linux下数据库实例开机自启动设置

1、修改/oratab

[root@org54 ~]# vi/etc/oratab --把n改为y，如下提示

# This file is used by ORACLEutilities. It is created by root.sh

# and updated by the Database ConfigurationAssistant when creating

# a database.

# A colon, ':', is used as the fieldterminator. A new line terminates

# the entry. Lines beginning with a pound sign, '#', arecomments.

#

# Entries are of the form:

# $ORACLE_SID:$ORACLE_HOME::

#

# The first and second fields are thesystem identifier and home

# directory of the databaserespectively. The third filed indicates

# to the dbstart utility that the databaseshould , "Y", or should not,

# "N", be brought up at systemboot time.

#

# Multiple entries with the same$ORACLE_SID are not allowed.

#

#

#game:/u01/app/oracle/product/10.2.0/db_1:N --dbca创建库时注册的默认信息

--格式：$ORACLE_SID:$ORACLE_HOME:

--选项代表开机是否自启动

game:/u01/app/oracle/product/10.2.0/db_1:Y

2、编辑/dbstart

[oracle@org54 bin]$ cd$ORACLE_HOME/bin

[oracle@org54 bin]$ ls-ll |grep dbstart

-rwxr-xr-x 1 oracle oinstall 10415 Jan 1 2000 dbstart

[oracle@org54 bin]$ vidbstart

--dbstart为开机自启动脚本，让系统开机就去执行dbstart脚本文件，它会去读oratab文件，读到Y就会把对应的实例开机自启动

--调整或确认监听路径，如ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle或ORACLE_HOME_LISTNER=$ORACLE_HOME根据设置的监听调整路径

3、编辑/rc.local

[root@org54 ~]# vi/etc/rc.d/rc.local --添加如下两行信息，启动实例、启动监听

#!/bin/sh

#

# This script will be executed *after* allthe other init scripts.

# You can put your own initialization stuffin here if you don't

# want to do the full Sys V style initstuff.

touch /var/lock/subsys/local

modprobe hangcheck-timer hangcheck_tick=30hangcheck_margin=180

su - oracle -c"/u01/app/oracle/product/10.2.0/db_1/bin/dbstart"

su - oracle -c"/u01/app/oracle/product/10.2.0/db_1/bin/lsnrctl start"

--命令中-c代表执行脚本，脚本dbstart中指定启动的实例，脚本lsnrctl中启动配置的监听

4、重启验证

# reboot

[oracle@org54 ~]$ sqlplus'/as sysdba'

小结：

linux下设置实例自启动有关脚本：

oratab：实例是否自启动的注册信息

dbstart：开机启动脚本文件会读取oratab信息

rc.local：开机后立即要做的文件
