Hi, We have an Oracle 10.2.0.1 database on RHAT4 test server and I resize the file from 100G to 30G and operation is successful and I can see in the dba_data_file it is showing now as 30G but on hard drive/filesystem it is still showing 100G. So I assumed OS may release space when other process needs it but it didn't happened and other process failed for space reasons and also I rebooted the server but still no effect. What can be the possible reasoning for this behavior and how to reduce the size at file system level. Thanks --Harvinder -- //www.freelists.org/webpage/oracle-l
