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
