  1.Abend S0C4 occurred due to incorrect parameters
    supplied to the SWAREQ service request to collect
    active LOG datasets information.
  2.High CPU utilization occurred while processing archived
    datasets data due to incorrect processing code path.
  3.Volume serial field not displayed due to incorrect
    TIOT/JFCB control block values supplied.
  

Problem conclusion

• 1. Change logic to prevent the abend and High CPU
     usage.
  2. Use correct TIOT/XTIOT entry to locate JFCB block.
