Trace Example

The following commands will create a useful sample trace file:

1. Stop the CP6100 line:

STOP LINE $CPL1

2. Start the line:

START LINE $CPL1

3. Start the trace with the SCF TRACE command and specify SELECT ALL, PAGES

64, WRAP:

TRACE LINE $CPL1, TO <FN>, SELECT ALL, PAGES 64, WRAP

4. Wait for the CP6100 line-ready console message.

5. Stop the trace. For example:

TRACE LINE $CPL1, STOP

6. Use PTrace to format and display the trace records.

The following example of a trace allows you to examine the trace file after you recreate

the original problem:

1. Assume the line and then trace it:

ASSUME LINE $CPL1

TRACE, TO CPTRACE, PAGES 64, RECSIZE 256

2. Recreate the original error that you want to capture.

3. Stop the trace and exit:

TRACE, STOP

EXIT

4. Run PTrace:

PTRACE FROM CPTRACE

5. Check the file size:

COUNT

SELECT CLIPDI, CLIPD0, L0

OUT to file-name

RECORD ALL

EXIT

Note. Depending on the nature of the problem you are investigating, you may wish to start the

trace before starting the line.
