RMAN备份和恢复
异地RMAN恢复，更改数据文件位置；
一 RMAN全备
(1)RMAN全备
(2)创建测试数据
二 RMAN恢复
(1)恢复参数文件
(2)恢复控制文件
(3)修改控制文件中记录的rman相关路径信息
(4)恢复数据库
(5)验证数据

(2)创建测试数据
---创建测试表2018-07-02 14:30
conn chenjch/***
select * from user_tables;
create table test20180702 as select level as id from dual connect by level<=1000;
select * from test20180702;
---切换日志
alter system switch logfile;
alter system checkpoint;
二 RMAN恢复
---备份文件恢复到其他服务器上，并更改备份文件路径，数据文件路径；
(1) 恢复参数文件
RMAN> startup nomount
RMAN>
restore spfile to 'D:\app\Administrator\product\11.2.0\dbhome_1\database\SPFILECHENJCHORCL.ORA' from 'D:\backup_nfs\rman\RMAN_FULL_CHENJCHORCL_20180702_4QT6UTM7_1_1.BAK';
SQL> shutdown immediate
SQL> create pfile='D:\app\Administrator\product\11.2.0\dbhome_1\database\INITeasorcl.ORA' from spfile='D:\app\Administrator\product\11.2.0\dbhome_1\database\SPFILECHENJCHORCL.ORA';
---提前根据参数文件创建或修改目录
SQL> startup nomount pfile='D:\app\Administrator\product\11.2.0\dbhome_1\database\INITeasorcl.ORA';
(2) 恢复控制文件
RMAN>
restore controlfile from 'D:\backup_nfs\rman\RMAN_CTL_CHENJCHORCL_20180702_4TT6UULU_1_1.BAK';
SQL> alter database mount;
(3) 修改控制文件中记录的rman相关路径信息
RMAN> list backup; ---查看控制文件中记录的数据文件位置等信息;
RMAN> list backup of archivelog all; ---查看控制文件中记录的归档位置等信息；
---将备份文件注册到控制文件(原库部分文件目录和目标库备份文件目录不一致时，需要执行注册)；
RMAN> catalog backuppiece 'D:\backup_nfs\rman\RMAN_FULL_CHENJCHORCL_20180702_4NT6USSD_1_1.BAK';
RMAN> catalog backuppiece 'D:\backup_nfs\rman\RMAN_FULL_CHENJCHORCL_20180702_4PT6UTLS_1_1.BAK';

RMAN> catalog backuppiece 'D:\backup_nfs\rman\RMAN_ARC_CHENJCHORCL_20180702_4ST6UUE0_1_1.BAK';
---归档位置(原库归档目录位置和目标库备份文件目录不一致时，需要执行注册)；
