RMAN duplicate database
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.

Fixed Size 1336232 bytes
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 /
