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

1、shell脚本调用sql脚本#首先编辑sql文件oracle@SZDB:~> more dept.sqlconnect scott/tigerspool /tmp/dept.lstset linesize 100 pagesize 80select * 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 variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBOsqlplus -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     DEPTNO DNAME          LOC---------- -------------- -------------        10 ACCOUNTING     NEW YORK        20 RESEARCH       DALLAS        30 SALES          CHICAGO        40 OPERATIONS     BOSTON2、shell脚本调用rman脚本#首先编辑RMAN脚本oracle@SZDB:~> more rman.rcvRUN {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 variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBO$ORACLE_HOME/bin/rman target / cmdfile=/users/oracle/rman.rcv log=/users/oracle/bak/rman.logexit#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

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 variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBOsqlplus -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/tigerspool /tmp/dept.lstset linesize 100 pagesize 80select * from dept;spool off;exit;                       #退出sqlplus 环境EOFexit                        #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     BOSTON2、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 variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBOsqlplus -S /nolog 1>/users/oracle/dept.log 2>&1 <<EOFconnect scott/tigerset linesize 80 pagesize 80select * from dept;exit;EOFcat /users/oracle/dept.logexit#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 variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBOecho "conn scott/tiger select * from dept;exit;" >/users/oracle/get_dept.sqlsqlplus -silent /nolog  @get_dept.sql 1>/users/oracle/get_dept.log 2>&1cat get_dept.logexit3、将rman脚本嵌入到shell脚本oracle@SZDB:~> more rman_bak_2.sh#!/bin/bash# set environment variableif [ -f ~/.bashrc ]; then        . ~/.bashrcfiexport ORACLE_SID=CNMMBO$ORACLE_HOME/bin/rman log=/users/oracle/bak/rman.log <<EOFconnect 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;EOFexit        #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.shRMAN> RMAN> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11> 12> 13> 14> 15> 16> 17> 18> 19> 20> 21> RMAN> oracle@SZDB:~>
