Abstract

Successor versions of an application service provision runtime library of an application service provision apparatus are provided with corresponding update services to facilitate upgrade of applications to selected ones of the successor versions on request. In various embodiments, a dispatcher of the application service provision apparatus is provided with complementary functions to coordinate the servicing of the upgrade requests. In some embodiments, each of the update services is equipped to upgrade the application from an immediate predecessor version of the runtime library. In other embodiments, each of the update services is equipped to upgrade the application from any predecessor version of the runtime library.

said third update service of said immediate successor version upgrading said application to said immediate successor version of the first version of the runtime library; and

said third update service of said immediate successor version notifying said dispatcher of completion upon upgrading said application to said immediate successor version of the first version of the runtime library.

6. The method of claim 4, wherein said second later version of the runtime library is greater than one generation removed from said first version of the runtime library, and said method further comprises:

said dispatcher notifying a third update service of an immediate predecessor version of said second version of the runtime library of said request;

said third update service of said immediate predecessor version upgrading said application to said immediate predecessor version of the second version of the runtime library; and

said third update service of said immediate predecessor version notifying said dispatcher of completion upon upgrading said application to said immediate predecessor version of the second version of the runtime library.

7. The method of claim 4, wherein said second later version of the runtime library is a successor version of greater than one generation removed from said first version of the runtime library, said dispatcher notifying said second update service of said second version of said application service provision runtime library of said request directly, and said second update service upgrading said application to said second version of the runtime library.

8. An apparatus comprising:

storage medium having stored therein programming instructions designed to implement a dispatcher on the apparatus to

receive notification, from a first update service of a first version of an application service provision runtime library, of an application requesting update to a second later version of the application service provision runtime library, and

notify a second update service, of said second later version of the application service provision runtime library, of said request; and

at least one processor coupled to the storage medium to execute the programming instructions.

9. The apparatus of claim 8, wherein said second later version of the runtime library is a selected one of the most current version of the runtime library and a predecessor version of the most current version of the runtime library.

10. The apparatus of claim 8, wherein said second later version of the runtime library is a selected one of an immediate successor version of said first version of the runtime library, and a successor version of greater than one generation removed from said first version of the runtime library.

11. The apparatus of claim 8, wherein said second later version of the runtime library is a successor version of greater than one generation removed from said first version of the runtime library, and dispatcher is further equipped to notify a third update service of an immediate successor version of said first version of the runtime library to update said application to said immediate successor version of the first version of the runtime library, and to receive notification from said dispatcher of completion upon upgrading said application to said immediate successor version of the first version of the runtime library.

12. The apparatus of claim 8, wherein said second later version of the runtime library is greater than one generation removed from said first version of the runtime library, and the dispatcher is further equipped to notify a third update service of an immediate predecessor version of said second version of the runtime library to update said application to said immediate predecessor version of the second version of the runtime library, and to notify said dispatcher of completion upon upgrading said application to said immediate predecessor version of the second version of the runtime library.

13. The apparatus of claim 8, wherein said second later version of the runtime library is a successor version of greater than one generation removed from said first version of the runtime library, said dispatcher notifying said second update service of said second version of said application service provision runtime library of said request directly, and said second update service upgrading said application to said second version of the runtime library.

14. An apparatus comprising:

storage medium having stored therein programming instructions designed to implement a first version of an application service provision runtime library, including a first update service equipped with the ability to

receive a request from an application to update the application to a second later version of the application service provision runtime library, and

notify a selected one of

a second update service of the second later version of the application service provision runtime library of said request, and

a dispatcher of the apparatus of said request; and
