A computer program product comprising at least one controller to enable a processor to perform incremental changes in storage and retrieval. The at least one controller comprises an incremental storage adaptor for enabling the processor to store a change associated with a base file, rather than modifying the base file by the change and storing the result as a new file. An incremental retrieval adaptor is included for enabling the processor to merge the change with the base file thereby forming a logical new file. The incremental retrieval adaptor can perform the merging in response to a call from an application running on the processor or another processor, and the incremental retrieval adaptor then provides or otherwise makes the logical new file available to the application.

System, method, and computer program product for providing an

A method, apparatus, and article of manufacture for displaying objects in an object-oriented system. A first view is graphically displayed on a monitor attached to a computer, wherein the first view displays one or more objects therein. A second view is also graphically displayed on the monitor attached to the computer, wherein a specified relationship is defined from the first view to the second view. When an action is performed in the first view it causes a modification to the second view in accordance with the specified relationship.

System, method, and computer program product for providing and

A method, apparatus, and article of manufacture which provides for synchronizing classes, objects, attributes, object properties, etc., in an object-oriented system. The method comprises the steps of identifying target classes, objects, attributes, object properties, etc., verifying whether the synchronization of each of the targets can proceed, and modifying the targets, wherein the target classes, objects, attributes, etc. are synchronized across the object-oriented system. The identifying step further comprises the steps of navigating the object-oriented system based on definitional relationships and ownership relationships, generating target identifiers that uniquely identify the targets, and recording the target identifiers in a linear data structure.

Method for synchronizing classes, objects, attributes and object

The present invention is a computer program product to avoid static variable initialization and reference conflicts in a multi-threaded computer system. There are four major problems that arise with computer programs containing static variable references and static variable initializations on a computer system with a multi-threaded operating system: (1) premature references made on an uninitialized static variable; (2) side effects caused by initialization competition among threads; (3) multiple initialization of the same static variable; and (4) server control of static variable reference and initialization. Each of these four problems is eliminated by the system and method of this invention. The invention operates by locking the CPU during identification of the first thread seeking to initiate a static variable operation, maintaining all other threads in a wait state, and unlocking the CPU thus releasing the waiting threads from their wait state. Another component of the invention provides an additional control mechanism to invoke the disclosed static variable controller to eliminate potential static variable conflicts among competing threads.

System and method for domained incremental changes storage and retrieval

A method for controlling access to a resource running on a host computer by one or more users which uses a timing policy to control when a current authorized user can be replaced by a new authorized user. The method comprises the steps of scanning a first list to verify that the new user is on the first list, scanning a second list to determine if a current user can be replaced without violating the timing policy, and granting the new user access to the resource if the timing policy is not violated. The method can be used to control access to an application program running on a file server in a local area network.
