackagePath ( "CIM::Application::DeploymentModel" ) | Parameters (local in grey) | | ValueMap { "0" , "1" , "2" , "3" , "4..4096" , "4097..32767" , "32768..65535" } Values { "Unspecified Error" , "Completed with No Error" , "Start Already in Progress" , "Failed" , "DMTF Reserved" , "Method Reserved" , "Vendor Specific" } ModelCorrespondence { "CIM_ApplicationSystem.EnabledState" , "CIM_ApplicationSystem.RequestedState" } uint16StartApplication() StartApplication() starts an application system. The ApplicationSystem object must have been created prior to the invocation of this method. It is up to the implementation of the method to define which of the contained or dependent sub-elements are to be started and in which order their startup may occur. Since a system startup can extend over long periods of time (several minutes is not unusual for complex distributed applications), the method can be implemented synchronously or asynchronously. In both cases EnabledState and RequestedState reflect the current state of the application and the desired state (Enabled) respectively. The exact nature of the errors during the startup cannot be determined in the asynchronous case. The method must return one of the following values: Unspecified Error: If no return code can be identified Completed with No Error: successful invocation Start Already in Progress: application still being started Failed:Indicates errors upon execution. | ValueMap { "0" , "1" , "2" , "3..32767" , "32768..65535" } Values { "Unknown" , "Distributed" , "Local" , "DMTF Reserved" , "Vendor Specific" } uint16 Distribution ; Distribution describes how the application system is distributed with respect to its underlying servers. In general, the application system is distributed or local. This property indicates whether the application system is running on one or multiple servers. This can be determined without having to query for associated servers represented by ComputerSystems. Distributed systems also introduce a virtual notion to themselves. Note that a distributed application system is not tangible but virtual. Only its contained local systems can be found as processes or threads, and can therefore be regarded as tangible. The distributed system remains a named, virtual entity, that scopes strongly bound constituents and allows the application to be managed in its entirety. The property is needed to help root cause analysis and operations, especially when these are automated, in order to clearly know that more than one executed application - most likely the local application systems - is affected by the management task. This is particularly true if the contained application systems provide uniform functionality like webserver or application server farms. To express constraints between distributed and local system, this class must be derived and appropriate associations must be defined. This property should not be confused with the Roles[] property defined in System. The latter is reserved for administrator assigned roles. | ValueMap { "0" , "1" , "2" , "5..4096" , "4097..65535" } Values { "Unknown" , "Serving" , "Not Serving" , "DMTF Reserved" , "Vendor Specific" } ModelCorrespondence { "CIM_ManagedSystemElement.OperationalStatus" } uint16 ServingStatus ; ServingStatus is a summary of MSE.OperationalStatus. It allows simplified and efficient determination of whether the application is providing service or has stopped doing so for various reasons like errors, shutdown, abort, etc. Therefore, no transitional values are provided. The property does not show any errors. Errors MUST be described in MSE.OperationalStatus, and MAY also be described in logs or other data sources. Therefore, ServingStatus is suited to provide summary information for monitoring purposes and service level management. The mapping to MSE.OperationalStatus is as follows: ServingStatus <- MSE.OperationalStatus Unknown <- Unknown, No Contact, Lost Communication Either of the values <- Other Serving <- OK, Degraded, Stressed, Predictive Failure, Completed Not Serving <- Error, Non-Recoverable Error, Starting, Stopping, Stopped, In Service, Aborted, Dormant, Supporting Entity in Error. | ValueMap { "0" , "1" , "2" , "3" , "4..4096" , "4097..32767" , "32768..65535" } Values { "Unspecified Error" , "Completed with No Error" , "Stop Already in Process" , "Failed" , "DMTF Reserved" , "Method Reserved" , "Vendor Specific" } ModelCorrespondence { "CIM_ApplicationSystem.EnabledState" , "CIM_ApplicationSystem.RequestedState" } uint16StopApplication() StopApplication() allows for stopping/shutting down an application system. It is up to the implementation of the method to define which of the contained or dependent sub-elements are to be stopped and in which order their stop has to occur. Since a system shutdown can last considerable time (several minutes is not necessarily unusual for complex distributed applications), the method can be implemented synchronously or asynchronously. In both cases EnabledState and RequestedState reflect the current state of the application and the desired state (Disabled) respectively. The exact nature of the errors during the stop cannot be determined in the asynchronous case. The method must return one of the following: Unspecified Error: If no return code can be identified Completed with No Error: successful invocation Stop Already in Process: application is shutting down Failed: Indicates errors