The User Trace
Formatting the User Trace
The trace file must be formatted before you can read it. On MPE V, use
the utility APPCDUMP.APPC.SYS to format the user trace. APPCDUMP
requires that you specify an input file and an output file. The syntax for
running APPCDUMP is as follows:
:FILE TRACEIN = trace file name
:FILE TRACEOUT = { $STDLIST } (terminal)
{ *LP } (printer)
{ file designator }
:RUN APPCDUMP.APPC.SYS
On MPE XL, use the NMS utility NMDUMP.PUB.SYS to format the user
trace. To run NMDUMP, type the following command at the MPE colon
prompt:
:RUN NMDUMP.PUB.SYS
NMDUMP will respond with a menu. You use the menu to indicate the
type of file you want to format and which subsystem generated the file.
NMDUMP will prompt you for an input file and an output file. The
default output file is $STDLIST. You can use a file equation to
back-reference the name of an input or output file. For more
information on NMDUMP, see Using the Node Management Services
(NMS) Utilities.
Reading the User Trace
The user trace records information for each intrinsic the local TP calls.
This section explains how to read the information in the user trace.
Figure 7-1 is an example trace of a two-way conversation.
