TRACE MON Command for TCP6MAN
COUNT count
specifies the number of trace records to be captured. count is an integer in the
range -1 through 32767. If this option is omitted or if count equals -1, records are
accumulated until you use the STOP option or until the file-spec 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, not when its attributes are being modified. pages is an integer in the
range 4 through 64, or it is equal to 0. If you omit this option or specify 0, the
default value of 64 is applied to the trace.
RECSIZE
specifies the length, in bytes, of the data in the trace data records. size is an
integer in the range 300 through 4050. The length of the trace header, which is 8
bytes, is not included in size. If you omit this option or specify 0, an error occurs.
NOBULKIO
specifies that TRACE should not use bulk I/O for tracing. (BULKIO, not supported
in NonStop TCP/IPv6, specifies that the TRACE collector use Bulk I/O to write data
to the disk file, thus reducing the number of missing frame errors reported by
PTRACE.)
WRAP
specifies that when the trace disk file end-of-file (EOF) is reached, trace data
wraps around to the beginning of the file and overwrites any data that is there.
Example
->TRACE MON $ZZTCP.#ZPTM0, TO TRACE1, RECSIZE 300, NOBULKIO
->TRACE,STOP
->PTRACE FROM TRACE1
