Linux下Oracle 10g自动启动与关闭的实现

环境：RHEL 5.5 + Oracle 10g + VMWare 5.5

尝试在linux下进行oracle的自动启动与关闭，经过多次摸索，完整实现如下：

1、修改oratab文件，使数据库自动启动

#vi /etc/oratab

sid:/opt/app/ora10g/oracle/product/10.2.0/db_1:Y -----即把原来的N修改为Y。

2、修改dbstart、dbshut脚本，使之能够自动启动、关闭LISTENER

将dbstart与dbshut两个脚本中的ORACLE_HOME_LISTNER=$1改为

ORACLE_HOME_LISTNER=$ORACLE_HOME即可（我这个版本好像只修改dbstart,dbshut中没有什么要修改）

3、编写启动脚本/etc/rc.d/init.d/oracle

#!/bin/bash
#

restart)
$0 stop
$0 start

;;

echo "Usage: oracle {start|stop|restart}"
exit 1
esac
exit 0

4、添加服务
[root@by init.d]# chmod 755 oracle
[root@by init.d]# chmod +x /etc/rc.d/init.d/oracle
[root@by init.d]# chkconfig --add oracle
[root@by init.d]# chkconfig --list oracle
oracle 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

如果出现：bash: chkconfig: command not found，那么一般是chkconfig包没装或者装了路径没设置对。

[root@by init.d]# PATH="$PATH":/sbin
[root@by init.d]# echo $PATH
/sbin:/usr/kerberos/sbin:/opt/oracle/product/10.2.0/db_1/bin:/usr/sbin:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin:/sbin

5、测试服务

[root@by init.d]# service oracle stop

如果出现如下错误：
Stoping EM ...
/home/oracle/.bash_profile: line 23: ulimit: open files: cannot modify limit: 不允许的操作
Done.

可在

[root@by init.d]# vi /etc/security/limits.conf
添加如下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

Ok，一切完成。关闭系统，重启，最后验证，都自动启动了。
