Resizing Datafile

Hello !

    I have problem with resizing a datafile. It belongs to tablespace, that contains indexes. Thanks to informations in view DBA_FREE_SPACE I know that it contains
free space and I want to make it a little smaller.

But when I'm executing command:

ALTER DATABASE DATAFILE 'filename' RESIZE new size

where new size, is not smaller than (current size) minus (free space in file)

i receive message:

ORA-03297:file contains 22875 blocks of data beyond the requested RESIZE value

What is important, sum of this value (22875) and my requested resize value is equal to current
file size. In this moment I understand that a free space in file means nothing for this operation.

It is possible to do so ? What schould I do ?

I thank in advance for a responce
