I have been looking at this myself and was turned onto EnterpriseDB which
has a nice replication server.  I want all my stores using the same central
database and the local database only when the internet breaks.
EnterpriseDB's replication server works for that.  Somewhat costly, but not
nearly as bad as Oracle.

Just gotta add (maybe it's already there?) some failover logic.

Subject: POS Setup


I am having trouble figuring out the "step by step" process to deploy
POS with synchronization.

First area of clarification - How do I get the various pieces deployed
and talking to each other? I have reviewed all the documentation I can
find, and also the related config files. Here is what I understand so far:
1) Setup all the necessary entities (stores, facilities, products,
pricing, etc.)
2) Create POS sync settings to define what entities will be synced
(example PosSyncSetting.xml)
3) Define terminals per example DemoRetail.xml
4) Set entity-sync-rmi in serviceengine.xml file
5) Schedule the sync service

So where do I do each of these? Master server, per store server, pos,
all of the above? For example, if I have a configuration of one store,
one pos terminal in the store, and one central server I want the flow to be:
Push product, pricing, etc from central server down to POS terminal:
MCS -> PSS -> POS

Pull transactions from POS terminal to MCS:
POS -> PSS -> MCS

So let's start with the central server as the majority of setup will
occur here. The main question I have about the central server is, how
does it know where to "Push"? There is only one setting in
serviceengine.xml for entity-sync-rmi. So how do I configure multiple
per store servers? Or do I misunderstand the use of "PUSH" in the config
file? Is everything really "Pull?" So we just point each deployment to
the server where it should communicate? For example the POS terminal
would always be configured to talk to the PSS, PSS to MCS?

Is it necessary to use a PSS, or can we go straight from POS->MCS?

And for those of you also trying to come up to speed on POS, here is the
glossary:
MCS = Main Central Server
PSS = Per Store Server
POS = Point of Sale
