    Few useful scripts:
    BlockMap - tablespace - whole Tablespace gap
    blockmap - datafile - Gap in datafile
    Datafile Segment Map - Objects in datafile
    Object at end
    Maxshrink.sql - How much you can reduce

    You have objects at the end of datafile, which prevents this tablespace from resize. Identify those objects, move those objects, and then you can resize datafile.

    Hello Team,

    I am facing issue related to Operating system level space issue for /u01 partition. we are using oracle 11g EE.  While checking tablespace  space, I found one of my tablespace datafile showing 14G in DB as well as OS level (datafile). While checking the free space I found that the Tablespace is 99% free.

    Please find steps that I followed to release space.

    1. Truncate table that was carring huge data.
    2. shrink the table with shrink space compact parameter.
    3. shrink tablespace as per 11g features
    4. tried to resize the tablespace but it can resize till 13G only. but mesuring the free space it shows 99% free.

    Is there any way to reclaim free size from tablespace as Os level my /u01 partio

    Thanks & Regards,
