Linux/Unix shell 脚本中调用SQL,RMAN脚本

Linux/Unix shell脚本中调用或执行SQL,RMAN 等为自动化作业以及多次反复执行提供了极大的便利，因此通过Linux/Unix shell来完成Oracle
的相关工作，也是DBA必不可少的技能之一。本文针对Linux/Unix shell脚本调用sql, rman 脚本给出了相关示例。

一、由shell脚本调用sql,rman脚本

[python] view plain copy

print?

1、shell脚本调用sql脚本

#首先编辑sql文件

oracle@SZDB:~> more dept.sql

connect scott/tiger

spool /tmp/dept.lst

set linesize 100 pagesize 80

select * from dept;

spool off;

exit;

#编辑shell脚本文件，在shell脚本内调用sql脚本

oracle@SZDB:~> more get_dept.sh

#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

sqlplus -S /nolog @/users/oracle/dept.sql #注意此处执行sql脚本的方法 -S 表示以静默方式执行

exit

#授予脚本执行权限

oracle@SZDB:~> chmod 775 get_dept.sh

-->执行shell脚本

oracle@SZDB:~> ./get_dept.sh

10 ACCOUNTING NEW YORK

20 RESEARCH DALLAS

30 SALES CHICAGO

40 OPERATIONS BOSTON

2、shell脚本调用rman脚本

#首先编辑RMAN脚本

oracle@SZDB:~> more rman.rcv

RUN {

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

CONFIGURE BACKUP OPTIMIZATION ON;

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/users/oracle/bak/%d_%F';

ALLOCATE CHANNEL CH1 TYPE DISK MAXPIECESIZE=4G;

ALLOCATE CHANNEL CH2 TYPE DISK MAXPIECESIZE=4G;

SET LIMIT CHANNEL CH1 READRATE=10240;

SET LIMIT CHANNEL CH1 KBYTES=4096000;

SET LIMIT CHANNEL CH2 READRATE=10240;

SET LIMIT CHANNEL CH2 KBYTES=4096000;

CROSSCHECK ARCHIVELOG ALL;

DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;

BACKUP

DATABASE FORMAT '/users/oracle/bak/%d_FULL__%U';

SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';

BACKUP ARCHIVELOG ALL FORMAT '/users/oracle/bak/%d_LF_%U' DELETE INPUT;

DELETE NOPROMPT OBSOLETE;

RELEASE CHANNEL CH1;

RELEASE CHANNEL CH2;

}

#编辑shell脚本文件，在shell脚本内调用rman脚本

oracle@SZDB:~> more rman_bak.sh

#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

$ORACLE_HOME/bin/rman target / cmdfile=/users/oracle/rman.rcv log=/users/oracle/bak/rman.log

exit

#授予脚本执行权限

oracle@SZDB:~> chmod 775 rman_bak.sh

#执行shell脚本

oracle@SZDB:~> ./rman_bak.sh

二、嵌入sql语句及rman到shell脚本

[python] view plain copy

print?

1、直接将sql语句嵌入到shell脚本

oracle@SZDB:~> more get_dept_2.sh

#!/bin/bash

# Author : Robinson Cheng

# Blog : http://blog.csdn.net/robinson_0612
# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

sqlplus -S /nolog <<EOF #EOF在此表示当输入过程中碰到EOF后，整个sql脚本输入完毕

connect scott/tiger

spool /tmp/dept.lst

set linesize 100 pagesize 80

select * from dept;

spool off;

exit; #退出sqlplus 环境

EOF

exit #推出shell脚本

#授予脚本执行权限

oracle@SZDB:~> chmod u+x get_dept_2.sh

#执行shell脚本

oracle@SZDB:~> ./get_dept_2.sh

DEPTNO DNAME LOC

---------- -------------- -------------

10 ACCOUNTING NEW YORK

20 RESEARCH DALLAS

30 SALES CHICAGO

40 OPERATIONS BOSTON

2、直接将sql语句嵌入到shell脚本(方式二，使用管道符号>代替spool来输出日志)

oracle@SZDB:~> more get_dept_3.sh

#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

sqlplus -S /nolog 1>/users/oracle/dept.log 2>&1 <<EOF

connect scott/tiger

set linesize 80 pagesize 80

select * from dept;

exit;

EOF

cat /users/oracle/dept.log

exit

#另一种实现方式，将所有的sql语句输出来生成sql脚本后再调用

oracle@SZDB:~> more get_dept_4.sh

#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

echo "conn scott/tiger

select * from dept;

exit;" >/users/oracle/get_dept.sql

sqlplus -silent /nolog @get_dept.sql 1>/users/oracle/get_dept.log 2>&1

cat get_dept.log

exit

3、将rman脚本嵌入到shell脚本

oracle@SZDB:~> more rman_bak_2.sh

#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

export ORACLE_SID=CNMMBO

$ORACLE_HOME/bin/rman log=/users/oracle/bak/rman.log <<EOF

connect target /

RUN {

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

CONFIGURE BACKUP OPTIMIZATION ON;

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/users/oracle/bak/%d_%F';

ALLOCATE CHANNEL CH1 TYPE DISK MAXPIECESIZE=4G;

ALLOCATE CHANNEL CH2 TYPE DISK MAXPIECESIZE=4G;

SET LIMIT CHANNEL CH1 READRATE=10240;

SET LIMIT CHANNEL CH1 KBYTES=4096000;

SET LIMIT CHANNEL CH2 READRATE=10240;

SET LIMIT CHANNEL CH2 KBYTES=4096000;

CROSSCHECK ARCHIVELOG ALL;

DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;

BACKUP

DATABASE FORMAT '/users/oracle/bak/%d_FULL__%U';

SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';

BACKUP ARCHIVELOG ALL FORMAT '/users/oracle/bak/%d_LF_%U' DELETE INPUT;

DELETE NOPROMPT OBSOLETE;

RELEASE CHANNEL CH1;

RELEASE CHANNEL CH2;

}

EXIT;

EOF

exit

#授予脚本执行权限

oracle@SZDB:~> chmod u+x rman_bak_2.sh

#执行shell脚本

oracle@SZDB:~> ./rman_bak_2.sh

RMAN> RMAN> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11> 12> 13> 14> 15> 16> 17> 18> 19> 20> 21> RMAN> oracle@SZDB:~>
