The observation about read-only databases is a side-issue. Internal gds
software consistency check in a read-write database indicates corruption.

There is only a handful of ways to corrupt a database and restoring a
database using the -r[eplace_database] switch is one of them.

If your restore app restored to a new database file then presumably it's
the new file that is corrupt and the original is still OK. That's a
reasonably good indication that you have some corrupt structures in the

Either way, download this paper and go through the steps described. If
you're lucky, you'll end up with a database you can connect to.

database file. Do I need to remind you not to file-copy a database file
that has active connections?
