OGSA aims to address these issues by defining the basics of a grid application structure that can be applied to any grid system.

Could be used to enhance OGSA to perform reliable and dynamic invocation of a Grid service.

To run a query statement, provide a perform document that includes the query to execute within a SQLQueryStatement activity.

As Figure 1 illustrates, SOAP messages are used for the communication between an OGSA-DAI client and server.

The concept of resources is central to OGSA and to grid computing in general.

Could be used to enhance OGSA to define the complicated relationships among Grid services.

In essence, the OGSA standard defines what grid services are, what they should be capable of, and what technologies they be based on.

This article illustrates the integration of IBM DB2 UDB into a grid environment using the OGSA-DAI framework.

Thus, OGSA is encouraging the hosting environment to make modifications or additions for supporting the grid services.

The tag states that the query result is delivered by the corresponding OGSA-DAI response document.

OGSA also provides a grid security mechanism to ensure that all the communications between services are secure.

You will write the create documents to identify the databases to be accessed through OGSA-DAI.

In the framework of OGSA, all resources are abstracted into grid service and the information of resources is described into service data.

These applications comprise the fourth main layer of the OGSA architecture.

These solutions are intended to use OGSA-compliant services to provide a consistent view of all of the resources within the grid.

See [ 3] for a description of the mechanisms and interfaces defined in OGSA.

A systems architecture is evolving called the Open Grid Service Architecture (OGSA) to identify the components needed in a grid system.

You don't need to iterate through the results row by row because OGSA-DAI returns all the rows together.

In fact, for OGSA to grow in acceptance, OGSI will need to be enabled on multiple hosting platforms.

As we ve seen, the OGSA architecture enhances Web services to accommodate requirements of the grid.

In this article, we lay out the components of OGSA and explain their significance.

Using a tracing mechanism, you can execute the query stepwise to observe every step that OGSA-DAI runs.

Could be used to enhance OGSA to discover grid services.

OGSA defines a service-based structure for creating a grid computing environment.

Based on the design of educational resources OGSA services platform architecture, and through the WSRF.

Provides an overview of the OGSA Architecture.

Then using the OGSA Service browser as a grid service client, you can enter your ZIP code.

An OGSA-DAI create document to create a Grid Data Service for accessing the appropriate DB2 database via OGSA-DAI.

For updating data, OGSA-DAI provides another activity, the SQLUpdateStatement activity (see Figure 6).

An OGSA-DAI perform document to execute SQL queries and updates in DB2 via OGSA-DAI, and to receive responses back.

The research work on OGSA in this thesis is absolutely a meaning try.

Currently, both OGSA and OGSI are works in progress.

Four main layers comprise the OGSA architecture: See Figure 1.

The second layer in the OGSA architecture is Web services.

For inserting binary data into DB2, OGSA-DAI has to read the binary file.

The MMJFS is required to hook up OGSA to the back-end scheduler.

For more information about the whole OGSA-DAI process see [ 5].

From the OGSA specification, is it possible to implement and compose grid services in different ways.
