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
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;
