The third leg of the grid stool is Oracle Enterprise Manager 10G, which sits on top of both the database and the application server. The update introduces automated management that lets DBAs enforce policies, manage service levels, and rebalance computing resources and applications as business requirements shift. Central to OEM 10Gs grid management is new software called Oracle Grid Control. The software is designed for monitoring and management of grids, including databases, applications and storage, within one console. At its core is a control repository with performance, availability and configuration data that enables Grid Control to offer recommendations on those topics. It also transforms and configures data into usable information.Jeremy Forman, a computer systems analyst for the New Mexico Department of Transportation, is beta testing Application Server 10G and OEM 10G with the goal of better handling of a large multimedia database with some 5 million stored images of assets along a 30,000-mile system, including signs, guardrails or culverts. Eventually, his department wants to construct a virtual drive-through of the states roads. Its not grid that gets Formans approvalrather, its the self-management aspects of the new architecture. "Im the only DBA in the department," he said. "10Gs offering so many automation features. Ive used OEM extensively. Im excited about production with 10G because it allows me to automate day-to-day stuff: managing table spaces, and performance tuning more than anything. It offers you a fix on the fly without having to go through the process of finding it out yourself." Application Server 10G, OEM 10G and OEM 10G Grid Control will be available at years end. Members of OTN (Oracle Technology Network) can download OEM 10G and OEM 10G Grid Control free at otn.oracle.com. Oracle didnt disclose pricing details.
OEM 10G is built on an open, standards-based architecture and supports management standards including CIM (Common Information Model) and WBEM (Web-based Enterprise Management).
