Traces
Two types of traces can isolate a DECnet SNA Gateway for Synchronous
Transport problem:
•
Gateway Management traces
•
IBM traces
Section 3.1 describes the Gateway Management traces and Section 3.2
describes the IBM traces. Each section lists documents that provide
additional information about a particular type of trace.
3.1 Gateway Management Traces
The gateway management software provides a protocol trace utility called
SNATRACE (for Phase IV), and Netrace (for Phase V). This utility shows
the SNA protocol exchange between a Gateway-ST node and an IBM node.
You can use SNATRACE (or Netrace) to isolate problems associated with the
Gateway-ST and its access routines. For information about using SNATRACE,
refer to the
DECnet SNA Gateway-CT and ST Management book.
3.1.1 Types of Traces
You can use three types of Gateway Management traces to isolate problems in
the DECnet SNA environment.
•
Circuit level trace
•
Physical unit level trace
•
Session level trace
Choose the type of trace according to the type of problem you have. If you
do not know which trace level is appropriate for a problem, run a circuit
level trace (it is the lowest level trace and collects the most data).
