任务：同一台主机使用RMAN的duplicate复制数据库，linux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。
