Tomasz said... TimFILESYSTEM_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. Regards Tomasz |
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. http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28393/adlob_smart.htm#BABDIEGE |
Tim... said... Hi.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. Cheers Tim... |
