  • Let’s start with an overview of Oracle. Today, we are an $11B company. We are the world’s largest enterprise software company, and together with our 12,000 partners, we support more than 250,000 customers in over 145 countries. We have 42,000 employees, 8,000 of them are developers. We spent about 10% of our annual revenues on R&D. We leverage our people, our global resources, and our partners to help our customers solve their business needs.
  • Oracle 9i includes the 9i database, 9i Developer Suite, and the 9i Application Server. Oracle 9i Internet Platform is the complete internet infrastructure that helps customers deploy applications faster, while lowering the cost of computing. Oracle 9i database and Oracle 9i Application Server deliver the industry’s highest performance, reliability, and security for thousands of popular applications. Oracle took advantage of the reliability, fault tolerance, power, and security features of the 9i Internet Platform to reap the benefits of Global Consolidation.
  • ORACLE9 i - THE EBUSINESS PLATFORM Oracle9 i continues Oracle8 i 's focus on the Internet by providing a series of specific capabilities and product bundles targeted at eBusiness environments. In addition, Oracle9 i continues to add features and capabilities that extend existing investment in mission-critical infrastructure. Oracle9 i has been designed with focus on certain key development areas. These areas are: Key Infrastructure Areas Availability Scalability and Performance Security Development Platform Manageability Windows2000 Integration Key Application Areas Internet Content Management B2C and B2B e Business Packaged Applications Business Intelligence
  • Oracle also developed and uses the Oracle E-Business Suite. The E-Business Suite is the industry’s first integrated suite of internet business applications that automates critical business processes across both front and back office operations. In 2001, the Oracle E-Business Suite, which streamlines every area of a business --marketing, sales, service, procurement, supply chain, manufacturing, financials and human resources-- was implemented by more than 1,100 companies around the world. Now, more than 12,000 customers are currently enjoying the benefits of the Oracle E-Business Suite.
  • Evolution of Oracle re: management functionality important in data warehousing and the trend toward self-tuning & management features.
  • Benefits of Cache Fusion Cache Fusion removes the pinging (disk writes and reads) required to transfer blocks being modified by multiple instances between those instances. It extends and replaces the functionality of the Consistent Read Server, introduced in Oracle8 i , which serviced requests to read blocks changed in another instance, by allowing any block being held by any instance to be copied to another instance across the cluster interconnect. By providing fast transfers of blocks, Cache Fusion allows Oracle Real Application Clusters to perform data access as fast, or faster, than single instances which need to access multiple blocks by reading them from disk. Even with the overhead of the DLM, this allows any application to run without degradation on Oracle Real Application Clusters. Under previous releases of Real Application Clusters (or Oracle Parallel Server, the name used in those releases), some applications would not scale well because the block pinging algorithm caused too many disk writes and reads between instances. This could be avoided by partitioning the data, the application, or the users across instances, but this was not always possible—for example, with third party applications—or desirable due to the costs associated with modifying the data or the application.. To ensure that Cache Fusion provides the highest level of block transfer rates, the cluster interconnect should be based on fast interconnect technologies with low latency. This includes high-speed Ethernet and technologies based on the Virtual Interface Architecture (VIA) messaging API and hardware, such as GigaNet and ServerNet.
