Linux Oracle数据库开机启动
#!/bin/bash #start Oracle server lsnrctl start echo $'startup\nexit' > /home/oracle/start_Oracle.sql sqlplus / as sysdba @/home/oracle/start_Oracle.sql
?
?
脚本只有简简单单的五行内容，那么我们来简单了解一下吧！
?
第一行：告诉kernel我们使用的解释器为Bash
#!/bin/bash
?
?
第二行：简单的提示信息，便于后期维护
#start Oracle server?
?
?
第三行：启动数据库监听
lsnrctl start
?
??
第四行：将启动数据库需要的SQL语句输入至 /home/oracle/start_Oracle.sql数据库脚本中，后续我们需要调用此脚本
echo $'startup\nexit' > /home/oracle/start_Oracle.sql
?
?
/home/oracle/start_Oracle.sql的内容
startupexit
?
?
第五行：调用我们刚刚生成的SQL语句，格式是：“sqlplus /as sysdba”连接数据库“@”后边加上SQL脚本
sqlplus / as sysdba @/home/oracle/start_Oracle.sql
?
?
二、开机启动
?
加入系统开机执行
# vi /etc/rc.local增加su - oracle -s /bin/bash /home/oracle/start_Oracle.sh
?
因为我使用的是root来执行此脚本，所以当开机启动的时候需要切换到Oracle用户才好
?
?
三、功能测试
?
重新启动检测是否成功，可能要等段时间，linux开机也需要加载些别的东西
# reboot
?
?
查看数据库是否启动成功
