004: BIU^TRACE^ID (BIU Out)
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.
REQ FMD BC EC DR1I BBI
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 request in the function management data (FMD)
category. The begin chain and end chain bits are set to 1. The definite response 1
indicator and the begin bracket 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
example, which is a request, no sense data is present.)
request or RU: nnnnnn
if present, gives additional information from the beginning of the RU. If the BIU
contains an SNA request (or a response to an SNA request) such as ACTPU,
ACTLU, or BIND, the abbreviation for the request appears here. If the BIU
contains invalid or unrecognized data, the display shows RU: followed by the first
six bytes of the RU in hexadecimal. If this is a response that includes sense data,
or if the BIU contains FMD data and the FI bit is not set, as in this example, this
field does not appear.
0000 0000 0001 0380 ...
is the first six bytes of the SNAX header followed by the contents of the BIU (RH
and RU).
0000 0000 0001
is the first six bytes of the SNAX header.
