Thanks Roger. Run query against flashback_transaction_query takes a while, it returns over 12 hours transaction.

Our problem is caused by an Oracle apps patch, now Oracle ask us to apply another patch to fix it. If this will not work then I would do the recovery.

Thanks again for the help.

DBA_TAB_MODIFICATIONS describes modifications to all tables in the database that have been modified since the last time statistics were gathered on the tables. Try flashback_transaction_query ...

Thanks Julio.

dba_tab_modifications returns no rows with today's timestamp :)

Try dba_tab_modifications. It has columns such as the table_owner, table_name, number of inserts/updates/deletes, and the timestamp.

Hi DBA gurus,  

I need to flashback our EBS database to 10 hours ago, also hope the last five hours data can be recovered with export/import. Is there a way to find which table's/schema's data has been changed in last five hours, so that I could export the schemas/tables before flashback and import them after flashback?  

Thanks,

Lu
