快速拉起是NBU 8 的新功能，利用Oracle RMAN的 image copy（NBU 7是透過RMAN傳統備份集——BackupSet的方式）做的物理檔案的映象副本，利用NFS直接掛載到恢復機上，無需手動“restore database”從而達到快速恢復資料庫的目的；並且在備份方面（增量備份）只備份更改過的資料塊，更加節省空間（需要開啟Oracle塊跟蹤： alter database enable block change tracking ）。

實驗環境

OS ：Oracle Linux 6.10

DataBase ：Oracle 11.2.0.4

NBU ：8.2

注：資料庫備份在NBU服務端（Master），恢復在NBU客戶端（Client）；RAC和單機的恢復方式相同，但RAC只需要在某一個節點上備份。

NBU Master 端操作

1 、登入Master伺服器：

為了驗證Master的NFS配置是否成功，先在Client用bplist查詢備份映象能否識別，能夠正常列出備份映象證明配置生效

/usr/openv/netbackup/bin/bplist -C TestDB -t 4 -R -l /

2 、在Master查詢能夠即時拉起的映象image，根據“Time”選擇想要恢復的日期，並記錄下ID（紅色標記部分）

[root@NBUMaster ~]# nborair -list_images -client TestDB -server NBUMaster

Time: 2020-12-20 08:20:51 ID: TestDB_1608409301 Full Backup testdb

Time: 2020-12-21 08:16:29 ID: TestDB_ 1608495368 Full Backup testdb

注意：

（1）命令內-client指源機的主機名，-server指Master的主機名

（2）下面的“Full Backup”字樣只是人為定義的tag名稱，不代表“全庫備份”

3 、確認所需映象image包含的檔案

[root@NBUMaster ~]# nborair -list_files -backupid TestDB_1608495368 （檢查表空間的備份是否都存在）

-rw-r----- oracle asmadmin 33554424K 12 月 21 08:12 /nfspool/data_D-TEST_I-1979817751_TS_UNDOTBS1_testdb02

-rw-r----- oracle asmadmin 33554424K 12 月 21 08:12 /nfspool/data_D-TEST_I-1979817751_TS_USERS_testdb02

......

4 、基於ID生成映象快照，以便異機恢復掛載。

注意：命令內-dest_client後跟異機的主機名hostname

[root@NBUMaster ~]# nborair -create_recovery_point -backupid TestDB_1608495368 -dest_client NBU82Restore

如果此步報錯：

[root@NBUMaster ~]# nborair -create_recovery_point -backupid TestDB_1608495368 -dest_client NBU82Restore

Error message from Appliance : Failed to reexport NFS shares (UMI Code : V-409-500-1042)

EXIT STATUS 5432: The requested NetBackup appliance operation is unsuccessful.

[root@NBUMaster ~]# nborair -create_recovery_point -backupid TestDB_1608495368 -dest_client NBU82Restore

Error message from Appliance : Recovery point already exists. Export path: /shares/test_nfspool_TestDB_1608495368_

rp1, Export options: nbu82restore(rw,no_root_squash,insecure), Appliance : NBUMedia01. (UMI Code : V-409-500-1002)EXIT STATUS 5432: The requested NetBackup appliance operation is unsuccessful.

如果報以上提示說明建立恢復點失敗

列出當前 mediaserver 上掛載的所有掛載點：

[root@NBUMaster ~]# nborair -list_recovery_points -appliance NBUMedia01

Total 2 recovery points found.

Export path: /shares/test_nfspool_TestDB_1595091960_rp1

Share name: nbutest_nfspool

Export options: nbu82restore(rw,no_root_squash,insecure)

Export path: /shares/test_nfspool_TestDB_1608495368_rp1

Share name: nbutest_nfspool

Export options: nbu82restore(rw,no_root_squash,insecure)

刪除剛才 建立失敗的掛載點：

[root@NBUMaster ~]# nborair -delete_recovery_point -appliance NBUMedia01 -export_path /shares/test_nfspool_TestDB_1608495368_rp1

然後再次檢視掛載點是否還在。

5 、在Oracle客戶端（200.0.253.127）上建立掛載點：

[root@NBU82Restore ~]# mkdir /nfspool

NBU Client 端掛載操作

1 、用root使用者掛載VA Media一體機提供的NFS Shares空間，掛載引數如下：

# mount -t nfs NBUMedia01.local:/shares/test_nfspool_TestDB_1595091960_rp1 -o rw,bg,hard, nolock,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=3,timeo=600 /nfspool

2 、改Oracle客戶端掛載點nfspool的許可權：

# chmod 700 /nfspool

# chown -R oracle:oinstall /nfspool ——必須設定成oracle許可權

3 、oracle客戶端配置oracle_link，切換到oracle使用者做oracle_link（需先設定對應資料庫的SID）

# /usr/openv/netbackup/bin/oracle_link

4、執行恢復

4.1 啟動資料庫到nomount狀態，設定原機的DBID

[oracle@NBU82Restore ~]$ rman target /

RMAN> set DBID=1979817751

RMAN> startup nomount;

4.2 恢復spfile：

RMAN> restore spfile to '/nfspool/spfiletmp.ora' from '/nfspool/spfile_D-TEST_I-1979817751_T-20201221_cfvijqbi_testdb02';

Starting restore at 21-DEC-20

using channel ORA_DISK_1

channel ORA_DISK_1: restoring spfile from AUTOBACKUP /nfspool/spfile_D-TEST_I-1979817751_T-20201221_cfvijqbi_testdb02

channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete

Finished restore at 21-DEC-20

RMAN> exit

4.3 退出RMAN，進入SQL建立pfile

SQL> create pfile='/nfspool/pfile.ora' from spfile='/nfspool/spfiletmp.ora';

File created.

