使用duplicate命令，可以创建一个完全独立的数据库拷贝，该命令执行过程中会自动为duplicated 数据库分配一个新的dbid。其具体过程我们以同一台机器内部复制和两台机器间的复制分别加以讨论
注意：既然是同一台机器内部复制，那就需考虑为duplicated 数据库的控制文件、数据文件、日志文件寻找新的存储位置。而两台机器间的复制如果为了省事，可以尝试保持和源数据相同的目录结果，或者通过参数设置指定新的存储位置。
具体过程以linux平台为例如下：
一 同台机器内部的复制
1 在源数据库上生成一个pfile
SQL> create pfile from spfile;
File created.
2 拷贝源库的pfile 为目标库pfile
[oracle@oracle dbs]$ ls -lt
total 12084

-rw-r--r-- 1 oracle oinstall 2851 May 15 2009 init.ora
[oracle@oracle dbs]$ cp initCRM.ora initCRMTEST.ora
3 更改initCRMTEST.ora 相关参数
源库数据文件和日志文件的位置如下：
SQL> select name from v$datafile;
NAME
--------------------------------------------------
/oracle/CRM2/system01.dbf
/oracle/CRM2/sysaux01.dbf
/oracle/CRM2/zx.dbf
/oracle/CRM2/users01.dbf
/oracle/CRM2/pos.dbf
/oracle/CRM2/erp.dbf
/oracle/CRM2/user01.dbf
/oracle/CRM2/undotbs03.dbf
SQL> select group#,member from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------
4 /oracle/CRM2/redo02.dbf
3 /oracle/CRM2/redo03.log
2 /oracle/CRM2/redo02.log
1 /oracle/CRM2/redo01.log
现打算让目标库的数据文件和日志文件位于/oracle/CRM/下，所以增加下面两个参数
*.db_file_name_convert=('CRM2','CRM')
*.log_file_name_convert=('CRM2','CRM')
更改前：
