PK42773: DFHME0006 'MVS GETMAIN FAILED' TRYING TO ISSUE MESSAGE DFHFC0955.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DFHME0006 is issued trying to process message DFHFC0955 from
  DFHFCRO. The problem is that fcro_dslen has not been initialised
  and thus the length passed to DFHMEME by DFHFCRO contains blanks
  for the length, thus causing the DFHME0006 'MVS getmain failure'
  message to be issued.

  In the reported problem, CICS issued message DFHME0006
  attempting to GETMAIN an inordinate amount of storage required
  for an insert in message DFHFC0955. The insert length field for
  DFHFC0955 was uninitialised and the message domain happened to
  use residual data of x'40404040' hence the DFHME0006. Had the
  residual data contained zero (probably more commonplace), then
  DFHFC0955 would have been issued without the DFHME0006 but also,
  the insert whose purpose is to identify a VSAM dataset
  referenced in earlier messages, would have been missing.
  
  Had the residual data contained zero (probably more
  commonplace), then DFHFC0955 would have been issued without the
  identifying VSAM dataset name.  Likewise, residual data equating
  to a large number may cause a WTO buffer overflow and residual
  data equating to a negative value would result in no DFHFC0955
  being issued at all.

Problem conclusion

• DFHFCRO has been modified by initialising fcro_dslen.
