trace for the first time.The Barr trace facility implements the SNA Server or HIS trace facility to record detailed information about the software events surrounding an error condition. The Barr trace facility automatically gathers and compresses the trace information into a single file for you to provide to Barr Technical Support.
Use the Tracing tab to start and stop the trace. After you start the trace, click OK from the Tracing tab and recreate the error condition or the activities for which you want to gather information.
The Barr trace facility uses the SNA gateway trace facility to gather information about the following activities.
Data Link Control (DLC) – SNA-formatted data that the SNA gateway gives to the BARR/CHANNEL link service to send on the link.
Level 2 messages – Link activity reported by the device driver and CDLC events and data frames.
Internal tracing – Messages showing internal states and conditions within the link service.
The Barr trace facility adds registry information and event logs to the SNA gateway trace facility. Then it compresses the data into one file for you to provide to Barr Technical Support.
