Abstract

The present invention provides a method of configuring a package that enables the reduction of load on a network without a temporary need for a large recording area on the client side when reconfiguring a software package from given components. A second computer receives, from a first computer, combination information on a combination of one or more components and position information indicating storage locations of components recorded in the first computer, receives a selection of given components from a user, determines the combination of the components selected based on the combination information, receives the selected components based on the determination of the combination and the position information corresponding to the selected components, and configures the secondary software package using the received components.

Claims

1. A package configuration method of configuring a secondary software package performed in a second computer by receiving one or more components of a primary software package recorded in a first computer, the method causing the second computer:

receive, from the first computer, combination information on a combination of the one or more components and position information for indicating physical storage locations of the components recorded in the first computer;

receive a selection of a part or all of the one or more components from a user;

determine a combination of the components selected based on the combination information;

request the selected components from the first computer based on the determination of the combination and the position information corresponding to the selected components;

receive, on the second computer, the selected components based on the position information corresponding to the selected components;

configure, on the second computer, the secondary software package using the received components;

delete, from the second computer, the position information indicating the physical storage locations of the components recorded in the first computer;

create new position information for indicating physical storage locations of the components of the secondary software package recorded in the second computer; and

provide one or more components of the secondary software package to a third computer, the providing including providing the new position information to the third computer.

2. The method according to claim 1, wherein the configuring of the secondary software package includes configuring the secondary software package by using the received components, the combination information on the combination of the received components, and the position information indicating the storage locations of the received components.

3. The method according to claim 1, wherein the secondary software package is configured in the second computer by receiving one or more components of the primary software package recorded in the first computer, and a tertiary software package is configured in the third computer by receiving the one or more components of the secondary software package recorded in the second computer, and the providing allows the third computer to:

receive, from the second computer, combination information on a combination of the components and the new position information for indicating the storage locations of the components recorded in the second computer;

receive a selection of a part or all of the one or more components from a user;

determine a combination of the components selected based on the combination information;

request the selected components from the second computer based on the determination of the combination and the position information corresponding to the selected components;

receive the selected components; and

configure the tertiary software package using the received components.

4. The method according to claim 3, wherein the configuring of the tertiary software package includes configuring a package using the combination information, the new position information, and the received components.

5. The method according to claim 1, further comprising appending digital signatures to each of the one or more components and verifying the components received on the second computer by way of the digital signatures.

6. The method according to claim 1, further comprising appending a digital signature to the combination information and verifying the received combination information by way of the digital signature.

7. The method according to claim 1, further comprising appending a digital signature to the entire package that has been configured.

8. The method according to claim 1, further comprising:

allowing the third computer to;

receive, on the third computer, the one or more components of the secondary software package based on the new position information corresponding to the one or more components.

9. The method according to claim 8, further comprising:

deleting, from the third computer, the new position information indicating the physical storage locations of the components recorded in the second computer; and

creating further new position information for indicating physical storage locations of the components of a tertiary software package recorded in the third computer.
