Some tools are easier to learn than others, but in my experience the most
difficult thing to grasp for DBAs are the concepts behind logical replication.
Logical replication is the process that all these tools use and it is VERY
different to physical replication that Data Guard uses and that we all
understand.
If you do not understand logical replication and the implications of it, a big
mess will be created even if you know the tool really well.
So make sure you understand the concepts. It is not hard, you just have to know
them.

Thank you all. Are these tools easy to learn? If it takes a few weeks to
learn, it won't sell to the management no matter how low the price tag is.

And, of course, there is Quest's SharePlex, which is tested and tried. Also
available on the time basis. I've had some experience with SharePlex few
years ago and they were favourable. As for DbVisit, I have used their
standby for standard edition product and it's an excellent product. It can
even do a switchover, just like DG Broker. If DbVisit replicate product is
of the same quality as their standby product, I wouldn't hesitate to use it.

Chen,
I would add the DBvisit Replicate product to the list. I believe it is also
available on a time basis (you can rent it).
