linux服务器下oracle开机自启动设置

1、首先切换到Oracle用户

[oracle@oracletest ~]$ cd /u01/app/oracle/product/11.2.0/db_1/bin/       -----标红字体部分数据库可能不一样，有的是dbhome_1，以自己实际配置目录为准

[oracle@oracletest bin]$ vi dbstart 

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     ############此处原来是$1，改成$ORACLE_HOME
if [ ! $ORACLE_HOME_LISTNER ] ; then
  echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
  echo "Usage: $0 ORACLE_HOME"
else
  LOG=$ORACLE_HOME_LISTNER/listener.log

2、用root用户编辑oratab和rc.local

[root@oracletest ~]# 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.
#
#
oadb:/u01/app/oracle/product/11.2.0/db_1:Y  ###此处原来是N，改为Y

 

[root@oracletest ~]# 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行，其中标红字体部分数据库可能不一样，有的是dbhome_1，以自己实际配置目录为准
su oracle -lc "/u01/app/oracle/product/11.2.0/db_1/bin/lsnrctl start"    
su oracle -lc  /u01/app/oracle/product/11.2.0/db_1/bin/dbstart  

经过上面两步操作，数据库服务器重启后，数据库也会自动启动。

以上均为实际操作示例，最终参考如下链接，致谢
