怎么把开机oracle,怎么把开机pin密码去掉

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/product/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/product/11.2.0/dbhome_1:Y

#####Finished wrote in 2015-12-24

说明：/home/oracle/app/oracle/product/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/product/11.2.0/dbhome_1:N

复制该行oel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N并注释掉

粘贴该行，并将该行

oel63:/home/oracle/app/oracle/product/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/product/11.2.0/dbhome_1/bin/lsnrctl start"

su oracle -lc /home/oracle/app/oracle/product/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/product/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。

是不是很简单呢~快跟着我一起学习吧!!!如果觉得这篇 文章 不错的话就给我点一个赞吧。

oracle开机自启动

1) 建立用户， 组， 目录

[root@node1 ~]# id oracle

id: oracle: No such user

[root@node1 ~]# groupadd -g 54321 oinstall

[root@node1 ~]# groupadd -g 54322 dba

[root@node1 ~]# useradd -u 54321 -g oinstall -G dba oracle

[root@node1 ~]# passwd oracle

Changing password for user oracle.

New password:

BAD PASSWORD: it is based on a dictionary word

BAD PASSWORD: is too simple

Retype new password:

passwd: all authentication tokens updated successfully.

[root@node1 ~]# mkdir -p /u01/app/oracle

[root@node1 ~]# chown -R oracle:oinstall /u01/

2) 环境变量

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export ORACLE_SID=ora11g

export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

LANG=C

3) Cat /etc/sysctl.conf

kernel.shmmax = 4294967295

kernel.shmall = 2097152

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 6815744

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default=1048576

net.core.rmem_max=4194304

net.core.wmem_default=262144

net.core.wmem_max=1048576

fs.aio-max-nr=1048576

4) oracle 开机自启

[root@node1 ~]# cp /etc/init.d/network /etc/init.d/oracle

[root@node1 ~]# vim /etc/init.d/oracle

[root@node1 ~]# chmod +x /etc/init.d/oracle

[root@node1 ~]# chkconfig oracle on

[root@node1 ~]# cat /etc/init.d/oracle

[oracle@node1 auto_backup]$ cat /etc/init.d/oracle

#! /bin/bash#

chkconfig: 2345 10 90

#

Source function library.

. /etc/init.d/functions

# See how we were called.

case "$1" in

start)

su - oracle -c "/home/oracle/startdb11g"

;;

stop)

su - oracle -c "/home/oracle/stopdb11g"

;;

*)

echo #34;Usage: $0 {start|stop}"

exit 2

esac

exit $rc

[oracle@node1 auto_backup]$ chkconfig oracle on

取消Oracle开机自动启动

1.右键我的电脑-管理-服务和应用程序-服务

2.找到Oracle打头的几个服务(如图)，最占用资源的是OracleServiceDB

右键OracleServiceDB-属性-状态-停止即可停止oracle.exe服务但是下次电脑开机后会自动启动(右键OracleServiceDB-属性-启动类型-手动该服务以后不自动开启。需要使用oracle的时候手动点击启动按钮“属性-服务状态-启动”)

3.其它服务可按照该方法依次停止服务。希望能对你有帮助!
