Obtaining Trace Information About a MON Object
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 parameters are being modified. pages is an integer in the
range 4 through 1024, or it is equal to 0 (zero). If PAGES is omitted or if pages
equals 0, the default value of 64 pages is assumed.
RECSIZE size
specifies the length of the data in the trace data records. You must specify the
RECSIZE option, and size must be at least 4000.
SELECT select-spec
specifies which records are collected and written to the trace file. Records are
identified by trace record type, using the descriptions that appear in PTrace
display formats. The select-spec is one or more of the following specifications:
where keyword is one or more of the following values:
TO file-spec
specifies the file to which trace information is to be written. The file might have
been previously created as an unstructured file with file code 830. An old file is
purged of data before the trace is initiated. If the file does not exist, SCF
{ keyword }
{ ( keyword [ , keyword ]... ) }
or
{ keynumber }
{ ( keynumber [ , keynumber ]... ) }
Keyword Keynumber Description
ALL -1 (or blank) specifies that all trace options are selected.
This is the default value.
The trace file can get very large very quickly. It will wrap,
if requested, or will simply stop tracing when the TO file
gets full.
