Commands
NRJECONTROL TRACEON
If you specify a disk file that does not exist, it will be
created as the destination for trace output.
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 the trace file
becomes full and more trace data is to be written, the
file is overwritten (beginning with the first record). 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. Note that LU tracing can be started for an active
workstation only. Tracing is described in Chapter 5 , “SNA NRJE
Troubleshooting,” of this manual.
