Problem summary

• APAR NUMBER:  PJ40696
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  DASD
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  Catastrophic CTL-38 possible when FLSPC issued to module in
  copy.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/cp/cjio.cpy
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  None.
  
  Support Files:
  None.
  
  OTHER BINARIES TO BUILD: YES
  (C) <sys>/obj/ccsons.o
  (C) <sys>/load/CPS0.so
  
  COMMENTS:
  During file copy, when IOBs are placed on the copy delay queue,
  the write completions are handled by routine CJIOWRIT. This
  routine does not have logic for a FLSPC however, which causes a
  catastrophic CTL-38 to occur. A FLSPC is not often used by
  z/TPF and the most likely scenario that could cause this is to
  use a ZAFIL with MCHR on a record for the mod in copy. If that
  ZAFIL is sent to the copy delay queue due to either a lock not
  found or copy lock match condition, the CTL-38 may occur. A
  normal ZAFIL will not use FLSPC. A FLSPC is only used when an
  MCHR is specified instead of a normal FARF file address.
  

Problem conclusion

• SOLUTION:
  Routine CJIOWRIT has been updated to handle a FLSPC.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: NO
  None.
  
  BUILD COMMANDS AND INSTRUCTIONS: YES
  #maketpf commands for linux
