Just read thru Girlgeek's Blog about RAT. This is a feature which i have been very interested in ever since it was announced and share the same skeptism that she does. In this age of HIPAA,SOX etc what use is RAT if masking cannot be done . this would ensure my offshore developers have all my production data. The one ability i would so like to get RAT for is the ability to test upgrades. For some OLTP applications it is virtually impossible to account for the network latency and the volume . RAT has the potiental to solve that but since i have not seen any documentation or tried it out yet. I'm guessing RAT cannot be used in Lower Database e.g 9 or 10. Making it available to those database as a collector might be so beneficial to a lot of DBA's who aim for a smooth upgrade.
