TRACE SUBNET Command for TCPMAN
BULKIO / NOBULKIO
specifies whether TRACE should use bulk I/O for tracing. BULKIO, the default
parameter, 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.
BULKIO and NOBULKIO are optional parameters.
SELECT
selects the operations to be traced.
For the SUBNET object, you can specify the following for select-spec:
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.
NOCOLL
indicates that the trace collector process should not be initiated. WRAP and
NOCOLL cannot be specified at the same time.
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.
ALL All records
