How to recover oracle tablespace dropped in archivelog database no backup?

Posted by PDSERVICE on 3月 07, 2020 In DUL

there is a oracle database with archivelog mode, and no backup. A tablespace is dropped, and how to recover?

Is there any old copy of the datafiles from the dropped tablespace. For example from a system backup or image?

If so, you may possibly be able to extract some of the data from the datafiles using Oracle DUL (search for it: Oracle Data Unload utility).
