使用rman本机复制新数据库
使用rman復制數據庫
原數據庫sid orcl ?復制新的數據庫sid為 nylg
1.創建復制備份數據庫的參數文件
在原數據庫創建pfile
create pfile from spfile;
然后復制pfile參數文件
[oracle@Nagiostest dbs]$ pwd
/u01/app/oracle/product/11.2/dbs
[oracle@Nagiostest dbs]$ cp initorcl.ora initnylg.ora?
修改orcl數據庫名改為nylg
vi initnylg.ora 修改如下：
:%s/orcl/nylg/g
在這里注意，修改參數文件后，在最后行添加兩行轉換參數，指定新數據文件存放路徑
db_file_name_convert = ('/u01/app/oracle/oradata/orcl','/u01/app/oracle/oradata/nylg')
log_file_name_convert = ('/u01/app/oracle/oradata/orcl','/u01/app/oracle/oradata/nylg')
2.創建相對應的目錄，啟動復制數據庫的輔助實例
mkdir -p $ORACLE_BASE/admin/nylg/{a,b,c,u}dump
mkdir -p /u01/app/oracle/oradata/nylg
orapwd file=$ORACLE_HOME/dbs/orapwnylg password=yuanlei force=y
[oracle@Nagiostest ~]$ export ORACLE_SID=nylg
使用pfile啟動輔助實例到nomount
startup nomount pfile=?/dbs/initnylg.ora ??
如下：
[oracle@Nagiostest ~]$ export ORACLE_SID=nylg
[oracle@Nagiostest ~]$ sqlplus /nolog

SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup nomount pfile=?/dbs/initnylg.ora
ORACLE instance started.

Fixed Size ? ?2213896 bytes
Variable Size ?314574840 bytes
Database Buffers ? 92274688 bytes
Redo Buffers ? ?4308992 bytes
3.在新的會話中（ORACLE_SID=orcl）對原數據庫做rman全備
export ORACLE_SID=orcl
rman target /
run {
sql 'alter system archive log current';
backup database format='/u01/rmanbak/%d_%s.dbf'
plus archivelog format='/u01/rmanbak/%d_%s.arc';
sql 'alter system archive log current';
}
4.配置復制庫監聽（就是本機的監聽文件），服務名采用靜態注冊，啟動監聽，這步很重要
不要有錯誤
[oracle@Nagiostest admin]$ vim listener.ora?
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
? (SID_LIST =
? ? (SID_DESC =
? ? ? (SID_NAME = PLSExtProc)
? ? ? (ORACLE_HOME = /u01/app/oracle/product/11.2)
? ? ? (PROGRAM = extproc)
? ? )
? ? (SID_DESC =
? ? ? (SID_NAME = nylg)
? ? ? (ORACLE_HOME = /u01/app/oracle/product/11.2)
? ? ? (GLOBAL_DBNAME = NYLG)
? ? )
? )
ADR_BASE_LISTENER = /u01/app/oracle
[oracle@Nagiostest admin]$ vim tnsnames.ora?
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
NYLG =
? (DESCRIPTION =
? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.210)(PORT = 1521))
? ? (CONNECT_DATA =
? ? ? (SERVER = DEDICATED)
? ? ? (SERVICE_NAME = nylg)
? ? )
? )
lsnrctl start
5.用rman連接到主庫實例和輔助實例，運行復制命令
[oracle@Nagiostest dbs]$ rman target /
Recovery Manager: Release 11.2.0.1.0 - Production on Wed Aug 13 11:01:56 2014

connected to target database: ORCL (DBID=1382226447)
RMAN> connect auxiliary sys/yuanlei@nylg
connected to auxiliary database: NYLG (not mounted)
這里如果遇到
RMAN-04006: error from auxiliary database: ORA-01031: insufficient privileges
請檢查你的監聽配置和口令文件是否正確，一般就這兩個原因（我做的時候是把監聽sid大寫小弄錯）
然后繼續
RMAN> duplicate target database to nylg;
其它配置沒問題話的，這里等一會就完成了
Starting Duplicate Db at 2014/08/13 11:02:38
using target database control file instead of recovery catalog

contents of Memory Script:
{
? ?Alter clone database open resetlogs;
}
executing Memory Script

Finished Duplicate Db at 2014/08/13 11:07:26
此時新的數據庫已經處于open狀態了！
[oracle@Nagiostest ~]$ echo $ORACLE_SID
nylg
[oracle@Nagiostest ~]$ sqlplus / as sysdba
