Hello All,
We did Online DB table reorg in the production system and it reduced 152GB at table level but not refelected in the os level. During this
activity we added 300GB to the tablespaces to perform the DB reorg and
increased the DB size from 3.4 TB to 4 TB
Our intention is to reduce the space at file system level.
Please confirm what steps we need to perform in order to release space
at filesystem level
1) By doing offline reorg at Tablespace level
2) By doing export/import database using system copy methods
3) By doing shrinking the database after completing online table rerog
(online/offline)
