| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| Description | string | |
| Description | string | Since UnitOfWork is designed to be an extremely lightweight object, it is recommended that this property not be used. The Description specified for the instance's associated CIM_UnitOfWorkDefintion should apply. |
| Override | string | Description |
| ElapsedTime | datetime | |
| Description | string | The elapsed time since the UnitOfWork was started. Upon completion of the UnitOfWork, this property contains the total amount of time taken in processing the entire UnitOfWork. |
| Id | sint64 | |
| Description | string | The identifier of the UnitOfWork, within the context of the UnitOfWorkDefinition. |
| Key | boolean | true |
| MutualContextId | string | |
| Description | string | A string that uniquely identifies the mutual context of UnitOfWork instances. The context is defined as an individual action that several UnitOfWork instances participate in. The use of Ids such as OSF UUID/GUIDs is recommended, although some implementations may require longer Ids. (This is the reason why no maxlen(16) qualifier has been used.)
MutualContextId explicitly identifies the context for instances of UnitOfWork, that is otherwise provided implicitly by SubUoW association instances. In addition, one can query directly (i.e. without following the associations) for UnitOfWork instances that participate in some individual action (i.e., the mutual context). If no mutual context is needed or if it is not supported by the implementation, the value is NULL.
Note that the MutualContextId value is to be transferred internally between the participating UnitOfWork implementations such that each UnitOfWork instance implementation receives its value from its predecessor/parent or initially creates the value if it is the first instance of the context. |
| StartTime | datetime | |
| Description | string | The time that the UnitOfWork was started. |
| Status | uint16 | |
| Description | string | An enumeration identifing the status of the UnitOfWork. Most of the property values are self-explanatory, but a few need additional text:
3="Completed" - Should be used to represent a 'completed' transaction whose status ('good', 'failed' or 'aborted') is unknown.
6="Completed Aborted" - Should be used when a UnitOfWork has completed but was not allowed to end normally. An example would be when the Stop or Back buttons are selected from a web browser, before a page is fully loaded. |
| ValueMap | string | 1, 2, 3, 4, 5, 6 |
| Values | string | Active, Suspended, Completed, Completed Good, Completed Failed, Completed Aborted |
| TraceLevel | uint32 | |
| Description | string | Indicates the granularity at which traces are written for this particular instance of UnitOfWork. Traces allow providing more detailed information on the course of the execution of the UnitOfWork than just the status and the elapsed time. The trace level does not indicate where the traces are found (i.e. in which file or CIM instances). TraceLevel cannot be set (i.e. written) since an instance of UnitOfWork only publishes information. So, the application code that executes the unit of work must receive the desired trace level by its caller (e.g. the parent module, the user or some remote system that initiates the unit of work).
If its value is 0, no traces are available. If its value is > 0, traces are available. Except 0, the possible values and their semantics are implementation dependent. Two instances of UnitOfWork (even with the same definition) may have different trace levels since the desired or required granularity of traces may be dependent on the execution context (detection of an error, analysis of an error, etc.) of the unit of work.
The trace level can be encoded as a bit map (each individual bit indicates a certain trace type and/or level of detail) or numbers (that are further defined by a value map). No encoding scheme is imposed since no general rules or standards exist and in consequence, application developers could reuse their existing trace level scheme. |
| UoWDefId | string | |
| Description | string | A 16 byte value that uniquely identifies the UnitOfWork Definition. The use of OSF UUID/GUIDs is recommended. |
| Key | boolean | true |
| MaxLen | uint32 | 16 |
| Propagated | string | CIM_UnitOfWorkDefinition.Id |
| UserName | string | |
| Description | string | The name of the user who initiated the UnitOfWork. This may be a real user's login name or a logical name representing an application. |
