Just as a point of reference, I have an 11.2.0.1 db that is about 9 TB in size, almost all of which is due to a table of about 800 million rows, with an XMLTYPE column stored as securefile LOB.

Securefile LOBs are working fine for us.

I don't see this as Oracle trying to hide anything, but rather allowing the DBA to choose whether or not to use SecureFile LOBs in their environment. I wouldn't implement anything into a production environment, but in reading the benefits over BasicFile LOBs I don't see any reason to shy away from this new feature. > > Bill > On Jan 10, 2011, at 11:20 PM, Leyi Zhang (Kamus) wrote: >
