Alexandre - Thanks for posting the link. I read the document. It describes how to track the DDL statements. Unless I overlooked something, it doesn't say you can UNDO DDL. I think the reason was explained earlier on this post, that Oracle doesn't write any redo records. For example, in the case of a DROP TABLE statement, in order to undo that statement, Oracle would have to write the equivalent of a DELETE statement for each row. This could be enormous if the table was large, and take a long time. Then we DBAs would be clamoring for a parameter that would bypass all that. I could be wrong, which is why I respond to issues like this.
