004: BIU^TRACE^ID (BIU In)
004: BIU^TRACE^ID (BIU In)
This trace record contains the inbound basic information unit (BIU) received by SNAX
level 4 from SNAX level 3.
The BIUthat is, the request/response header (RH) followed by the request/response
unit (RU)is preceded by the first six bytes of the SNAX header described in the
SNAX/XF Application Programming Manual and the SNAX/APN Application
Programming Manual.
OAF: #nnn
gives the value of the origin address field.
BIU bytes: nn
gives the number of bytes of data in this trace record, including the BIU and the six
bytes of SNAX header. This is the total length of the data, even if a small
RECSIZE value in the TRACE command caused the data in the trace record to be
truncated.
-RSP FMD FI SDI BC EC DR1I ERI
is a symbolic representation of the contents of the request/response header (RH),
using the standard IBM abbreviations. This line is interpreted as follows:
REQ, +RSP, or -RSP indicates a request, positive response, or negative response,
respectively.
FMD, NC, DFC, or SC indicates the request/response unit (RU) category.
The abbreviations that follow are as described in the IBM Systems Network
Architecture: Formats manual. If an abbreviation for a bit field is present in the
display, the corresponding bit value is 1; if the abbreviation is absent, the bit value
is 0.
The RH shown above is for a negative response in the function management data
(FMD) category. The format indicator, sense data indicator, begin chain, and end
chain bits are set to 1. The definite response 1 indicator and the exception
response indicator are also set to 1. All other bit fields are 0.
Sense: nnnnnnnn
if present, gives the hexadecimal value of the sense data in the RU. In this RU,
the sense data value is hexadecimal 08310000.
