1. copy standby control file from primary db to standby db and rename the file name and location in stdby db same as the primary db

2. copy password file from primary db to the standby db (keep both of them same )

3. use the pfile to startup the standby database using  >>>>>>>>>>

SQL> conn sys@brsstby as sysdba
输入口令:
已连接到空闲例程。
SQL> startup nomount pfile=‘d:\pfileBRS.ora‘
ORACLE 例程已经启动。startup nomount  pfile= ‘

 >>>use recovery catalog to duplicate database

rman target  sys/oracle@BRS  auxiliary sys/oracle@BRSSTBY catalog rman/rman001@RMANDB
