Abstract

A method is described to enable a program update process to automatically apply only to those updates that are required by a user based on his current system level. Software updates for multiple licensed program products are packaged together on the same distribution media. Consequently, all of the updates since the last major release of each licensed program product have to be included. The update process needs to automatically apply only those updates that are required by a user based on his current system level. The reason for this is evident from the following real situation. Assume two different users, on System A and System B, and that both have the same licensed program product installed with the same major release number.

Method to Control Software-Update Applications

A method is described to enable a program update process to automatically apply only to those updates that are required by a user based on his current system level. Software updates for multiple licensed program products are packaged together on the same distribution media. Consequently, all of the updates since the last major release of each licensed program product have to be included. The update process needs to automatically apply only those updates that are required by a user based on his current system level. The reason for this is evident from the following real situation. Assume two different users, on System A and System B, and that both have the same licensed program product installed with the same major release number. The user on System A has previously acquired a software update diskette and applied updates for the product that change his product level from 1 to 2. The user on System B, however, has not applied any updates, so his product level is still 1. When they both receive the same update diskette that includes updates to change the product level to 3, the update process for the user on System A must apply only those updates that are required to change the product level from 2 to 3. However, for the user on System B, it must apply all the updates for this product. In accordance with the new method, update information for a licensed program product is packaged in different areas on the update media: 1. General update control information used to

determine which licensed program products have

updates that can be applied on a system.

2. Specific information...
