> How would I best go about trying to fix this?

I forgot some things:
- of course I brought the database online again after backup first
failed.
- users are logging in with explicit usernames and roles. nobody and
no software is using SYSDBA besides me
- database only has 1 file (no limbo problems)

gfix -v -full reports "Number of record level errors: 1"

so does "gfix -m ... ", "gfix -m -i ...", "gfix -m -full -i ..."

after executing all possible combinations of "gfix -m", "gfix -v"
still reports "Number of record level errors: 1", and "gbak -b -g
-i -v ..." still does not get over "starting transaction".
