First Claim
1. A method for updating programs to be used in a network comprising a plurality of first type computers having a limited function range relative to a plurality of second type computers having a respective extended function range, a service being defined as comprising update services providing an updated facilities version to be performed by the second type computers to said first type computers, the method comprising the steps of:
- selecting a first subgroup comprising at least one first type computer;
selecting a second subgroup comprising at least one of the second type of computers for providing said updated facilities version exclusively to first type computers until a predetermined condition has occurred; and
loading at least one computer of the first subgroup with said updated facilities version during continued operation of the unselected plurality of first type computers with a former version means.

Abstract
The present invention relates to networked computer systems, and in particular to a method and system for improved update facilities for software programs installed on a subset of said networked computers. It is based on the concept that updating the supplier nodes and updating the dependent nodes have to be hierarchically separated from each other. The following sequence of steps is performed: selecting a first subgroup (20) comprising at least one dependent computer (24), selecting a second subgroup comprising at least one of the supplier computers (14) for providing the updated version means exclusively to dependent computers (24,26) until a predetermined condition has occurred, loading at least one computer (24) of the first subgroup (20) with an updated version means during continued operation of the unselected plurality of dependent computers (26,28,30) with a former version means.

15. A program product usable for updating programs to be used in a network comprising a plurality of first type computers having a limited function range relative to a plurality of second type computers having a respective extended function range, a service being defined as comprising update services providing an updated facilities version to be performed by the second type computers to said first type computers, said program product comprising:
a computer readable medium having recorded thereon computer readable program code means for performing the method comprising;
selecting a first subgroup comprising at least one first type computer;
selecting a second subgroup comprising at least one of the second type of computers for providing said updated facilities version exclusively to first type computers until a predetermined condition has occurred; and
loading at least one computer of the first subgroup with said updated facilities version during continued operation of the unselected plurality of first type computers with a former version means.
