Linux配置Oracle 11g自動啓動

http://www.cnblogs.com/edwardcmh/archive/2012/05/11/2495671.html

安裝完畢Oracle 11g每次都得手動啓動 | 中止數據庫（dbstart | dbshut）、監聽器（lsnrctl）、控制檯（emtcl）。

設置一下，若手動啓動數據庫的同時監聽器沒有啓動（即啓動數據庫時自動啓動監聽器，中止數據庫時中止監聽器），則須要修改dbstart腳本文件：

[oracle@localhost ~]$ cd /u01/app/oracle/product/11.1.0/db_1/bin/
[oracle@localhost ~]$ vi dbstart

找到下面的代碼段：

# First argument is used to bring up Oracle Net Listener
ORACLE_HOME_LISTNER=$1       
### 須要將此處的 ORACLE_HOME_LISTNER=$1 修改成 ORACLE_HOME_LISTNER=$ORACLE_HOME
if [ ! $ORACLE_HOME_LISTNER ] ; then
  echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
  echo "Usage: $0 ORACLE_HOME"
else
  LOG=$ORACLE_HOME_LISTNER/listener.log

一樣，修改dbshut：

[oracle@localhost ~]$ vi dbshut

# The  this to bring down Oracle Net Listener
ORACLE_HOME_LISTNER=$1
### 須要將此處的 ORACLE_HOME_LISTNER=$1 修改成 ORACLE_HOME_LISTNER=$ORACLE_HOME
if [ ! $ORACLE_HOME_LISTNER ] ; then
  echo "ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener"
  echo "Usage: $0 ORACLE_HOME"
else
  LOG=$ORACLE_HOME_LISTNER/listener.log

完成後配置Linux啓動腳本oracle，內容以下：

[oracle@localhost bin]$ cd /etc/init.d/
[oracle@localhost init.d]$ vi oracle

#!/bin/sh
# chkconfig: 345 61 61
# description: Oracle 11g AutoRun Services
# /etc/init.d/oracle
#
# Run-level Startup script for the Oracle Instance, Listener, and
# Web Interface

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
export ORACLE_SID=ORCL
export PATH=$PATH:$ORACLE_HOME/bin

ORA_OWNR="oracle"

# if the executables do not exist -- display error

if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
     echo "Oracle startup: cannot start"
     exit 1
fi

# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display

case "$1" in
 start)
     # Oracle listener and instance startup
     su $ORA_OWNR -lc $ORACLE_HOME/bin/dbstart
     echo "Oracle Start Succesful!OK."
     ;;
 stop)
     # Oracle listener and instance shutdown
     su $ORA_OWNR -lc $ORACLE_HOME/bin/dbshut
     echo "Oracle Stop Succesful!OK."
     ;;
 reload|restart)
     $0 stop
     $0 start
     ;;
 *)
     echo $"Usage: `basename $0` {start|stop|reload|reload}"
     exit 1
esac
exit 0

賦予腳本可執行權限：

[oracle@localhost init.d]$ chmod 750 /etc/init.d/oracle

創建連接：

[oracle@localhost init.d]$ ln -s /etc/init.d/oracle /etc/rc1.d/K61oracle
[oracle@localhost init.d]$ ln -s /etc/init.d/oracle /etc/rc3.d/S61oracle

啓用腳本並添加到服務：

[oracle@localhost init.d]$ chkconfig --level 345 oracle on
[oracle@localhost init.d]$ chkconfig --add oracle

注意：

這樣的腳本通常不會啓動實例，若是想讓實例也隨腳本一塊兒啓動的話，就須要修改文件/etc/oratab 
若是這個文件不存在，就要運行腳本文件產生它。

[root@localhost init.d]# $ORACLE_HOME/root.sh

# 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.
#
#

orcl:/u01/app/oracle/product/11.1.0/db_1:Y

能夠看出，實例orcl是自動啓動的（標識爲Y），只要在這裏配置好，再配合上面的腳本，便可實現自動啓動。
