  *                      because the CPE_APE_CHAIN_SIZE value    *
  *                      does not reflect the number of APEs on  *

  ****************************************************************
  The customer's environment had many thousands of program
  definitions, and a load library staging with various libraries.
  Programs were compiled into one library, and could then be moved
  into another library while CICS was running. CICS SET PROGRAM
  PHASEIN commands could occasionally fail if a library did
  not happen to be available at the time of the command. The
  PHASEIN would return IOERR to the SPI.
  
  In the failing case, a program was in use when its library
  resource was discarded from CICS and then a PHASEIN of the
  program attempted. This failed with IOERR as the library was
  not defined to CICS at that time.
  
  A subsequent LOAD of the program worked, but as part of the
  load processing DFHLDLD1's PHYSICAL_LOAD routine added the APE
  that had been created during the earlier failed phasein attempt
  onto the chain of APEs from the CPE and incremented the count.
  This meant the value in CPE_APE_CHAIN_SIZE no longer matched
  the number of APEs chained from the CPE. This later led to a
  subsequent failure DFHPG0002 and DFHAP0001 being reported.
  

Problem conclusion

• DFHLDLD1 has been changed to ensure that the LDAD entry for
  the APE of the program being phased-in is removed from the
  directory if the program locate fails. This prevents the
  subsequent LOAD command from locating the LDAD entry and so
  rechaining the same APE to the CPE.
