PH47872: REPEATING ABEND0C6 AND DFHPG0001 AFTER ABENDAICA ON X8 TCB WITH XPLINK.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After a loop ( AICA) processing on an X8 or X9 TCB ( running IBM
  transformation extender code using XPLINK) , CICS ends up with
  repeating 0C6 abends as each new task tries to use LE because
  the CICS to LE interface is no longer operational.
  
  Various symptoms can occur after the AICA recovery has been
  processed by CICS :
  
  DFHPG0001 An abend (code ---/AKEA) has occurred at
  offset X'2E70' in module DFHPGPG.
  
  DFHKE0002 applid A severe error (code X'0506') has occurred in
  module DFHKEDS
  
  DFHSO0002 applid A severe error (code X'0C48') has occurred in
  module DFHSOLS.
  
  
  This 0C6 abend is a repeating abend because the LE environment
  associated with the QR TCB is no longer operational.  Each time
  a new task tries to run and access LE it will get the same
  abend.

  After a loop ( AICA) processing on an X8 or X9 TCB ( running IBM
  transformation extender code using XPLINK), CICS ends up with
  repeating 0C6 abends as each new task tries to use LE because
  the CICS to LE interface is no longer operational.
  
  APLXREC should have restricted its clean up work for the open
  TCB of the failing program that caused APLXREC to be driven.
  However, in the reported problem, that TCB was unusable and
  it was forced to use the QR TCB incorrectly. As a consequence
  the ERTLI CICS-LE interface on QR was lost.
  

Problem conclusion

• DFHAPLX1's recovery routine has been amended to preclude the
  aforementioned scenario.  It will attempt to switch to the
  abending TCB but if that fails, it will not terminate the QR to
  LE370 interface.
