TRACE LINE Command
COUNT count
specifies the number of trace records to be captured. count is an integer in the range
-1 through 32767. If you omit COUNT or if count equals -1, records accumulate
until the line trace is stopped. The trace can be stopped by the user, or if WRAP is
not specified, when the file is full.
NOCOLL
indicates that the trace collector process should not be initiated.
PAGES pages
designates how much space, in units of pages, is allocated in the extended data
segment used for tracing. PAGES can be specified only when a trace is being
initiated. pages is an integer in the range 4 through 1024 or equal to 0 (zero). If
you omit PAGES or if pages equals 0, SCF assumes the default value of 64 pages.
You can also specify a number in the range 4 through 1024; whatever number you
specify will be used.
RECSIZE size
specifies the record length in bytes. RSIZE (RECSIZE) specifies the maximum
amount of information transferred between the Envoy line-handler process and the
DLC (running in the SWAN concentrator) in one operation. The attribute is required
for the WAN Manager program; however, the RSIZE value does not have any actual
function in configuring an Envoy line handler process.
The minimum value for RECSIZE (RSIZE) is 512 and the maximum is 4095 for all
protocols.
SELECT select-spec
select-spec is one of the following specifications:
{ keyword }
{ ( keyword [ , keyword ]...) }
{ number }
{ ( number [ , number ]... ) }
keyword
is subsystem-specific. See Table 5-6 for a list of the keywords that can be used
with Envoy.
number
is the numeric value that a keyword represents.
TO file-spec
specifies the file to which SCF writes trace information. An old file is purged of data
before the trace is initiated. If the file does not exist, SCF creates one with an extent
based on the value of the PAGES parameter (see PAGES, above).
