阮胜昌的技术记录站-LinuxMySQL数据库运维

    大部分真实生产环境中的服务器都是linux，oracle DBA工作过程中有时会遇到通过shell脚本批量执行sql脚本完成某一项任务,最典型的例子是oracle DBCA创建的数据库脚本就是这种模式，适宜环境下稍加修改便可完全通过脚本完成新库的安装，小编在这里将简单两种应用样例列举如下，方便以后工作.

---------------------------------------shell文件和sql文件组合样例---------------------------------------------
---------linux中的执行shell文件中包含了sql内容：
[oracle@CentOS5 ~]$ cat spool.sh
#!/bin/sh
OLD_UMASK=`umask`
umask 0027
umask ${OLD_UMASK}
ORACLE_SID=taxi; export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH; export PATH
/oracle/product/10.2.0/db_1/bin/sqlplus / as sysdba < set linesize 120
set pagesize 100
spool  /home/oracle/spool.txt
select * from scott.dept;
spool off
exit;
EOF
[oracle@CentOS5 ~]$
------->>执行情况:
[oracle@CentOS5 ~]$ sh spool.sh

---------------------------------------shell文件和sql文件分开样例---------------------------------------------
---------linux中的执行shell文件内容：

[oracle@CentOS5 ~]$ cat test.sh
#!/bin/sh
OLD_UMASK=`umask`
umask 0027
umask ${OLD_UMASK}
ORACLE_SID=taxi; export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH; export PATH
/oracle/product/10.2.0/db_1/bin/sqlplus / as sysdba @/home/oracle/test.sql
[oracle@CentOS5 ~]$

---------sql文件中内容:
[oracle@CentOS5 ~]$ cat test.sql
set linesize 120
set pagesize 120
spool /home/oracle/test.txt
select * from scott.emp;
spool off;
exit;

--------->>执行情况:
