这篇文章主要介绍了centos 6.5 oracle开机自启动的环境配置详解的相关资料,需要的朋友可以参考下

centos 6.5 oracle开机自启动的环境配置详解

环境:centos 6.5 + oracle 11g

自启动之前问题

虚拟机里的oracle环境,每次重启完系统,用plsql developer连接,先是报错:

无tns监听程序

解决方法是切换到系统的oracle用户,执行lsnrctl start,但是执行之前,因为oracle_home环境变量没有生效,还要是环境变量文件生效,步骤如下:

[oracle@localhost ~]$ source .bash_profile
 
[oracle@localhost ~]$ echo $oracle_home
/home/oracle/app/oracle/product/11.2.0/dbhome_1
 
[oracle@localhost ~]$ lsnrctl start

启动完成后,再次连接,又报错:

oracle没有启动。启动步骤如下:

配置自启动

下面把上述过程都配置成开机启动。

环境变量生效

可能是因为我的oracle用户不是桌面登录的,是从终端su切换过来的,.bash_profile文件没有运行。我把文件里的内容写入.bashrc文件后,重启就可以了。

tns监听以及oracle服务自启动

编辑: /etc/oratab文件,把最后一行的n改成y

# this file is used by oracle utilities. it is created by root.sh
# and updated by the database configuration assistant when creating
# a database.
 
# 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:/home/oracle/app/product/11.2.0/dbhome_1:y

路径可能不同

编辑 /etc/rc.local 文件,增加 最后两行:

#!/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
service smb restart
su - oracle -c 'lsnrctl start'
su - oracle -c 'dbstart'
su - oracle -c 'emctl start dbconsole'

dbstart是数据库自带的启动脚本,我们只要加到rc.local中让它开机调用就可以了。但是还需要编辑一下它。修改dbstart的oracle_home_listner,使其指向$oracle_home:

?

2
# first argument is used to bring up oraclenet listener
oracle_home_listner=$oracle_home

重启虚拟机,发现plsql developer可以直接连接上了。
