oracle--本地网络配置tnsnames.ora和监听器listener.ora

文件tnsnames.ora 是给orcl客户端使用

配置本地网络服务:(客户端)
第一种使用暴力方式直接操作：
修改：C:appAdministratorproduct11.2.0dbhome_1NETWORKADMIN	nsnames.ora
				
				ORCL =        >网络服务名
				  (DESCRIPTION =
					(ADDRESS = (PROTOCOL = TCP)(HOST = 服务器ip)(PORT = 1521))
					(CONNECT_DATA =
					  (SERVER = DEDICATED)
					  (SERVICE_NAME = orcl)
					)
				  )

　　

实例

ww =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = DESKTOP-7719O7O)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

　　

　listener.ora

监听连接请求的，相当于秘书

当你请求别人的orcl时候，就会经过这个监听程序

# listener.ora Network Configuration File: D:ItSoftWareInstalledoracleproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:ItSoftWareInstalledoracleproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:ItSoftWareInstalledoracleproduct11.2.0dbhome_1inoraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = DESKTOP-7719O7O)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:ItSoftWareInstalledoracle

　如果出现如下错误，多半是windows问题，在文件中添加如下代码

第一种使用暴力方式直接操作：

					)
				  )
			第二种方式：
				使用图形界面：NCA
			配置监听器:（服务器端）
			常见问题：
				配置监听器，计算机名必须是英文的
