Have no experience with realtime replication. How realtime is it (ns, ms, minutes...). Is it realtime part oneway (oracle+msql) to ms sql server?

This is really funny, just a couple of days ago somebody mentioned SymmetricDS as a viable solution when talking about heterogeneous replication.

I don't see how real time replication of data from an Oracle Server to and SQL Server is going to do that. If you want to reduce licensing of Oracle, you'll need to physically cut down on Oracle Servers. That means a migration of apps from Oracle to SQL Server.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
     Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

They need MS SQL to generate report from multisource such as MySQL and ORacle. It's one way replication. Normally, i've seen from GoldenGate but the interesting story's using MS SQL. Microsoft guy used to tell me about replication from Oracle to MS SQL, 's simple by DTS.

Thank you for comment, but political in ORG plays an important role for big change.

Ok, and understood but what does that have to do with reducing licensing of Oracle Servers like you asked?
