  Abend AW2A occurs when transaction CW2A is attached as a
  non-Web transaction. However, the routine that issues this
  abend also attempts to issue a CICS message, but does so with
  an invalid parameter list so that message DFHME0111 is issued
  instead, and a system dump with CODE=ME0111 is also taken.
  Abend AW2B occurs when the Transaction Work Area for
  transaction CW2A is not large enough.
  Neither AW2A nor AW2C appears in Messages and Codes or
  in the CMAC transaction.

Problem conclusion

• The code that attempts to issue message DFHW20100 in
  DFHW2A has been removed.
  Descriptions of abend codes AW2A and AW2B have been
  added to Messages and Codes, and to the CMAC transaction.
  
  The CICS Transaction Server for z/OS Version 4 Release 1
  Messages and Codes manual, GC34-7035-00, has been altered
  to add descriptions for abends AW2A and AW2B as follows:
  
  AW2A
  
  EXPLANATION:  The DFHW2A Web2.0 alias program was executed
  in a transaction that was not attached by CICS Web Support.
  This is usually caused by attempting to issue the CW2A
  transaction directly from a terminal.  This is not
  supported.
  
  SYSTEM ACTION:  The task is abnormally terminated with a
  CICS transaction dump.
  
  USER RESPONSE:  Do not attempt to execute the CW2A
  transaction from a terminal.
  
  MODULE:  DFHW2W2
  
  ****************************************************************
  
  AW2B
  
  EXPLANATION:  The CICS-supplied Atom service routines use
  the Transaction Work Area to contains responses to be
  returned to the Atom feed manager.  The service routine has
  determined that the Transaction Work Area is too small to
  contain the required responses.
  
  SYSTEM ACTION:  The task is abnormally terminated with a
  CICS transaction dump.
  
  USER RESPONSE:  Copy the definition of transaction CW2A
  from the DFHWEB2 group.  Increase the value of TWASIZE in
  the copied definition.  The value should be at least five
  times the size of the maximum selector value that will be
  returned by the service routine.  When the resource being
  delivered is a CICS file, the selector length is determined
  by the key length of the file and the selector format
  specified on the cics:selector format attribute in the
  ATOMSERVICE configuration file.  If the format attribute is
  "hexadecimal", the selector length is twice the key length,
  otherwise it is equal to the key length.
  
  After modifying TWASIZE, install the new definition for
  CW2A.
