Server Instance Behavior After Node Agent Failure

A node agent might be stopped unexpectedly, for example, by a software failure or other error. In this situation, any server instances that the node agent was managing are no longer managed. However, such server instances continue to run and remain accessible by the DAS. Information about the server instances can still be obtained through Enterprise Server administrative interfaces, and applications that are deployed on the server instances can still be accessed.

If the node agent is restarted, the server instances that are not managed remain unmamaged. The node agent does not resume the management of these server instances. If an unmanaged server instance is stopped unexpectedly, for example, by a software failure or other error, the node agent cannot restart the server instance.

If an unmanaged server instance must continue to run, you cannot resume the management of the server instance by a node agent. The only way to resume the management of an unmanaged server instance is to stop and restart the server instance after the node agent is restarted.
