Linux配置Oracle 11g自動啓動

安裝完畢Oracle 11g每次都得手動啓動 | 停止數據庫（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，停止數據庫時停止監聽器），則需要修改dbstart腳本文件：

?

1 2	[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：

?

1 2 3 4 5 6 7 8

# First argument is used to bring up Oracle Net Listener ORACLE_HOME_LISTNER=$1       ### 需要將此處的 ORACLE_HOME_LISTNER=$1 修改爲 ORACLE_HOME_LISTNER=$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

同樣，修改dbshut：

?

1 2 3 4 5 6 7 8 9 10

[oracle@localhost ~]$ vi dbshut   # The  this to bring down Oracle Net Listener ORACLE_HOME_LISTNER=$1 ### 需要將此處的 ORACLE_HOME_LISTNER=$1 修改爲 ORACLE_HOME_LISTNER=$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，內容如下：

?

1 2	[oracle@localhost bin]$ cd /etc/init.d/ [oracle@localhost init.d]$ vi oracle

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46

#!/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：

?

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

建立鏈接：

?

1 2	[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：

?

1 2	[oracle@localhost init.d]$ chkconfig --level 345 oracle on [oracle@localhost init.d]$ chkconfig --add oracle

注意：

這樣的腳本一般不會啓動實例，如果想讓實例也隨腳本一起啓動的話，就需要修改文件/etc/oratab 
如果這個文件不存在，就要運行腳本文件產生它。

?

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

# 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

可以看出，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，即可實現自動啓動。
