Oracle 10g Database Administration Overview
Oracle 10g数据库管理是Oracle公司发布的一款重要的企业级数据库管理系统,主要针对数据库的管理和维护。本资料《Oracle 10g Database Administration: Concepts & Implementation Made Simple》简化Oracle 10g数据库的管理概念及实施过程,帮助IT专业人员深入理解并熟练掌握这一系统。 Oracle 10g基础 数据库版本:Oracle 10g是Oracle数据库的第10个主要版本,首次引入了Real Application Clusters (RAC)和Data Guard等关键特性。 数据存储:Oracle 10g使用表空间和数据文件来组织和存储数据,表空间是逻辑存储单元,数据文件则是实际存储数据的物理文件。 数据库实例:由内存结构(如SGA)和后台进程组成的运行时环境,用于处理数据库请求。 数据库架构 表、视图与索引:数据库的核心组件,表存储数据,视图提供虚拟表,索引提高查询速度。 分区与分段:大型数据库常用技术,通过将大表或索引划分为更小的部分来提高性能和管理效率。 存储优化:包括自动存储管理(ASM)、重做日志文件和控制文件的管理,以确保数据安全和高效访问。 数据库管理 安装与配置:涉及操作系统级别的设置、软件安装、网络配置和数据库创建。 性能监控与调优:通过SQL*Plus、企业管理器(EM)和其他工具分析资源使用情况,调整参数以提升性能。 备份与恢复:Oracle提供多种备份策略,如完整备份、增量备份和归档日志备份,结合RMAN工具实现恢复操作。 高可用性与灾难恢复 RAC(Real Application Clusters):允许多台服务器共享同一数据库,提高可用性和性能,降低单点故障风险。 Data Guard:通过创建物理或逻辑备用数据库,实现灾难恢复和故障切换,确保业务连续性。 安全性 用户权限与角色:通过用户、口令、权限和角色管理数据库访问权限,保障数据安全。 审计:记录数据库活动,以便追踪和调查潜在的安全问题。 加密:用于保护数据库中的敏感数据。

Oracle 11g DataGuard Concepts and Administration Guide
In this Oracle 11g DataGuard guide, we explore the fundamental concepts and administration best practices for managing DataGuard environments. DataGuard is a robust disaster recovery and data availability solution for Oracle databases. It enables high availability by synchronizing a primary database with one or more standby databases. Key DataGuard configurations include physical standby, logical standby, and snapshot standby, each serving distinct use cases for data redundancy and backup. Key Components of Oracle 11g DataGuard Primary Database: The main operational database actively servicing data requests. Standby Database: A backup database maintained as a replica, either in physical or logical standby mode. DataGuard Broker: A management framework that simplifies configuration and monitoring. DataGuard Modes DataGuard offers three protection modes to balance performance and data protection:1. Maximum Protection: Ensures zero data loss by requiring a standby database write for every transaction.2. Maximum Availability: Balances availability with potential minimal data loss if the standby is temporarily unavailable.3. Maximum Performance: Prioritizes performance and reduces overhead on the primary database. Oracle DataGuard provides advanced data management techniques like failover, switchover, and role transitions to enable uninterrupted data access and reliable disaster recovery.
