Mechanism for facilitating spin mode-based dynamic updating of application servers in an on-demand services environment
First Claim
1. A database system-implemented method, comprising:
- retiring, by the database system, a first computing device of a cluster of computing devices for upgrading from a first current version to a first new version;
dynamically holding, by the database system, a first processing request, set to be processed by the first new version, in a wait stage while the first computing device is retired to be upgraded to the first new version;
continue facilitating, by the database system, uninterrupted processing of a second processing request by a second current version of a second computing device of the cluster of computing devices while the first computing device remains retired;
upgrading, by the database system, the first computing device from the first current version to the first new version;
selectively routing, by the database system, the first processing request from the wait stage to the first computing device such that the first processing request is processed by the first new version of the first computing device;
retiring the second computing device from the cluster of computing device to be upgraded to the second new version;
holding, in a second wait stage, a third processing request to be processed by the second new version of the second computing device; and
selectively routing the third processing request from the second wait stage to the second computing device such that the third processing request is processed by the second new version of the second computing device.

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.
