Abstract
Abstract A system, method and article of manufacture are provided for detecting an orphaned server context. A collection of outstanding server objects is maintained and a list of contexts is created for each of the outstanding server objects. A compilation of clients who are interested in each of the outstanding server objects are added to the list. Recorded on the list is a duration of time since the clients invoked a method accessing each of the contexts of the outstanding server objects. The list is examined at predetermined intervals for determining whether a predetermined amount of time has passed since each of the objects has been accessed. Contexts that have not been accessed in the predetermined amount of time are selected and information is sent to the clients identifying the contexts that have not been accessed in the predetermined amount of time.

Claim 9
Dependent Claim
170 words
A computer program embodied on a computer readable medium for detecting an orphaned server context, comprising: (a) a code segment that maintains a collection of outstanding server objects; (b) a code segment that creates a list of contexts for each of the outstanding server objects; (c) a code segment that adds to the list a compilation of clients who are interested in each of the outstanding server objects; (d) a code segment that records on the list a duration of time since the clients invoked a computer program accessing each of the contexts of the outstanding server objects; (e) a code segment that examines the list at predetermined intervals for determining whether a predetermined amount of time has passed since each of the objects has been accessed; (f) a code segment that selects contexts that have not been accessed in the predetermined amount of time; and (g) a code segment that sends information to the clients identifying the contexts that have not been accessed in the predetermined amount of time.
