PI08046: ABENDALIG AFTER MIGRATION TO CTS 5.1. LOADER FAILS TO LOAD PROGRAM INTO STORAGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Sporadically, an abendALIG occurs when a program is being
  loaded into CICS. DFHAPLI1 is unable to determine the program's
  language. The program is DISabled and a dump taken.
  This can occur in one CICS region while other regions are able
  to load the same program. If the program is re-ENAbled and
  NEW copied then the program load will work.
  The dump shows, the application has issued an EXEC CICS LINK
  to program "xxxxxxx". Loader domain shows a CPE and APE for
  program  "xxxxxxxx" but its  CSECTL has "-noheda-".
  CPE_PROGRAM_STATUS has "CPE_LOADED" set with
  CPE_RECOVERY_FLAGS  set to "CPE_PROGRAM_ACQUIRED"
  & "CPE_PMARL_VALID"
  .
  Loader Domain (PROGRAM STORAGE MAP) shows the program
  load point address (the same as APE_LOAD_POINT) but the
  storage at that location is nulls (x'00'). the program appears
  not to have been loaded. Therefore, DFHAPLI1 is unable to
  determine the language of the program.

  Two tasks are running on open TCBs, both of which LINK to
  another program. The tasks go through DFHLDSVC and reach the
  LOAD routine. Here the parameter list of the LOAD SVC for the
  first program is overlaid by the parameter list for the second,
  overwriting the address of where the program is to be loaded
  so that both programs are loaded at the same address.
  The area where the first program should have been loaded
  remains set to zeros which results in an abendALIG when CICS
  attempts to determine the program language.
  

Problem conclusion

• DFHLDSVC has been changed to getmain and freemain a new piece of
  storage for the parameter list of each invocation of the LOAD
  SVC.
