tsung 压力测 试遇到的几个问题

   
注册 用户 超过 130000 178864 设备 156584 1. 测试关于“汉字”更新数据 后台抛出 =INFO REPORT==== 2010-10-25 18:07:47 === D(<0.1906.0>:ejabberd_odbc:416) : MySQL, Send query ["UPDATE vendors SET vendorname='",[20013],"' WHERE vendorid='","37","';"]
   =INFO REPORT==== 2010-10-25 18:07:52 ===
D(<0.1906.0>:ejabberd_odbc:416) : MySQL, Send query
"rollback;"
  

解决方法: [20013] 是为调用了xmerl: xmerl_scan:string/2 返回的,只好从编码上入手,但 很不能理解 如果 下面参数 S 已经是UTF8 了在执行下面操作后 又进行了编码(为什么再次编码,此现象只出现在汉字上面)。所以只好在针对xmerl_scan:string/2的返回值进行编码,而不能写成通用的方法。 如[233,223,222] 执行下面操作后成了 [228,123,345,238,222,133](此数据是说明问题随便写的) > > + UTF8Binary = unicode:characters_to_binary(S, utf8, utf8), > > + UTF8Str = binary_to_list(UTF8Binary),

   2.单个 虚拟机 测试( <client host="client-3.langzhelabdns.com" use_controller_vm="true" maxusers="60000"/>
)
   
    解决方法:
   
   以下问题 修改ulimit -n 102400参数解决

3. ------------------------------------------------
 根据上面出现的情况 调整ulimit参数后,tsung日志出现  etimedout (ssh验证 tsung监听 )会出现此问题
参见 http://www.javaeye.com/topic/573238部分解释

=INFO REPORT==== 1-Nov-2010::13:49:47 ===
           ts_client:(3:<0.12532.0>) (Re)connect from 0.0.0.0 to testrsa.langzhelabdns.com:5280, Error: etimedout
   
    解决方
   
   法 配置ssh 信任
