RE: Datafile Size

What OS are you working on??  I'm currently working with an HP-UX server
& the data file size is only off by 8K which I do believe is the header
block for the file & would not be reported as usable.

Also du -sh and ls -ltrh shows different output.
 
bash-3.00$ ls -ltrh
-rw-rw----   1 oracle   dba         1.5G Feb  9 08:09 sysaux01.dbf

bash-3.00$ du -sh sysaux01.dbf
 830M   sysaux01.dbf
 
 
SQL> select sum(space_usage_kbytes) from v$sysaux_occupants;
                 309504

        Hi Gurus,

         

        Kindly clarify my doubt on datafile size. I have noticed that
the datafile size is different from OS level vs database. When I query
to get the size of SYSAUX tablespace on database it showed me 310 MB,
But on OS it showed me 830M.

         

        SQL> select file_name,tablespace_name,bytes/1024/1024,
maxbytes/1024/1024,AUTOEXTENSIBLE

          2  from dba_data_files where tablespace_name='SYSAUX' order by
file_name;

         

        FILE_NAME

        
------------------------------------------------------------------------
--------

        TABLESPACE_NAME                BYTES/1024/1024
MAXBYTES/1024/1024 AUT

        ------------------------------ ---------------
------------------ ---

        /DATA/ORACLE/datafiles/sysaux01.dbf

        SYSAUX                                     310
0 NO

         

        bash-3.00$ pwd

        /DATA/ORACLE/datafiles/

        bash-3.00$ du -sh sysaux01.dbf

         830M   sysaux01.dbf

        bash-3.00$

         

        How this is possible?
         
        Regards,
        Naga
