TRACE PROCESS Command
specified. Bulk 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-spec 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 disk file, and the trace is automatically stopped. 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.
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. size is 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, the default value 
of 120 bytes is assumed.
SELECT select-spec
select-spec is one of:
{ keyword }
{ ( keyword [ , keyword ] ... ) }
{ number }
{ ( number [ , number ] ... ) }
