The following error may occur when refreshing a published extract:

Connection Failure ( status code = 3000, [SQLSTATE:XX001] error opening database...: There was an error during loading database: database... has invalid checksum for object id...: Expected checksum.... The database is corrupt and needs to be re-created. Unable to connect to the Tableau Data Extract server "". Check that the server is running and that you have access privileges to the requested database. )

To make the published extract usable and allow refresh jobs to be completed successfully, re-create the extract in Tableau Desktop, and then republish the extract.
