[田中 義一 <yt...@ni...>]

Hi,

Thank you for your quick reply.
You have thought that problems occurs when staging.
But the too many file problems ocuurs even in  the following job without data-staging

<?xml version="1.0" encoding="UTF-8"?>
<JobDefinition xmlns="http://schemas.ggf.org/jsdl/2005/11/jsdl">
  <JobDescription>
    <Application>
      <POSIXApplication xmlns="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix">
        <Executable>/bin/hostname</Executable>
        <Output>host.txt</Output>
        <WorkingDirectory>./tmp</WorkingDirectory>
      </POSIXApplication>
    </Application>
  </JobDescription>
  <MyProxy xmlns="urn:gridsam:myproxy">
     <ProxyServer>*******</ProxyServer>
     <ProxyServerUserName>******</ProxyServerUserName>
     <ProxyServerPassPhrase>******</ProxyServerPassPhrase>
  </MyProxy>

</JobDefinition>
