本實例測試ORACLE 11g使用rman復(fù)制數(shù)據(jù)庫。11g的RMAN duplicate 可以通過Active database duplicate和Backup-based duplicate兩種方法實現(xiàn)。這里的測試使用的是Backup-based duplicate。
10年的安丘網(wǎng)站建設(shè)經(jīng)驗,針對設(shè)計、前端、開發(fā)、售后、文案、推廣等六對一服務(wù),響應(yīng)快,48小時及時工作處理。全網(wǎng)營銷推廣的優(yōu)勢是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同,自動調(diào)整安丘建站的顯示方式,使網(wǎng)站能夠適用不同顯示終端,在瀏覽器中調(diào)整網(wǎng)站的寬度,無論在任何一種瀏覽器上瀏覽網(wǎng)站,都能展現(xiàn)優(yōu)雅布局與設(shè)計,從而大程度地提升瀏覽體驗。創(chuàng)新互聯(lián)從事“安丘網(wǎng)站設(shè)計”,“安丘網(wǎng)站推廣”以來,每個客戶項目都認(rèn)真落實執(zhí)行。

實驗環(huán)境:
target db:
ip 192.168.56.10

oracle_version=11.2.0.3
auxiliary db:
ip 192.168.56.150
oracle_sid=oradu
oracle_version=11.2.0.3

2、復(fù)制參數(shù)文件和創(chuàng)建密碼文件
--必須保持target DB和auxiliary DB的密碼一致。這里我直接把target db的密碼文件復(fù)制到auxiliary db對應(yīng)的目錄下
--target db上執(zhí)行
[oracle@localhost ~]$ cd $ORACLE_HOME/dbs
[oracle@localhost dbs]$ scp orapwmydb oracle@192.168.56.150:/home/oracle
oracle@192.168.56.150's password:
orapwmydb 100% 1536 1.5KB/s 00:00
[oracle@localhost dbs]$ scp initmydb.ora oracle@192.168.56.150:/home/oracle
oracle@192.168.56.150's password:
initmydb.ora 100% 193 0.2KB/s 00:00
3、把舊機(jī)器的備份復(fù)制到新機(jī)器上的對應(yīng)目錄
[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/34r0vd8l_1_1 oracle@192.168.56.150:/home/oracle/bak
oracle@192.168.56.150's password:
34r0vd8l_1_1 100% 5457KB 5.3MB/s 00:00
[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/35r0vd8m_1_1 oracle@192.168.56.150:/home/oracle/bak
oracle@192.168.56.150's password:
35r0vd8m_1_1 100% 1049MB 15.0MB/s 01:10
[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/36r0vdad_1_1 oracle@192.168.56.150:/home/oracle/bak
oracle@192.168.56.150's password:
36r0vdad_1_1 100% 9952KB 9.7MB/s 00:00
[oracle@localhost dbs]$ scp /u01/app/oracle/product/11.2.0/db/dbs/37r0vdag_1_1 oracle@192.168.56.150:/home/oracle/bak
oracle@192.168.56.150's password:
37r0vdag_1_1 100% 10KB 10.0KB/s 00:00
4、更改密碼文件、參數(shù)文件的文件名和參數(shù)文件中的對應(yīng)的實例名(實例名不變時不需要執(zhí)行),
把目錄轉(zhuǎn)換參數(shù)加入?yún)?shù)文件中(實例名、目錄不變時不需要)
本實驗中更新實例名為oradu
[oracle@localhost ~]$ mv initmydb.ora initoradu.ora
[oracle@localhost ~]$ mv orapwmydb orapworadu
vi initoradu.ora把所有的舊實例名mydb改為oradu,并加入轉(zhuǎn)換參數(shù)
db_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')
log_file_name_convert=('/u01/app/oracle/oradata/mydb/','/u01/app/oracle/oradata/oradu/')
新建目錄
mkdir -p /u01/app/oracle/oradata/oradu/
不改變實例名只需要新建目錄
mkdir -p /u01/app/oracle/oradata/mydb/
移動參數(shù)文件和密碼文件到默認(rèn)目錄中/u01/app/oracle/product/11.2.0/db/dbs/
[oracle@localhost ~]$ mv initoradu.ora /u01/app/oracle/product/11.2.0/db/dbs/
[oracle@localhost ~]$ mv orapworadu /u01/app/oracle/product/11.2.0/db/dbs/
5、啟動到nomount
[oracle@localhost ~]$ export ORACLE_SID=oradu
[oracle@localhost ~]$ sqlplus / as sysdba
