Temporary replication of data between continental datacenters I need a way to temporarily replicate data between two data centers on two continents for a small number of large tables in Oracle. The data in the tables is around 30Gb but the transfer rate is only around 5Gb/hour.

I guess that the data does not change greatly on a day to day basis.

What options do we have for replicating the data that are simple and cost effective for this short term requirement?

Clarifications


Temporarily i.e. two months
A subset of the database, 2 or three large tables
One way, until the database is migrated to the new datacenter
Of free solutions, I can only think of rolling your own with a trigger over a database link, or setting up streams.

I'd set up streams.
