TerminateAppRequest

TerminateAppRequest Parameters

Attribute NameCardinalityData TypeDescriptionterminationType1Enum

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.

gracefulTerminationTimeout0..1IntegerThis 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

- None
