rman增量備份腳本
Oracle資料庫RMAN的自動備份腳本簡介
各位同學知道Oracle資料庫RMAN如何自動備份腳本嘛?下面我為大家整理了關於Oracle資料庫RMAN的自動備份腳本文章，希望能為你提供幫助：
1、資料庫設置為歸檔方式
2、資料庫的備份腳本
db_full_backup.sh ：資料庫全備腳本
db_l0_backup.sh ：資料庫0級備份腳本
db_l1_backup.sh ：資料庫1級備份腳本
ftp_del.sh ：數據FTP清理腳本
rman_bak.sh ：數據備份主程序
3、備份原理
每周1、3、6進行0級備份
每周日、2、4、5進行1級備份
備份文件上傳到FTP伺服器
FTP伺服器每周清理一次，但是清理後將周六和周日的備份進行保留(6.bak和0.bak)
所有工作防暑crontab中自動執行備份
4、備份目錄含義
arc ：資料庫歸檔目錄
rmanbak ：資料庫備份文件的保存目錄
rmanscripts ：資料庫腳本存放路徑
5、FTP目錄
ftp上必須手動建立目錄
L0：

『貳』 oracle資料庫這樣的（照片所示）rman備份腳本怎麼寫
只考慮備份，不考慮其他情況下：
root下的3個rman備份級別的腳本：
#cat rman_0.sql
backup incremental level 0 database;
#cat rman_1.sql
backup incremental level 1 database;
#cat rman_1c.sql
backup incremental level 1 cumulative database;
root下的調用rman腳本
#cat rman_0.sh
#!/bin/bash
su - oracle -c "rman target sys/SHUIMITAO@rabbit @/root/rman_0.sql"
#cat rman_1.sh
#!/bin/bash
su - oracle -c "rman target sys/SHUIMITAO@rabbit @/root/rman_1.sql"
#cat rman_1c.sh
#!/bin/bash
su - oracle -c "rman target sys/SHUIMITAO@rabbit @/root/rman_1c.sql"
root的計劃任務：
#crontab -e
0 1 * * 0 /root/rman_0.sh
0 2 * * 1 /root/rman_1.sh
0 2 * * 2 /root/rman_1.sh
0 3 * * 3 /root/rman_1c.sh
0 2 * * 4 /root/rman_1.sh
0 3 * * 5 /root/rman_1c.sh
0 2 * * 6 /root/rman_1.sh
11g里只有0和1兩個備份級別，請自行對應oracle低版本
level 0是full
level 1是差異增量備份 --和前一次備份比較，將這個期間改變的數據備份下來
level 1c是累計增量備份 --和比他小得級別相比（即全備份），改變的數據備份
然後根據實際情況還要將備份的策略往腳本添加

『伍』 oracle rman備份腳本怎麼寫
在ORACLE資料庫中，RMAN備份的腳本非常多，下面介紹一例shell腳本如何通過RMAN備份，以及FTP上傳RMAN備份文件以及歸檔日誌文件的腳本。
fullback.sh 裡面調用RMAN命令做資料庫備份，它使用的cmdfile為/home/oracle/backup/bin/fullback.rcv，同時在/home/oracle/backup/logs目錄下生成日誌文件。
1: [oracle@DB-Server bin]$ more fullback.sh
2:
3: #!/bin/bash
4:
5: export ORACLE_BASE=/u01/app/oracle
6:
7: export ORACLE_SID=gps
8:
9: ORACLE_HOME=$ORACLE_BASE/proct/10.2.0/db_1; export ORACLE_HOME
10:
11: TMP=/tmp; export TMP
12:
13: TMPDIR=$TMP; export TMPDIR
14:
15: PATH=/usr/sbin:$PATH; export PATH
16:
17: PATH=$ORACLE_HOME/bin:$PATH; export PATH
18:
19: LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
20:
21: CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;
22:
23: export CLASSPATH
24:
25: TODAY=`date +%Y_%m_%d`
26:
27: rman nocatalog target / cmdfile /home/oracle/backup/bin/fullback.rcv log /home/oracle/backup/logs/fullbackup_$TODAY.log
28:
29: /home/oracle/backup/bin/ftpbackup.sh
30:
fullback.rcv文件非常簡單， 如下所示：
1: [oracle@DB-Server bin]$ more /home/oracle/backup/bin/fullback.rcv
2:
3: run{
4:
5: allocate channel c4 type disk;
6:
7: backup as compressed backupset
8:
9: skip inaccessible
10:
11: tag fullbackupwitharchivelog
12:
13: (database);
14:
15: backup current controlfile;
16:
17: backup spfile;
18:
