linux下數(shù)據(jù)庫實例開機自啟動設置

1、修改/oratab

[root@org54 ~]# vi/etc/oratab --把N改為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創(chuàng)建庫時注冊的默認信息

--格式：$ORACLE_SID:$ORACLE_HOME:

--選項代表開機是否自啟動

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

2、編輯/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為開機自啟動腳本，讓系統(tǒng)開機就去執(zhí)行dbstart腳本文件，它會去讀oratab文件，讀到Y就會把對應的實例開機自啟動

--調(diào)整或確認監(jiān)聽路徑，如ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle或ORACLE_HOME_LISTNER=$ORACLE_HOME根據(jù)設置的監(jiān)聽調(diào)整路徑

3、編輯/rc.local

[root@org54 ~]# vi/etc/rc.d/rc.local --添加如下兩行信息，啟動實例、啟動監(jiān)聽

#!/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代表執(zhí)行腳本，腳本dbstart中指定啟動的實例，腳本lsnrctl中啟動配置的監(jiān)聽

4、重啟驗證

# reboot

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

小結：

linux下設置實例自啟動有關腳本：

oratab：實例是否自啟動的注冊信息

dbstart：開機啟動腳本文件會讀取oratab信息

rc.local：開機后立即要做的文件
