Home -> Community -> Mailing Lists -> Oracle-L -> RE: free up datafile space problem ???
I just sent this to the other list...
Here is a quick script to list the tablespace/datafiles and their higwater marks, as well as generate the resize commands;
--begin script
col blksz new_value blksz noprint;
col tablespace_name for a20 heading "Tablespace|Name";
col file_name for a50 heading "File|Name"; col file_id for 999 heading "File|Id"; col file_size for 999,999.99 heading "File|Size MB"; col file_hw for 999,999.99 heading "HighWater|Size MB";set linesize 132;
select value blksz from v$parameter where lower(name) = 'db_block_size';
select a.tablespace_name, b.file_name, b.file_id, b.bytes/1024/1024
file_size,
((c.max_blockid+a.blocks) * &blksz)/1024/1024 file_hw
from dba_extents a, dba_data_files b ,
(select file_id, max(block_id) max_blockid from dba_extents group by
file_id) c
where a.file_id=b.file_id
and a.file_id=c.file_id
and a.block_id = c.max_blockid
order by 1,2;
set pagesize 0;
select 'alter database datafile '||''''||b.file_name||''''||' resize
'||round(((c.max_blockid+a.blocks) * &blksz)/1024/1024)||'M ;'
from dba_extents a, dba_data_files b ,
(select file_id, max(block_id) max_blockid from dba_extents group by
file_id) c
where a.file_id=b.file_id
and a.file_id=c.file_id
and a.block_id = c.max_blockid;
quit
--end script

Hi all,
I have a data file of 2G and the free bytes is
1,413,079, the used bytes is only 683,829. I like to
resize it. When I issue:
alter database datafile
'/orafs02/oradata/PV_A0725/ld_data05.dbf' resize
1000M, I got:
ERROR at line 1:
ORA-03297: file contains used data beyond requested
RESIZE value
But apparently, the file does NOT contain data beyond 1000M. Am I missing something?
Thank you.
Janet
