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,

commit_prepared
COMMIT
PREPARED(7) PostgreSQL 9.2.7 Documentation COMMIT PREPARED(7)
NAME
COMMIT_PREPARED - commit a transaction that was earlier prepared for two-phase commit
SYNOPSIS
COMMIT PREPARED transaction_id
DESCRIPTION
COMMIT PREPARED commits a transaction that is in prepared state.
PARAMETERS
transaction_id
The transaction identifier of the transaction that is to be committed.
NOTES
To commit a prepared transaction, you must be either the same user that executed the transaction originally, or a superuser. But you do not
have to be in the same session that executed the transaction.
This command cannot be executed inside a transaction block. The prepared transaction is committed immediately.
All currently available prepared transactions are listed in the pg_prepared_xacts system view.
EXAMPLES
Commit the transaction identified by the transaction identifier foobar:
COMMIT PREPARED 'foobar';
COMPATIBILITY
COMMIT PREPARED is a PostgreSQL extension. It is intended for use by external transaction management systems, some of which are covered by
standards (such as X/Open XA), but the SQL side of those systems is not standardized.
