ABSTRACT:
A method and apparatus for controlling server activation. In the prior art, there exists a race condition between the shutting down of an old server and the starting up of a new server. Further, rapidly restarting servers, such as daemonic servers, are prone to thrashing behavior. However, an embodiment of the invention avoids this undesired behavior by providing an additional "shutting down" state in the server finite state machine running in the ORB daemon. This additional state allows an old server to complete the necessary shut down procedures prior to the startup of a new server. Also, a process is provided for handling servers that are too slow to shut down or start up. A second additional state is provided in the server finite state machine to handle self started servers.
