oracle rman备份脚本怎么写
在ORACLE数据库中，RMAN备份的脚本非常多，下面介绍一例shell脚本如何通过RMAN备份，以及FTP上传RMAN备份文件以及归档日志文件的脚本。
fullback.sh 里面调用RMAN命令做数据库备份，它使用的cmdfile为/home/oracle/backup/bin/fullback.rcv，同时在/home/oracle/backup/logs目录下生成日志文件。
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=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
10:
11: TMP=/tmp; export TMP
12:
13: TMPDIR=$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文件非常简单， 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生成的备份文件，需要通过FTP上传到FTP服务器，一则数据库服务器没有这么多空间存储多天的备份，二则是出于容灾、数据安全需要。
下面脚本中FTP服务器，用户名密码均使用xxx替代，在实际环境中，使用具体的信息替代即可。
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$date_today.log 21
68:
另外，关于归档日志也需要每隔2小时上传一次到FTP服务器，2小时上传一次归档日志的shell脚本如下所示：
1: [oracle@DB-Server bin]$ 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.$date_today.log 21
34:
最后需要将RMAN备份生成的日志文件，以及FTP上传备份文件以及归档日志的记录通过邮件形式发送给DBA或系统管理员，
1: [oracle@DB-Server bin]$ 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 $date_today"
6: content="Dear colleagues,
7:
8: Attached please find the logs of xxx(xxx.xxx.xxx.xxx) oracle database backup and transfer to FTP Server(xxx.xxx.xxx.xxx), please
9: review the file and check whether the backup succeeded or not,and double check all backups have been dumped to tape, many tha
10: nks
11:
12:
13:
14:
15: Best regards
16: Oracle Alert Services
17:
18: "
19: file="/home/oracle/backup/logs/fullbackup_$date_today.log,/home/oracle/backup/logs/ftp$date_today.log"
20: echo "#!/usr/bin/perl" /home/oracle/backup/bin/sendmail.pl
21: echo "use Mail::Sender;" /home/oracle/backup/bin/sendmail.pl
22: echo "\$sender = new Mail::Sender {smtp = 'xxx.xxx.xxx.xxx', from = 'xxxx@xxx.com'}; " /home/oracle/backup/bin/sendmai
23: l.pl
24: echo "\$sender-MailFile({to = 'xxx@esquel.com'," /home/oracle/backup/bin/sendmail.pl
25: echo "cc='xxx@xxx.com,xxx@xxx.com,xxx@xxx.com'," /home/oracle/backup/b
26: in/sendmail.pl
27: echo "subject = '$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
最后在Crontab 作业里面配置调用这些shell脚本。例如如下所示，在1：01分执行fullback.sh ，每隔两个小时（例如0:50、2:50...)执行一次ftp2hours.sh, 在每天早上8:40执行chkbackandmail.sh 发送fullback.sh 以及ftp2hour.sh的执行日志记录。
oracle数据库这样的（照片所示）rman备份脚本怎么写
只考虑备份，不考虑其他情况下：
root下的3个rman备份级别的脚本：
#cat
rman_0.sql
backup
incremental
level
database;
#cat
rman_1.sql
backup
incremental
level
1
database;
#cat
rman_1c.sql
backup
incremental
level
1
cumulative
database;
root下的调用rman脚本
#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的计划任务：
#crontab
-e
1
*
*
/root/rman_0.sh
2
*
*
1
/root/rman_1.sh
2
*
*
2
/root/rman_1.sh
3
*
*
3
/root/rman_1c.sh
2
*
*
4
/root/rman_1.sh
3
*
*
5
/root/rman_1c.sh
2
*
*
6
/root/rman_1.sh
11g里只有0和1两个备份级别，请自行对应oracle低版本
level
0是full
level
1是差异增量备份
--和前一次备份比较，将这个期间改变的数据备份下来
level
1c是累计增量备份
--和比他小得级别相比（即全备份），改变的数据备份
然后根据实际情况还要将备份的策略往脚本添加
