B. 如何在Linux中设置开机自动启动oracle
对于LINUX 操作系统 有很多技术知识是我们需要学习的。这里我就给大家介绍Linux中设置oracle开机自动启动的 方法 。一起来看看吧。
Linux中设置oracle开机自动启动的方法
在terminal中切换到root用户
查看/etc/oratab文件的内容，其内容如下
[root@golonglee ~]# cat /etc/oratab | grep -v ^$
#
# 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::
#
# 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.
#
#
oel63:/home/oracle/app/oracle/proct/11.2.0/dbhome_1:N
使用命令vi /etc/oratab编辑文件/etc/oratab，在最后添加如下内容
##### what I have written is as following
oel63:/home/oracle/app/oracle/proct/11.2.0/dbhome_1:Y
#####Finished wrote in 2015-12-24
说明：/home/oracle/app/oracle/proct/11.2.0/dbhome_1为oracle的安装目录，要根据实际情况进行修改。
(注意：图中我用红色标记的N要改成Y)
找到最后的内容
oel63:/home/oracle/app/oracle/proct/11.2.0/dbhome_1:N
复制该行oel63:/home/oracle/app/oracle/proct/11.2.0/dbhome_1:N并注释掉
粘贴该行，并将该行
oel63:/home/oracle/app/oracle/proct/11.2.0/dbhome_1:N最后的N
改为Y
最后按2次ESC键，并输入:wq并按下enter保存，退出
使用命令vi /etc/rc.d/rc.local编辑rc.local文件，添加如下内容
##### what I have written is as following
su oracle -lc "/home/oracle/app/oracle/proct/11.2.0/dbhome_1/bin/lsnrctl start"
su oracle -lc /home/oracle/app/oracle/proct/11.2.0/dbhome_1/bin/dbstart
#####Finished wrote in 2015-12-24
说明：因为第一行命令中有空格所以用双引号(英文的双引号)
/home/oracle/app/oracle/proct/11.2.0/dbhome_1为oracle的安装目录，要根据实际情况进行修改。
最后按2次ESC键，并输入:wq并按下enter保存，退出，重启机器，验证成功。
