關於使用Rman結合netbackup重定向恢復ORACLE資料庫
*****實施環境*****
資料庫伺服器：eagle （原主機）
NBUserver：sol1（NBU備份伺服器）
異機資料庫：sol2（目標主機）
[@more@]
*****恢復的前提條件*****
1、日常資料庫備份成功。至少有一次全備份和Archivelog.
2、原主機的OS及ORACLE版本與目標主機的OS及ORACLE版本保持一致.
3、需要原資料庫、NBUserver的下列資訊：
3.1、IP Address, Hostname, Nbu media server name（NBU備份伺服器） /client name（原主機）
3.2、Oracle DB version,SID,DBID,Datafile Path,Controlfile Path,Archivelog Path
3.3、在目標主機上安裝與原資料庫版本相同的oracle軟體，不建立資料庫。
3.4、在目標主機上安裝NbuClient軟體、DBagent服務，安裝型別與原主機一致。
*********************************各主機軟體安裝情況*********************************
1、資料庫伺服器：eagle （原主機）
oracle9.2.0.6 Server/oracleAgent/NBUClient6.5
2、NBUserver：sol1(NBU備份伺服器)
NBUServer6.5
3、異機資料庫：sol2（目標主機）
oracle9.2.0.6 Server/oracleAgent/NBUClient6.5
*********************************恢復步驟*********************************
目標主機sol2配置
1、安裝NBUClient6.5
1.1、複製帶有NBUClient的65_DVD1_20070723.iso
# ls
65_DVD1_20070723.iso 65_DVD2_20070723.iso
1.2、掛載iso檔案
# lofiadm
Block Device File
# pwd
/opt/nbufile
# lofiadm -a /solairs 10 iso
lofiadm: open: /solairs: No such file or directory
# lofiadm -a /opt/nbufile/65_DVD1_20070723.iso
/dev/lofi/1
#
# mkdir /mnt/iso
# mount -F hsfs /dev/lofi/1 /mnt/iso/
# cd /mnt/iso
# ls

2、安裝NBUClient6.5
2.1、掛載iso

#
3、安裝Oracle 9.2.0.1 升級至 9.2.0.6（此步驟略過）
3.1、將$ORACLE_HOME/dbs/pfile、spfile、pwdfile複製至目標資料庫相同目錄
3.2、根據引數檔案中引數指向的目錄建立，bdump、cump、udump及歸檔路徑
-bash-3.00$mkdir /oracle/app/admin/china111/bdump
-bash-3.00$mkdir /oracle/app/admin/china111/cdump
-bash-3.00$mkdir /oracle/app/admin/china111/udump
-bash-3.00$mkdir /oracle/archive
4、目標主機sol2的nbuClient、hosts檔案配置
4.1、建立$ORACLE_HOME/bp.conf file
#cd $ORACLE_HOME
#vi bp.conf
SERVER = sol1 /*master server name*/
CLIENT_NAME = eagle /*source host name*/
CLINET_READ_TIMEOUT = 1800
4.2、編輯/usr/openv/netbackup/bp.conf
#vi bp.conf
SERVER = sol1 /*master server name*/
CLIENT_NAME = eagle /*source host name*/
CLIENT_NAME = sol2 /*target host name */
VERBOSE = 5
CLIENT_READ_TIMEOUT = 1800
CLIENT_CONNECT_TIMEOUT = 1800
4.3 編輯/etc/hosts檔案
#vi /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
192.168.45.12 sol2 loghost sol2.company.igocctv.com.
192.168.45.11 sol1
192.168.43.180 autosvr
#AD Use
192.168.45.10 company.igocctv.com
5、NBUserver主機的nbu、hosts檔案配置
5.1、建立檔案允許進行重定向恢復主機
#cd /usr/openv/netbackup/db/altnames
#touch sol2 /*target host name */
#cd /usr/openv/netbackup/db/altnames
#touch No.Restrictions
5.2、編輯/etc/hosts檔案
#vi /etc/hosts
# vi /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
192.168.45.11 sol1 loghost sol1.company.igocctv.com.
192.168.45.12 sol2
192.168.43.101 swallow1
192.168.43.102 swallow2
192.168.43.151 swallow3
192.168.43.152 swallow4
192.168.43.180 autosvr
192.168.43.2 eagle
6、開始恢復資料庫
6.1、使用pfile或spfile在目標主機（sol2）上啟動資料庫到nomount 狀態

6.2、rman恢復資料庫
首先在NBUserver端找到有效的備份檔案，其中/cntrl_2602_1_753766268為最新的控制檔案
