This does not include any vendor log files that have come into existence because of {{object|#.ExecutionUnit}} instances that are contained within this {{object}}.

Represents the vendor config files that have come into existence because of this {{object}}.

Each {{object|#.DeploymentUnit}} that is installed can have zero or more Execution Units. Once a Deployment Unit is installed it populates this table with its contained Execution Units. When the Deployment Unit (that caused this {{object}} to come into existence) is updated, this instance MAY be removed and new instances MAY come into existence. While the Deployment Unit (that caused this {{object}} to come into existence) is being updated, all {{object}} instances associated with the Deployment Unit will be stopped until the update is complete at which time they will be restored to the state that they were in before the update started. When the Deployment Unit (that caused this {{object}} to come into existence) is uninstalled, this instance is removed.

Execution Unit Identifier chosen by the {{object|#.ExecEnv}} during installation of the associated {{object|#.DeploymentUnit}}. The format of this value is Execution Environment specific, but it MUST be unique across {{object|#.ExecEnv}} instances.

This instance is currently running. This instance is in the process of Stopping and SHOULD transition to the {{enum|Idle}} state. If while running or transitioning between states this {{object}} identifies a fault this parameter embodies the problem. The value of {{enum|NoFault}} MUST be used when everything is working as intended. {{enum}} For fault codes not included in this list, the vendor MAY include vendor-specific values, which MUST use the format defined in {{bibref|TR-106|Section 3.3}}. If while running or transitioning between states this {{object}} identifies a fault this parameter provides a more detailed explanation of the problem. If {{param|ExecutionFaultCode}} has the value of {{enum|NoFault|ExecutionFaultCode}} then the value of this parameter MUST be {{empty}} and ignored by the Controller. If {{true}} and the {{param|RunLevel}} verification is also met, then this {{object}} will be automatically started by the device after its {{object|#.ExecEnv}} is either rebooted or restarted. If {{false}} this {{object}} will not be started after its {{object|#.ExecEnv}} is either rebooted or restarted until it is explicitly commanded to do so by either the Controller or another Execution Unit. Determines when this {{object}} will be started. If {{param|AutoStart}} is {{true}} and {{param|#.ExecEnv.{i}.CurrentRunLevel}} is greater than or equal to {{param}}, then this {{object}} will be started. If the value of {{param|#.ExecEnv.{i}.CurrentRunLevel}} is -1, then the associated {{object|#.ExecEnv.}} doesn't support Run Levels, thus the value of this parameter is irrelevant when read and setting its value has no impact to the Run Level of this {{object}}.

Represents the instances of multi-instanced objects that are directly controlled by, and have come into existence because of, this {{object}}. Represents the system processes that are active in the system because of this {{object}}. If {{param|Status}} is not {{enum|Active|Status}} it is expected that this list will be {{empty}}.

When the {{object|#.DeploymentUnit}} (that caused this {{object}} to come into existence) is uninstalled the vendor log files referenced here SHOULD be removed from the device.

Represents the application data volumes that are used by this {{object}}. Represents the {{object|#.ExecEnv}} that this {{object}} is associated with. {{numentries}} Configures the parameters of the auto-restart algorithm for this {{object|#}}. An auto-restart may be triggered if the Agent determines that the EU has terminated abnormally. An exponential backoff algorithm is applied (increasing each time the delay before the EU is re-launched) in order to prevent continual re-starting of the EU. The retry interval range is controlled by two Parameters, {{param|RetryMinimumWaitInterval}} and {{param|RetryIntervalMultiplier}}. Let ''m'' be the value of {{param|RetryMinimumWaitInterval}}, ''k'' the value of {{param|RetryIntervalMultiplier}}, and ''n'' the current value of {{param|RetryCount}}. Then on the next occasion that the Agent determines that the EU has terminated abnormally, the delay before re-starting the EU must lie between ''m * (k/1000)^n'' and ''m * (k/1000)^(n+1)'' seconds, so long as ''m * (k/1000)^n'' evaluates to a value less than {{param|RetryMaximumWaitInterval}}. Once this point has been reached, on all subsequent occasion that the Agent determines that the EU has terminated abnormally the delay before re-starting the EU must lie between {{param|RetryMaximumWaitInterval}}'' * (1000/k)'' and {{param|RetryMaximumWaitInterval}} seconds. Enable the auto-restart feature for this {{object|#}}. Configures the initial delay in {{units}} between detecting that the EU has terminated abnormally and re-starting it. Configures the maximum delay in {{units}} between detecting that the EU has terminated abnormally and re-starting it. Configures the retry interval multiplier. This value is expressed in units of 0.001, so for example a value of 2000 will result in the retry interval being doubled each time. Configures the maximum number of consecutive restarts (as shown in {{param|RetryCount}}) after which no more attempts will be performed. A value of zero means that the number of attempts is unlimited. If the {{object|#}} runs for this number of {{units}} without terminating abnormally the Agent MAY reset the {{param|RetryCount}} to zero, thereby resetting the exponential backoff algorithm. A value of zero disables this behavior. The number of restart attempts which have been initiated so far. Resetting this parameter to zero has the effect of re-initialising the exponential back-off algorithm. The time at which the {{object|#}} was last re-started. Initially this parameter is set to the Unknown Time (0001-01-01T00:00:00Z). The time at which the next restart of the {{object|#}} is scheduled to occur. The Infinte Time (9999-12-31T23:59:59Z) is used to indicate that no restart is currently scheduled. {{datatype|expand}} This object proposes a general location for vendor extensions specific to this Execution Unit, which allows multiple Execution Units to expose parameters without the concern of conflicting parameter names. These vendor extensions are related to displaying status and maintaining configuration for this Execution Unit.
