在ORACLE數(shù)據(jù)庫(kù)中，RMAN備份的腳本非常多，下面介紹一例shell腳本如何通過(guò)RMAN備份，以及FTP上傳RMAN備份文件以及歸檔日志文件的腳本。
fullback.sh 里面調(diào)用RMAN命令做數(shù)據(jù)庫(kù)備份，它使用的cmdfile為/home/oracle/backup/bin/fullback.rcv，同時(shí)在/home/oracle/backup/logs目錄下生成日志文件。
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文件非常簡(jiǎn)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(guò)FTP上傳到FTP服務(wù)器，一則數(shù)據(jù)庫(kù)服務(wù)器沒(méi)有這么多空間存儲(chǔ)多天的備份，二則是出于容災(zāi)、數(shù)據(jù)安全需要。
下面腳本中FTP服務(wù)器，用戶名密碼均使用xxx替代，在實(shí)際環(huán)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$date_today.log 21
68:
另外，關(guān)于歸檔日志也需要每隔2小時(shí)上傳一次到FTP服務(wù)器，2小時(shí)上傳一次歸檔日志的shell腳本如下所示：
1: [oracle@DB-Server bin]$ 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.$date_today.log 21
34:
最后需要將RMAN備份生成的日志文件，以及FTP上傳備份文件以及歸檔日志的記錄通過(guò)郵件形式發(fā)送給DBA或系統(tǒng)管理員，
1: [oracle@DB-Server bin]$ 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 $date_today"
6: content="Dear colleagues,
7:
8: Attached please find the logs of xxx(xxx.xxx.xxx.xxx) oracle database backup and transfer to FTP Server(xxx.xxx.xxx.xxx), please
9: review the file and check whether the backup succeeded or not,and double check all backups have been dumped to tape, many tha
10: nks
11:
12:
13:
14:
15: Best regards
16: Oracle Alert Services
17:
18: "
19: file="/home/oracle/backup/logs/fullbackup_$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 作業(yè)里面配置調(diào)用這些shell腳本。例如如下所示，在1：01分執(zhí)行fullback.sh ，每隔兩個(gè)小時(shí)（例如0:50、2:50...)執(zhí)行一次ftp2hours.sh, 在每天早上8:40執(zhí)行chkbackandmail.sh 發(fā)送fullback.sh 以及ftp2hour.sh的執(zhí)行日志記錄。
INSERT INTO BOOK(bookid,name,price)? VALUES('100123','oracle ',54);
或者
INSERT INTO tablename(bookid,name,price)
SELECT '100123','oracle,54 FROM DUAL；
總結(jié)下Oracle 中的Insert用法
1.標(biāo)準(zhǔn)Insert --單表單行插入
語(yǔ)法:
INSERT INTO table [(column1,column2,...)] VALUE (value1,value2,...)
例子:
insert into dep (dep_id,dep_name) values(1,'技術(shù)部');
2, 無(wú)條件 Insert all --多表多行插入
語(yǔ)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,有條件的Insert
語(yǔ)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, 旋轉(zhuǎn)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;
用job，具體用法：
declare
n_job binary_integer;
begin
dbms_job.submit(n_job, '你要執(zhí)行的東西', sysdate, TRUNC(LAST_DAY(SYSDATE))+4+2/24);
end;
-- 每月4號(hào)執(zhí)行
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(LAST_DAY(SYSDATE))+4+2/24');
-- 每分鐘執(zhí)行一次
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(sysdate,’mi’) + 1 / (24*60)');
-- 凌晨?jī)牲c(diǎn)執(zhí)行
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(sysdate) + 1 + 2/24');
-- 每周一凌晨2點(diǎn)執(zhí)行 周一是每周的第二天next_day(sysdate,2)同理周二是第三天,next_day(sysdate,3)
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(next_day(sysdate,2))+2/24');
-- 每月1日凌晨?jī)牲c(diǎn)執(zhí)行
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(LAST_DAY(SYSDATE))+1+2/24');
-- 每季第一天凌晨?jī)牲c(diǎn)執(zhí)行
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'TRUNC(ADD_MONTHS(SYSDATE,3),'Q') + 2/24');
-- 每年7月1日和1月1日凌晨2點(diǎn)
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate,'ADD_MONTHS(trunc(sysdate,'yyyy'),6)+2/24');
-- 每年1月1日凌晨2點(diǎn)執(zhí)行
dbms_job.submit(n_job_01,'你調(diào)的東西',sysdate, 'Add_months(trunc(sysdate,'yyyy'), 12) +2/24');
