oracle开机自启（oracle11g2r+centos6.5）

1.用oracle用户编辑dbstart文件

登入oracle用户，切换到$ORACLE_HOME/bin目录下，修改文件dbstart。

[oracle@ST ~]$ vi /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart 

修改：看下面注释部分进行修改。

LOGMSG="logger -puser.alert -s "  
  
trap 'exit' 1 2 3  
  
# for script tracing  
case $ORACLE_TRACE in  
  T) set -x ;;  
esac  
  
# Set path if path not set (if called from /etc/rc)  
SAVE_PATH=/bin:/usr/bin:/etc:${PATH} ; export PATH  
SAVE_LLP=$LD_LIBRARY_PATH  
  
# First argument is used to bring up Oracle Net Listener  
ORACLE_HOME_LISTNER=$ORACLE_HOME    --这里原本是$1，这里改成$ORACLE_HOME即可。  
if [ ! $ORACLE_HOME_LISTNER ] ; then  
  echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"  
  echo "Usage: $0 ORACLE_HOME"  
else

2.用root用户编辑文件oratab和rc.local

参照下面的注释部分进行修改。

[root@ST ~]# vi /etc/oratab   
  
# This file is used by ORACLE utilities.  It is created by root.sh  
# and updated by either Database Configuration Assistant while creating  
# a database or ASM Configuration Assistant while creating ASM instance.  
  
# 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:/u01/app/oracle/product/11.2.0/dbhome_1:Y   --这里原本是N，改成Y即可。  

[root@ST ~]# vi /etc/rc.d/rc.local   
  
#!/bin/sh  
#  
# This script will be executed *after* all the other init scripts.  
# You can put your own initialization stuff in here if you don't  
# want to do the full Sys V style init stuff.  
  
touch /var/lock/subsys/local  
  
--在空白处添加下面两句话。  
su oracle -lc "/u01/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"    
su oracle -lc  /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart  

所有这些步骤做完了，就配置好了Oracle在Linux下的自启动了
