配置和自动启动Oracle的监听(lsnrctl)(一)

配置Oracle lsnrctl 和自动启动

1.设置主机名称

[root@www ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=www.redhat6.com

2.设置主机名称与IP地址的对应

[root@www ~]# cat /etc/hosts
127.0.0.1    localhost localhost.localdomain localhost4 localhost4.localdomain4
::1          localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.16 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]$ lsnrctl

Welcome to LSNRCTL, type "help" for information.
LSNRCTL> help
The following operations are available
An asterisk (*) denotes a modifier or extended command:

start               stop                status

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::
#
# 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:N
orcl:/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.

[oracle@www ~]$ sqlplus / as sysdba
