今年6月,Oracle公司经过多次延误后最终发布了Oracle 8,Oracle大力宣传的Oracle 8新功能如可伸缩性、对象关系技术,都是Informix DSA早已实现多年的技术,可以看出Oracle极力想通过Oracle 8缩小与Informix的技术差距。体系结构与数据库核心 Informix DSA,是Informix在90年代为SMP、Cluster、MPP这些并发硬件体系结构重新开发的动态可伸缩体系结构,在数据库核心采用多线索内核并发技术,因此DSA所有类型的数据和所有的数据库操作都可以并发处理。由干用户的数据库操作是以多线索方式处理,每个用户连
In June of this year, Oracle Corporation released Oracle 8 after numerous delays. Oracle’s new Oracle 8 features such as scalability and object-relationship technologies are technologies that have been implemented by Informix DSA for many years. It can be seen that Oracle strongly Reduce the technology gap with Informix through Oracle 8. The architecture and database core Informix DSA is a dynamic and scalable architecture that Informix redeveloped in the 1990s for concurrent hardware architectures such as SMP, Cluster, and MPP. In the database core, multi-threaded kernel concurrency technology is used, so all types of DSA data and All database operations can be processed concurrently. Database operations by dry users are handled in multiple threads, with each user
