  When using the TAPECHK option, DRF is expected to recognize the
  number of available tape devices as specified by the user with
  the READNUM option.  DRF is expected to wait for the next
  available tape device before attempting to mount another tape in
  parallel to other running processes.  However, there are cases
  where image copy tapes are allocated to a device before log and
  change accumulation tapes had a chance to be unallocated from
  their devices.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  Allocation logic for log and change accumulation data sets is
  change to keep a count of the number of tape devices allocated
  for log and CA read.  This count will help prevent the
  subordinate address spaces from exceeding the number of
  available tape devices supplied on READNUM during image copy
  allocation.
