总体概述：
A线上库      源库
B线下库      目标库
采用的方式   rman

1 使用rman 全量备份线上A数据库

CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/data/back/%F';
run {
allocate channel ch1 device type disk;
allocate channel ch2 device type disk;
allocate channel ch3 device type disk;
allocate channel ch4 device type disk;
backup full
filesperset=2
tag='Full_%d'
format='/data/backup/%T_full_%d_%s_%p'
database include current controlfile;
release channel ch1;
release channel ch2;
release channel ch3;
release channel ch4;
}

 
2 将备份文件scp到B机对应的目录下面
  A机创建pfile文件scp到对应目录下

3开始恢复

加载pfile文件
export ORACLE_SID=rman
sqlplus "/as sysdba"

SQL> startup pfile='/home/oracle/product/10.2.0/dbs/initrman.ora' nomount;
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_RMAN'
ORA-01078: failure in processing system parameters
修改pfile参数
注意AB数据库大版本要一致，小版本B库要大于等于A库
LOCAL_LISTENER='(ADDRESS = (PROTOCOL = TCP)(HOST = 10.25.5.43)(PORT = 1521))'

3.1 数据库B到nomount下，恢复控制文件

[oracle@grid ~]$ rman target /

connected to target database: rman (not mounted)

RMAN> set DBID=1564188787

executing command: SET DBID

RMAN> restore controlfile from '/data/back/c-1564188787-20100208-03';

3.2 B数据库到mount下，恢复数据库文件

SQL> alter database mount;

RMAN> restore database from tag='FULL_GPODB_DATA';

RMAN> recover database;

RMAN> recover database;

Starting recover at 08-FEB-10
using channel ORA_DISK_1

starting media recovery

日志有问题，因为没有备份日志，没有日志可用于恢复；

奇怪的是alter database open resetlogs;不能打开报需要用
SQL> alter database open upgrade;   在mount下执行
这估计发生这个情况的原因是B数据库的版本是10.2.0.3.0,A库是10.2.0.2.0导致的。

关闭数据库再开启数据库同样的报错
SQL> startup
ORACLE instance started.

ORA-01092: ORACLE instance terminated. Disconnection forced
查看日志发现
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
分析原因是B数据库没有升级，迁移过来的数据库是A数据库版本的
升级数据库问题得到解决

sqlplus /nolog
conn /as sysdba
startup upgrade
spool patch.log
@?/rdbms/admin/catupgrd.sql
spool off
shutdown immediate
startup
启LISTENER
lsnrctl start
启Oracle Enterprise Manager
emctl start dbconsole

验证下数据库的可用性. OK
