晴天钟服务器负载过高 | Heavy traffic at the 7Timer server

晴天钟程序API新添如下地址： http://www.7timer.com/v4/bin/api.pl?lon=&lat=&product= &output= 仍提供XML及JSON两种格式的封装，格式不变。欢迎各位程序作者进行测试。旧的API仍将保留一段时间，建议各位在方便时迁移至新API。 The machine-readable API has been upgraded and forecast data can be retrieved at such address: http://www.7timer.com/v4/bin/api.pl?lon=&lat=&product= &output= The format is unaltered. Program authors are encouraged to test and migrate to this new API. We hope all program retrieval will be performed through the new API as it greatly reduces (hopefully) the…

　　从10月26日开始，服务器再次出现访问过载的情况，在北京时间29日早上开始变得难以访问。为了缓解这一问题，CIVIL服务不得不被暂时停止。数据更新应该能在今天晚些时候恢复，但访问过载问题可能将花较长时间解决。 　　我注意到有同好提出有关天之文服务器稳定问题的疑问，在这里有必要澄清。晴天钟在迁移到天之文服务器之后，可利用的硬件资源大大增加，许多原先设想的功能得以实现，访问量在两年间增加了150倍，这和天之文的负责人，尤其是上海天文台的林清博士和汤海明老师的大力支持是分不开的。但是，任何服务器都是有承载极限的，目前的高流量已经对服务器造成了相当大的压力，我们在尽力争取资源解决这一问题。总之，请大家不要对服务器产生不必要的担心。 The server has again experienced a very high traffic since Oct 26, and has become partially unreachable in the evening of Oct 28 (EDT). We have to temporary disable CIVIL service (both on-site and APIs) to keep the server operational. The data update is expected to resume later today, but the problem may…

　　经过努力，服务器目前已经能够应对较高的访问量，数据更新已经从10月10日开始恢复正常。这两天服务器可能偶尔会出现反应稍慢的情况，这是正常的。为了防止类似的问题再次出现，程序API将同时处理的请求数由128个调整为64个，超出这一数字的请求将会返回ERR50013错误，请程序开发者参考更新后的文档。 After code revision, the server can handle moderately heavy traffic now, regular data updates have been resumed since Oct 10. The server may remain slightly slow for given times for a few more days. In respond to this issue, the simultaneous request limit of program API has been reduced from 128 to 64, additional…

　　在上海天文台汤海明版主及服务器维护人员以及IBM工程师的努力下，晴天钟网络服务于今晚18时左右恢复，预计首批更新将在22日1点左右放出。 Under the efforts from Mr. Tang Haiming and the maintainance crew at Shanghai Astronomical Observatory as well as from the IBM rescue engineers, the web service of 7Timer server was resumed around 10h UT today. The first release of data is expected to be done around 17h UT.

　　新晴天钟再次进行了若干修正，详列如下： 重写了XML和JSON API； 民用及民用简化版加入了“零星阵雨”和“局地阵雨”两种天气状况，民用、民用简化版及两周展望进行了一些发报机制修正； 预报页面加入地址解析功能，预报图表下方同时显示图例以及相关信息。 　　若无重大改动，晴天钟将在7月31日前正式切换到新平台上使用，旧平台网站界面将不再对外提供服务，但预报界面（含API）将至少运转到今年底。 A few modifications are made on the new 7Timer platform. They are: Re-write the XML/JSON API output. "Occasional showers" and "isolated showers" are added to CIVIL and CIVIL Light forecasts, plus some adjustment of the forecast scheme. Adding current site geocoding of the forecast pages, as well as in-page…
