  DFHRML1D is driven to reconstruct RMLKs as part of system
  recovery processing. It also deletes links that can be
  forgotten. Typically this will be after a paired set of RMLK
  log records have been retrieved from the backwards scan
  of the log. When the first RMLK record (the last to be logged
  for a given use of an RMC used by a particular unit of work)
  is retrieved, a new RMLK is created and added to the global
  chain of links, as well as the linkset of the owning UOW.
  When the second RMLK record (the first of the pair to be
  logged) is encountered further on the backwards scan, the
  RMLK is deleted if it can now be forgotten. Part of this
  process involves removing it from the global chain and also
  from the linkset.
    In some circumstances, an RMLK can be logged for the first
  use of an instance of an RMC for an RMUW, yet that RMLK also
  be deemed forgettable at the same time. If such a record is
  encountered on a restart, it causes DFHRML1D to rebuild the
  RMLK for it, add it to the global chain, but avoid adding it
  to the linkset (as it is forgettable). However, when the code
  deletes the RMLK from the global chain as part of the forget
  processing, it also tries to remove it from the linkset. This
  results in the DFHRM0001 abend 0C4/AKEA.

Problem conclusion

• DFHRML1D has been changed to add RMLKs to their linksets
  regardless of whether or not they are forgettable and so
  able to be deleted later in their processing.
