Tracing
This section explains how to use SNAplus2 trace facilities to collect
diagnostic data while the SNAplus2 system is running and how to
produce trace output.
NOTE Turn tracing on only when you are requested to do so by support
personnel or when you need the trace output to diagnose a problem. At
other times, turn off all tracing because it degrades system performance.
You can use either the Motif administration program or the
command-line administration program to do the following:
• Enable or disable line tracing for various link types.
• Enable or disable client-server tracing.
• Enable or disable internal tracing.
API tracing can be enabled or disabled for the APPC, CPI-C, LUA,
HLLAPI, MS, CSV, and NOF APIs. Usually you set up API tracing using
the SNATRC environment variable, but occasionally you may need to use
a combination of environment variables, verbs, and program functions to
do this.
Figure 3-1, “Tracing Interfaces,” shows the interfaces where each of the
main types of tracing occurs in the overall structure of SNAplus2.
