Commands
TRACEON
If you do not specify the name of a trace output file, the
default file name NMTC
nnnn .PUB.SYS is used, where
nnnn is a number from 0000 through 9999. The nnnn
integer is incremented to form and find the next
available trace file name. You can always retain trace
data by using a default file name; however, considerable
disk space might be used.
If you specify an existing file, and it already is in use for
trace output, then trace output records for this activity
are interleaved with other trace output records. You
minimize the use of disk space by using an old file
appropriately; however, trace output can be
overwritten. If you specify an old file that is not already
open, the file will be overwritten with new trace data.
No warning is issued.
Size The number of logical records to be stored in the trace
file, from 0 through 32767. A logical record occupies one
sector. A trace file is created with 16 extents. One
extent is initially allocated, and additional extents are
allocated one at a time, as needed. If you omit this
parameter, a default of 1024 is used.
Description
This command is used to start intrinsic and/or LU tracing for a
workstation. Tracing is described in Chapter 5 , “SNA NRJE
Troubleshooting,” of this manual. You can specify a particular
workstation by specifying a
Wsid . Note that LU tracing can be started
for an active workstation only.
