After installing Oracle 10g R2 under CentOS 6.3, after rebooting, you will find that Oracle does not start by itself, which is normal, because installing Oracle under Linux does not start by itself, you must set the relevant parameters by yourself, first introduce How to start oracle in general.
1. Start Oracle under Linux
Log in to CentOS and switch to oracle user authority
# su – oracle
Then enter:
$ sqlplus "/as sysdba"
The original screen will change to
SQL>
Then enter
SQL> startup
The database can be started normally.
In addition, the command to stop the database is as follows:
SQL> shutdown immediate
2. Check whether the Oracle DB listener is normal
Back in terminal mode, enter:
$ lsnrctl status
Check to see if the listener is started
If it doesn't start, you can enter:
$ lsnrctl start
start the listener
SQL> conn sys@orcl as sysdba
Then enter the password, and sys logs in to the database as sysdba.
3. Start emctl
In addition, it can also be found that http://localhost.localdomain:1158/em is currently unresponsive. It needs to be started separately here. The startup instructions are as follows:
$ emctl start dbconsole
This command runs for a long time, and the screen after execution is as follows:
After manually starting the Oracle database, create a script for the system to start Oracle by itself.
Fourth, Oracle start & stop script
1. Modify the Oracle system configuration file: /etc/oratab. Only in this way can Oracle's own dbstart and dbshut work.
# vi /etc/oratab
orcl:/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/102
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracle
echo "Done"
# Start the Listener:
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle
echo "Done."
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
touch /var/lock/subsys/oracle
;;
'stop')
# Stop the Oracle Listener:
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle
echo "Done."
rm -f /var/lock/subsys/oracle
# Stop the Oracle Database:
echo "Stoping Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracle
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
;;
'restart')
$0 stop
$0 start
;;
esac
3. 改变文件权限
# chmod 755 /etc/init.d/oracle
4. 添加服务
# chkconfig --level 35 oracle on
5. 需要在关机或重启机器之前停止数据库，做一下操作
# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //关机
# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重启
6. 使用方法
# service oracle start //启动oracle
# service oracle stop //关闭oracle
# service oracle restart //重启oracle
7. 测试
a. 开机自启动