upon execution. | datetime StartupTime ; The point in time (date and time) when the application system was last started. If the application system is in a state other the state Enabled (i.e., started and running) this value is not meaningful and the property value MUST be set to all zeros. StartupTime is preferably the point in time when the application is available to the user. Instead, if the provider and/or the instrumentation cannot determine the point in time the application becomes available, the point in time can be used at which the underlying operating system reports successful launch of the application. If no value can be provided the property value MUST be set to all zeros. | ValueMap { "0" , "2" , "3" , "4" , "10" , "11..32767" , "32768..65535" } Values { "Unknown" , "Enabled" , "Disabled" , "Shutting Down" , "Starting" , "DMTF Reserved" , "Vendor Reserved" } Override ( "EnabledState" ) uint16 EnabledState = 0 ; EnabledState is an integer enumeration that indicates the enabled/disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down and starting are transient states between enabled and disabled. In contrast to the original version defined higher in the inheritance hierarchy (EnabledLogicalElement), EnabledState is simplified. It reflects the notion of an execution status tailored to applications and represents a summary of the original property. It allows simplified and efficient determination of whether the application is started, stopped or in transition between either of these states. The property does not show any errors. Errors MUST be described in MSE.OperationalStatus, and MAY also be described in logs or other data sources. The mapping to MSE.OperationalStatus is as follows: ExecutionStatus <- MSE.OperationalStatus Unknown <- Unknown, No Contact, Lost Communication, Either of the values <- Other Enabled (started) <- OK, Degraded, Stressed, Predictive Failure, In Service, Dormant, Supporting Entity in Error, Completed Enabled or Disabled (Started or Stopped) <- Error, Non-Recoverable Error Starting <- Starting Shutting Down (Stopping) <- Stopping Disabled (Stopped) <- Stopped, Aborted. The mapping to the original EnabledState property is as follows: Unknown <- Unknown, Not Applicable Either of the values <-Other Enabled <- Enabled, Enabled but Offline, In Test, Deferred, Quiesce Disabled <- Disabled ShuttingDown <- ShuttingDown Starting <- Starting. | ModelCorrespondence { "CIM_ApplicationSystem.ServingStatus" } datetime LastServingStatusUpdate ; The point in time at which the ServingStatus property was last updated. | ArrayType ( "Indexed" ) ModelCorrespondence { "CIM_System.OtherIdentifyingInfo" } string IdentifyingDescriptions [ ] ; An array of free-form strings providing explanations and details behind the entries in the OtherIdentifying Info array. Note, each entry of this array is related to the entry in OtherIdentifyingInfo that is located at the same index. | Write string Roles [ ] ; An array (bag) of strings that specifies the administrator -defined roles this System plays in the managed environment. Examples might be 'Building 8 print server' or 'Boise user directories'. A single system may perform multiple roles. Note that the instrumentation view of the 'roles' of a System is defined by instantiating a specific subclass of System, or by properties in a subclass, or both. For example, the purpose of a ComputerSystem is defined using the Dedicated and OtherDedicatedDescription properties. | MaxLen ( 64 ) MappingStrings { "MIF.DMTF|General Information|001.3" } Write string PrimaryOwnerName ; The name of the primary system owner. The system owner is the primary user of the system. | MaxLen ( 64 ) string NameFormat ; The System object and its derivatives are top-level objects of CIM. They provide the scope for numerous components. Having unique System keys is required. A heuristic can be defined in individual System subclasses to attempt to always generate the same System Name Key. The NameFormat property identifies how the System name was generated, using the heuristic of the subclass. | ArrayType ( "Indexed" ) MaxLen ( 256 ) ModelCorrespondence { "CIM_System.IdentifyingDescriptions" } string OtherIdentifyingInfo [ ] ; OtherIdentifyingInfo captures additional data, beyond System Name information, that could be used to identify a ComputerSystem. One example would be to hold the Fibre Channel World-Wide Name (WWN) of a node. Note that if only the Fibre Channel name is available and is unique (able to be used as the System key), then this property would be NULL and the WWN would become the System key, its data placed in the Name property. | MaxLen ( 256 ) Key Override ( "Name" ) string Name ; The inherited Name serves as the key of a System instance in an enterprise environment. | MaxLen ( 256 ) Key string CreationClassName ; CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified. | MaxLen ( 256 ) MappingStrings { "MIF.DMTF|General Information|001.4" } Write string PrimaryOwnerContact ; A string that provides information on how the primary system owner can be reached (for example, phone number, e-mail address, and so on). | datetime TimeOfLastStateChange ; The date or time when the EnabledState of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated. | ModelCorrespondence { "CIM_EnabledLogicalElement.EnabledState" } string OtherEnabledState ; A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ('Other').

