linux 下开启oracle服务和开启监听和 开机自动重启

1. 手动重启

su - oracle  切换到oracle用户模式下

sqlplus /nolog  //登录sqlplus

SQL> connect /as sysdba  //连接oracle

SQL> startup //起动数据库

SQL> exit  //退出sqlplus ，起动监听

 

cd $ORACLE_HOME/bin //进入oracle安装目录

lsnrctl start  //起动监听

2 . 自动重启

[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

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
 
--su oracle 指用户名