19: sql "alter system archive log current";
20:
21: delete noprompt obsolete;
22:
23: release channel c4;
24:
25: }
26:
RMAN生成的備份文件，需要通過FTP上傳到FTP伺服器，一則資料庫伺服器沒有這么多空間存儲多天的備份，二則是出於容災、數據安全需要。
下面腳本中FTP伺服器，用戶名密碼均使用xxx替代，在實際環境中，使用具體的信息替代即可。
1: [oracle@DB-Server bin]$ more ftpbackup.sh
2:
3: #!/bin/sh、
4:
5: rm -f /home/oracle/.netrc
6:
7: date_yesterday=`date -d'yesterday' +%Y_%m_%d`
8:
9: date_today=`date +%Y_%m_%d`
10:
11: echo "default login xxxx password xxxxxx" >> /home/oracle/.netrc
12:
13: echo "macdef init" >> /home/oracle/.netrc
14:
15: echo "binary" >> /home/oracle/.netrc
16:
17: echo "cd archivelog" >> /home/oracle/.netrc
18:
19: echo "mkdir $date_yesterday" >> /home/oracle/.netrc
20:
21: echo "cd $date_yesterday" >> /home/oracle/.netrc
22:
23: echo "lcd /u04/flash_recovery_area/gps/archivelog/$date_yesterday" >> /home/oracle/.netrc
24:
25: echo "mput *" >> /home/oracle/.netrc
26:
27: echo "cd .." >> /home/oracle/.netrc
28:
29: echo "mkdir $date_today" >>/home/oracle/.netrc
30:
31: echo "cd $date_today" >>/home/oracle/.netrc
32:
33: echo "lcd /u04/flash_recovery_area/gps/archivelog/$date_today" >>/home/oracle/.netrc
34:
35: echo "mput * ">>/home/oracle/.netrc
36:
37: echo "cd .." >>/home/oracle/.netrc
38:
39: echo "cd ../backupset" >> /home/oracle/.netrc
40:
41: echo "mkdir $date_today" >> /home/oracle/.netrc
42:
43: echo "cd $date_today" >> /home/oracle/.netrc
44:
45: echo "lcd /u04/flash_recovery_area/gps/backupset/$date_today" >> /home/oracle/.netrc
46:
47: echo "mput *" >> /home/oracle/.netrc
48:
49: echo "cd .." >> /home/oracle/.netrc
50:
51: echo "cd ../autobackup" >> /home/oracle/.netrc
52:
53: echo "mkdir $date_today" >> /home/oracle/.netrc
54:
55: echo "cd $date_today" >> /home/oracle/.netrc
56:
57: echo "lcd /u04/flash_recovery_area/gps/autobackup/$date_today" >> /home/oracle/.netrc
58:
59: echo "mput *" >> /home/oracle/.netrc
60:
61: echo "quit" >> /home/oracle/.netrc
62:
63: echo "" >> /home/oracle/.netrc
64:
65: chmod 600 /home/oracle/.netrc
66:
67: ftp -i -v xxx.xxx.xxx.xxx 8021 >>/home/oracle/backup/logs/ftp$date_today.log 2>&1
68:
另外，關於歸檔日誌也需要每隔2小時上傳一次到FTP伺服器，2小時上傳一次歸檔日誌的shell腳本如下所示：
1: [oracle@DB-Server bin]$ more ftp2hours.sh
2:
3: #!/bin/sh
4:
5: rm -f /home/oracle/.netrc
6:
7: date_yesterday=`date -d'yesterday' +%Y_%m_%d`
8:
9: date_today=`date +%Y_%m_%d`
10:
11: echo "default login xxxx password xxxx" >> /home/oracle/.netrc
12:
13: echo "macdef init" >> /home/oracle/.netrc
14:
15: echo "binary" >> /home/oracle/.netrc
16:
17: echo "cd archivelog" >> /home/oracle/.netrc
18:
19: echo "mkdir $date_today" >>/home/oracle/.netrc
20:
21: echo "cd $date_today" >>/home/oracle/.netrc
22:
