Linux 下Oracle 开机自启动 与 oratab， dbstart 脚本 说明

一./etc/oratab说明

直接使用cat 查看这个文件：

gg1:/home/oracle> cat /etc/oratab
#
 
# 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.
#
#
gg1:/u01/app/oracle/product/11.2.0.3/db_1:N

这里是我测试环境上的文件，在这个注释里面，对这个文件讲的比较清楚。/etc/oratab 由root.sh 脚本创建，在用DBCA 创建实例时也会更新这个文件。

当$ORACLE_SID:$ORACLE_HOME: 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。

所以配置数据库自启动和关闭的步骤如下：

（1） 配置/etc/oratab

（2） 修改$ORACLE_HOME/bin/dbstart和dbshut，并将其添加到/etc/rc(.local) 文件中。

这里是使用oracle 自带的dbstart 和dbshut脚本，如果使用自己写的脚本来启动或关闭DB 就不需要关心这个文件的设置了。

二.$ORACLE_HOME/bin/dbstart，dbshut 说明

2.1 dbstart 脚本

#
# usage: dbstart $ORACLE_HOME
#
# This script is used tostart ORACLE from /etc/rc(.local).
# It should ONLY beexecuted as part of the system boot procedure.
#
# This script will start all databaseslisted in the oratab file
# whose third field is a"Y".  If the third field is setto "Y" and
# there is no ORACLE_SID for an entry (thefirst field is a *),
# then this script will ignore that entry.
--这里就是我们之前说的，这个仅启动/etc/oratab 文件中标记为Y的实例。
#
# This script requires that ASMORACLE_SID's start with a +, and
# that non-ASM instance ORACLE_SID's do notstart with a +.
#
# If ASM instances are to be started withthis script, it cannot be used inside an rc*.d directory, and should be invokedfrom rc.local only. Otherwise, the CSS service may not be available yet, andthis script will block init from completing the boot cycle.
--如果是ASM 实例，那么只能从rc.local中调用，否则CSS 服务可能不可用。
#
# If you want dbstart to auto-start asingle-instance database that uses
# an ASM server that is auto-started by CRS(this is the default behavior
# for an ASM cluster), you must change thedatabase's ORATAB entry to use
# a third field of "W" and theASM's ORATAB entry to use a third field of "N".
# These values specify that dbstartauto-starts the database only after
# the ASM instance is up and running.
--注意这里的W，其表示等待所有的ASM 实例启动完毕后在启动数据库。
#
# Note:
# Use ORACLE_TRACE=T for tracing thisscript.
#
# The progress log for each instancebringup plus Error and Warning message[s]
# are logged in file $ORACLE_HOME/startup.log.The error messages related to
# instance bringup are also logged tosyslog (system log module).
# The Listener log is located at$ORACLE_HOME_LISTNER/listener.log
--启动日志存放在$ORACLE_HOME/startup.log里。
#
# On all UNIX platforms except SOLARIS
# ORATAB=/etc/oratab
#
# To configure, update ORATAB withInstances that need to be started up
#   Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME::
#   An example entry:
#   main:/usr/lib/oracle/emagent_10g:Y
#
# Overall algorithm:
--启动顺序
# 1) Bring up all ASM instances with 'Y'entry in status field in oratab entry
--启动状态为Y的所有ASM 实例
# 2) Bring up all Database instances with'Y' entry in status field in
#   oratab entry
--启动所有状态为Y的数据库实例
# 3) If there are Database instances with'W' entry in status field
#   then
#     iterate over all ASM instances (irrespective of 'Y' or 'N') AND
#     wait for all of them to be started
#   fi
--如果数据库的状态为W，则等待ASM 实例启动完毕，再启动
# 4) Bring up all Database instances with'W' entry in status field in
#   oratab entry
--启动所有状态为W的数据库实例

通过以上信息，我们可以看出，我们只需要修改/etc/oratab脚本就可以了，dbstart 和dbshut命令可以从/etc/oratab里获取需要的参数值。

三.DB 开机自启动示例

3.1 修改/etc/oratab的值为Y

gg1:/u01/app/oracle/product/11.2.0.3/db_1/bin>ll /etc/oratab

-rw-rw-r-- 1 oracle oinstall 722 Jan 3020:36 /etc/oratab

gg1:/u01/app/oracle/product/11.2.0.3/db_1/bin>cat /etc/oratab

#

gg1:/u01/app/oracle/product/11.2.0.3/db_1:Y

3.2 修改dbstart的ORACLE_HOME_LISTNER，使其指向$ORACLE_HOME:

# First argument is used to bring up OracleNet Listener

ORACLE_HOME_LISTNER=$ORACLE_HOME

3.3 用root用户在rc.local里添加如下内容：

[root@gg1 ~]# cat /etc/rc.local

#!/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

su - oracle -c"/u01/app/oracle/product/11.2.0.3/db_1/bin/dbstart"

su - oracle -c"/u01/app/oracle/product/11.2.0.3/db_1/bin/emctl start dbconsole"

这里注意必须用oracle 用户来启动脚本。

3.4 reboot 系统，Oracle就自动启动了。

在我们的配置中，启动的包括监听，实例和OEM。

启动日志如下：
