Question on Replication

Hi,
I just went through the install notes on erserver1.2 and saw a mention
in there that every table for replication requires a integer based
column. It also states that a new column is added for every table that
is replicated.

The tables I intend to replicate already have such a column. Can the
server be configured to use these instead so that the tables on both
server remain unchanged ?

What is the overhead in using replication and what is the timing of the
replication. I have a database and we add roughly 100k records during an
update operation.

I did not find a lot of information on that except 2 small documents in
distribution. can anyone point me to the site where there is a detailed
description?

Thanks
Alex

Yes. I recently posted a brief discussion of how to do this to the
erserver list. The archives are available on the gborg site.

You will need lots of memory. The replication canot happen, of
course, before the transaction commits. You may find that it will
not keep up to 100k records in a single snapshot, unless you do that
infrequently.

I suggest checking the mailing list.

I have a TSQL script to add daily tables to replication and then run the snapshot agent to distribute them to two subscribers. The script executes without errors, but when I check the running jobs for each server I see the following: JUST AN EXAMPLE Job1 'Category' REPL-Snapshot Job2 'Category' REPL-Distribution What is the difference between these two categories? Also 'Job1' works

If I have two tables that I want to synchronize via replication publish subscriber model and they don't contain primary keys i.e. an ID field, but there are three columns that make a unique key. The tables are HUGE so I want to minimize down time. Can replication still be done, either snapshot, transactional, or merge? Again I don't want to create any more columns in the tables because of the record volume. Thanks

Hi, I've been using an Access application I wrote for an office with the front-end stored on all computers and the back-end on one of them serving as an Access file server. Now we're moving to a 2nd office 15 minutes down the road. Only one office will be open at a time, so theoretically it'd be possible to copy the back-end manually every night from one office to another, but frankly, that's pretty annoying.

Hi, I set up replication with a Frontend/Backend database set up.
