ORACLE APPLICATION SERVER 10g GRID COMPUTING FEATURES. Oracle Application Server 10g. Oracle Application Server 10g, component of Oracle Fusion Middleware, has been specifically designed to run enterprise applications on computing grids. It is designed to run enterprise applications on pools of low cost servers and storage with very high performance, scalability, and availability while radically reducing the costs of systems and applications monitoring and management. Further, customers can deploy all their existing Oracle9iAS applications on Application Server 10g without any changes and take advantage of the new grid features. OracleAS 10g is managed by Oracle Enterprise Manager 10g Grid Control, a web-based management console that enables administrators to manage many application servers as though they were one, thereby automating administrative tasks and reducing administrative costs. Grid Control also provides facilities to enable many administrators to work together to manage an application server grid. Finally, OracleAS 10g is also integrated with Oracle Database 10g in many different ways to optimize quality of service across a unified grid computing infrastructure for data management and enterprise applications. Before we examine the specific features OracleAS 10g provides for grid computing, it is important to first understand the characteristics of grid computing that drive the need for these features. Grid Computing Characteristics: An enterprise computing grid is characterized by three primary features – Diversity; Decentralization; and Dynamism. Diversity: A typical computing grid consists of many hundreds of managed resources of various kinds including servers, storage, Database Servers, Application Servers, Enterprise Applications, and system services like Directory Services, Security and Identity Management Services, and others. Managing these resources and their life cycle is a complex challenge. Decentralization: Traditional distributed systems have typically been managed from a central administration point. A computing grid further compounds these challenges since the resources can be even more decentralized and may be geographically distributed across many different data centers within an enterprise. Dynamism: Components of a traditional application typically run in a static environment without the needing to address rapidly changing demands. In a computing grid, however, the systems and applications need to be able to flexibly adapt to changing demand. For instance, with the late binding nature and cross- platform properties of web services, an application deployed on the grid may consist of a constantly changing set of components. At different points in time, these components can be hosted on different nodes in the network. Managing an application in such a dynamic environment can be a challenging undertaking. These are just three of the most important challenges associated with running enterprise applications in a grid computing environment. Recognizing these challenges, Oracle designed its software infrastructure to run enterprise applications, OracleAS 10g, to specifically address these and other challenges…
