Abstract: A system and method for identifying bugs in a database system. In one embodiment, a method includes running a plurality of tests on a software application, and rerunning one or more tests of the plurality of tests. The method also includes identifying one or more bugs in the one or more tests based on inconsistent test results.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for facilitating spin mode-based dynamic updating of application servers. 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.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for facilitating dynamic zero-downtime updating of formats of software applications in an on-demand services environment. In one embodiment and by way of example, a method includes receiving a request to facilitate a format change to a current version of a software application at a computing device, and retrieving a trigger corresponding to the format change, where a trigger may include a version indicator to indicate a past version of the software application relating to the format change. The method may further include comparing the current version and the indicated past version of the software application, and invoking the format change to the current version of the software application based on the retrieved trigger and the version indicator.

Abstract: Horizontal splitting of tasks within a homogenous pool of virtual machines. A primary virtual machine is provided to service requests from a request source during a session. The primary virtual machine services requests having a first priority received during the session. A secondary virtual machine is provided to service requests from the request source during the session. The secondary virtual machine services requests having a second priority received during the session. The first virtual machine and the second virtual machine run on a single physical computing platform.

Abstract: A system and method for identifying bugs in a database system. In one embodiment, a method includes running a plurality of tests on a software application, and rerunning one or more tests of the plurality of tests. The method also includes identifying one or more bugs in the one or more tests based on inconsistent test results.

Abstract: Detection of skew in an on-demand database services environment is provided. A request is generated to scan a multitenant database for skew indicated by relationship depth exceeding an expected limit. A database crawler calculates skew for tenant identifier for a particular table in the database. Any skew that is detected is identified for later resolution.

Abstract: In accordance with embodiments disclosed herein, there are provided mechanisms and methods for automating deployment of applications in a multi-tenant database environment. For example, in one embodiment, mechanisms include managing a plurality of machines operating as a machine farm within a datacenter by executing an agent provisioning script at a control hub, instructing the plurality of machines to download and instantiate a lightweight agent; pushing a plurality of URL (Uniform Resource Locator) references from the control hub to the instantiated lightweight agent on each of the plurality of machines specifying one or more applications to be provisioned and one or more dependencies for each of the applications; and loading, via the lightweight agent at each of the plurality of machines, the one or more applications and the one or more dependencies for each of the one or more applications into memory of each respective machine.
