DCPTRACE −− SmartSync/DCP Trace Dump Utility
This program is used to access the line trace buffers updated by
SmartSync/DCP BSC processes. This utility is strictly for diagnostic
purposes and should only be used under the direction of Serengeti Technical
Support. You must turn on line trace from within 3780Link, but the dumping
of the line trace information is handled by running Dcptrace thereafter.
The trace data retrieved by Dcptrace is automatically written to both the
screen and an output file. If you've configured one SmartSync/DCP, the
default file name is “trace. x” where x is the port number. If you've
configured more than one board, the default file name is “trace.xy” where x is
the port number and y is the board number. By default the output file is reset
when it reaches 100,000 bytes. This enables Dcptrace to run continuously
without overflowing disk storage. The optional command line switches for
Dcptrace are described below:
-b board Board number to trace [1-6]
The -b switch specifies which SmartSync/DCP Dcptrace is to access. The
board number corresponds to the order in which they were configured. If
omitted, Dcptrace defaults to board 1.
-p port Port number to trace [1-8]
The -p switch specifies which of the SmartSync/DCP ports to monitor for
trace data. If omitted, Dcptrace defaults to monitor port 1.
-f name Alternative trace file name
The -f switch specifies a file, other than the default, to record trace data.
-m size Maximum size of trace file (kilobytes)
The -m switch changes the default maximum output file size. By default the
trace file is reset when it exceeds 100,000 bytes. To change this default,
specify the maximum file size in kilobytes (1,024 bytes). For example, -
m50 establishes the maximum file size to be 50K bytes.
