Client-Server Tracing

Client-server tracing records messages that ﬂow between SNAplus2

servers in the same domain and between the SNAplus2 server and a

client. Tracing can be activated on the data ﬂowing between two speciﬁc

computers or between one computer and all other servers on the LAN. It

can be active on either sent or received data or on all data. The following

section explains how to perform client-server tracing using the Motif

administration program and the command-line administration program.

Performing Client-Server Tracing Using the Motif

Administration Program

To perform client-server tracing using the Motif administration program,

complete the following steps:

Step 1. Enter xsnapadmin from the command line to start the Motif

administration program and display the main window.

Step 2. Select the Diagnostics menu, then select Node tracing. The Tracing

dialog is displayed.

Step 3. Select client-server to turn on tracing of messages sent between this

server, its clients and the other servers in the domain.

Step 4. Optionally, select

Truncate messages

and enter the maximum message

size, in bytes. This can be helpful if a large amount of data is being

traced and you are interested in the protocol exchanges rather than in

the data itself. Protocol data is usually at the start of the individual

messages.

Step 5. When you are ﬁnished, click OK.

Tracing is now enabled and will be written to the following text ﬁles:

• /var/opt/sna/snacs1.trc

• /var/opt/sna/snacs2.trc
