Oracle 数据库 Data Guard 容灾配置最佳实践方案
Oracle 数据库的 Data Guard 是一种高可用性和灾难恢复解决方案，它允许数据库在一个或多个远程位置进行复制，从而在主数据库发生故障时提供快速的数据恢复。本文将围绕 Oracle 数据库 Data Guard 的容灾配置，提供一系列最佳实践方案，旨在帮助数据库管理员（DBA）构建一个稳定、高效的容灾系统。
1. 环境准备
在配置 Data Guard 之前，需要确保以下环境准备：
1.1 硬件要求
- 主数据库服务器和备用数据库服务器应具有足够的硬件资源，包括 CPU、内存和存储。
- 确保网络带宽足够，以支持数据复制。
1.2 软件要求
- 安装 Oracle 数据库软件，并确保所有组件版本兼容。
- 安装 Oracle Grid Infrastructure（GI）和 Oracle RAC（如果需要）。
1.3 网络配置
- 配置主数据库服务器和备用数据库服务器之间的网络连接。
- 确保网络延迟和丢包率在可接受范围内。
2. Data Guard 配置步骤
2.1 创建物理备用数据库
1. 在主数据库上启用归档日志模式。
2. 在备用数据库上创建一个物理备用数据库。
```sql
-- 在主数据库上启用归档日志模式
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE OPEN;
-- 在备用数据库上创建物理备用数据库
