Oracle 11g DataGuard容灾方案详解

这份教程将引领你逐步掌握 Oracle 11g DataGuard 的配置和使用，助你构建高可用性的数据库环境。

详细介绍了在ORACLE 11G平台上配置DATAGUARD的步骤，同时总结了操作后的经验和注意事项。

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.

Cluster Interconnect和Public LAN是网络配置的关键部分。每个节点需要三个IP地址：一个公共服务地址（用于客户访问），一个私有的内部地址（仅内部使用），一个虚拟IP地址（与公共服务地址在同一网段）。此外，每个集群需要一个SCAN IP地址，用于应用访问。
