Abstract
A method, suitable for use in client/server system, which allows multiple copies of a single-user application to run simultaneously in a multi-user operating system without modification of the single-user program, by modifying existing operating system methods used for object name creation, look-up, and deletion. The method creates a user global context by labeling each instance of the single-user application with a user identifier (name) that defines a single-user name space in which each labeled object is only available to the named user. In addition, the single-user server process is allowed to impersonate the client for allowing the server to access the named resources of the single-user name space. A coexisting system global context is also created by marking system global named resources.
