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

KPROPLOG(8)							   MIT Kerberos 						       KPROPLOG(8)

NAME
kproplog - display the contents of the Kerberos principal update log SYNOPSIS
kproplog [-h] [-e num] [-v] kproplog [-R] DESCRIPTION
The kproplog command displays the contents of the KDC database update log to standard output. It can be used to keep track of incremental updates to the principal database. The update log file contains the update log maintained by the kadmind(8) process on the master KDC server and the kpropd(8) process on the slave KDC servers. When updates occur, they are logged to this file. Subsequently any KDC slave configured for incremental updates will request the current data from the master KDC and update their log file with any updates returned. The kproplog command requires read access to the update log file. It will display update entries only for the KDC it runs on. If no options are specified, kproplog displays a summary of the update log. If invoked on the master, kproplog also displays all of the update entries. If invoked on a slave KDC server, kproplog displays only a summary of the updates, which includes the serial number of the last update received and the associated time stamp of the last update. OPTIONS
-R Reset the update log. This forces full resynchronization. If used on a slave then that slave will request a full resync. If used on the master then all slaves will request full resyncs. -h Display a summary of the update log. This information includes the database version number, state of the database, the number of updates in the log, the time stamp of the first and last update, and the version number of the first and last update entry. -e num Display the last num update entries in the log. This is useful when debugging synchronization between KDC servers. -v Display individual attributes per update. An example of the output generated for one entry: Update Entry Update serial # : 4 Update operation : Add Update principal : test@EXAMPLE.COM Update size : 424 Update committed : True Update time stamp : Fri Feb 20 23:37:42 2004 Attributes changed : 6 Principal Key data Password last changed Modifying principal Modification time TL data ENVIRONMENT
kproplog uses the following environment variables: o KRB5_KDC_PROFILE SEE ALSO
