摘要： A number of methods, apparatus, and data structures are disclosed for managing computer processes. In one aspect, a daemon process which manages server processes includes an active server table and a locator service. The locator service can look up and register server processes in the active server table. Furthermore, the locator service can start up server processes. In some embodiments, the locator service includes a look-up object and a server process registration object which perform the tasks of the locator service. In other embodiments, methods for managing server process such as starting and registering the server processes are taught. In one specific method, a daemon process performs a variety of steps in response to receiving a look-up call for a target object. These steps include obtaining a server identifier for the target object, determining the state of a server process, and returning addressing information corresponding to the server process under which the target object will activate. In related method aspects the daemon process will start the server process if it isn't running and/or wait until the server process is running to return the addressing information. In a separate method aspect, a server process self-starts; receiving an object reference for a desired target object, receiving a server process identification number, creating a communications port for itself, forming addressing information for itself, obtaining an object reference for a server process registration object, and registering itself by calling the server process registration object to invoke a register new process operation.
