Server Administration :: Size Storing JPG File In Database
Feb 13, 2012
I am storing customer's snaps in a table ( column's data type as LONG RAW) using oracle forms Webutil. Now there are 250 snaps in the table. The file type of these snaps is JPG with the average size 30KB.
I made a backup using export utility before storing these snaps and the exported DMP file's size was 36MB. Now after storing these just 250 snaps of 30KB the DMP file's size is gone over 300MB.
i need to change column's datatype? or some where in oracle forms's image item. Because on window's file system the size of these files is just 8MB.

I noticed my DB is generating a lot of "small" .arc files and I am usure why. As you can see from the v$log query my log file size is set to 50MB. But yet BLOCKS*BLOCK_SIZE never adds up to 50MB.
Is there anything else I can look into to see how to make the .arc files larger?

What's the maximum size of the control file in one database ?
i calculated it according to the following steps:
SQL>SELECT (BLOCK_SIZE/1024/1024)*20000 MB FROM V$CONTROLFILE WHERE ROWNUM = 1;
MB
------
312.5
The maximum number of the data block in one control file is 20000.

I have Oracle 11gR2 running on windows xp machine. Windows xp has total size of 150 GB and free space of 95 GB.
I checked the size of the database that I created. It showed the total size of the database as 2 GB and used space as 2 GB. If I want to increase the total size of the database to 50 GB, what should i do? Now which is the disk space size? Windows or Oracle?

I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.

Our database size is 100GB and i removed few records from a table and rebuild the index.The size of Index reduced considerably after Index rebuild but now i see our database size increased to 115GB.I know online rebuild creates second index which is also removed after the build is finished then why the increase in database size?Is there a way so it shows up more space ?
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1';
8GB
ALTER INDEX abc_index_1 REBUILD ONLINE ;
select sum(bytes) from dba_segments where owner='abc' and segment_name='abc_index_1';
2GB

I was surprised when I shutdown our production dB. I got this error:
$ . oraenv
ORACLE_SID = [abcd] ?
SQL> shutdown
ORA-01116: error in opening database file 26
ORA-01110: data file 26: '/VOL03/oradata/qxyz/data/qxyz_data01.dbf'
ORA-27041: unable to open file
SVR4 Error: 2: No such file or directory
Additional information: 3
SQL> shutdown abort
ORACLE instance shut down.
2 days ago i rename this file QXYZ_DATA01.dbf from it's original name of QXYZ01.dbf without knowing that I was in the 'abcd' instance. When I backup a controlfile I noticed that it was part of the 'abcd' data files, so I just delete it (from OS level).
Is there any risk involved in the 'abcd' instance? How do I get rid of that file 'qxyz_data01.dbf' in the 'abcd' instance.

I am working to understand the space allocation of table with the value we provided with the data type. For that I have created a table with varchar2 and length 50. Size of table created is of 65536 Bytes. This is when we don't have any insertion in the table. Later when we insert some rows, total size if the segment still remain same that is 65536 bytes.
Now again when I created table with varchar2 and length this time is 500 but still it is created with same size that is 65536. So can you just explain, on what values segment size depends on and how the length effect the size & space allocation.
db_block_size is 8192.

I am writing a program for doing some file transfer between the client machine and the application server.I am using Webutil_File_Transfer.Client_To_AS to do the transfer and also using Webutil_File.File_Size to check on the file size at the source.
Once the transfer is complete, I also need to check on the destination file size (the application server running on Linux) for verification purposes and can't find the way to do it.

The problem is that the data of the table are 40GB while on the DB the table holds 400GB! How can I shrink and reuse that space except from drop/recreate and drop/import?
The table has no initial data, so that I can play with the INITIAL parameter. Data are inserted, updated and deleted all the time. I have run DBMS_ADVISOR which recommended to SHRINK table. I have performed the shrink :
alter table STG_XML shrink space COMPACT;
but I haven't gained any space.

As the undo segments are used in round robin fashion, Is it possible that with varying load (concurrent users, size and number of transactions), the size of Undo tablespace on a particular day is less than the Undo tablespace size few days back, by any chance?
As a basic understanding I know that Undo is preserved for read consistency and transaction, instance recovery So if there are lot of transaction on a database on 05 Feb and before that, but there aren't any transactions on 6,7,8,9, then on 10th Feb can we see the Undo tablespace size is less than that of 05 Feb?
In the following case when data belonging to table is not required for any queries, transactions, even then the undo size is not restored upon dropping the table.
As such for large operations and batch processes shall we keep undo tablespace with files as 'Autoextend' with 'Maxsize' as 'Unlimited'?
SQL> select b.tablespace_name, Total_Kbytes_Available/1024 Tot_Mbytes_Available,
Kbytes_alloc/1024 Mbytes_allocated, kbytes_free/1024 Mbytes_Free_from_allocated,
((Kbytes_alloc - kbytes_free)*100/ Total_Kbytes_Available) Pctused
2 from ( select sum(bytes)/1024 Kbytes_free,
3 tablespace_name
4 from sys.dba_free_space

One of our solaris machines is running Oracle 8.0.3
A table reached the 2 Gb size and oracle failed due to the operating system file size limitation.
The information in the table is not relevant and can be deleted, but the table contains a lot of indexes.
I would like to know the best procedure to delete the information and reduce the size of the file.
