Linux/Unix 中如何配置 Oracle Database 随服务器自动启动
Oracle Database 软件提供了以下两个脚本来配置数据库随服务器自动启动和关闭：
[oracle@prod bin]$ pwd
/u01/app/oracle/product/11.2.0/db_1/bin
[oracle@prod bin]$ ls -l dbs*
-rwxr-x--- 1 oracle oinstall  6030 Jan  1  2000 dbshut
-rwxr-x--- 1 oracle oinstall 13797 Jan  1  2000 dbstart


我们需要在 unix 启动/关闭脚本（ rc0.d / rc1.d 等）中调用这两个脚本

1、检查 /etc/oratab 下的 oratab 文件，该文件应该包含要设置自动启动和关闭的数据库的条目，
其中 autostart 值域的值为 Y，如下所示：
$ORACLE_SID:$ORACLE_HOME:Y

[oracle@prod bin]$ more /etc/oratab
prod:/u01/app/oracle/product/11.2.0/db_1:N

[oracle@prod bin]$ vi /etc/oratab
prod:/u01/app/oracle/product/11.2.0/db_1:Y

2、将如下文件保存到 /etc/init.d/ 下（/etc/init.d/ 是 redhat linux 下特有的）。

[root@prod init.d]# pwd
/etc/init.d
[root@prod init.d]# ls -l dbora
-rw-r--r-- 1 root root 1049 Mar 27 20:10 dbora


--注意 ORA_OWNER 和 ORA_HOME 变量的设置

------------------ Start dbora ---------------------------------

#! /bin/bash
#
# description: Oracle auto start-stop script.
#
# chkconfig: 2345 99 10 
#
# processname: oracle
# config: /etc/oratab
# pidfile: /var/run/oracle.pid

# Source function library.
. /etc/init.d/functions

RETVAL=0
ORA_OWNER="oracle"
ORA_HOME="/u01/app/oracle/product/11.2.0/db_1"

# See how we were called.

prog="oracle"

start() {
echo -n $"Starting $prog: "
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" 
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/dbora

return $RETVAL
}

stop() {
echo -n $"Stopping $prog: "
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" 
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -r /var/lock/subsys/dbora

return $RETVAL
} 

restart() {
stop
start
} 

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac

exit $?

------------------ End dbora ---------------------------------


3: 以 root 用户身份执行如下命令：

[root@prod init.d]# cd /sbin
[root@prod sbin]# chkconfig --add dbora
--此命令将创建如下系统服务
[root@prod sbin]# chkconfig --list | grep dbora
dbora           0:off   1:off   2:on    3:on    4:on    5:on    6:off


--此外，还会创建如下文件
/etc/rc2.d/S99dbora ( calls $ORACLE_HOME/bin/dbstart )
/etc/rc3.d/S99dbora ( calls $ORACLE_HOME/bin/dbstart )
/etc/rc4.d/S99dbora ( calls $ORACLE_HOME/bin/dbstart )
/etc/rc5.d/S99dbora ( calls $ORACLE_HOME/bin/dbstart )

/etc/rc0.d/K10dbora ( calls $ORACLE_HOME/bin/dbshut )
/etc/rc1.d/K10dbora ( calls $ORACLE_HOME/bin/dbshut )
/etc/rc6.d/K10dbora ( calls $ORACLE_HOME/bin/dbshut )
