Hi,
I have a tablesopace with 3 datafiles, out of which one datafile has corrupted block. But no objects or data is affected as the corrupted block os in free space. This was shown in the alert logs.
Please see below the details:

================================================================
The corruption is being reported in a free space block of the ORDER_DATA_01.DBF.
I’ve checked all the tables (and indexes) in this tablespace and none report corruption.
=====================================================
Is there any action I need to take to remove corruption at this point?It is not affected any operation on the database yet.
What is the best way to do get rid of the corrupt block, without dropping and rebuillding the full tablespace(which is around 6 GB -total of 3 datafiles)
Thanks a lot
