PI08177: DFHWB0001 REPORTS ABEND0C4 IN DFHWBSR AT OFFSET X'9F66' 16/11/28 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible in next release.

Error description

• DFHWBSR (at base level) is failing in routine
  SEND_STATIC_RESPONSE while trying to work with a file within
  the HFS directory structure. The associated URIMAP contains an
  HFS directory path (HFSFILE attribute) which only points to the
  directories within the path and not to the specific file.
  .
  The failure is within wbsr_process_hfs_directory. The failing
  instruction is an ICM (BF23 3BAE). The problem is due to
  register 3 being zeros (register 3 should be a base register
  used by DFHWBSR). Register 3 is destroyed when used in the MVCL
  instruction located at offset x'9F38' where the port address is
  being moved.
  The MVCL instruction makes use of register pairs 2,3 and 6,7.
  Thus the move counts down register 3 to zero.
  .

Local fix

• Code a hardcoded URIMAP to include a path pointing to the
  specific file used for the static response via the HFSFILE
  atribute.

  An 0C4 occurred within DFHWBSR when attempting to send static
  web content through a URIMAP.  The URIMAP was defined with a
  directory as the static content. If the incoming URI does not
  end in a / CICS attempts to redirect the client to the correct
  URI location ending in a /.  During the construction of the
  redirect URI an 0C4 occurs.
