Home -> Community -> Mailing Lists -> Oracle-L -> RE: REPLICATION/FAIL OVER
Seema -
I have only done just a little testing of replication, so I'm hardly the expert. I believe the answer to your question is yes. You can make db1 the master site for the 4 tables and db2 the master site for the 3 tables.
The bigger question is whether changes can be made to these tables from either side. If the answer is no, then simple snapshots will be sufficient. If the answer is yes, then you must look at how the application is designed. Can you make changes to the application to avoid problems in replication?
But people tend to approach replication with a set of ideas and then find that they must change those ideas as they learn more. Oracle Replication is not a high-volume method, so you must have a good handle on how many rows will get changed each day.
A good book is "Oracle Distributed Systems" by Charles Dye.

I want to do sync 4 tables from db1 to db2 and 3tables from db2 to db1.
If i make one server as master server then is it possible to make secondary
server(snapshot server) once and vice versa.
Thanks
