PH42520: IF YOU HAVE MORE THAN 90 DATA SETS IN THE DFHRPL CONCATENATION, LOADER FORMATTING WILL FAIL.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This customer had 116 data sets in the DFHRPL concatenation,
  
  and when using IPCS with LD=3, saw the following errors:
      ** DFHPD0128 Invalid data length 1474 specified for
  
           address 26516000.
  
      ** DFHPD0103 PLIBE_RP address 26516000 is invalid.
  
  This happens if the DFHRPL has more than 90 data sets.
  
  IPCS has a maximum buffer size (IPCS_MAX_BUFFER_SIZE)
  
  of 4096 and with 90+ files this RPL concatenation is greater
  
  than 4096 and so gets the length error.
  
  
  Additional symptoms: KIXREVCM
  

Local fix

• Reduce the number of data sets in the DFHRPL list so
  there is less than 90 files.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Using IPCS to format the LD domain with *
  *                      a large number of DFHRPL data sets      *
  *                      results in DFHPD0128 and DFHPD0103.     *
  ****************************************************************
  IPCS has a buffer limit of 4096. A DFHRPL concatenation
  containing more than 90 data sets exceeds this size and will
  result in messages DFHPD0128 and DFHPD0103 being issued.
  

Problem conclusion

• DFHLDDUF has been changed to check for the number of DFHRPL
  data sets and if the number exceeds 90, the formatting of the
  RPL will be truncated to 90. A message indicating the RPL has
  been truncated is written in the IPCS output.
