ORACLE11G RMAN备份恢复到异机数据库


1. 源数据库环境


操作系统版本:Centos6.7x64

数据库版本:Oracle11.2.0.4x64


数据库名: prb


数据库SID :prb


db_unique_name : prb


instance_name : prb


IP : 10.0.8.100


2. 目标数据库环境


操作系统版本:Centos6.7x64


数据库版本:Oracle11.2.0.4x64(只安装oracle数据库软件,nonetcadbca)


数据库名:prb


数据库SID:prb


db_unique_name:prb


instance_name:prb


IP:10.0.8.101


将参数文件备份、控制文件备份、数据文件备份、以及归档备份到目标主机


1 此处实验环境为同平台,同字节序,同版本,源机器和目标机器相同的目录结构。


2 目标机器只需要安装oracle只安装oracle数据库软件,nonetcadbca


3 第一次利用备份恢复测试环境,之后从源机器拷贝备份到目标机器并在控制文件中注册,再见行恢复测试。


备份数据库


backup format '/u01/prb/rmanbk/fulldb_%d_%U' database includecurrent controlfile plus archivelog delete input;


orapwdfile='/u01/app/oracle/product/11.2.0.4/db_1/dbs/orapwprb' password=oracleentries=10 force=y


1rman 连接到源数据库


prd-db1-> rman target /

2 分别列出参数文件备份,控制文件备份,数据文件备份,以及归档备份的名字


参数文件备份如下:


RMAN> list backup of spfile;
