TWAONCN (X'10')
Normal CLSDST (no reset allowed)
TWAOSCN (X'08')
Normal CLSDST (reset allowed)
TWAONEGR (X'04')
Send negative response
TWAOOS (X'02')
Keep node out of service
TWAOCN (X'01')
CLSDST node. Do not set this flag when processing error codeX'49'
(TCZCLSIN).
TWAONINT forces TWAOCN.
TWAONEGR forces TWAOAR and TWAOAT.
TWAOOS forces TWAOCN.
TWAOCN forces TWAOAR, TWAOAS, and TWAOAT.
TWAOOS indicates that no further processing is to be done for this node. The
node is logically out of service.
For an LU6.1 intersystem communication session, TWAOOS or TWAONINT
causes the system entry to be put out of service if, as a result of the specified
action, there are no allocatable sessions left. (A session can also be put out of
service because of either an unknown modename being passed to VTAM
during an attempt to bind an APPC session, or an invalid logmode name for a
VTAM 3270-type terminal. However, the CICS default action resulting from this
condition cannot be overridden in the NEP.)
If TWAOCN is set, the task is abnormally terminated and communication with
the node is lost. Note that the NEP cannot reset this flag.
TWAOSCN provides the same function as TWAONCN, but the NEP can reset it
if the session is not to be closed.
If DFHZNAC is scheduled because of the receipt of an exception response, the
sense information in the TCTTE is available to DFHZNAC and DFHZNEP to
determine any necessary actions.
If DFHZNAC is scheduled because of loss of the connection between CICS and
a logical unit, DFHZNAC abnormally terminates any transaction in progress at
the time of the failure. DFHZNEP and transaction-class error routine analysis
and processing are permitted, but you should not attempt to retry the message.
However, if the application program handles the ‘TERMERR’ condition, the
transaction is not abended. Control is returned to the program. In this
circumstance, no further use can be made of the failed session.
Additional information for the NEP (TWAADINF)
Fields TWANPFW, TWANLD, and TWANLDL can be reset by the NEP. For
information about the use of TWANPFW, see the supplied sample node error
program, and “Optional error processor for interactive logical units” on page 499.

You can use the logging facility available in DFHZNAC to aid in retrieving
information. You specify the address of the data that you want to examine in field
