Error description

• IMS DEDB Fast Recovery enhancement to support IMS V7 APAR
  PK06393 (PTF is UK04737), IMS V8 APAR PQ96856 (PTF is UK04738)
  and IMS V9 APAR PK01803 (PTF is UK04739).
  
  Original issue leading up to this:
   In a Fast Path data share environment, a shortage in IRLM MCSA
   or insufficient IRLM lock structure size during a HSSP or HSRE
   run will prevent a successful notify for DMAC sync across the
   sysplex. This leads to an inability to /DBR the area on the IMS
   that owns the HS type utility if a /DBR was done on the
   non-utility owning IMS first.

  -PK16378 for IMS DEDB Fast Recovery
  Under the situation, /DBR command does not work on the 'HS'
  type utility home IMS if the IMS's DMAC has DMACUTIL,DMACPBPU
  though the utility is no longer active. DFR should clear
  these fields when it updates the DEDB AREA 2nd CI.
  

Problem conclusion

Temporary fix

Comments

• The following modules have been modified.
  (x = 7, 8 and 9)
  *
  DFRNFCLx - This module does not write DMACPBPU and DMACPBCT to
             the DEDB 2nd CI for non-block level shared AREA when
             DMACURNM has 'HS'.
  DFRNFSTx - This module does not write DMACPBPU and DMACPBCT to
             the DEDB 2nd CI for block level shared AREA when
             DMACURNM has 'HS'.
