General questions
beginnergirl 28.08.2006 20:46:02
It's probably already out there but I can't see where anyone asks:

1. Does the synchronization process matter in what order you do it? Seems
like depending upon the order, I've lost my Master Design. I've become quite
the expert at recreating it but I'm tired of doing so.

2. Why, once I have synchronized replicas with the Master design and made
new replicas for the users, are their files sizes different? There doesn't
appear to be missing data but I'm being asked and I just don't know why.

Why would you *ever* lose your DM? Makes no sense to me at all.
You'd only lose it if you check the box to make the target replica
the DM, but why would you do that if you hadn't lost the original
DM.

Last of all, you shouldn't be synching often with the DM, or using
it for production editing. The DM should be kept aside and used for
one purpose: making design changes to the data table schema. You
need to synch with it every month or so to make sure that it doesn't
expire, but you shouldn't have frequent synchs with a DM unless
you're in the early development stages where your data schema is
still in flux.

If you compact them after the synch (twice if there was a design
change during the synch) they should all be the same size. This just
a basic compact issue, not a replication issue.

Okay....here it goes....

RE: Design Master
I'm not really sure how I have occassionally lost my DM. The only time I
have clicked on the button is when I have to make a new Design Master. But
the reason that I have been sync'ing with it often is because we are on a
lengthy project and each time we visit one of our stations, there has been a
need for changes/corrections/updates so that in the end the data will be
easily extractable. We are only on our 2nd station visit and have about 5
more to go through January.

RE: File sizes

I do the compact/repair prior to making the new replicas for the users but
their replica files sizes seem to be different (not by much). I just have
the users asking me why and it makes them worry that data is being lost
although I have carefully researched this and there is no loss of data.

Are you carrying the DM with you? If that's the case, then that
explains why you're losing your DM. You simply cannot synch with any
replication except in its original permanent location. Putting a DM
in a different location makes it a replica, in all circumstances.

Read the Access help file on compacting. What you've written above
leads me to believe that you might be confused about the role
compacting plays in an MDB -- the size a replica starts out is
simply irrelevant. It will grow as data is edited and changed,
though much of that growth will be in temporary data pages that are
marked unused and will be removed when the MDB is compacted.

Thanks so much for your help. I actually had read that the compacting is
what removes all of the unnecessary stuff that takes up space so that part I
do understand but will certainly take your advice and do more reading.
