Abstract
In a client-server computing system, where the server includes a storage device, a method is disclosed which is executed by the system for controlling and tracking client access to server software being executed by the system. The method includes initiating a first call from one or more clients to the server and instantiating a server component within a server application for each client call. The server components instantiate engine components, which log onto the storage device for assignment of session ID's. The session ID's are returned to the engine components and passed back to the server components and entered and attached to a shared persistent resource, thereafter breaking the link between each server component and each engine component. The session ID's are passed back to the respective client components for reference when a next call to the server is to be made and the link between each server component and each client component is broken. When a subsequent call is initiated from a client to the server, which includes a session ID, another server component is instantiated within the server application. The shared persistent resource is accessed and a request is made for the reference to the corresponding engine component, which provides access to the storage device and allows the server component to complete any work requested by the client. On completion of the work requested by each client, the link between the client and the server is broken.
