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 =ora8 } 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Wind

  
  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 =ora8 }
  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! 下面是一些简要信息:
  LSNRCTL for Linux: Version 8.1.5.0.0 - Production on 19-NOV-99 22:02:54
  (c) Copyright 1998 Oracle Corporation. All rights reserved.
  Starting /ora/bin/tnslsnr: please wait...
  TNSLSNR for Linux: Version 8.1.5.0.0 - Production
  System parameter file is /ora/network/admin/listener.ora
  Log messages written to /ora/network/log/listener.log
  Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.2.22)(PORT=1521))
  (PROTOCOL_STACK=(PRESENTATION=TTC)(SESSION=NS)))
  
  Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.2.22)(PORT=1521))
  (PROTOCOL_STACK=(PRESENTATION=TTC)(SESSION=NS)))
  STATUS of the LISTENER
  ------------------------
  Alias LISTENER
  Version TNSLSNR for Linux: Version 8.1.5.0.0 - Production
  Start Date 19-NOV-99 22:02:54
  Uptime 0 days 0 hr. 0 min. 0 sec
  Trace Level off
  Security OFF
  SNMP OFF
  Listener Parameter File /ora/network/admin/listener.ora
  Listener Log File /ora/network/log/listener.log
  Services Summary...
  ora8 has 1 service handler(s)
  The command completed suclearcase/" target="_blank" >ccessfully
  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,带星号的是一个外部程序。
  [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/oradata/ora8/control02.ctl")
  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\bin
  copy CD-ROM\.\listener.ora C:\orant\net80\admin
  我不久前有这么一次经历。
