We have a customer where it looks like their database and all their backups
are corrupt.
I am seeing a "checksum failure on page 11661" error when unloading the
database.
Is there a way to unload the db so that dbunload ignores errors and just
continues with the unload?
I was able to unload the entire db except for one table. This table happens
to be the largest in the db.
This customer's production db is now down.
Thanks,
Doug

Doug,

you might want to try the UNLOAD SELECT statement with an ORDER BY ...
until it stops with the error. Then try a second time with the reversed
order (ASC replaced by DESC or vice versa). With some luck there'll be
only a small window of missing rows.

Of course there's always the chance to open a support case with Sybase
for data salvation, they got tools to dig deeper than we users.
