SNA NRJE Troubleshooting
Using NMDUMP for SNA NRJE
• Option 3 specifies whether character mode is to be on or off. If
character mode is on, each unformatted hexadecimal or octal output
line is followed by a line containing the corresponding printable
characters in the character code specified by option 4. Nonprintable
characters are represented as periods.
• Option 4 specifies the character code the data is to be printed in:
ASCII or EBCDIC.
• Option 5 allows the user to disable or enable unformatted data
dumps (that is, lines with hexadecimal or octal numbers only [no
text]). If the data dumps are enabled, the data of the formatted
sections is also represented as unformatted raw data (as it appears
in the input record). If the dumps are disabled, only formatted
sections appear in the output (except for the Request Unit sections
in some SNA Transport records, which are always printed).
In Figure 5-1, the values shown for the options are the default values.
To change the value of an option, type the option number and press
[RETURN]. If all the values are as you want them, you can exit the menu
by pressing
[RETURN] without specifying an option number.
SNA NRJE Output Formats
For SNA NRJE, NMDUMP formats tracing records and logging records.
The format for each type of record is described below.
Tracing Records
Tracing records are identified by a type and a subtype. In a formatted
trace record, the type and subtype numbers are shown in parentheses,
on the first line of information after the “Info section.”
The data in the “Info section” is displayed in either hexadecimal
(preceded by a pound sign) or octal (preceded by a percent sign),
according to what was specified for option 1 on the NMDUMP
Formatting Options menu.
LU Trace Records @LU trace records are type 0, and are formatted
according to five subtypes:
• Called by CI or intrinsics:
— Subtype 0: workstation number
— Subtype 1: wsid and number
• Called from an LU process:
— Subtype 4: LU number and workstation number
— Subtype 6: LUID and number, and workstation number
— Subtype 7: LUID and number, and wsid and number
