在CentOS 6.3下安裝完Oracle 10g R2，重開機(jī)之后，你會(huì)發(fā)現(xiàn)Oracle沒有自行啟動(dòng)，這是正常的，因?yàn)樵贚inux下安裝Oracle的確不會(huì)自行啟動(dòng)，必須要自行設(shè)定相關(guān)參數(shù)，首先先介紹一般而言如何啟動(dòng)oracle。

一、在Linux下啟動(dòng)Oracle

登錄到CentOS，切換到oracle用戶權(quán)限

# su – oracle

接著輸入：

$ sqlplus "/as sysdba"

原本的畫面會(huì)變?yōu)?BR>SQL>

接著請(qǐng)輸入
SQL> startup

就可以正常的啟動(dòng)數(shù)據(jù)庫(kù)了。

另外停止數(shù)據(jù)庫(kù)的指令如下：
SQL> shutdown immediate

二、檢查Oracle DB監(jiān)聽器是否正常

回到終端機(jī)模式，輸入：

$ lsnrctl status

檢查看看監(jiān)聽器是否有啟動(dòng)

如果沒有啟動(dòng)，可以輸入：

$ lsnrctl start

啟動(dòng)監(jiān)聽器

SQL> conn sys@orcl as sysdba

然后輸入密碼，sys以sysdba身份登入數(shù)據(jù)庫(kù)。

三、啟動(dòng)emctl

另外也可以發(fā)現(xiàn)http://localhost.localdomain:1158/em 目前是沒有反應(yīng)的，這邊要另外啟動(dòng)，啟動(dòng)的指令如下：

$ emctl start dbconsole

這個(gè)指令運(yùn)行時(shí)間較長(zhǎng)，執(zhí)行完的畫面如下：

手動(dòng)啟動(dòng)Oracle數(shù)據(jù)庫(kù)完畢，下面創(chuàng)建系統(tǒng)自行啟動(dòng)Oracle的腳本。

四、Oracle啟動(dòng)停止腳本

1. 修改Oracle系統(tǒng)配置文件：/etc/oratab，只有這樣，Oracle 自帶的dbstart和dbshut才能夠發(fā)揮作用。

# vi /etc/oratab
orcl:/opt/oracle/102:Y

# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME:N|Y>:

2. 在 /etc/init.d/ 下創(chuàng)建文件oracle，內(nèi)容如下：

復(fù)制代碼 代碼如下:

#!/bin/sh
# chkconfig: 35 80 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
ORA_HOME=/opt/oracle/102
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracle
echo "Done"
# Start the Listener:
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle
echo "Done."
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
touch /var/lock/subsys/oracle

'stop')
# Stop the Oracle Listener:
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle
echo "Done."
rm -f /var/lock/subsys/oracle
# Stop the Oracle Database:
echo "Stoping Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracle
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle

'restart')
$0 stop
$0 start

esac

3. 改變文件權(quán)限
# chmod 755 /etc/init.d/oracle

4. 添加服務(wù)
# chkconfig --level 35 oracle on

5. 需要在關(guān)機(jī)或重啟機(jī)器之前停止數(shù)據(jù)庫(kù)，做一下操作
# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle   //關(guān)機(jī)
# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle   //重啟 

6. 使用方法
# service oracle start        //啟動(dòng)oracle
# service oracle stop        //關(guān)閉oracle
# service oracle restart     //重啟oracle

7. 測(cè)試

a. 開機(jī)自啟動(dòng)
