Oracle 数据库和监听器开机自启动两种实现方法

数据库和监听器开机自启动

 

编辑oratab文件：

修改：orcl:/u01/app/oracle/product/11.2.0/db_1:N

           orcl:/u01/app/oracle/product/11.2.0/db_1:Y

[oracle@ocptest bin]$ vi /etc/oratab
#
 
 
# 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/11.2.0/db_1:Y

　　

　　

执行dbstart和dbshut（数据库启动而监听器没有自启动）

[oracle@ocptest ~]$ dbstart
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Usage: /u01/app/oracle/product/11.2.0/db_1/bin/dbstart ORACLE_HOME
Processing Database instance "orcl": log file /u01/app/oracle/product/11.2.0/db_1/startup.log

　　

 

修改dbstart和dbshut文件：

[oracle@ocptest ~]$ cd $ORACLE_HOME/bin
[oracle@ocptest bin]$ vi dbstart

　　

 

找到这行修改为：

ORACLE_HOME_LISTNER=$1
ORACLE_HOME_LISTNER=$ORACLE_HOME

同上修改dbshut文件。

 

dbstart验证：

[oracle@ocptest bin]$ dbstart
Processing Database instance "orcl": log file /u01/app/oracle/product/11.2.0/db_1/startup.log
[oracle@ocptest bin]$ ps -ef|grep smon

dbshut验证：

[oracle@ocptest bin]$ dbshut
Processing Database instance "orcl": log file /u01/app/oracle/product/11.2.0/db_1/shutdown.log
[oracle@ocptest bin]$ ps -ef|grep smon

添加开机自启动：

编辑/etc/rc.d/rc.local添加su oracle -lc /u01/app/oracle/product/11.2.0/db_1/bin/dbstart 到最后一行

[oracle@ocptest ~]$ vi /etc/rc.d/rc.local
#!/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.
 
 
 
 
touch /var/lock/subsys/local
su oracle -lc /u01/app/oracle/product/11.2.0/db_1/bin/dbstart

如果上面没有编辑dbstart和dbshut文件添加侦听器参数：

则还需添加 su oracle -lc "/u01/oracle/bin/lsnrctl start"到/etc/rc.d/rc.local文件中；

 

 

第二种方法：

在oracle家目录创建两个文件：

oracle.start

oracle.stop

编辑：

vi oracle.start

[oracle@ocptest ~]$ vi oracle.start
#!/bin/bash
source /u01/app/oracle/product/11.2.0/db_1
lsnrctl start;
sqlplus / as sysdba <<EOF
startup
EOF

　　

vi oracle.stop

[oracle@ocptest ~]$ vi oracle.stop
#!/bin/bash
source /u01/app/oracle/product/11.2.0/db_1
sqlplus / as sysdba <<EOF
startup
EOF
lsnrctl stop;

　

权限：

chmod +x /etc/init.d/oracle

chmod a+x oracle.start oracle.stop

 

单独执行这两个脚本进行验证；

 

通过copy一个network模板

cp /etc/init.d/network /etc/init.d/oracle
[root@ocptest ~]# vi /etc/init.d/oracle
#! /bin/bash
#
# oracle       Bring up/down oracle
#
# chkconfig: 2345 90 1
# description: Activates/Deactivates all oracle configured to \
#              start at boot time.
#
# Source function library.
. /etc/init.d/functions
 
 
# See how we were called.
case "$1" in
  start)
        su - oracle -c "/home/oracle/oracle.start"
        ;;
  stop)
        su - oracle -c "/home/oracle/oracle.stop"
        ;;
  *)
        echo $"Usage: $0 {start|stop}"
        exit 2
esac

chkconfig oracle on

 然后重启服务器测试下，我这里测试都没问题。

 

验证端口：

[oracle@ocptest ~]$ netstat -an|grep :1521
tcp        0      0 192.168.181.2:62747         192.168.181.2:1521          ESTABLISHED
