Managing SNAplus2 Clients
Managing Win16 Clients
The full path name of the trace file, or of the first trace
file if tracing is to two files (see the description of the
file2 parameter).
This parameter is required if you want to enable
message tracing; you also need to set the fmi
parameter.
file2
The full path name of the second trace file. This
parameter is optional. To indicate that tracing is to one
file instead of two files, do not include this line.
If both file1 and file2 are specified, tracing is to two
files. When the first file reaches the size specified by
flip_size, the second file is cleared, and tracing
continues to the second file. When this file then reaches
the size specified by flip_size, the first file is cleared,
and tracing continues to the first file. This ensures that
tracing can continue for long periods without using
excessive disk space; the maximum space required is
approximately twice the value of the flip_size
parameter.
flip_size
The maximum size of the trace file. If two file names
are specified, tracing switches between the two files
when the current file reaches this size. If only one file
name is specified, this parameter is ignored; the file
size is not limited.
This parameter is optional. If it is not specified, the
default is 100000 (bytes).
truncation_length
The maximum length, in bytes, of the information
written to the trace file for each message. If a message
is longer than this, SNAplus2 writes only the start of
the message to the trace file, and discards the data
beyond truncation_length. This enables you to record
the most important information for each message but
avoid filling up the file with long messages.
This parameter is optional. If it is not specified,
SNAplus2 does not truncate messages (all the data
from each message is written to the file).