When the requested state change takes place, the EnabledState and RequestedState of the element will be the same. Invoking the RequestStateChange method multiple times could result in earlier requests being overwritten or lost. If 0 is returned, then the task completed successfully and the use of ConcreteJob was not required. If 4096 (0x1000) is returned, then the task will take some time to complete, ConcreteJob will be created, and its reference returned in the output parameter Job. Any other return code indicates an error condition. | ValueMap { "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" , "10" , "11" , "12" , ".." , "32768..65535" } Values { "Enabled" , "Disabled" , "Shut Down" , "No Change" , "Offline" , "Test" , "Deferred" , "Quiesce" , "Reboot" , "Reset" , "Not Applicable" , "DMTF Reserved" , "Vendor Reserved" } ModelCorrespondence { "CIM_EnabledLogicalElement.EnabledState" } uint16 RequestedState = 12 ; RequestedState is an integer enumeration that indicates the last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ('Not Applicable'), then this property has no meaning. By default, the RequestedState of the element is 5 ('No Change'). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. Offline (6) indicates that the element has been requested to transition to the Enabled but Offline EnabledState. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are 'Reboot' (10) and 'Reset' (11). Reboot refers to doing a 'Shut Down' and then moving to an 'Enabled' state. Reset indicates that the element is first 'Disabled' and then 'Enabled'. The distinction between requesting 'Shut Down' and 'Disabled' should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. A particular instance of EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ('Not Applicable') is used. | ValueMap { "0" , "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" , "10" , "11" , "12" , "13" , "14" , "15" , "16" , "17" , "18" , ".." , "0x8000.." } ArrayType ( "Indexed" ) Values { "Unknown" , "Other" , "OK" , "Degraded" , "Stressed" , "Predictive Failure" , "Error" , "Non-Recoverable Error" , "Starting" , "Stopping" , "Stopped" , "In Service" , "No Contact" , "Lost Communication" , "Aborted" , "Dormant" , "Supporting Entity in Error" , "Completed" , "Power Mode" , "DMTF Reserved" , "Vendor Reserved" } ModelCorrespondence { "CIM_ManagedSystemElement.StatusDescriptions" } uint16 OperationalStatus [ ] ; Indicates the current statuses of the element. Various operational statuses are defined. Many of the enumeration's values are self-explanatory. However, a few are not and are described here in more detail. 'Stressed' indicates that the element is functioning, but needs attention. Examples of 'Stressed' states are overload, overheated, and so on. 'Predictive Failure' indicates that an element is functioning nominally but predicting a failure in the near future. 'In Service' describes an element being configured, maintained, cleaned, or otherwise administered. 'No Contact' indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it. 'Lost Communication' indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable. 'Stopped' and 'Aborted' are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the state and configuration of the element might need to be updated. 'Dormant' indicates that the element is inactive or quiesced. 'Supporting Entity in Error' indicates that this element might be 'OK' but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower-layer networking problems. 'Completed' indicates that the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error). 'Power Mode' indicates that the element has additional power model information contained in the Associated PowerManagementService association. OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today's environment to the future. This change was not made earlier because it required the deprecated qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly recommended that providers or instrumentation provide both the Status and OperationalStatus properties. Further, the first value of OperationalStatus should contain the primary status for the element. When instrumented, Status (because it is single-valued) should also provide the primary status of the element. | ArrayType ( "Indexed" ) ModelCorrespondence { "CIM_ManagedSystemElement.OperationalStatus" } string StatusDescriptions [ ] ; Strings describing the various OperationalStatus array values. For example, if 'Stopping' is the value assigned to OperationalStatus, then this property may contain an explanation as to why an object is being stopped. Note that entries in this array are correlated with those at the same array index in OperationalStatus. | ValueMap { "OK" , "Error" , "Degraded" , "Unknown" , "Pred Fail" , "Starting" , "Stopping" , "Service" , "Stressed" , "NonRecover" , "No Contact" , "Lost Comm" , "Stopped" } MaxLen ( 10 ) Deprecated { "CIM_ManagedSystemElement.OperationalStatus" } string Status ; A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for 3 reasons: 1) Status is more correctly defined as an array. This definition overcomes the limitation of describing status using a single value, when it is really a multi-valued property (for example, an element might be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus. | MappingStrings { "MIF.DMTF|ComponentID|001.5" } datetime InstallDate ; A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed. | ValueMap { "0" , "5" , "10" , "15" , "20" , "25" , "30" , ".." } Values { "Unknown" , "OK" , "Degraded/Warning" , "Minor failure" , "Major failure" , "Critical failure" , "Non-recoverable error" , "DMTF Reserved" } uint16 HealthState ; Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. The following continuum is defined: 'Non-recoverable Error' (30) - The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost. 'Critical Failure' (25) - The element is non-functional and recovery might not be possible. 'Major Failure' (20) - The element is failing. It is possible that some or all of the functionality of this component is degraded or not working. 'Minor Failure' (15) - All functionality is available but some might be degraded. 'Degraded/Warning' (10) - The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors. 'OK' (5) - The element is fully functional and is operating within normal operational parameters and without error. 'Unknown' (0) - The implementation cannot report on HealthState at this time. DMTF has reserved the unused portion of the continuum for additional HealthStates in the future. | string ElementName ; A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. | MaxLen ( 64 ) string Caption ; The Caption property is a short textual description (one- line string) of the object. | string Description ; The Description property provides a textual description of the object. |
