NetSpool internal wrap trace

The NetSpool internal trace contains hexadecimal entries for most module entries and exits. Trace data is maintained in internal storage and wraps when the trace storage area is full. Because the internal trace wraps, it reflects only the most recent history of NetSpool processing.

You can request internal tracing of NetSpool's program control and the printer LUs processed by NetSpool. When you request a full trace, you automatically receive an internal trace. For each printer LU that is externally traced, a corresponding internal trace is provided.

The internal trace is maintained in internal storage and cannot be directed to an external data set. To see the trace, you must generate a memory dump of the NetSpool internal storage. For more information about how to request a dump, see Dumps.

NetSpool maintains separate wrap traces for:

• NetSpool's program control.

  This includes NetSpool's startup, operator command processing, starting and stopping printer LU sessions, VTAM® interfacing, and Printer Inventory tasks.

• Each printer LU's processing of data.

  This includes the SCS and 3270 commands, orders, data flow processed by NetSpool, and record output.

For each trace, you can select a length from 4 K to 3996 K.
