TRACE Command
SUBSYS subsystem-name
is a valid subsystem name indicating the desired IPXMGR process (always
$ZMGR).
STOP
ends the trace operation. A TRACE command must include either the STOP or the
TO option.
COUNT count
specifies the number of trace records to be captured. count is an integer in the
range -1 through 32767. If you omit this option or if count equals -1, records
accumulate until the trace is stopped.
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. You can specify pages only when a trace is being
initiated, not when its parameters are being modified. pages is an integer in the
range 4 through 1024 or equal to 0. If you omit this option or specify 0, trace takes
the default value 64.
RECSIZE size
specifies the length of the data in the trace data records. size is an integer in the
range 16 through 4050 or equal to 0. The length of the trace header is not included
in size. If you omit this option or specify 0, tracing takes the default value of 120
bytes. In this case, the data may be truncated. If data is truncated, set a higher value
to ensure that you can see the entire trace record. The recommended trace record
size for an IPXPROTO process is 1024.
SELECT select-spec
selects the operations to be traced. The default is ALL. For the PROCESS object,
the select-spec words are listed in Table 3-5 on page 3-49.
TO file-spec
specifies the name of the file into which the results of the trace operation are to be
placed. This option is required if you don’t STOP.
WRAP
specifies that when the trace disk file end-of-file (EOF) is reached, trace data wraps
to the beginning of the file and overwrites data.
