  ****************************************************************
  DFR gets and updates the control block (ADSC) in the ADSC pool
  with a X'5921' log record or a X'4087' log record that gets
  logged after a FP checkpoint.
  Then DFR analyzes log records after the selected checkpoint and
  updates the control blocks (ADSC) to the state that they were
  at the time of IMS failure.
  Whenever a X'5923' log record gets logged before a X'4080' log
  record and after a X'4001' log record, since DFR has not
  gotten the control block (ADSC) yet, it cannot update the DEDB
  area data set information.
  Then DFR issues a MSGDFR3402E REASON CODE=NOADSC message and
  ends with an ABENDU3402.
  

Problem conclusion

• The following modules have been modified.
  (x = 9, A , B and C)
  *
  DFRLFCTx - This module was changed so that DFR might bypass the
             process of X'5921', X'5922' and X'5923' log records
             whenever a FP checkpoint is not processed.
             This is because the DEDB area data set information
             will get processed later by X'4087' log records.
             . When the RSCDCKP1 bit is set to the RSCDCKPF flag
               which shows that the FP checkpoint is processed,
               DFR processes X'5921', X'5922' and X'5923' log
               records.
