Abstract

In accordance with embodiments, there are provided mechanisms and methods for facilitating spin mode-based dynamic updating of application servers in an on-demand services environment. In one embodiment and by way of example, a method includes upgrading a first set of application servers of a plurality of application servers at one or more computing devices, holding a first set of requests received at the first set of application servers from being processed while the first set of application servers is being upgraded, and upgrading a second set of application servers of the plurality of application servers upon completion of the first set of application servers. The method may further include holding a second set of requests received at the second set of application servers from being processed while the second set of application servers is being upgraded, and resuming processing of the first set of requests at the upgraded first set of application servers.

Claims

1-15. -15. (canceled)

16. A database system-implemented method, comprising:

holding, in a first wait stage, by the database system, a first processing request to be processed by a first new version of a first computing device of a cluster of computing devices, wherein the first processing request is placed in the first wait stage while the first computing device is upgraded from a first current version to the first new version;

continue processing, by the database system, a second processing request at a second computing device of the cluster of computing devices, wherein the second processing request is specific to a second current version of the second computing device;

upgrading, by the database system, the first computing device from the first current version to the first new version; and

selectively routing, by the database system, from the first wait stage, the first processing request to the first computing device, wherein the first processing request is processed by the first new version of the first computing device.

17. The method of claim 16, further comprising:

prior to upgrading the first computing device to the first new version, retiring, the first computing device from the cluster of computing devices; and

selecting the second computing device for retirement if the second current version at the second computing device is capable of being upgraded to a second new version.

18. The method of claim 17, further comprising:

retiring the second computing device from the cluster of computing device to be upgraded to the second new version; and

holding, in a second wait stage, a third processing request to be processed by the second new version of the second computing device.

19. The method of claim 18, further comprising selectively routing, from the second wait stage, the third processing request to the second computing device, wherein the third processing request is processed by the second new version of the second computing device.

20. The method of claim 16, wherein the first, second, and third processing requests to initiate one or more tasks relating to one or more tenants of a plurality of tenants in a multi-tenant environment, wherein the first, second, and third processing requests are placed by one or more users on behalf of the one or more tenants.

21. The method of claim 16, wherein the first and second current versions and the first and second new versions refers to one or more versions of one or more software applications at one or more computing devices of the cluster of computing devices, wherein the one or more computing devices comprise the first and second computing devices including application servers.

22. A system comprising a processing device and memory coupled with the processing device, wherein the processing device to facilitate operations comprising:

holding, in a first wait stage, a first processing request to be processed by a first new version of a first computing device of a cluster of computing devices, wherein the first processing request is placed in the first wait stage while the first computing device is upgraded from a first current version to the first new version;

continue processing a second processing request at a second computing device of the cluster of computing devices, wherein the second processing request is specific to a second current version of the second computing device;

upgrading the first computing device from the first current version to the first new version; and

selectively routing from the first wait stage, the first processing request to the first computing device, wherein the first processing request is processed by the first new version of the first computing device.

23. The system of claim 22, wherein the operations further comprise:

prior to upgrading the first computing device to the first new version, retiring, the first computing device from the cluster of computing devices; and

selecting the second computing device for retirement if the second current version at the second computing device is capable of being upgraded to a second new version.

24. The system of claim 23, wherein the operations further comprise:

retiring the second computing device from the cluster of computing device to be upgraded to the second new version; and

holding, in a second wait stage, a third processing request to be processed by the second new version of the second computing device.

25. The system of claim 24, wherein the operations further comprise selectively routing, from the second wait stage, the third processing request to the second computing device, wherein the third processing request is processed by the second new version of the second computing device.

26. The system of claim 22, wherein the first, second, and third processing requests to initiate one or more tasks relating to one or more tenants of a plurality of tenants in a multi-tenant environment, wherein the first, second, and third processing requests are placed by one or more users on behalf of the one or more tenants.

27. The system of claim 22, wherein the first and second current versions and the first and second new versions refers to one or more versions of one or more software applications at one or more computing devices of the cluster of computing devices, wherein the one or more computing devices comprise the first and second computing devices including application servers.

28. A machine-readable medium having instructions which, when executed by a machine, cause the machine to perform one or more operations comprising:

holding, in a first wait stage, a first processing request to be processed by a first new version of a first computing device of a cluster of computing devices, wherein the first processing request is placed in the first wait stage while the first computing device is upgraded from a first current version to the first new version;

continue processing a second processing request at a second computing device of the cluster of computing devices, wherein the second processing request is specific to a second current version of the second computing device;

upgrading the first computing device from the first current version to the first new version; and

selectively routing from the first wait stage, the first processing request to the first computing device, wherein the first processing request is processed by the first new version of the first computing device.

29. The machine-readable medium of claim 28, wherein the operations further comprise:

prior to upgrading the first computing device to the first new version, retiring, the first computing device from the cluster of computing devices; and

selecting the second computing device for retirement if the second current version at the second computing device is capable of being upgraded to a second new version.

30. The machine-readable medium of claim 29, wherein the one or more operations further comprise:

retiring the second computing device from the cluster of computing device to be upgraded to the second new version; and

holding, in a second wait stage, a third processing request to be processed by the second new version of the second computing device.

31. The machine-readable medium of claim 30, wherein the one or more operations further comprise selectively routing, from the second wait stage, the third processing request to the second computing device, wherein the third processing request is processed by the second new version of the second computing device.

32. The machine-readable medium of claim 28, wherein the first, second, and third processing requests to initiate one or more tasks relating to one or more tenants of a plurality of tenants in a multi-tenant environment, wherein the first, second, and third processing requests are placed by one or more users on behalf of the one or more tenants.
