Shulou(Shulou.com)06/01 Report--

Yesterday, the business department responded to the need to delete the fields of a table and thought about setting the fields to the state of unused, which is very convenient to restore if needed. This morning, it was found that there was a failure in OGG data replication, the main library EXTRACT process appeared ABENDED status, and the data was not synchronized. Viewing from the OGG log is a problem with the field UNNUSED.

Log exception

Please use 'DBOPTIONS ALLOWUNUSEDCOLUMN' parameter to override this., try to fix this issue in order to avoid possible fatal error.
