TRACE LINE Command
I/O tracing is faster and should eliminate most data loss. The default is BULKIO.
BULKIO cannot be used with NOCOLL.
COUNT count
specifies the number of trace records to be captured. count is an integer in the
range -1 through 32767. If count is omitted or if count equals -1, records are
accumulated until the trace is stopped.
NOCOLL
specifies that trace data from the extended segment is written to the disk file
specified in TO file-name only when one of these situations occur:
•
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 disk file and the trace is stopped automatically. 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 disk file as they become
available.
The NOCOLL option cannot be used with the BULKIO option.
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 is equal to 0. If PAGES
is omitted or pages equals zero, the default value of 64 pages is assumed.
RECSIZE size
specifies the length of the data in the trace data records. You can specify size as
an integer in the range 1024 through 4050. The length of the trace header, which is
eight bytes, is not included in size. If RECSIZE is omitted or if size equals zero,
a default value of 120 bytes is assumed.
SELECT select-spec
select-spec is one of these keywords:
ALL Traces all items
COMMON Traces common module events
MSG Traces PAM message usage
MEMORY Traces PAM memory management
CONFIG Traces PAM #CONFIG events (HP internal use only)
