oracle加入开机启动

1.编辑: vi /etc/oratab，把最后一行的N改为Y

# 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:N  
orcl:/u01/app/oracle:Y    #这里把"N"改为"Y" 

2.修改 /etc/rc.local，在最后添加两句

#!/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  
  
# 添加下面两条  
su - oracle -c 'dbstart'  
su - oracle -c 'lsnrctl start'
