1. 為輔助資料庫建立目錄結構

mkdir /u01/app/oracle/oradata/dupdb

mkdir /u01/app/oracle/admin/dupdb

mkdir /u01/app/oracle/admin/dupdb/adump

mkdir /u01/app/oracle/flash_recovery_area/dupdb

2. 從ORCL資料庫生成pfile引數檔案，並進行復制、修改建立出輔助資料庫的引數檔案

從source db(orcl)生成pfile：

SQL> create pfile from spfile;

File created.

複製pfile並做相應修改：

[oracle@ora10g oracle]$ cd $ORACLE_HOME/dbs

[oracle@ora10g dbs]$ cp initorcl.ora initdupdb.ora

修改initdupdb.ora內容：

vi initdupdb.ora

*.audit_file_dest='/u01/app/oracle/admin/dupdb/adump'

*.control_files='/u01/app/oracle/oradata/dupdb/control01.ctl','/u01/app/oracle/flash_recovery_area/dupdb/control02.ctl'

*.db_name='dupdb'

*.db_file_name_convert='/u01/app/oracle/oradata/orcl','/u01/app/oracle/oradata/dupdb'

*.log_file_name_convert='/u01/app/oracle/oradata/orcl','/u01/app/oracle/oradata/dupdb'

3. 啟動輔助資料庫例項startup nomount duplicate db dupdb

[oracle@ora10g dbs]$ export ORACLE_SID=dupdb

[oracle@ora10g dupdb]$ sqlplus "/ as sysdba"

SQL> startup force nomount pfile=/u01/app/oracle/product/11.2.0/db_1/dbs/initdupdb.ora

ORACLE instance started.

Variable Size 205524056 bytes

Database Buffers 100663296 bytes

Redo Buffers 6336512 bytes

4. 為輔助資料庫建立口令檔案

[oracle@ora10g dbs]$ export ORACLE_SID=dupdb

[oracle@ora10g dbs]$ orapwd file=/u01/app/oracle/product/11.2.0/db_1/dbs/orapwdupdb password=oracjle entries=5 force=y

5. 編輯tnsnames.ora檔案，增加下列服務連線別名

[oracle@ora10g admin]$ vi $ORACLE_HOME/network/admin/tnsnames.ora

ORCL =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = ORCL)

)

DUPDB =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = DUPDB)

)

6. 編輯監聽器配置檔案listener.ora, 啟動監聽器

[oracle@ora10g ~]$ vi $ORACLE_HOME/network/admin/listener.ora

LISTENER =

(DESCRIPTION =

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

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = orcl)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

)

(SID_DESC =

(SID_NAME = dupdb)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

)

[oracle@ora10g ~]$ lsnrctl start

7. 備份還原資料庫orcl

[oracle@ora10g admin]$ export ORACLE_SID=orcl

[oracle@ora10g admin]$ rman target /

Recovery Manager: Release 11.2.0.1.0 - Production on Fri Mar 29 12:56:24 2013

8. 開始RMAN duplicate複製
