首页Oracle数据库参考10g:核心技术详解
"Oracle数据库手册10g是Oracle公司官方发布的一份技术文档,主要针对Oracle Database 10g Release 1 (10.1)版本。这份参考指南由众多专家共同编撰,旨在为数据库管理员、开发人员和其他IT专业人员提供关于Oracle数据库10g的详细信息和操作指南。手册涵盖了各种主题,包括SQL语法、PL/SQL编程、数据库管理、性能优化以及安全性等。"
Oracle数据库10g作为一款强大的关系型数据库管理系统,引入了许多新特性和改进,以提高性能、可用性和可管理性。以下是一些关键的知识点:
1. **Real Application Clusters (RAC)**: Oracle 10g引入了RAC,允许在多台服务器上共享同一个数据库,提高了高可用性和负载均衡能力。RAC通过Grid Infrastructure提供故障切换和数据访问透明性。
2. **Automatic Storage Management (ASM)**: ASM是一个集成的存储管理解决方案,简化了数据库存储的管理和维护,自动处理磁盘管理和数据放置。
3. **Data Guard**: 提供灾难恢复和数据库保护,通过创建和维护一个或多个备用数据库,可以在主数据库出现故障时无缝切换。
4. **SQL Enhancements**: 包括新的SQL功能,如Analytic Functions、Recursive Subquery Factoring(递归子查询因子)和Materialized Views,以增强数据分析和报表生成能力。
5. **PL/SQL Enhancements**: 提供了更好的调试工具、改进的异常处理和新的包管理功能,增强了PL/SQL的编程体验。
6. **Memory Management**: 引入了Automatic Memory Management,自动调整SGA和PGA的大小,以优化性能。
7. **Performance and Tuning**: 包括自动工作负载 repository (AWR) 和自动数据库诊断监视器 (ADDM),帮助识别和解决性能问题。
8. **SecureFile**: 改进了LOB(大型对象)存储,支持加密、压缩和直接I/O,提高了安全性和效率。
9. **XML Support**: 加强了对XML的支持,包括XMLDB,一个内置的XML存储和处理引擎,以及XQuery和XPath支持。
10. **Application Continuity**: 保证应用程序在数据库错误后能够继续运行,减少了事务失败的可能性。
11. **Grid Infrastructure**: 提供了一种集中式的管理和控制方式,使得在分布式环境中部署和管理Oracle数据库变得更加简单。
这份Oracle数据库10g参考手册是理解、管理和优化Oracle 10g数据库的关键资源,其中包含了详细的操作指南、语法参考、配置建议以及故障排除信息,对于深入学习和实际操作非常有帮助。无论是初学者还是经验丰富的专业人士,都能从中获取所需的信息来提升对Oracle数据库的理解和应用能力。
