Oracle DataBase单实例迁移到Oracle RAC - 数据库编程

--------------------------------------分割线 --------------------------------------

迁移前单实例环境介绍：

数据库版本：Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - Production

数据库物理结构：

RMAN> report schema;

using target database control file instead of recovery catalog
Report of database schema

1. 单节点数据库备份

注：单节点数据库的备份已经传送到/u02目录下，直接执行下面的解压即可。

[oracle@rac1 u02]$ cd /u02
[oracle@rac1 u02]$ tar zxvf backup_db.orcl.tar.gz
