"Oracle® Database Reference 10g Release 2 (10.2) B14237-04"
Oracle数据库参考手册是Oracle公司发行的一份详细的技术文档,适用于10g Release 2(10.2)版本。这份文档主要作者是Kathy Rich,并由众多贡献者共同完成,旨在提供对Oracle数据库系统全面的参考信息。手册涵盖了从基本概念到高级特性的广泛内容,是开发人员、DBA和IT专业人员的重要参考资料。
在Oracle 10g Release 2中,你将找到以下关键知识点:
1. 数据库体系结构:手册详细解释了Oracle数据库的物理和逻辑组件,如数据文件、控制文件、重做日志文件、表空间和段等,以及内存结构如SGA(System Global Area)和PGA(Program Global Area)。
2. SQL语言:涵盖SQL的全部语法和用法,包括数据查询、插入、更新、删除、索引、视图、存储过程、函数、触发器等。此外,还包含PL/SQL编程语言的详细信息,这是Oracle数据库中的过程式编程语言。
3. 数据库管理:包括数据库创建、备份与恢复、性能优化、安全性设置、用户管理、权限控制、数据库连接和会话管理等内容。
4. 数据类型:介绍Oracle支持的各种数据类型,如NUMBER、VARCHAR2、DATE、TIMESTAMP、BLOB、CLOB等,以及如何适当地使用它们来存储不同类型的数据。
5. 存储结构:深入解析Oracle的行存储方式、块结构、索引组织表(IOT)、表分区和表压缩等特性。
6. 高可用性和容错性:讨论RAC(Real Application Clusters)、数据守护进程、闪回技术、归档日志模式以及故障恢复策略,确保数据库的高可用性和灾难恢复能力。
7. 并发控制:介绍Oracle的多版本并发控制(MVCC)和锁定机制,以及死锁检测和避免。
8. 性能监控和调优:讲解如何使用AWR(Automatic Workload Repository)、ASH(Active Session History)和SQL Trace等工具进行性能分析和优化。
9. 分区和分片:阐述Oracle的分区技术,包括范围分区、列表分区、哈希分区和复合分区,以及全局和局部索引的应用。
10. 网络配置:包括Net Services配置,如监听器、服务名和连接字符串,以及SQL*Net的配置和故障排查。
11. 安全性:涉及用户认证、授权、审计、角色和数据库加密等方面,确保数据的安全性。
12. 数据库升级和迁移:指导如何从早期版本升级到10g Release 2,以及与其他数据库系统的数据迁移。
通过这份参考手册,你可以获取到关于Oracle 10g Release 2数据库的全面知识,无论是对于日常操作还是问题解决,它都提供了详尽的指南和支持。