23: echo "lcd /u04/flash_recovery_area/gps/archivelog/$date_today" >>/home/oracle/.netrc
24:
25: echo "mput * ">>/home/oracle/.netrc
26:
27: echo "quit" >> /home/oracle/.netrc
28:
29: echo "" >> /home/oracle/.netrc
30:
31: chmod 600 /home/oracle/.netrc
32:
33: ftp -i -v xxx.xxx.xxx.xxx 8021 >>/home/oracle/backup/logs/ftp2hours.$date_today.log 2>&1
34:
最後需要將RMAN備份生成的日誌文件，以及FTP上傳備份文件以及歸檔日誌的記錄通過郵件形式發送給DBA或系統管理員，
1: [oracle@DB-Server bin]$ more chkbackandmail.sh
2: #!/bin/bash
3: rm -f /home/oracle/backup/bin/sendmail.pl
4: date_today=`date +%Y_%m_%d`
5: subject="Oracle Backup Alert Service on $date_today"
6: content="Dear colleagues,
7:
8: Attached please find the logs of xxx(xxx.xxx.xxx.xxx) oracle database backup and transfer to FTP Server(xxx.xxx.xxx.xxx), please
9: review the file and check whether the backup succeeded or not,and double check all backups have been mped to tape, many tha
10: nks
11:
12:
13:
14:
15: Best regards
16: Oracle Alert Services
17:
18: "
19: file="/home/oracle/backup/logs/fullbackup_$date_today.log,/home/oracle/backup/logs/ftp$date_today.log"
20: echo "#!/usr/bin/perl" >> /home/oracle/backup/bin/sendmail.pl
21: echo "use Mail::Sender;" >> /home/oracle/backup/bin/sendmail.pl
22: echo "\$sender = new Mail::Sender {smtp => 'xxx.xxx.xxx.xxx', from => '[email protected]'}; ">> /home/oracle/backup/bin/sendmai
23: l.pl
24: echo "\$sender->MailFile({to => '[email protected]',">> /home/oracle/backup/bin/sendmail.pl
25: echo "cc=>'[email protected],[email protected],[email protected]'," >> /home/oracle/backup/b
26: in/sendmail.pl
27: echo "subject => '$subject',">> /home/oracle/backup/bin/sendmail.pl
28: echo "msg => '$content',">> /home/oracle/backup/bin/sendmail.pl
29: echo "file => '$file'});">> /home/oracle/backup/bin/sendmail.pl
30: perl /home/oracle/backup/bin/sendmail.pl
最後在Crontab 作業裡面配置調用這些shell腳本。例如如下所示，在1：01分執行fullback.sh ，每隔兩個小時（例如0:50、2:50...)執行一次ftp2hours.sh, 在每天早上8:40執行chkbackandmail.sh 發送fullback.sh 以及ftp2hour.sh的執行日誌記錄。
『陸』 oracle怎麼用rman腳本進行備份
Oracle資料庫中rman備份腳本非常實用
查詢字元集
SQL> select * from nls_database_parameters;
NLS_CHARACTERSET
AL32UTF8
備份時字元集很重要，不然會出亂碼
一、0級備份（全備）紅色是要修改的，根據個人的存放位置。
[oracle@oracle122 script]$ cat db_bak0.rman
run
{
configure retention policy to recovery window of 8 days;
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';
allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc0_%d_%s_%p_%u_%T';
backup incremental level 0 tag='level 0' database skip inaccessible filesperset 10 plus archivelog filesperset 20;
release channel ch1;
}
allocate channel for maintenance device type disk;
crosscheck backup;
delete noprompt expired backup;
