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

3: #!/bin/bash

5: export ORACLE_BASE=/u01/app/oracle

7: export ORACLE_SID=gps

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

3: run{

5: allocate channel c4 type disk;

7: backup as compressed backupset

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

3: #!/bin/sh、

5: rm -f /home/oracle/.netrc

7: date_yesterday=`date -d'yesterday' +%Y_%m_%d`

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

3: #!/bin/sh

5: rm -f /home/oracle/.netrc

7: date_yesterday=`date -d'yesterday' +%Y_%m_%d`

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,

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

database;

#cat

rman_1c.sql

backup

incremental

level

cumulative

database;

root下的调用rman脚本

#cat

rman_0.sh

#!/bin/bash

oracle

-c

"rman

target

sys/SHUIMITAO@rabbit

@/root/rman_0.sql"

#cat

rman_1.sh

#!/bin/bash

oracle

-c

"rman

target

sys/SHUIMITAO@rabbit

@/root/rman_1.sql"

#cat

rman_1c.sh

#!/bin/bash

oracle

-c

"rman

target

sys/SHUIMITAO@rabbit

@/root/rman_1c.sql"

root的计划任务：

#crontab

-e

/root/rman_0.sh

/root/rman_1.sh

/root/rman_1c.sh

/root/rman_1.sh

/root/rman_1c.sh

/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

Oracle数据库备份脚本怎么写？

没必要用root权限执行，oracle用户同样可以执行crontab计划任务

1、su - oracle

crontab -e

0 4 * * 0 /home/oracle/exp.sh 21 /home/oracle/script_exp.log;

0～59 表示分

0～23 表示小时

1～31 表示日

1～12 表示月份

0～6 表示星期（其中0表示星期日）

2、cat /home/oracle/exp.sh

. ~/.bash_profile

bakdir=/opt/dbbak

logdir=/home/oracle/dbbak

rq=$(date +%Y%m%d)

exp system/***** owner=jysh file=${bakdir}/jysh_${rq}.dmp log=${logdir}/jysh_${rq}.log;

find ${bakdir} -type f -mtime +30 -exec rm -rf {} \;

oracle数据库，批量插入数据脚本

批量插入数据脚本

1、第一种批量插入数据脚本，可以基本满足要求。理解上较为简单，所以这个最常用。

NEXTVAL和CURRVAL的区别：

1、如果 sequence.CURRVAL 和 sequence.NEXTVAL 都出现在一个 SQL 语句中，则序列只增加一次。在这种情况下，每个 sequence.CURRVAL 和 sequence.NEXTVAL 表达式都返回相同的值，不管在语句中sequence.CURRVAL 和 sequence.NEXTVAL 的顺序。

执行脚本结果如下：

3、两个表，同时批量插入数据的脚本

3、

4、涉及子表时，批量插入数据脚本,

5、批量修改数据：

时间取数方式：

一、SYSTIMESTAMP（取当前系统值）

二、SYSDATE（取当前系统值，但只精确到时，分和秒都为0）

三、固定值为：TO_TIMESTAMP ('2019-2-12 15:24:45.703000', 'yyyy-mm-dd hh24:mi:ss.ff6')

把固定的字段改为变量：

方式一：’||i||’ 例：’{“no”:“111’||i||’”}’（此方式）

方式二：concat 例：concat(concat(’{“blNo”:111"’,i),’"}’)

linux下备份oracle的脚本怎么写

把下面的代码保存为服务器端的脚本，执行即可。PS：需要自己替换一下双引号中的内容

#!/bin/sh

. $HOME/.bash_profile

export ORACLE_SID="你的数据库的SID"

CutDATE=`date '+%Y-%m%d-%H%M'`

DATE=`date -d '-2 day' '+%Y-%m%d'`

export NLS_LANG="你的字符集设定"

exp "具有权限的账号"/"密码" file=/home/oracle/2014/"你的数据库的SID"_$CutDATE.dmp log=/home/oracle/2014/"你的数据库的SID"_$CutDATE.log owner=user1,user2

oracle insert into 脚本怎么写

INSERT INTO BOOK(bookid,name,price) VALUES('100123','oracle ',54);

或者

INSERT INTO tablename(bookid,name,price)

SELECT '100123','oracle,54 FROM DUAL；

总结下Oracle 中的Insert用法

1.标准Insert --单表单行插入

语法:

INSERT INTO table [(column1,column2,...)] VALUE (value1,value2,...)

例子:

insert into dep (dep_id,dep_name) values(1,'技术部');

2, 无条件 Insert all --多表多行插入

语法:

INSERT [ALL] [condition_insert_clause]

[insert_into_clause values_clause] (subquery)

示例:

INSERT ALL

INTO sal_history(emp_id,hire_date,salary) values (empid,hiredate,sal)

INTO mgr_history(emp_id,manager_id,salary) values (empid,hiredate,sal)

SELECT employee_id empid,hire_date hiredate,salary sal,manager_id mgr

FROM employees

WHERE employee_id200;

3,有条件的Insert

语法:

INSERT [ALL | FIRST]

WHEN condition THEN insert_into_clause values_clause

[WHEN condition THEN] [insert_into_clause values_clause]

......

[ELSE] [insert_into_clause values_clause]

Subquery；

示例:

Insert All

when id5 then into z_test1(id, name) values(id,name)

when id2 then into z_test2(id) values(id)

else into z_test3 values(name)

select id,name from z_test;

4, 旋转Insert (pivoting insert)

create table sales_source_data (

employee_id number(6),

week_id number(2),

sales_mon number(8,2),

sales_tue number(8,2),

sales_wed number(8,2),

sales_thur number(8,2),

sales_fri number(8,2)

);

insert into sales_source_data values (176,6,2000,3000,4000,5000,6000);

create table sales_info (

employee_id number(6),

week number(2),

sales number(8,2)

);

示例如下:

insert all

into sales_info values(employee_id,week_id,sales_mon)

into sales_info values(employee_id,week_id,sales_tue)

into sales_info values(employee_id,week_id,sales_wed)

into sales_info values(employee_id,week_id,sales_thur)

into sales_info values(employee_id,week_id,sales_fri)

select employee_id,week_id,sales_mon,sales_tue,

sales_wed,sales_thur,sales_fri

from sales_source_data;
