Abstract

A system and method for updating an update module. A pair-update module is executed to update software on a processing system. The pair-update module includes an installation updater and a bootstrap updater. The installation updater applies installation updates to installation files of the processing system, while the bootstrap updater applies bootstrap updates to the installation updater.

Claims

1. A method, comprising:

executing a pair-update module of a processing system to update software of the processing system, the pair-update module including an installation updater and a bootstrap updater, the installation updater to apply installation updates to installation files of the processing system and the bootstrap updater to apply bootstrap updates to the installation updater; and

applying the bootstrap updates to the installation updater.

2. The method of claim 1, further comprising:

querying an update repository to determine whether the bootstrap updates are available for the processing system; and

if the bootstrap updates are available, then retrieving the bootstrap updates from the update repository.

3. The method of claim 2, further comprising generating a bootstrap script to instruct the bootstrap updater how to apply the bootstrap updates to the installation updater.

4. The method of claim 3, wherein applying the bootstrap updates to the installation updater comprises:

terminating the installation updater after retrieving the bootstrap updates to release the installation updater for applying the bootstrap updates to the installation updater;

loading the bootstrap updater; and

executing the bootstrap script to apply the bootstrap updates to the installation updater.

5. The method of claim 1, further comprising:

querying the update repository to determine whether the installation updates and the bootstrap updates are available for the processing system; and

if the installation updates and the bootstrap updates are available, then retrieving the installation updates and the bootstrap updates from the update repository.

6. The method of claim 5, further comprising applying the installation updates to the installation files, and wherein applying the bootstrap updates to the installation updater comprises applying the bootstrap updates to the installation updater after the installation updates have been applied to the installation files and the installation updater terminated.

7. The method of claim 1, wherein the processing system comprises a server node of an enterprise system and wherein the installation files comprise a Web Application Server.

8. The method of claim 7, wherein the Web Application Server is based on one of a .NET framework and a Java Enterprise framework.

9. A machine-accessible medium that provides instructions that, if executed by a machine, will cause the machine to perform operations comprising:

executing a pair-update module including an installation updater and a bootstrap updater to update software of the machine;

updating installation files of the machine by the installation updater; and

updating the installation updater of the machine by the bootstrap updater.

10. The machine-accessible medium of claim 9, further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

querying an update repository to determine whether at least one of installation updates and bootstrap updates are available for the machine; and

if at least one of the installation updates and the bootstrap updates are available, then retrieving the at least one of the installation updates and the bootstrap updates from the update repository.

11. The machine-accessible medium of claim 10, wherein updating the installation files comprises applying the installation updates to the installation files and wherein updating the installation updater comprises applying the bootstrap updates to the installation updater.

12. The machine-accessible medium of claim 11, further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

generating a bootstrap script to instruct the bootstrap updater to apply the bootstrap updates to the installation updater.

13. The machine-accessible medium of claim 12, wherein applying the bootstrap updates to the installation updater comprises:

terminating the installation updater after retrieving the at least one of the installation updates and the bootstrap updates to release the installation updater for applying the bootstrap updates to the installation updater;

loading the bootstrap updater; and

executing the bootstrap script to apply the bootstrap updates to the installation updater.

14. The machine-accessible medium of claim 9, wherein the machine comprises a server node of an enterprise system and wherein the installation files comprise a Web Application Server.

15. The machine-accessible medium of claim 14, wherein the Web Application Server is based on one of a .NET framework and a Java Enterprise framework.

16. A system, comprising:

a database having stored therein a bootstrap update; and

a server node communicatively coupled to the database, the server node comprising a processor and logic executable by the processor to;

execute a pair-update module to update software of the server node, the pair-update module including an installation updater and a bootstrap updater, the installation updater to update installation files of the server node and the bootstrap updater to update the installation updater;

retrieve bootstrap updates from the database; and

update the installation updater with the bootstrap updates.

17. The system of claim 16, wherein the database further having stored therein installation updates, and further comprising logic executable by the processor to:

retrieve the installation updates from the database; and

update the installation files with the installation updates.

18. The system of claim 17, wherein the server node further comprises logic executable by the processor to:

query the database to determine whether the installation updates and the bootstrap updates are available prior to retrieving the bootstrap updates and the installation updates.

19. The system of claim 18, wherein the server node further comprises logic executable by the processor to:

generate a bootstrap script to instruct the bootstrap updater to apply the bootstrap updates to the installation updater.

20. The system of claim 19, wherein the logic to apply the bootstrap updates to the installation updater comprises logic executable by the processor to:

terminate the installation updater after transferring the bootstrap updates and the installation updates to release the installation updater to apply the bootstrap updates to the installation updater;

load the bootstrap updater; and

execute the bootstrap script to apply the bootstrap updates to the installation updater.

21. The system of claim 16, wherein the server node comprises a Web Application Server node of an enterprise system.

22. The system of claim 21, wherein the Web Application Server node is based on one of a .NET framework and a Java Enterprise framework.

23. A system, comprising:

means for retrieving installation updates and bootstrap updates from an update repository;

installation updater means for updating installation files of a server node with the installation updates; and

bootstrap updater means for updating the installation updater means.

24. The system of claim 23, further comprising:

means for querying the update repository to determine whether the installation updates and the bootstrap updates are available.

25. The system of claim 24, further comprising:

means for generating a bootstrap script to instruct the bootstrap updater means how to apply the bootstrap updates to the installation updater means after the installation updater means has been terminated.

26. The system of claim 24 wherein the installation updater means also comprises the means for retrieving and the means for querying.

27. The system of claim 25 wherein the installation updater means also comprises the means for generating.
