监听的动态注册问题

原创 Linux操作系统 作者:parameters 时间:2011-08-19 11:46:31 0 删除 编辑
新装的测试服务器,使用plsql 远程连接时报 tns连接超时,感觉应该是问题出在服务器的监听上;
查看监听状态:
-----------------------------------------------------------------------------------------------------------------
[oracle@localhost ~]$ lsnrctl start

The command completed successfully
--------------------------------------------------------------------------------------------------------------
查看listener.ora
[oracle@localhost admin]$ cat listener.ora
# listener.ora Network Configuration File: /install//network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /install/)
#      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.72.5 )(PORT = 1521))
    )
  )
为动态注册;
-------------------------------------------------------------------------------
查看tns文件:
PARAMTER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.5)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = parameter)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
---------------------------------------------------------------
查看监听的参数:
SQL> show parameters local_listener

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string     
为空

首先修改 tnsname.ora 文件为:
[oracle@localhost ~]$ cat /install/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /install/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.5)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = parameter)
    )
  )
---------------------------------------------------------------------------------------------------------------
在sqlplus中,修改参数:
SQL> alter system set local_listener=LISTENER;
System altered.

此时查看监听的状态:
[oracle@localhost ~]$ lsnrctl stat
