PS:不晓得,大家有没有像我这样折腾,俺总喜欢关闭不是总用到的服务,等用到时再手动启动,此外经常更换ip地址
系统环境:Windows 2003 Ent R2 CHS 32bit,Oracle 11.2.0.1.0 R2
下面操作默认在安装Oralce数据库的服务器上运行。
1)确保Oracle 基本服务都已启动
OracleDBConsoleorcl
OracleOraDb11g_home1TNSListener
OracleServiceORCL
2)打开命令行,使用 sqlplus nokia_user/oracle@202.206.0.233/orcl 命令登录 oracle ,显示如下:
C:\Documents and Settings\Administrator>sqlplus nokia_user/oracle@202.206.0.233/orcl

ERROR:
ORA-12541: TNS: 无监听程序
在ORA-12541: TNS: 无监听程序 错误下,无论是否在本地登录都是会提示ORA-12541: TNS: 无监听程序错误的
3)在命令行中,执行lsnrctl status
C:\Documents and Settings\Administrator>lsnrctl status

在这里可以看到监听程序参数文件的位置
4)修改监听程序参数文件
初次打开时,内容如下
# listener.ora Network Configuration File:
C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC
=
(SID_NAME = CLRExtProc)
(ORACLE_HOME =
C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS =
"EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION
=
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))
)
)
ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2
修改为:
# listener.ora Network Configuration File:
C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC
=
(SID_NAME = orcl)
(ORACLE_HOME =
C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
#(PROGRAM = extproc)
(ENVS =
"EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION
=
(ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
(ADDRESS = (PROTOCOL = TCP)(HOST =202.206.0.233)(PORT = 1521))
)
)
ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2
SID_NAME,KEY 的值修改为要访问的oracle实例的名称,HOST 修为 oracle 服务器使用的地址
5)重启listener,在命令行中依次执行 lsnrctl stop,lsnrctl start
