Re: Multi-Versions and Vacuum

If Oracle uses multiple version concurrency, then why does it appear to do
row locking (I use Oracle at work, but I do not admin it)

The only downside I have seen to MVCS is the extra disk space, but with
the performance improvements in a highly concurrent use environment, it is
well worth it.

Q:  Does VACUUM FULL remove the rows that are too many for the FSM?  Or,
are they just stuck?  I know that regular VACUUM will not allow reuse of
overflowed rows.  Also, how does one calculate the propper size for the
FSM?
