TRACE Command
( s-name [, s-name]...)
specifies a list of sessions to be traced.
If you are starting a trace and do not specify SESSIONSELECT, all sessions are
traced. If you are modifying an existing trace and do not specify
SESSIONSELECT, the list of selected sessions does not change.
TO file-name
specifies that a new trace is to be started and names the HP disk file to receive the
trace information.
If TO is not specified, the existing trace is either stopped (if STOP is specified) or
modified as specified in the trace-option list.
WRAP
specifies that trace records written to the disk file named in TO file-name are to
be wrapped when the file becomes full. This option can be specified only when the
trace is being initiated—that is, when the TO option is specified.
If WRAP is not specified, tracing will stop when the disk file becomes full. Note that
the WRAP option applies only to the disk file; within the extended data segment,
trace records are always wrapped when the extended data segment becomes full.
The operation of wrapping when WRAP is specified depends on whether NOCOLL
is specified.
If NOCOLL is specified along with WRAP when the trace is started (as shown in
the following diagram), then when the trace is stopped and a wrap has occurred
within the extended data segment, the trace data from the beginning of the
extended data segment to the last record placed in the segment is written to the
disk file.
Note. SESSIONSELECT tracing is limited to 10 session selections in a single TRACE
command. You can, however, select additional sessions by entering multiple TRACE
commands modifying the same trace.
