配置和自动启动Oracle的监听(lsnrctl)

配置Oracle lsnrctl 和自动启动

1.设置主机名称

[root@www ~]# cat /etc/sysconfig/networkNETWORKING=yesHOSTNAME=www.redhat6.com

2.设置主机名称与IP地址的对应

[root@www ~]# cat /etc/hosts127.0.0.1    localhost localhost.localdomain localhost4 localhost4.localdomain4::1          localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.2.16 www.redhat6.com

3.修改:/u01/app/oracle/network/admin/listener.ora

[oracle@www admin]$ cat listener.ora # listener.ora Network Configuration File: /u01/app/oracle/network/admin/listener.ora# Generated by Oracle configuration tools.LISTENER =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = www.redhat6.com)(PORT = 1521))    )  )ADR_BASE_LISTENER = /u01/app

4.修改:/u01/app/oracle/network/admin/tnsnames.ora

[oracle@www admin]$ cat tnsnames.ora # tnsnames.ora Network Configuration File: /u01/app/oracle/network/admin/tnsnames.ora# Generated by Oracle configuration tools.ORCL =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = www.redhat6.com)    )  )

5.lsnrctl 的常用方法

[oracle@www admin]$ lsnrctlLSNRCTL for Linux: Version 11.2.0.3.0 - Production on 29-NOV-2013 21:56:57Copyright (c) 1991, 2011, Oracle.  All rights reserved.Welcome to LSNRCTL, type "help" for information.LSNRCTL> helpThe following operations are availableAn asterisk (*) denotes a modifier or extended command:start               stop                status              services            version             reload              save_config         trace               spawn               change_password     quit                exit                set*                show* 

lsnrctl start  -- 启动监听
lsnrctl stop   -- 停止监听
lsnrctl status -- 查看状态

6.设置Oracle数据库和lsnrct自动启动方法

(我的机器是RedHat6_64,Oracle11g)

6.1.编辑: /etc/oratab

[root@www ~]# cat /etc/oratab ## This file is used by ORACLE utilities.  It is created by root.sh# and updated by either Database Configuration Assistant while creating# a database or ASM Configuration Assistant while creating ASM instance.# 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:Norcl:/u01/app/oracle:Y    #这里把"N"改为"Y"

6.2.修改 /etc/rc.local

[root@www ~]# cat /etc/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# 添加下面两条su - oracle -c 'dbstart'su - oracle -c 'lsnrctl start'

6.3.重新启动系统.Oracle数据库正常启动.监听也启动了.

其它问题:

关闭linux防火墙:

暂时关闭:service iptables stop永久性,需重启:chkconfig iptables off[root@www ~]# chkconfig --list | grep iptablesiptables       0:off1:off2:on3:on4:on5:on6:off[root@www ~]# chkconfig iptables off[root@www ~]# chkconfig --list | grep iptablesiptables       0:off1:off2:off3:off4:off5:off6:off

关闭selinux:

1 永久方法 – 需要重启服务器修改/etc/selinux/config文件中设置SELINUX=disabled ，然后重启服务器。2 临时方法 – 设置系统参数使用命令setenforce 0附：setenforce 1 设置SELinux 成为enforcing模式setenforce 0 设置SELinux 成为permissive模式
