CentOS Oracle11gR2 设置开机自启动

[1] 更改/etc/oratab

[root@localhost ~]# vi /etc/oratab

#

# 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.

#

#

MFGS:/usr/oracle/app/product/11.2.0/dbhome_1:Y #改变此处

[2] oracle用户profile文件中增加SID环境变量

[root@localhost ~]# vi /usr/oracle/.bash_profile

# .bash_profile



# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi



# User specific environment and startup programs



PATH=$PATH:$HOME/bin



export PATH



# add at the last line



umask 022

export ORACLE_BASE=/usr/oracle/app



export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export PATH=$PATH:$ORACLE_HOME/bin

#在文件末尾增加

export ORACLE_SID=MFGS

[3] 创建启动Oracle的Init脚本

[root@localhost ~]# vi /etc/rc.d/init.d/oracle

# this is an example #!/bin/bash # oracle: Start/Stop Oracle Database 11g R2 # # chkconfig: 345 90 10

# description: The Oracle Database is an Object-Relational Database Management System. # # processname: oracle . /etc/rc.d/init.d/functions LOCKFILE=/var/lock/subsys/oracle ORACLE_HOME=/usr/oracle/app/product/11.2.0/dbhome_1 ORACLE_USER=oracle case "$1" in

'start') if [ -f $LOCKFILE ]; then

      echo $0 already running. exit 1

   fi

   echo -n $"Starting Oracle Database:"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl start"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl start dbconsole"

   touch $LOCKFILE ;; 'stop') if [ ! -f $LOCKFILE ]; then

      echo $0 already stopping. exit 1

   fi

   echo -n $"Stopping Oracle Database:"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl stop"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbshut"

   su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl stop dbconsole"

   rm -f $LOCKFILE ;; 'restart') $0 stop $0 start ;; 'status') if [ -f $LOCKFILE ]; then

      echo $0 started. else

      echo $0 stopped. fi

 ;; *) echo "Usage: $0 [start|stop|status]"

 exit 1

esac



exit 0

[4] 更改启动脚本权限

[root@localhost ~]# chmod 755 /etc/rc.d/init.d/oracle

[5] 启动oracle数据库

[root@localhost ~]# service oracle start
