|SecureFiles in Oracle 11g Database Release 1 - Compress, deduplicate and encrypt LOBs using the new LOB functionality in Oracle 11g.|
Lesio said...Perfect article !
FILESYSTEM_LIKE_LOGGING and NOLOGGING are the same for SecureFiles. The diference between FILESYSTEM_LIKE_LOGGING for SecureFiles and NOLOGGING for BasicFiles is SecureFiles will survive instance crash BasicFiles will not survive.
I think you need to clarify it in this document it could be vey useful.
Yury said...> There is no automatic method for migrating a column from a BasicFile to a SecureFile LOB.
Actually there is:
Online redefinition is the only recommended method for migration of BasicFile LOBs to SecureFiles. It can be done at the table or partition level.
Online table redefinition (which I mentioned in the article) is not an automatic method for conversion. You have to do it manually, like all the other methods I listed.
