在CentOS 6.3下安装完Oracle 10g R2,重开机之后,你会发现Oracle没有自行启动,这是正常的,因为在Linux下安装Oracle的确不会自行启动,必须要自行设定相关参数,首先先介绍一般而言如何启动oracle。
一、在Linux下启动Oracle
登录到CentOS,切换到oracle用户权限
# su oracle
接着输入:
$ sqlplus "/as sysdba"
原本的画面会变为
SQL>接着请输入
SQL> startup就可以正常的启动数据库了。
另外停止数据库的指令如下:
SQL> shutdown immediate
二、检查Oracle DB监听器是否正常
回到终端机模式,输入:
$ lsnrctl status
检查看看监听器是否有启动
如果没有启动,可以输入:
$ lsnrctl start
启动监听器
SQL> conn sys@orcl as sysdba
然后输入密码,sys以sysdba身份登入数据库。
三、启动emctl
另外也可以发现http://localhost.localdomain:1158/em 目前是没有反应的,这边要另外启动,启动的指令如下:
$ emctl start dbconsole
这个指令运行时间较长,执行完的画面如下:
手动启动Oracle数据库完毕,下面创建系统自行启动Oracle的脚本。
四、Oracle启动&停止脚本
1. 修改Oracle系统配置文件:/etc/oratab,只有这样,Oracle 自带的dbstart和dbshut才能够发挥作用。
# vi /etc/orataborcl:/opt/oracle/102:Y# Entries are of the form:# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
2. 在 /etc/init.d/ 下创建文件oracle,内容如下:
#!/bin/sh# chkconfig: 35 80 10# description: Oracle auto start-stop script.## Set ORA_HOME to be equivalent to the $ORACLE_HOME# from which you wish to execute dbstart and dbshut;## Set ORA_OWNER to the user id of the owner of the# Oracle database in ORA_HOME.ORA_HOME=/opt/oracle/102ORA_OWNER=oracleif [ ! -f $ORA_HOME/bin/dbstart ]then echo "Oracle startup: cannot start" exitficase "$1" in'start')# Start the Oracle databases:echo "Starting Oracle Databases ...
