Home -> Community -> Mailing Lists -> Oracle-L -> RE: Corrupted data blocks in tablespace SYSTEM
Kevin,
Try exporting your schema owners (code, tables, etc.) as a CYA. When you recreate the db, you can import each schema separately. A pain, but it will save you.

I have attempted a full export and received the following message:

Since the corruption resides in the SYSTEM tablespace, it seems that the course of action that should be taken is to re-create the database.

Kevin,
Check DBA_EXTENTS to see what kind of segment is corrupted. If it's a table or a cluster, you have lost. Otherwise there is a chance to recover the database. In any case try a full export.
