Error description

  • Rational Developer for System z trace causes performance problem
    due to excessive trace output for the trace points in
    findBadHex()
    
    Tracing is activated by specifying debug_level=2 in
    rsecomm.properties or the command /f rsed,appl=rcl on
    
    Analyze of the logs from test1 and showed that the performance
    delay is caused by a very high increase of entries in the
    ffsget.log. The following 2 log output lines are repeated many
    times depending on the source data. Most of these two
    tracepoints are in one or more short timeframes.
