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.##orcl:/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 functionsif [ -f ~/.bashrc ]; then        . ~/.bashrcfi# User specific environment and startup programsPATH=$PATH:$HOME/binexport PATH# add at the last lineumask 022export ORACLE_BASE=/usr/oracle/appexport ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1export PATH=$PATH:$ORACLE_HOME/bin#在文件末尾增加

export ORACLE_SID=orcl

[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/functionsLOCKFILE=/var/lock/subsys/oracleORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1ORACLE_USER=oraclecase "$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 1esacexit 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

相应关闭oracle数据库的命令为

[root@localhost ~]# service oracle stop

[6] 设置oracle为开机自启动

[root@localhost ~]# chkconfig oracle on[root@localhost ~]# chkconfig --list oracleoracle          0:off   1:off   2:on    3:on    4:on    5:on    6:off
