Embodiment Construction

[0033] The apparatus and methods described herein provide for dividing a set of commands into individual commands and distributing the commands to multiple computing devices, and then combining the results of the executed commands. A system including the computing devices may be referred to as a processing farm. In certain aspects, each of the computing devices use the same method. The method may begin with each of the computing devices attempting to become a master. One of the computing devices succeeds and becomes the master and each of the remaining computing devices becomes slaves. Advantageously, the method can be implemented independently by each computing device without requiring a separate controller to identify the master device. Commands are submitted to the master device for execution. The master device divides the plurality of commands into individual commands. For example, the multiple commands can be received together in, for example, a script and a load bala...

Abstract

Apparatus and methods in a load balancer computing apparatus include, in aspects, determining if a master is functioning, and if the master is not functioning, then attempting to become the master by setting a master network identification in a master database table to a self network identification before at least one other slave sets a corresponding other slave network identification as the master network identification in the master database table. In other aspects, the apparatus and methods include assigning each of a group of commands to one of a plurality of slaves, storing the commands and a corresponding assignment in a database table, checking a command status in the database table for each of the group of commands, wherein the command status indicates whether or not the respective command has been executed; and executing a callback function when all the commands are executed.

Description

[0001] Priority claims under 35 U.S.C. §119 [0002] This patent application requests the 60 / th of the titled "METHOD AND APPARATUS FOR SUPPORTING ZEROSINGLE POINT OF FAILURE LOAD BALANCER" filed on December 5, 2006. 868,689, assigned to the assignee of the present application, and is hereby expressly incorporated by reference herein. technical field [0003] The illustrated aspects relate to distributed processing systems, and more particularly to apparatus and methods for zero single point of failure load balancers. Background technique [0004] In computer processing, a set of commands can often be divided into individual commands. The commands can be executed in parallel, and the results can then be combined. Additionally, since a single computing device has limited processing capabilities, multiple computing devices may be used to execute the commands. However, using more than a single computing device can create problems in distributing and combining commands among...
