  ****************************************************************
  Before enhancement, HPFPU Hash Check support for IMS Database
  Recovery Facility always opens/closes temporary FABAMSG,
  FABARPRT and FABASNAP datasets for each area, and those
  datasets are always allocated on DASD.
  With this APAR, HPFPU Hash Check support can optionally obtain
  the DCB addresses of temporary FABAMSG, FABARPRT and FABASNAP
  from IMS Database Recovery Facility, instead of opening/closing
  those datasets by itself, and can write the outputs to SYSOUT
  directly.
  

Problem conclusion

Temporary fix

Comments

• HPFPU Hash Check support has been modified to obtain the DCB
  addresses of output datasets from IMS Database Recovery
  Facility.
