                        Oracle Net8 网络配置和联接

１）服务器端配置Listener：
添加Listeners , 设置选择 DataBase Name方式，填写2个参数 { HomeDir = /ora/ ,
SID
２）启动Net8服务lsnrctl start
３）停止Net8服务lsnrctl stop
４）参数文件摘要
５）客户端配置：添加 Net Service Name ，同Windows客户端一样格式

１）服务器端配置Listener：

执行/ora/bin/netasst
填写描述->首选Oracle服务：

    。PROTOCOL = TCP
    。HOST = 172.17.2.22
    。PORT = 1521

查看生成的 Net8 Server配置文件：listener.ora
[oracle@lin admin]$ more listener.ora
# LISTENER.ORA Configuration File:/ora/network/admin/listener.ora
# Generated by Oracle Net8 Assistant
LISTENER =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.2.22)(PORT = 1521))
  (PROTOCOL_STACK =
    (PRESENTATION = TTC)
    (SESSION = NS)
  )
)

SID_LIST_LISTENER =
(SID_LIST =
  (SID_DESC =
   (ORACLE_HOME = /ora)
   (SID_NAME = ora8)
  )
)
### 如果指明监听服务的"全局名"，则有类似这一行：(GLOBAL_DBNAME = ora8)

２）启动Net8服务lsnrctl start

首先你可以这样取得帮助：
[oracle@lin /ora]$ lsnrctl
LSNRCTL> help
然后开始启动：start
[oracle@lin bin]$ lsnrctl start
联接时，机器会逐步告诉你正在启动…,正在联接…,已经联接的状态,最后他说成功啦!
下?
LSNRCTL for Linux: Version 8.1.5.0.0 - Production on 19-NOV-99 22:02:54

Starting /ora/bin/tnslsnr: please wait...

TNSLSNR for Linux: Version 8.1.5.0.0 - Production

))

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.2.22)(PORT=1521
))

STATUS of the LISTENER
------------------------
Alias LISTENER

Services Summary...
ora8 has 1 service handler(s)
The command completed successfully
以上提示说，1个服务被处理，命令成功完成。

３）停止Net8服务lsnrctl stop

最简单的方法是 [oracle@lin /ora]$ lsnrctl stop
有时侯，进程出了差错，tnslsnr没有响应，像WindowsNT常犯的毛病一样，
这里有一个强硬的手段：先找出它的进程号，然后 kill掉！
[oracle@lin /ora]$ ps -ef|grep tns
oracle 1331 1 0 15:51 ? 00:00:00 /ora/bin/tnslsnr LISTENER -inher

或使用更少的参数也能找到tnslsnr:
[oracle@lin /ora]$ ps -e
PID TTY TIME CMD
1331 ? 00:00:00 tnslsnr

现在杀死PID = 1331的进程：
[oracle@lin /ora]$ kill 1331
LSNRCTL象 SVRMGRL一样，是一个服务器管理程序，有不少参数，或者说是子程序，带星
号

[oracle@lin bin]$ lsnrctl stop
LSNRCTL for Linux: Version 8.1.5.0.0 - Production on 19-NOV-99 22:02:50
(c) Copyright 1998 Oracle Corporation. All rights reserved.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.2.22)(PORT=1521
))
(PROTOCOL_STACK=(PRESENTATION=TTC)(SESSION=NS)))
The command completed successfully

Listeners =DataBase Name = Global DB Name =ora8, HomeDir = /ora/ ,SID =ora8

[oracle@lin oracle]$ cd /ora/net*/ad*
[oracle@lin admin]$ ls
listener.ora namesini.sql samples sqlnet.ora
namesdrp.sql namesupg.sql sqlnet.fdf tnsnames.ora

下面是在 Windwos NT/98 上远程控制 TNSLSNR 的情形(图略)。

４）参数文件摘要

[oracle@lin admin]$ more /u01/app/oracle/admin/ora8/pfile/initora8.ora
db_name = ora8
instance_name = ora8 ## "事例名"是关键字
service_names = ora8

control_files = ("/u01/app/oracle/oradata/ora8/control01.ctl",
"/u01/app/oracle/
db_block_buffers = 8192
shared_pool_size = 4194304
log_checkpoint_interval = 10000
log_checkpoint_timeout = 1800
processes = 50
log_buffer = 163840

log_archive_start = true
log_archive_dest_1 = "location=/u01/app/oracle/admin/ora8/arch"
log_archive_format = %t_%s.dbf
# 切记打开回滚段
rollback_segments = (r01, r02, r03, r04)

# global_names = false ### 监听服务无需指明"全局名"
# oracle_trace_enable = true
# define directories to store trace and alert files
background_dump_dest = /u01/app/oracle/admin/ora8/bdump
core_dump_dest = /u01/app/oracle/admin/ora8/cdump
user_dump_dest = /u01/app/oracle/admin/ora8/udump
db_block_size = 2048
remote_login_passwordfile = exclusive
os_authent_prefix = ""
compatible = "8.1.5" ## 也可以兼容 "8.0.5"

5)客户端网络配置

[oracle@lin admin]$ more tnsnames.ora
# TNSNAMES.ORA Configuration File:/ora/network/admin/tnsnames.ora
# Generated by Oracle Net8 Assistant

使用net8助理,结果自动保存在 tnsnames.ora 中，
[oracle@lin /ora]$ netass* 添加Service: 名称ora8，参数如下：

PROTOCOL=TCP HOST=172.17.2.22 PORT=1521 Oracle_SID=ora8
机器解释成一个Oracle服务器地址包：
( DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.2.22)(PORT=1521))
  (PROTOCOL_STACK=(PRESENTATION=TTC)(SESSION=NS))
)
一般说来，客户端采用Windows9x/NT/2000,因为这里软件开发容易，程序员和工具较为普
及
Windows 客户端网络配置与此类似，其内容见于: \OraNT\net80\Admin\tnsname.ora
ORA8.WORLD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.2.22)(PORT = 1521))
    (CONNECT_DATA = (SID = ora8))
  )

-------------------------------------------
    在Windows2000(beta3专业版)中安装Personal Oeacle8.05时，监听服务安装失败，

只要理解以上oracle结构原理，可以手工复制Net8文件，修改配置：
copy CD-ROM\.\NT_x86\server\lsnrctl80.exe,tnslsnr80.exe,tnsping80.exe
C:\orant\
copy CD-ROM\.\listener.ora  C:\orant\net80\admin
我不久前有这么一次经历。
