問題文
A Managed Server that an administrator had started from a start script on the machine itself has failed, and Node Manager is running on that machine. What does Node Manager do about the failed instance, and where, if anywhere, is the ceiling on that behavior written down?
選択肢
- It leaves the instance alone, because it takes on the restart of an instance only where Node Manager itself brought that instance up, and the count of restarts it will try is capped by a property in its own startup settings file
- It asks the Administration Server whether the instance should come up again, because the decision rests with the domain, and the number of restarts is capped by the machine that the instance was assigned to
- It brings the instance up again once and then gives up, because a single attempt is all that it makes for an instance of any kind, and no setting anywhere raises that figure
- It brings the instance up again straight away, because it takes on the restart of every instance on its machine, and the number of restarts it will try is capped by an attribute of the server in the configuration of the domain, which the instance itself reads at each boot
