HP-UX SNAplus2 Diagnostics Guide

Using Logging and Tracing
Tracing
Chapter 392
Tracing is now enabled and will be written to the following text files:
• /var/opt/sna/snacs1.trc
• /var/opt/sna/snacs2.trc
For more information about controlling client-server tracingon HP-UX
computers, refer to the descriptions of the snapadmin set_cs_trace
and snapadmin query_cs_trace commands in the HP-UX SNAplus2
Administration Command Reference. (The snapadmin query_cs_trace
command returns information about the current tracing options for data
sent between computers on the SNAplus2 LAN.) For information about
controlling client-server tracing on Windows clients, refer to the HP-UX
SNAplus2 Administration Guide.
If you are upgrading a client-server system to a new level of the
SNAplus2 software and the LAN contains a mix of servers running
current-level and back-level software, you can activate tracing on the
software component of the current-level server that provides support for
back-level computers. To specify options for tracing data sent between a
current-level SNAplus2 server and a back-level server or client, use the
snapadmin set_bck_cs_trace command. To obtain information about
the current options for tracing data sent between a current-level
SNAplus2 server and a back-level server or client, use the snapadmin
query_bck_cs_trace command. For more information about these
commands, refer to the HP-UX SNAplus2 Administration Command
Reference.
Client-Server Trace File Contents
Client-server trace data is written to the following text files (which you
can view using a standard ASCII text editor):
/var/opt/sna/snacs1.trc

The abbreviation SLM.BS at the start of each line indicates the SNA LAN
Interface Module (SLIM) for Berkeley Software Distribution (BSD)
Sockets. This process ID is followed by an indicator of the tracing type
(TCP or UDP). Each entry describes an event (such as establishing a
connection, or sending or receiving a message) and includes message
data where appropriate.
