oracle的環境配置-設置開機（Linux）自動啟動Oracle關機自動關閉Oracle

設置開機（Linux）自動啟動Oracle關機自動關閉Oracle

1、切換到root用戶下，確認啟動文件和關閉文件是存在
[oracle@oracle3 bin]$ pwd
/u01/oracle/product/10.2.0/db_1/bin
[oracle@oracle3 bin]$ ls dbstart
dbstart                              --sqlplus執行startup的時候調用的腳本
[oracle@oracle3 bin]$ ls dbshut
dbshut                               --sqlplus執行shutdown的時候調用的腳本


2、修改oratab文件

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

ORCL:/u01/oracle/product/10.2.0/db_1:Y  --將N改為Y

3、測試啟動文件和關閉文件的正確性

/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.  --數據庫是關閉的
注意： conn /as sysdba = conn sys/orcl as sysdba

SQL> conn sys/orcl as sysdba
Connected to an idle instance.  --連接到一個空閑的例程表示數據庫沒有啟動

SQL> conn sys/orcl@ORCL as sysdba

不管進行什么操作，都必須連接一下，用sysdba的身份登錄校驗操作系統的密碼文件。

[oracle@oracle3 bin]$ dbstart   --測試啟動文件是可用的
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr

SQL> conn /as sysdba
Connected.   --

4、編寫一段shell腳本

[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、修改權限

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

6、將文件鏈接到啟動區域和關閉區域

[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、測試：

init 6
