Linux下设置Oracle自启动

测试机总是断电，导致重启后Oracle不自动重启，需要手工操作，因此可以设置成自启动模式。

操作系统：Linux

数据库：Oracle 10g

1、vi /etc/oratab

找到bisal:/opt/oracle/102:N，将N设为Y。

文件的注释：

# This file is used by ORACLE utilities.  It is created by root.sh # and updated by the Database Configuration Assistant when creating # a database. # A colon, ':', is used as the field terminator.  A new line terminates # the entry.  Lines beginning with a pound sign, '#', are comments. # # Entries are of the form: #   $ORACLE_SID:$ORACLE_HOME:<N|Y>: # # The first and second fields are the system identifier and home # directory of the database respectively.  The third filed indicates # to the dbstart utility that the database should , "Y", or should not, # "N", be brought up at system boot time. # # Multiple entries with the same $ORACLE_SID are not allowed.

可以看到这里$ORACLE_SID是bisal，$ORACLE_HOME是/opt/oracle/102。

设置为Y时，允许实例自启动，当设置为N时，则不允许自启动。 

这个文件里的配置仅仅起一个开关的作用，其并不会具体的执行启动和关闭，具体的操作由$ORACLE_HOME/bin/dbstart和dbshut 脚本来实现。 这2个脚本在执行时会检查/etc/oratab 文件里的配置，为Y时才能继续执行。

2、将lsnrctl start和dbstart添加到rc.local文件中：

vi /etc/rc.d/rc.local

su oracle -lc "/opt/oracle/102/bin/lsnrctl start"

su oracle -lc  /opt/oracle/102/bin/dbstart

文件：

#!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff.

此处也可以使用自己定义的脚本作为启动脚本。

然后重启服务器，就可以看到监听和实例都可以自动启动了。
