Abstract

The present invention provides a system and method of workstation configuration that includes a multi-level hierarchy management of preferences which are essentially managed and stored with a file server, rather than with each individual workstation. The invention comprises a computer network that includes workstations that have configurable hardware devices and software applications; a workstation server connected to the workstations that includes hierarchical preference files containing configuration information; and a preference manager for providing a coalesced, or merged, set of configuration parameters to the workstations based on the information in the hierarchical preference files.

9. The computer network of claim 1 wherein said preference files include manufacturer preference files, installation preference files, terminal specific preference files, group preference files and user preference files.

10. The computer network of claim 1 wherein each of said workstations include an interface system that causes the workstation to be configured in a predetermined manner when the workstation receives said coalesced set of configuration parameters.

a coalescing mechanism that receives a plurality of configuration parameters from each of said selected preference files and that applies said configuration parameters to said networked workstation, said coalescing mechanism being executable on said networked workstation.

14. The program product of claim 13 wherein said plurality of preference files are stored in a plurality of hierarchy levels.

15. The program product of claim 14 wherein said plurality of hierarchy levels include a manufacturer level.

16. The program product of claim 14 wherein said plurality of hierarchy levels include an installation level.

17. The program product of claim 14 wherein said plurality of hierarchy levels include a group user level.

18. The program product of claim 14 wherein said plurality of hierarchy levels include a user level.

19. The program product of claim 14 wherein said plurality of hierarchy levels include a terminal specific level.

20. The program product computer network of claim 13 wherein said selection mechanism includes a mechanism that receives at least one identifier as input criteria for selecting preference files.

21. The program product of claim 20 wherein said at least one identifier is a user id.

22. The program product of claim 21 wherein said at least one identifier is a workstation identifier.

23. The program product of claim 21 wherein said at least one identifier includes time and date information.

24. The program product of claim 21 wherein said at least one identifier includes information containing a physical location of said workstation.

25. The program product of claim 20 wherein said coalescing mechanism includes a mechanism that resolves a pair of conflicting parameters by applying the most recently received parameter and canceling the earlier received parameter.

26. The program product computer network of claim 20 wherein said coalescing mechanism includes a mechanism that blocks sequentially applied configuration parameters.

27. The program product of claim 13 wherein configuration preferences include hardware preferences.

28. The program product of claim 13 wherein configuration preferences include software application preferences.

29. The program product computer network of claim 13 wherein each of said networked workstations includes an interface system that causes the workstation to be configured in a predetermined manner when the received configuration parameters are applied.

30. A method for managing preferences for a client computer in a network, comprising:

selecting a preference file from a plurality of preference files stored on a file server, wherein said plurality of preference files contain configuration parameters for client computers in the network;
