Oracle 11gR2 物理备库的搭建及切换

Oracle 11gR2 物理备库的搭建及切换

在同一台机器上搭建物理备用数据库的步骤

实验环境：Linux环境 Oracle 11.2.0.1

主库：orcl

备库：stby

1 检查监听是否启动

2 配置主备数据库的初始化参数文件
sqlplus "/as sysdba"
create pfile='/home/Oracle/initprim.ora' from spfile;
cp /home/oracle/initprim.ora /home/oracle/initstby.ora

编辑备库的参数文件:

备份主库:
rman target /
backup database format '/u01/oradata/dbfull%U';
