I suppose it depends how critical your update is to synchronise. I have a vague memory about transactions being described with a two-phase commit, however that required database links to be in place and might have been Oracle only. It was a way of ensuring that updates were prepared (actually done but not committed) on all connected databases before a follow up COMMIT was sent to all. I can't remember how you set it up or what restrictions there may be, but you might get some assistance searching for that.
Two-phase commit protocol - Wikipedia has a 'brief' outline.
What database software are you using? Versions might also be important.
Kind regards,
Robin

Hi folks. I am writing a ksh ftp script. The problem is, I need to transfer the files to several different servers. Is there a way to close a connection and move on to the next in one script or do I need to write a separate script for each one?
Thanks,

KPROPLOG(1) General Commands Manual KPROPLOG(1)
NAME
kproplog - display the contents of the Kerberos principal update log
SYNOPSIS
kproplog [-h] [-e num]
DESCRIPTION
The kproplog command displays the contents of the Kerberos principal update log to standard output. It can be used to keep track of the
incremental updates to the principal database, when enabled. The update log file contains the update log maintained by the kadmind process
on the master KDC server and the kpropd 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 principal.ulog file
with any updates returned.
The kproplog command can only be run on a KDC server by someone with privileges comparable to the superuser. It will display update
entries for that server only.
If no options are specified, the summary of the update log is displayed. If invoked on the master, all of the update entries are also dis-
played. When invoked on a slave KDC server, only a summary of the updates are displayed, which includes the serial number of the last
update received and the associated time stamp of the last update.
OPTIONS
-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
