ORA-12154

问题
ORA-12154 : TNS:无法解析指定的连接标示符


解决方案:
1.修改%oracle_home%\NETWORK\ADMIN 下的tnsnames.ora 对应项的service_name

APPSTORE_79 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 118.123.253.79)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = appstore)
    )
  )

2.在dos下输入netca -> 本地Net服务名配置 -> 重新配置 -> 输入正确的服务名
