Linux下設定Oracle自啟動

測試機總是斷電，導致重啟後Oracle不自動重啟，需要手工操作，因此可以設定成自啟動模式。

作業系統：Linux

資料庫：Oracle 10g

1、vi /etc/oratab

找到bisal:/opt/oracle/102:N，將N設為Y。

檔案的註釋：

# 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::
#
# 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.

可以看到這裡$ORACLE_SID是bisal，$ORACLE_HOME是/opt/oracle/102。

設定為Y時，允許例項自啟動，當設定為N時，則不允許自啟動。 

這個檔案裡的配置僅僅起一個開關的作用，其並不會具體的執行啟動和關閉，具體的操作由$ORACLE_HOME/bin/dbstart和dbshut 指令碼來實現。 這2個指令碼在執行時會檢查/etc/oratab 檔案裡的配置，為Y時才能繼續執行。

2、將lsnrctl start和dbstart新增到rc.local檔案中：

vi /etc/rc.d/rc.local

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

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

檔案：

#!/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.

此處也可以使用自己定義的指令碼作為啟動指令碼。

然後重啟伺服器，就可以看到監聽和例項都可以自動啟動了。
