应用场景：
1、旧库可以使用并且网络顺畅
实验环境：
target db：
ip 192.168.56.10
oracle_sid=mydb
oracle_version=11.2.0.3
auxiliary db：
ip 192.168.56.150
oracle_sid=oradu
oracle_version=11.2.0.3
1、在新库创建参数文件并启动实例到nomount状态
--auxiliary db上执行
[oracle@localhost ~]$ cat initoradu.ora
db_name=oradu
db_block_size=8192
db_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')
log_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')
--由于这里使用的是不同实例，所以必须添加db_file_name_convert和log_file_name_convert，否则在复制的时候会报错无法创建数据文件，如果是同实例名复制，且两数据目录完全一样的情况下，这两个参数可省略。
--在auxiliary db 上创建新库的数据文件在存放的目录
mkdir -p /u01/app/oracle/oradata/oradu/
[oracle@localhost ~]$ export ORACLE_SID=oradu
[oracle@localhost ~]$ sqlplus / as sysdba

2、创建密码文件
--必须保持target DB和auxiliary DB的密码一致。这里我直接把target db的密码文件复制到auxiliary db对应的目录下并重命名
--target db上执行
[oracle@localhost ~]$ scp /u01/app/oracle/product/11.2.0/db/dbs/orapwmydb oracle@192.168.56.150:/u01/app/oracle/product/11.2.0/db/dbs/orapworadu

3、配置target db 和auxiliary db的监听
--auxiliary db必须使用静态监听，否则报错RMAN-04006: error from auxiliary database: ORA-12528: TNS:listener: all appropriate instances are blocking new connections
--auxiliary db
vi /u01/app/oracle/product/11.2.0/db/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
? ? (SID_DESC =
? ? ? (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db)
? ? ? (SID_NAME=oradu)
? ? )
)
vi /u01/app/oracle/product/11.2.0/db/network/admin/tnsnames.ora
mydb =
(DESCRIPTION =
? ? (ADDRESS_LIST =
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.10)(PORT = 1521))
? ? )
? ? (CONNECT_DATA =
? ? ? (SERVICE_NAME = mydb)
? ? ? (SERVER = DEDICATED)
? ? )
)
?--target db
vi /u01/app/oracle/product/11.2.0/db/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
? ? (SID_DESC =
? ? ? (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db)
? ? ? (ORACLE_SID = mydb)
? ? )
)
vi /u01/app/oracle/product/11.2.0/db/network/admin/tnsnames.ora
oradu =
(DESCRIPTION =
? ? (ADDRESS_LIST =
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.150)(PORT = 1521))
? ? )
? ? (CONNECT_DATA =
? ? ? (SERVICE_NAME = oradu)
? ? ? (SERVER = DEDICATED)
? ? )
)
--重启两台机器的监听
lsnrctl stop
lsnrctl start
4、开始复制
--在target db上执行
[oracle@localhost ~]$ rman target / auxiliary sys/123456@oradu
