Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Items being addressed:
  1. The incorrect data set name of the secondary SLDS is set to
     'OLDS/SLDS LIST.'
  2. ABENDU1058E with MSGDFR1058E RSN=02 occurs when the scope of
     the online change of the target IMS system, that is an XRF
     complex, is global.

  The following problems are fixed by this APAR:
  
  1. The incorrect data set name of the secondary SLDS is set to
     'OLDS/SLDS LIST.'
  
     If you reply the ddnames of the primary SLDS and the
     secondary SLDS, that contains the checkpoint log, to
     MSGDFR3110A when DBRC=N is specified, DFR set an incorrect
     data set name of the secondary SLDS to 'OLDS/SLDS LIST.'
  
  2. ABENDU1058E with MSGDFR1058E RSN=02 occurs when the scope of
     the online change of the target IMS system, that is an XRF
     complex, is global.
  
     Since the timing to which DFR gets IMSID from an IMS log is
     late when the target IMS system is XRF complex, DFR cannot
     analyze the record of the OLCSTAT data set correctly.
     And DFR ends with an abend code U1058.
  
  3. ABENDU3999 occurs in DFRLDB2x module, or invalid information
     of UOR is set to 'RESYNC CONTROL STATEMENT LIST.'
  
     Since DFR processes all entries included in X'4030' log as
     the same RRE-TYPE as the first entry, DFR cannot recognize an
     IN-DOUBT transaction correctly.
  

Problem conclusion

• The following modules and macros have been modified.
  (x = 8 and 9)
  
  DFRGAL1x - This module was changed so that the data set name of
             the secondary SLDS might be surely saved at the time
             of DBRC=N.
  DFRIGOCx - This module was changed so that timing which checks
             IMSID of the record of an OLCSTAT data set might be
             performed, after IMSID was got from an IMS log.
  DFRLUORx - This module was changed so that RRE-TYPE of all
             entries included in X'4030' log might be judged
             correctly.
  DFRRSCx  - New RSCDOLLN field was added for the length of the
             OLCSTAT data set record.
  DFROLC8  - The RSCDOLLN field name was changed into RSCDOCSL.
