Hi,

ok, when im right now it would work with replication if I use different
tables ? -> thats already done so, we have 3 Tables where new orders are
stored (and costumerdates etc...) - and 12 tavles where products are in -
but how could I connect them ? IN MySQL's replication FAQ and Manual its
only talking about whole servers....

Wich benefits could Oracle (or PostgreSQL) offer in this problem ?

PS: the locations cant be the same - the server with the newest Product
dates is a Workgroup server while the Internetserver is the one where
costumers order on.

If you're talking about 2 different tables, e.g.:

   i modify table a on server a and server b replicates the change
   i then modify table b on server b and server a replicates the change

then it's a piece of cake.

Two-way replication of the same table however has some gotchas,
mainly the indices - since there is a (in most cases we're talking about
milliseconds, but still) tiny lag between the servers catch up to date
again, there is a possibility of inserting conflicting entries on both sides
at the same time and replication really can't decide which one to keep.
Especially when you use auto_increment ID fields.


If you're serious about replication and advanced MySQL use, you
should consider participating in a MySQL training. The next one
in Germany is 11-15.02 at Hamburg so you yet have time :-)


Rgds,
