UNRECOVERABLE is the 7.x version of NOLOGGING. However, UNRECOVERABLE
and NOLOGGING never worked for a DELETE statement.
If someone wrote something like:
delete from some_big_table unrecoverable;
all they did was succeed in assigned some_big_table a table
alias, "unrecoverable". ;-)

Subject: DELETE FROM table UNRECOVERABLE?
I'm seeing this statement being issued in one database. I cannot find
the
UNRECOVERABLE keyword in the 9i SQL Reference. Is UNRECOVERABLE
perhaps
an old keyword that is now ignored by Oracle?
I did some quick testing with AUTOTRACE, and noted no difference for the
values for Redo Size as compared to a DELETE w/o UNRECOVERABLE, nor did
it=20
have any impact on the HWM.
