同一台主机使用RMAN的duplicate复制数据库，【RMAN】使用duplicate本地复制数据库操作系统中有一套正在运行的数据库enmoedu 复制后的数据库aux

任务：同一台主机使用RMAN的duplicate复制数据库，【RMAN】使用duplicate本地复制数据库操作系统中有一套正在运行的数据库enmoedu 复制后的数据库aux

实验步骤：

1. 主库RMAN备份

[Oracle@test ~]$ export ORACLE_SID=enmoedu

[oracle@test ~]$ rman target /

2. 配置监听文件及tnsnames.ora

--监听改静态 listener.ora 因为复制的aux库是nomount状态，pmon是mount的时候去动态注册，所以需要加静态注册。

Listener.ora文件修改后：

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = enmoedu)

(ORACLE_HOME = /11g/app/oracle/product/11.2.0/dbhome)

(SID_NAME = enmoedu)

)

(SID_DESC =

(GLOBAL_DBNAME = aux)

(ORACLE_HOME = /11g/app/oracle/product/11.2.0/dbhome)

(SID_NAME = aux)

)

)

Tnsnames.ora文件中添加：

aux =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.8)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = aux)

)

)

3. 通过enmoedu库的SPFILE生成PFILE，复制PFILE文件，，将SID名字更改为aux，并且将文件中参数进行修改。
