1. 源数据库环境
操作系统版本 : Centos6.7 x64
数据库版本 : Oracle 11.2.0.4 x64
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 : Centos6.7 x64
数据库版本 : Oracle 11.2.0.4 x64 (只安装oracle数据库软件,no netca dbca)
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,no netca dbca
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
1 rman 连接到源数据库
