{ 
    SysDataImport sysDataImport; 
    boolean       sysTraceActive = xSession::getSysTraceActive(); 
 
    sysDataImport = SysDataImport::newTmpFilename(''); 
    sysDataImport.addTmpExpImpTable( 
        tablenum(SysTraceTableSQL), 
        false); 
  
    sysDataImport.addTmpExpImpTable(

        tablenum(SysTraceTableSQLTabRef), 
        false); 
  
    xSession::setSysTraceActive(FALSE);
