拷贝密码文件：

cp orapwhellodb /data/oracle/product/10205/db1/dbs/

B  恢复:

export ORACLE_SID=hellodb

rman target /

startup nomount;

restore controlfile   from '/data/backup/stdctl_hellodb.ctl';

根据

output filename=/data/oracle/oradata/hellodb/controlhellodb01.ctl

修改

control_files = /data/oracle/oradata/hellodb/controlhellodb01.ctl

startup mount;

catalog start with '/data/backup';

在备库恢复数据库

run{

allocate channel d1 type disk;

allocate channel d2 type disk;

allocate channel d3 type disk;

allocate channel d4 type disk;

 restore database;

 release channel d1;

 release channel d2;

 release channel d3;

 release channel d4;

 }

C 打开恢复进程（如果没有STANDBY LOGFILE ，应该增加）：

ALTER DATABASE ADD STANDBY  LOGFILE THREAD 1 GROUP 4 ('/data/oracle/oradata/hellodb/stdlog_5_1.log') SIZE 50M;

ALTER DATABASE ADD STANDBY  LOGFILE THREAD 1 GROUP 5 ('/data/oracle/oradata/hellodb/stdlog_6_1.log') SIZE 50M;

ALTER DATABASE ADD STANDBY  LOGFILE THREAD 1 GROUP 6('/data/oracle/oradata/hellodb/stdlog_7_1.log') SIZE 50M;

shutdown immediate

startup mount

alter database recover managed standby database disconnect from session using current logfile;

D 转逻辑备库

02 先停止

alter database recover managed standby database cancel;

52 执行

SQL> exec dbms_logstdby.build;

PL/SQL procedure successfully completed.

SQL> alter system archive log current;

System altered.

02  执行

SQL> ALTER DATABASE RECOVER TO LOGICAL STANDBY hellodb;

ALTER DATABASE RECOVER TO LOGICAL STANDBY hellodb

Additional information: 3

shutdown immediate

startup mount

alter database open resetlogs;

alter database start logical standby apply immediate;

52 执行（如果日志没有传过来，该操作会立即激活传输）

shutdown immediate

startup
