Oracle—TNS12154

一、查看配置

oracle-db1-network-admin-listener.ora和tnsnames.ora

1.tnsnames.ora

数据库名称 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 主机名称，例如，PC02320U.com.cn)(PORT = 1521（端口名）))
    (CONNECT_DATA =
      (SERVER = SHARED)
      (SERVICE_NAME = 数据库全局域名)
    )
  )

2.listener.ora

(SID_DESC =
       (GLOBAL_DBNAME = 数据库名称)
       (ORACLE_HOME = D:\oracle\product\10.1.0\db_1（文件位置）)
       (SID_NAME =数据库名称 )
      )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST =本机域名)(PORT = 端口号))
      )
    )
  )

二、重启服务

计算机管理-服务与应用程序-服务-重启对应的服务

三、重启TNS

和上述方法类似
