TRACE LINE Command
COUNT count
specifies the number of trace records that you want to capture. count is an integer
in the range -1 through 32767. If you omit COUNT or if count equals -1, records
accumulate until you stop the trace or until the end-of-file is reached if you do not
select the WRAP option (described below).
NOCOLL
optionally specifies that trace data from the extended segment is written to the file
specified in TO file-name only when one of the following occurs:
The trace is stopped.
The number of trace records written to the extended data segment is equal to
the COUNT specified in the TRACE command that started the trace. When the
trace facility detects this condition, the trace records from the extended data
segment are written to the file and the trace is automatically stopped. As a
result, a separate TRACE command does not need to be issued to stop the
trace.
If NOCOLL is not specified, a trace collector process reads the trace records from
the extended data segment and writes them to the file as they become available.
PAGES pages
designates how much memory space, in units of 2048-byte pages, you want to
allocate in the extended data segment used for tracing. pages is either 0 or an
integer in the range 4 through 1024. If you omit PAGES or if pages equals 0, SCF
assumes the default value of 64 pages.
RECSIZE sizes
specifies the length of the data in the trace data records. sizes is either 0 or an
integer in the range 16 through 4050. The length of the trace header, which is 8
bytes, is not included in size. If RECSIZE is omitted or if size equals 0, SCF
assumes the default value of 120 bytes.
The maximum CLIP trace record size (RECSIZE) is 21. If the record exceeds the
record size, 10 bytes from the start of the message and 11 bytes from the end of
the message are included.
SELECT select-spec
defines the data items to be traced.
select-spec is one of the following specifications:
{ keywords }
{ (keywords [ , keywords ]...) }
{ number }
{ (number [ , number ]... ) }
