Coolbhai,
If the way your application was designed, it is appending to the file
each microsecond, you must take the risk of loosing some data whenever
you refresh the log file.
If you are appending, then if the file does not exist, the append
will create it.
Here is one possible solution if you want to save the file:
Code:
mv Big_File Save_Big_File

If you do not want to save:
Code:
tail Big_File > Big_File

NAME
nislog - display the contents of the NIS+ transaction log SYNOPSIS
/usr/sbin/nislog [-h num | -t num] [-v] [directory...] DESCRIPTION
nislog displays the contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are logged to this file and then propagated to replicas as log transactions. When the log is checkpointed, updates that have been propagated to the replicas are removed. The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only. If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified directories are displayed. OPTIONS
-h num Display num transactions from the ``head'' of the log. If the numeric parameter is 0, only the log header is displayed. -t num Display num transactions from the ``tail'' of the log. If the numeric parameter is 0, only the log header is displayed. -v Verbose mode. FILES
