Hi everyone,
I have been using an embedded setup of derby (version 10.4.1.3) for
quite some time. It appears that my database has become corrupt for
some reason, possibly related to
https://issues.apache.org/jira/browse/DERBY-3725
Hi,
I'm afraid the only proper way out of this is to restore from a backup.
Another option is to post only the damaged page (or post the full
conglomerate/db itself) for investigation. You could also modify only
the format id and run SYSCS_CHECK_TABLE again, but bit-fiddling at this
level really isn't recommended...
Also, performing such an investigation is a lot of work, so I'm not sure
anyone will do it.

Is there any way to tell for sure if this issue is related to
DERBY-3725? If so, and I upgrade the database, is there a way to
repair the existing database? Is there any additional information I
can provide to give further insight?
Thank you,
