Fellow list members, I received the following email from a reader a few minutes ago. If you skip down to where he talks about backup, you'll see that he's in trouble with a database that won't recover. I've already suggested that he open a TAR, and that he supply more specifics as to error messages and the like, but maybe someone on this list can draw some conclusions from what he's told me so far. If you're good at recovery, have a look at what he says. I'll post his email address later if he says its ok, and I'll pass on any advice/suggestions I receive in the meantime.


Best regards,

Jonathan Gennick * 906.387.1698 * *
