Oracle 11g ORA-12514:TNS:监听程序当前无法识别连接描述符中请求的服务

创建数据库test

1.打开Oracle net manager

2.服务命名:test

tcpip 主机：127.0.0.1 端口：1521

3.监听程序

选择 监听位置

网络地址：localhost

端口：1521

选择 数据库服务

全局数据库名 SID： test

4.停止监听服务 启动监听服务

# listener.ora Network Configuration File: E:appAdministratorproduct11.1.0db_1NETWORKADMINlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = test)
      (SID_NAME = test)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = NBS)
      (SID_NAME = NBS)
    )
  )

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
  )

2个数据库服务一个test，一个NBS，公用一个监听

# tnsnames.ora Network Configuration File: E:appAdministratorproduct11.1.0db_1NETWORKADMIN	nsnames.ora
# Generated by Oracle configuration tools.

test=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test)
    )
  )

NBS =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = NBS)
    )
  )

客户端无法访问服务器 Oracle 出现12541错误

C:WindowsSystem32driversetc

修改hosts

10.50.180.123 andyzc

服务器ip 主机名

然后在listener.ora将localhost改为andyzc

cmd-》tsnping andyzc

出现ok就可以用客户端连接到服务器了
