设置开机（Linux）自动启动Oracle关机自动关闭Oracle

1、切换到root用户下，确认启动文件和关闭文件是存在
[oracle@oracle3 bin]$ pwd
/u01/oracle/product/10.2.0/db_1/bin
[oracle@oracle3 bin]$ ls dbstart
dbstart                              --sqlplus执行startup的时候调用的脚本
[oracle@oracle3 bin]$ ls dbshut
dbshut                               --sqlplus执行shutdown的时候调用的脚本


2、修改oratab文件

[oracle@oracle3 etc]$ vim /etc/oratab

ORCL:/u01/oracle/product/10.2.0/db_1:Y  --将N改为Y

3、测试启动文件和关闭文件的正确性

/u01/oracle/product/10.2.0/db_1/bin

[oracle@oracle3 bin]$ export ORACLE_SID=ORCL

[oracle@oracle3 bin]$ dbshut

[oracle@oracle3 bin]$ sqlplus /nolog

SQL> conn /as sysdba
Connected to an idle instance.  --数据库是关闭的
注意： conn /as sysdba = conn sys/orcl as sysdba

SQL> conn sys/orcl as sysdba
Connected to an idle instance.  --连接到一个空闲的例程表示数据库没有启动

SQL> conn sys/orcl@ORCL as sysdba

Warning: You are no longer connected to ORACLE.  --因为数据库关闭了，是无法用监听器访问的，仅仅可以以sysdba的身份连接而已。

不管进行什么操作，都必须连接一下，用sysdba的身份登录校验操作系统的密码文件。

[oracle@oracle3 bin]$ dbstart   --测试启动文件是可用的
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr

[oracle@oracle3 bin]$ sqlplus /nolog

SQL> conn /as sysdba
Connected.   --

4、编写一段shell脚本

[root@oracle3 ~]# cd /etc/rc.d/init.d
[root@oracle3 init.d]# touch start_shut
[root@oracle3 init.d]# vi start_shut
----------------------------------------------
#!/bin/sh
  OPT_=$1
  case "$OPT_" in
  start)
       /bin/echo "$0  :  (start)"
       #
       # your service startup command goes here
       #
       su - oracle -c "/u01/oracle/product/10.2.0/db_1/bin/lsnrctl start"
       su - oracle -c "/u01/oracle/product/10.2.0/db_1/bin/dbstart"
       # NOTE:Must exit with zero unless error is server
       chmod 1777 /tmp
       chown sys:sys /tmp
       exit 0
       ;;
   stop)
      /bin/echo "$  :  (stop)"
      #
      # your service shutdown command goes here.
      #
      su - oralce -c "/u01/oracle/product/10.2.0/db_1/bin/dbshut"
      su - oracle -c "/u01/oracle/product/10.2.0/db_1/bin/lsnrctl stop"
      #Note: Must exit with zero unless error is server
      exit 0
      ;;
*) /bin/echo ''
   /bin/echo "Usage: $0[start|stop]"
   /bin/echo "Invalid argument ==>\"${OPT_}\""
   /bin/echo ''
   exit 0
   ;;
esac
----------------------------------------------------------------------------------

5、修改权限

[root@oracle3 init.d]# chmod 755 start_shut

6、将文件链接到启动区域和关闭区域

[root@oracle3 init.d]# cd /etc/rc5.d
[root@oracle3 rc5.d]# ln -s /etc/rc.d/init.d/start_shut S99start_shut
[root@oracle3 rc5.d]# cd /etc/rc0.d
[root@oracle3 rc0.d]# ln -s /etc/rc.d/init.d/start_shut K01start_shut

7、测试：

init 6
