Embodiment Construction

[0024] The present invention describes a method and apparatus for accessing data sources. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it is understood that the invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

[0025] A. Overview

[0026] According to one embodiment, a retry point is designated for the sequential components that make up the communication path between the client and the data source. The designated retry component is provided on one of the components in the communication path. If the communication from the client to the data source fails to reach its destination, then the specified retry component is the only component that retries sending the client communication to its des...

Abstract

A system is provided to manage retry communications between a client and a data source. The system includes a plurality of logical components that sequentially combine to form a communication path for a client communication. At least one of the components in the communication path is designated as a retry component. The retry component retries failed client communications for all of the components in the communication path.

Description

technical field [0001] The present invention relates to managing communications over a network. In particular, the embodiments of the present invention belong to the retry technology of a multi-layer network communication system. Background technique [0002] Network applications that handle client-server type communications are becoming increasingly complex. A typical client-server communication involves the client sending a request to the server, and the server returning a response to the client. A server usually consists of multiple logical components that process client requests. Client requests are typically processed in some fashion by various logical components of the server before a response is generated in response to the client request. [0003] In a typical application, a server accesses a data source to retrieve information needed by a client in response to a client request. Each logical component of the server functions on a client request before sending it ...
