title: Datastage 8.1 Change temporary directories for SORT operations
body: <p>Someone knows how to change temporary directory location from Datastage configuration? My problems is while a SORT operation is performed, unix directories /var and /tmp are filled over its limit and whole process is failing.</p>
  
  <p>I tried change <strong>dsenv</strong> and <strong>uvconfig</strong> under DSEngine directory, adding variables <strong>TMP, TMPDIR and TEMPDIR</strong> pointing to other directories then restart DS services,but is not working /tmp and /var still filled to 100% showing this error:</p>
  
  <blockquote>
    <p>Sort,0: sort: 0653-657 A write error occurred while sorting.</p>
    
    <p>Sort,0: Failure during execution of operator logic.</p>
    
    <p>Sort,0: Fatal Error: Null arg.</p>
