Forum OpenACS Q&A: Response to Oracle problem - any ideas?

Yes, if things broke because Oracle didn't write a transaction to the
redo log properly during an import, well, that sounds like exactly the
sort of thing using Oracle is supposed to avoid, doesn't it?  But if
Oracle crashed, then maybe all bets are off - not good.  I don't
remember enough about how the control file is supposed to interact
with the redo logs to guess what's really going on there, though.
Definitely sounds like one to open an Oracle TAR on.  Please let us
know if you get any useful info out of them!  (And whatever else you
figure out yourself, of course.)
