Notes

The trace function dynamically allocates a SYSOUT file to receive the trace data. This SYSOUT file's class is defined through the DUMPCL parameter of CA XCOM Data Transport's Default Options Table (see the CA XCOM Data Transport for z/OS Administration Guide). It can be overridden in the EXEC PARM of the CA XCOM Data Transport started task.

Turning on the XTRACE seriously degrades performance.

To turn off the trace, use the NOXTRACE command.
