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

IA64 NB_65_ICS_1.4.37.3_WIN32 X86 x64

Launch.bat NB_65_ICS_1.4.37.3_WINIA64 autorun.inf

NBClients NB_65_ICS_1.4.37.3_WINX64 install

#

1.3、開始安裝NBUClient

# ./install

#

2、安裝NBUClient6.5

2.1、掛載iso

# ls

65_DVD1_20070723.iso 65_DVD2_20070723.iso 65_DVD4_20070723.iso

#

2.2、安裝NetBackup Database Agent Software

# ./install

Symantec Installation Script

Installation Options

1 NetBackup Add-On Product Software

2 NetBackup Database Agent Software

q To quit from this script

#

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

# su - oracle

Sun Microsystems Inc. SunOS 5.10 Generic January 2005

-bash-3.00$ ORACLE_SID=china111

-bash-3.00$ sqlplus " / as sysdba "

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

# bplist -C eagle -S sol1 -l -t 4 -s 6/13/2011 -e 6/14/2011 -R /
