RE: Nologging clause

Again, thank you. The next question I have is in regards to deletes. Is it possible to do a direct path delete (does that even make sense)? As I mentioned this will be a repository for CAS tickets and they will be deleted at their expiration time. Is it possible to avoid generation of redo on a delete as well?

This is correct. The [NO]LOGGING only changes direct path operations. That is, inserts with the /*+ APPEND */ hint.
So if you want NOLOGGING you need either:
- NO ARCHIVE LOG mode
- ARCHIVE LOG mode, NOLOGGING, and APPEND hint
