Oracle DUL with Encrypted Tablespaces

Question for the masses regarding DUL and encrypted tablespaces…I see on the main DUL page “Encryption, had a look at it recently it is discouraging complex” Does this mean that DUL cannot be performed on these types of tablespaces? Interpreting that statement would suggest that it is not but, hey I have to ask….


Indeed that means that it cannot be done with DUL.

Tablespace Encryption is in fact designed to stop an intruder from deciphering backups/copies, and it does a pretty good job at that. Also it is difficult to research as the relevant code lacks all tracing, as such tracing would be a big security hole.
