METHOD OF SYNCHRONIZING INDEPENDENTLY DISTRIBUTED SOFTWARE AND DATABASE SCHEMA

摘要

Upgrading a software application from one or more upgrade package files in a server (1) to a client (21a, 21b, 21c). According to this method a copy of the upgrade package files and an upgrade database table are created on the server (1). A pointer is created in the client's (21a, 21b, 21c) file on the server (1). This pointer points to the upgrade package files on the server (1). In invoking the upgrade, the upgrade files are made active, and the upgrade database table is scanned when a client (21a, 21b, 21c) docks. This is to determine the status of an upgrade with respect to the particular client (21a, 21b, 21c). The upgrade is copied to the client (21a, 21b, 21c) if the client (21a, 21b, 21c) has not received the upgrade. At this point the upgrade may be invoked at the client (21a, 21b, 21c). Also disclosed is a program product carrying code for the upgrade method.
