解决Oracle使用DBSTART启动的问题

在linux系统下安装完成oracle以后需要设置oracle开机启动,以防以后使用中突然断电,需要手动启动oracle
我在设置开机启动oracle的时候使用的dbstarte
因为使用dbstart的时候需要用到linux下的/etc/oratab 文件如果没有此文件的话可以从

# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.

# A colon, ':', is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively.  The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
xxxx:/opt/app/oracle/product/10.2:Y

这里复制粘贴.
其中第一个冒号前面的是oracle的SID 设置为自己需要的SID
后面为ORACLE_HOME就是oracle在本机的安装路径这个路径必须和设置在/etc/profile的ORACLE_HOME相同
最后一个是是否使用dbstart启动
这个文件复制好以后
可以使用如下代码创建oratab

 cd /etc/
 vi oratab
 复制上面的内容粘贴进去
然后输入:wq

保存成功以后这个步骤就算完成了

 首先打开/etc/profile
 vi /etc/profile
 在文件的最后面添加如下代码
export ORACLE_HOME="oracle的安装路径"
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH

建立oracle的全局变量
然后在/etc/init.d 下面建立oracle的启动文件

cd /etc/init.d
vi oracle
复制下面的代码
#!/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/app/oracle/product/10.2
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.log
date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log
su - $ORA_OWNER -lc "$ORA_HOME/bin/dbstart" >> /var/log/oracle.log
echo "Done"

# Start the Listener:
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle.log
date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log
su - $ORA_OWNER -lc "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle.log
echo "Done."
echo "-------------------------------------------------" >> /var/log/oracle.log
date +" %T %a %D : Finished." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log

;;

'stop')
# Stop the Oracle Listener:
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle.log
date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log
su - $ORA_OWNER -lc "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle.log
echo "Done."

# Stop the Oracle Database:
echo "Stoping Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle.log
date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log
su - $ORA_OWNER -lc "$ORA_HOME/bin/dbshut" >>/var/log/oracle.log
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle.log
date +" %T %a %D : Finished." >> /var/log/oracle.log
echo "-------------------------------------------------" >> /var/log/oracle.log
;;

'restart')
$0 stop
$0 start
;;
esac
:wq

文件路径按照自己的需要需要修改一下
保存上面文件后
需要输入下面的命令

chmod -x oracle
chkconfig --add oracle
chkconfig --level 3 5 oracle on
上面命令是赋予oracle执行权限
把oracle添加在系统启动列表中
输入 
chkconfig --list|grep oracle
可以查看是否添加成功

完成上面配置 基本就完成了oracle在centenos下面的开机启动了
