Duplicating a Database

使用duplicate命令，可以創建一個完全獨立的數據庫拷貝，該命令執行過程中會自動爲duplicated 數據庫分配一個新的dbid。其具體過程我們以同一臺機器內部複製和兩臺機器間的複製分別加以討論

注意：既然是同一臺機器內部複製，那就需考慮爲duplicated 數據庫的控制文件、數據文件、日誌文件尋找新的存儲位置。而兩臺機器間的複製如果爲了省事，可以嘗試保持和源數據相同的目錄結果，或者通過參數設置指定新的存儲位置。

具體過程以linux平臺爲例如下：

一同臺機器內部的複製

1 在源數據庫上生成一個pfile

SQL> create pfile from spfile;

File created.

2 拷貝源庫的pfile 爲目標庫pfile

[oracle@oracle dbs]$ ls -lt

total 12084

-rw-r--r-- 1 oracle oinstall 920 Aug 24 00:54 initCRM.ora

-rw-r----- 1 oracle oinstall 2560 Aug 24 00:52 spfileCRM.ora

-rw-r----- 1 oracle oinstall 10076160 Aug 18 20:36 snapcf_CRM.f

-rw-r----- 1 oracle oinstall 1089536 Aug 14 00:04 02oh7u0i_1_1

-rw-r----- 1 oracle oinstall 1163264 Aug 14 00:04 01oh7u06_1_1

-rw-r----- 1 oracle oinstall 24 Aug 20 2012 lkCRM

-rw-rw---- 1 oracle oinstall 1544 Aug 20 2012 hc_CRM.dat

-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 相關參數

源庫數據文件和日誌文件的位置如下：

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

現打算讓目標庫的數據文件和日誌文件位於/oracle/CRM/下，所以增加下面兩個參數

*.db_file_name_convert=('CRM2','CRM')

*.log_file_name_convert=('CRM2','CRM')

更改前：

CRM.__db_cache_size=268435456

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_retention=1200

*.undo_tablespace='UNDOTBS3'

更改後：

CRMTEST.__db_cache_size=268435456

CRMTEST.__java_pool_size=16777216

CRMTEST.__large_pool_size=16777216

CRMTEST.__oracle_base='/oracle/app'#ORACLE_BASE set from environment

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_retention=1200

*.undo_tablespace='UNDOTBS3'

4 生成目標數據庫的spfile
