TRACE Command
Records 8, 9, 10, and 11 will be written to the disk file. These records will be
placed in the disk file as records number 1, 2, 3, and 4, respectively. Records 5, 6,
and 7 will not be written.
If NOCOLL is not specified with WRAP when the trace is started, the trace
collector process reads the trace records from the extended data segment and
writes them to the disk file as they become available. Sometimes the tracing
process S-series writes records to the extended data segment faster than the trace
collector process can write them to disk. In this case, wrapping occurs within the
extended data segment. If this wrapping would cause the trace process to write
over trace records not yet copied to the disk file, tracing stops until those records
are written to disk.
When this situation occurs, a trace record is placed in the disk file to indicate the
number of trace records that were missed while tracing was stopped. The record
contains the date, a timestamp, and a message indicating the number of records
missed. For example:
10/19/92 14:40:27.995571 >000.114976 #302 Frames Missed
Number of frames missed: 26
SELECT Options
The choice of select-spec options for the SELECT attribute depends on the device
type.
The following subsections list the select-spec options for SNAX/XF and SNAX/APN
LINE objects and the SUBSYS object. In the option descriptions, each keyword is
followed by its corresponding number in parentheses. The options for SNAX/XF and
SNAX/APN lines are listed according to the device subtype to which they apply. If no
select-spec options are explicitly selected, all are traced: that is, the default value is
ALL.
