Reading Trace Output
If tracing is enabled for a device and either no SHADOW file has been specified or a
problem is encountered when writing to a SHADOW file, tracing for that device is
disabled.
Reading Trace Output
Each trace event causes two or more records to be written to a trace file.
The first record (the identifier record) contains
•
The type of event
•
The time event occurred
•
An abbreviated stack trace for the procedure that produced the event
The second record (the data record) contains data related to the event. If the amount
of data exceeds the trace record size, the data is written as two or more records.
Because the trace file is an entry-sequenced Enscribe file, it is recommended that you
use a FUP COPY command to list the trace information, for example:
TACL 1>FUP COPY trace-file-name,$S.#location,H
