Linux下Oracle开机自启动

原文地址：http://blog.csdn.net/cscscscsc/article/details/51044541

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::
 #
 # 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。
