TerminateAppRequest
TerminateAppRequest

TerminateAppRequest Parameters
Attribute Name	Cardinality	Data Type	Description
terminationType	1	Enum	Indicates whether forceful or graceful termination is requested. See note. • FORCEFUL: it will shut down the application instance and release the resources immediately after accepting the request. See note. • GRACEFUL: it will first arrange to take the application instance out of service after accepting the request. Once the operation of taking the application instance out of service finishes or once the timer value specified in the "gracefulTerminationTimeout" attribute expires, it will shut down the application instance and release the resources.
gracefulTerminationTimeout	0..1	Integer	This attribute is only applicable in case of graceful termination. It defines the time to wait for the application instance to be taken out of service before shutting down the application and releasing the resources. The unit is seconds. If not given and the "terminationType" attribute is set to "GRACEFUL", it is expected to wait for the successful taking out of service of the application, no matter how long it takes, before shutting down the application and releasing the resources.

"Bandwidth Management".
version	1	String	Version of the Service
state	1	ServiceState	Contains the service state.
transportId	0..1	String	Identifier of the platform-provided transport to be used by the service. Valid identifiers may be obtained using the "Transport information query" procedure.
