Oracle 自动启动脚本
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。N修改为Y
vi /etc/oratab
orcl:/ /home/oracle/app/oracle/product/11.2.0/dbhome_1:Y
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
修改vi /etc/init.d/oracle
如已存在需要检查
ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1
对不对。
不存在的话把以下内容加入：
#!/bin/sh
#chkconfig: 2345 20 80
#description: Oracle dbstart / dbshut
#以上两行为chkconfig所需
ORA_HOME=/home/ oracle /app/oracle/product/11.2.0/dbhome_1
ORA_OWNER= oracle
LOGFILE=/var/log/oracle.log
echo "#################################" >> ${LOGFILE}
date +"### %T %a %D: Run Oracle" >> ${LOGFILE}
if [ ! -f ${ORA_HOME}/bin/dbstart ] || [ ! -f ${ORA_HOME}/bin/dbshut ]; then
echo "Error: Missing the script file ${ORA_HOME}/bin/dbstart or ${ORA_HOME}/bin/dbshut!" >> ${LOGFILE}
echo "#################################" >> ${LOGFILE}
exit
fi
start(){
echo "###Startup Database..."
su - ${ORA_OWNER} -c "${ORA_HOME}/bin/dbstart ${ORA_HOME}"
echo "###Done."
echo "###Run database control..."
su - ${ORA_OWNER} -c "${ORA_HOME}/bin/emctl start dbconsole"
echo "###Done."
}
stop(){
echo "###Stop database control..."
su - ${ORA_OWNER} -c "${ORA_HOME}/bin/emctl stop dbconsole"
echo "###Done."
echo "###Shutdown Database..."
su - ${ORA_OWNER} -c "${ORA_HOME}/bin/dbshut ${ORA_HOME}"
echo "###Done."
}
case "$1" in
'start')
start >> ${LOGFILE}
;;
'stop')
stop >> ${LOGFILE}
;;
'restart')
stop >> ${LOGFILE}
start >> ${LOGFILE}
;;
esac
date +"### %T %a %D: Finished." >> ${LOGFILE}
echo "#################################" >> ${LOGFILE}
echo ""
3. 改变文件权限
chmod 755 /etc/init.d/oracle
4. 添加服务
chkconfig --level 35 oracle on
5. 测试
重启系统sqlplus查看
6. 使用方法
# service oracle start //启动oracle
# service oracle stop //关闭oracle
# service oracle restart //重启oracle
