Keeping 2 db updated each-other

Hi,

I need to keep updated to databases (little ~ 100.000 record splitted in 15
tables). Is there any general tip?

Since the database is handles via tcl-tk I'm logging all
update/delete/insert so as to pass the whole bunch of 'not yet updated'
statement to the database that needs updating. This requires having all
statements referenced w/ primary key becouse OID are different on different
hosts. This seems to work but is quite tricky.

Is there a better solution?

Thanks in advance
