Abstract

The present invention relates generally to computer systems, and more particularly relates to a method and system for automatically installing software applications in a computer environment. The installation of new software packages or upgrading of existing packages often requires a great deal of data to be transferred, copied, decompressed and installed, consuming valuable communication bandwidth, storage space and processing power. The invention greatly reduces the demand on system resources by: identifying the files desired to be downloaded and installed; sorting these identified files into parameter-specific and parameter-independent groups; and generating a separate package each of the separate groups of identified files. In this way, separate parameter-specific and parameter-independent software packages are generated, so only the necessary software packages need to be processed to install new software, or upgrade an existing software package.

Claims

1. A method of preparing files for downloading and installation, comprising the steps of:

identifying the files desired to be downloaded and installed;

sorting said identified files into parameter-specific and parameter-independent groups; and

generating a separate package each of said separate groups of said identified files,

whereby separate parameter-specific and parameter-independent packages are generated.

2. The method of claim 1, wherein said parameter comprises a specific platform.

3. The method of claim 1, wherein said parameter comprises a specific processor.

4. The method of claim 3, wherein said processor-independent package comprises a core package.

5. The method of claim 3, further comprising the steps of:

automatically detecting files made to execute on a particular processor; and

linking processor-specific and processor-independent files automatically.

6. The method of claim 1, wherein said parameter comprises a specific software application.

7. The method of claim 6, wherein said parameter comprises a specific version of a software application.

8. The method of claim 1, further comprising the step of:

identifying the parameter with respect to which said files are to be sorted into groups.

9. The method of claim 8, wherein said package includes a package manifest file (QPM file).

10. The method of claim 1, wherein said package includes a compressed package manifest and file (QPK file).

11. The method of claim 9, wherein said package includes a package repository (QPR file), said QPR file being a compressed QPM and QPK file.

12. The method of claim 2, further comprising the steps of:

automatically detecting files made to execute on a particular platform; and

linking platform-specific and platform-independent files automatically.

13. The method of claim 1, further comprising the step of:

responding to a manual request for dependency, by automatically determining the package from which the file originates and adding the dependency on that package, to the new package.

14. The method of claim 1, further comprising the steps of:

automatically identifying dependencies between packages; and

responding to the existence of a dependency by adding dependencies between packages.

15. The method of claim 8, further comprising the step of:

querying the end user to identify the parameter on which said step of sorting is based.

16. The method of claim 15, wherein said queries are either general or package specific.

17. The method of claim 15, comprising the step of allowing said end user to use responses to previous queries as a default template.

18. The method of claim 15, comprising the step of providing default responses to some questions as an option for said end user.

19. The method of claim 15, wherein said step of sorting comprises the steps of:

reading the file extension for each of said identified files; and

sorting said identified files by file extension.

20. The method of claim 15, wherein said step of sorting comprises the steps of:

reading the file header for each of said identified files; and

sorting said identified files by file header.

21. The method of claim 15, wherein said step of querying comprising the steps of:

issuing mandatory queries to said end user for certain parameters of the package; and

responding to the failure of said end user to provide responses to said mandatory queries, by abandoning the attempt to generate a package.

22. The method of claim 1, wherein said step of sorting comprises the step of sorting said identified files manually.

23. A method of preparing files for downloading and installation, comprising the steps of:

identifying the files desired to be downloaded and installed;

sorting said identified files into two or more groups, at least one of said groups of files containing files which are common to more than one application, and at least one of said groups of files containing files which are not common to more than one application; and

generating separate packages for said first and second groups of files.

24. A system for distributing software, comprising:

a personal computer;

a server; and

a communication network for interconnecting said personal computer;

a server;

wherein said server is operable to;

identify files to be downloaded and installed on said personal computer;

sort said identified files into separate groups by parameter-specific and parameter-independent groups; and

generate a separate package each of said separate groups of said identified files;

whereby said personal computer may download said identified files by downloading separate parameter-specific and parameter-independent packages.

25. An apparatus operable to perform the methods steps of:

identifying the files desired to be downloaded and installed;

sorting said identified files into separate groups by parameter-specific and parameter-independent groups; and

generating a separate package each of said separate groups of said identified files,

whereby separate parameter-specific and parameter-independent packages are generated.

26. A memory medium storing software code executable to perform the method of:

identifying the files desired to be downloaded and installed;

sorting said identified files into separate groups by parameter-specific and parameter-independent groups; and

generating a separate package each of said separate groups of said identified files,

whereby separate parameter-specific and parameter-independent packages are generated.
