Line trace summary reports

z/OS Communications Server: ACF/TAP Trace Analysis Handbook
GC27-3645-00

The selection parameter is LSPRT for NCP V4R3.1 and later.

Requirement: A system sort program is required to produce this report.

This topic includes line trace summary reports. See the following figures:

Table 1 describes the column headers and the trace data contained in this report type. To locate this information about the sample reports, reference the numbers (n) listed in this table to the corresponding numbers (n) shown in the sample reports.

Table 1. Line trace summary report
Reference number (n) Report column headers and the trace data
1 The page heading contains the report name, report parameter, and the date the report was printed or displayed.
2
LINE
The element address of the line being traced.
3
CORR
The NCP-assigned correlator number that puts line trace events in chronological order.
Note: When receive ready suppression (RRSUP=YES) or timeout suppression (TOSUP) is on, the correlator numbers of those Receive Ready/Receive-Not-Ready frames and timeout frames are not seen in the line trace summary report.
4
RECORD ELEMENT
This is a cross-reference to record or message numbers in other ACF/TAP reports.
5
ELEMENT NUMBER
The ACF/TAP-assigned sequence number of the last complete element shown on this line.
6
Address and control information:
ADDR
Address byte
CMND
Command
CNTL
Control bytes
IDENT
Element identifier
NR
Number received
NS
Number sent
PF
Poll/Final
TCC
Transmission correlation count
TIME
Timestamp
Note: In some cases, the address information in this report does not agree with the address displayed on the line trace device or in the generation definition. The scanner might change the address because of the way it passes data to NCP. However, the scanner interface trace displays the correct address.
7
HEX
The trace data for the line trace element, in hexadecimal.
8
DATA TRANSLATION/EXCEPTION STATUS
This is the EBCDIC equivalent of the hexadecimal trace data.

For more information about gathering data for the CSP data trace, ESS line data trace, frame-relay physical data trace, frame-relay physical with BNN HPR data trace, and X.25 data trace, see Gathering host-collected trace data.
