<p>A variety of methods and apparatus for managing deactivation and deletion of objects and server processes are taught. According to some embodiments of the present invention, a thread of execution termed the reaper thread systematically cycles through a computer process deactivating and/or deleting objects based upon a variety of criteria. One suitable criterion for object deactivation is based upon the amount of time lapsed since a client has requested services of the object. According to the timeout criterion, the reaper thread determines the period of time since the last client requested services from the object, compares this to a timeout value which may be defined by any suitable entity, and proceeds with deactivation and/or deletion accordingly. Object deletion may have a separate criterion or be specifically requested by a client. A deletion flag may be set to indicate that object deletion is requested. When an object has deactivated, the reaper thread further determines if the deletion flag for this object is set, and, if so, further proceeds to perform an object deletion operation. In some embodiments, the reaper thread is further responsible to shutdown the server process under which the reaper thread is executing. As is well known to those skilled in the art of object oriented programming, a thread of execution is essentially a sequential flow of the point of execution through a computer process. One suitable criterion for server process shutdown would be related to the server process activity.</p> |