4.4 進入RMAN，恢復控制檔案

RMAN> restore controlfile to '/nfspool/control01.ctl' from '/nfspool/cf_D-TEST_I-1979817751_T-20201221_cgvijqbj_testdb02';

注：需修改步驟3中pfile.ora 引數：

*.control_files='/nfspool/control01.ctl'

*.log_archive_dest_1='LOCATION=/nfspool'

4.5 從新建立的pfile啟動到mount狀態

[oracle@NBU82Restore ~]$ export ORACLE_SID=test

[oracle@NBU82Restore ~]$ sqlplus / as sysdba

注：最後 recover 的報錯屬於正常現象，已經預設把所有可以找到的歸檔應用了（相當於 until cancel ）

4.8 修改onlinelog路徑為NFS共享池

在生產系統上執行以下語句獲取系統redo日誌：

select 'alter database rename file '''||member||''' to ''/nfspool/redo001.log'';' from v$logfile;

注：rename 後的log 名字要更改為不同的名字

alter database rename file '+DATA/test/onlinelog/group_1.257.1043835675' to '/nfspool/redo001.log';

alter database rename file '+DATA/test/onlinelog/group_2.258.1043835677' to '/nfspool/redo002.log';

alter database rename file '+DATA/test/onlinelog/group_3.259.1043835677' to '/nfspool/redo003.log';

alter database rename file '+DATA/test/onlinelog/group_4.260.1043835679' to '/nfspool/redo004.log';

alter database rename file '+DATA/test/onlinelog/group_5.261.1043835681' to '/nfspool/redo005.log';

alter database rename file '+DATA/test/onlinelog/group_6.262.1043835683' to '/nfspool/redo006.log';

alter database rename file '+DATA/test/onlinelog/group_7.263.1043835683' to '/nfspool/redo007.log';

alter database rename file '+DATA/test/onlinelog/group_8.264.1043835685' to '/nfspool/redo008.log';

alter database rename file '+DATA/test/onlinelog/group_101.284.1045059565' to '/nfspool/redo009.log';

alter database rename file '+DATA/test/onlinelog/group_102.285.1045059567' to '/nfspool/redo010.log';

alter database rename file '+DATA/test/onlinelog/group_103.286.1045059569' to '/nfspool/redo011.log';

alter database rename file '+DATA/test/onlinelog/group_104.287.1045059571' to '/nfspool/redo012.log';

alter database rename file '+DATA/test/onlinelog/group_105.288.1045059571' to '/nfspool/redo013.log';

alter database rename file '+DATA/test/onlinelog/group_106.289.1045059573' to '/nfspool/redo014.log';

alter database rename file '+DATA/test/onlinelog/group_107.290.1045059575' to '/nfspool/redo015.log';

alter database rename file '+DATA/test/onlinelog/group_108.291.1045059577' to '/nfspool/redo016.log';

alter database rename file '+DATA/test/onlinelog/group_109.292.1045059577' to '/nfspool/redo017.log';

另，如果搭建過DG，可以刪除standby log：

SQL> select group# from v$standby_log;

GROUP#

----------

101

102

103

104

105

106

107

108

109

9 rows selected.

SQL> select 'alter database drop standby logfile group '||group#||';' from v$standby_log;

'ALTERDATABASEDROPSTANDBYLOGFILEGROUP'||GROUP#||';'

--------------------------------------------------------------------------------

alter database drop standby logfile group 101;

alter database drop standby logfile group 102;

alter database drop standby logfile group 103;

alter database drop standby logfile group 104;

alter database drop standby logfile group 105;

alter database drop standby logfile group 106;

alter database drop standby logfile group 107;

alter database drop standby logfile group 108;

alter database drop standby logfile group 109;

9 rows selected.

4.9 開啟資料庫

SQL> alter database disable block change tracking; -- 關閉塊跟蹤

Database altered.

SQL> alter database open resetlogs;

Database altered.

SQL> select open_mode from v$database;

OPEN_MODE

----------------------------------------

READ WRITE

注：

SQL> alter database open resetlogs; ——如果此步報錯

alter database open resetlogs

*

ERROR at line 1:

ORA-00392: log 5 of thread 1 is being cleared, operation not allowed

ORA-00312: online log 5 thread 1: '/nfsbta/redo005.log'

ORA-00312: online log 5 thread 1: '/nfsbta/redo055.log'

執行： alter database clear logfile group 5;

再 alter database open resetlogs; ——再報錯繼續 clear
