Is it better to store the image in the database or to use BFile

Hi all,
I've a doubt regarding the handling of the image. For example i've the images of the persons amounting to 50,000(the number will be increased in future). So i just want to know which is the better menthod. is it better to store all the images in the database or to store in local OS and use Bfile concept. I'm using Forms 6i and Forms 10g(10.1.2.0.2). OS: Windows XP

But the total number (i.e.., 50,000) is scaring me to use the BlobI don't think the database will cause problem just due to the amount of data stored in blobs. Of coure you would have to check which parameters to set for the blobs to make storage efficient. If
You didn't mention your db-version, in 11G you could also think of using compression and deduplication to deal with the data amount.
In general i agree with Francois, the best way depends, but in terms of data consistency and easy backup/restore there might be some advantages in using the blob-version.
hope this helps.

Which is better datatype for storing Images in 11gr2 Database ?

Can anyone tell me which datatype should be maintained for storing images in database in terms of
1. Space
2. Speed.
And, Is there another way for storing images instead of database ?
Thanks/Regards in advacne.

Which one have better speed, database system or file system ?Database is better all around. It is not just a question of speed. It is a question of storage, security, flexibility, scalability, robustness and so on.
If you use ASM and raw devices from a storage array or SAN, how do you get o/s files onto that? (requires a file system on the SAN/array LUNs)
If it is inside the database, database security, concurrency and consistency apply to the image. Outside the database? How do you control who has access? Prevent someone with slippery fingers from accidentally deleting/renaming/moving images files? How do you backup up the image data with the image attribute data in the database?
Having all this inside the database, part of the database, managed by the database, provides you with more flexibility, robustness, and security. After all a RDBMS is a data management system - it is designed for managing data. And that includes managing binary data.
As for speed. Reading a 24MB image is reading 24MB worth of data. Whether that data is read by process A from disk1, or process B from disk2 - the amount of data is the same. So if you want faster I/O, then use faster disks. If disk1 is faster, process A will perform better reading the image than process B. If disk2 is faster, the roles are reversed.
So I/O speed is not a direct function of process A or process B. It is a direct function of the I/O storage and fabric layer. Yes, a process's method of I/O can make a difference (e.g. using block reads not aligned with the physical blocks on disk). But this is more a configuration issue than process doing badly designed I/O calls.
So the speed question is a bit loaded as it has more to do with the architecture and design of the I/O system - and less to do with the process doing that I/O. You can have a highly optimised I/O process doing poorly using an old and slow I/O layer, and poorly written I/O process doing pretty well on a SSD I/O layer.
Databases like Oracle is designed for dealing with data - and thus effectively dealing with I/O. Lots of it. For lots of data. So I/O process design is not a consideration. The database processes will use the I/O layer as optimally as possible and as configured.

Error - Exclusive access could not be obtained because the database is in use

I am actually trying to make a script (in Sql Server 2008) to restore one database from one backup file. I made the following code and I am getting an error -
Msg 3101, Level 16, State 1, Line 3
Exclusive access could not be obtained because
the database is in use.
Msg 3013, Level 16, State 1, Line 3
RESTORE DATABASE is terminating abnormally.
How do I fix this problem ?
IF DB_ID('AdventureWorksDW') IS NOT NULL
BEGIN
RESTORE DATABASE [AdventureWorksDW]
FILE = N'AdventureWorksDW_Data'
FROM
DISK = N'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\Backup\AdventureWorksDW.bak'
WITH FILE = 1,
MOVE N'AdventureWorksDW_Data'
TO N'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW.mdf',
MOVE N'AdventureWorksDW_Log'
TO N'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW_0.LDF',
NOUNLOAD, STATS = 10
END

Check, if there are existing connections to the database you are restoring by following command
select spid from sys.sysprocesses where dbid = db_id('AdventureWorksDW')
if you see any existing connections then kill them by issuing KILL command Syntax for kill is
KILL <SPID>
once you see there are no more connections then
Use mastergoIF DB_ID('AdventureWorksDW') IS NOT NULL
BEGIN
RESTORE DATABASE [AdventureWorksDW]
FILE = N'AdventureWorksDW_Data'
FROM
DISK = N'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\Backup\AdventureWorksDW.bak'

Mark as answer, if it works.

If you don not have any process running on your pc that uses your database like Enterprise Manager or any other third party application, use
SqlConnection.ClearAllPools();
in C# code before restoring. Like the following code:
Code Snippet
public void BackupAndRestore(string Query)
     SqlConnection.ClearAllPools();
SqlConnection connection = new     SqlConnection(ConfigurationManager.AppSettings["ConnectToMasterDB"]);
     SqlDataAdapter da = new SqlDataAdapter();
     da.SelectCommand = new SqlCommand();
     da.SelectCommand.Connection = connection;
     da.SelectCommand.CommandText = Query;
     da.SelectCommand.ExecuteNonQuery();

Edit the database that RH10 uses to generate the CPD file

Is it possible to edit the database that RH10 uses to generate the CPD file? I've got one weird entry in the topics list in the Project Manager pod. I've deleted the CPD file and let RH10 rebuild it but the entry is still there. My team leader would like me to get rid of the entry before we send the project to translation. Thanks.

Dang, I saw that same problem occur with a project I was trying to fix but eventually I had to start over on a fresh copy of the broken project and did not create the problem again.
If you are using an agency that translates and uses RoboHelp, the last thing I would have done is delete the snippet. They would have translated that once instead of everywhere it is used thus keeping costs down. That is an aside though.
Do you have a backup of the project so that you can recreate the Snippet in the hope that the project is good with that in and you can then delete again to check you used the right option?

What datatype should i use to store imaq image in sql database?

Hi there i am thinking of saving the imaq image into database for retrieval in my website so that it's like a stream but i don't like what datatype does labview store the image as.

You have two options for storing images in a relational database:
A. Don't put it in a database. Store it as a file, and store the pointer int he DB (as mentioned above).
B. Store it as a blob datatype. See here for more info.

Copy the database for my use. my level is beginner

hello, there is a Database here at work
and i was given the permission by the dba to copy and put it in my local drive. i know this is a big one so it might not be possible.
the reason is so i can create my application from maybe home without logging in the real databse.
any ideas on how i can achieve this task?
thanks

Hi ,
After installing the db software and configuring the starter database (using Data Base Configuration Assistant)- which can be done automatically , i advise you to do this way - the dba of your company can export the database schema(s) you work on or need and afterwards you can use this exported file to import it in your pc.....
or he can provide you a sql script which contains all schema objects(tables,views....e.t.c.).

How to store photo images in a database table?

Hello Y'all,
How do I store about 695 signs inventory photo images from a PDF file to an Oracle database table? We are using Oracle 10.2.0.2. What data type should I use for these images? How about the table space? What table space should I allocate to ensure there is no space issue?
Thanks in advance for any/all the help.

Here you go..
Assuming you have a table
test_blob (col1 BLOB);
Create an oracle directory or use an existing one to place the image on the oracle server.
create or replace directory tmp_blob as '/tmp';This tmp location should exist on your server where oracle is installed.
also ftp the image file (say image1.bmp) to this location
declare
l_blob BLOB;
l_bfle BFILE;
l_re BOOLEAN := FALSE;
Begin
DBMS_LOB.createtemporary(l_blob, TRUE);
insert into test_blob(col1) values (EMPTY_BLOB())
returning col1 into l_blob;
--return image into l_blob;
l_bfile := BFILENAME('TMP_BLOB','image1.bmp');
--check if file exists
l_ret := DBMS_LOB.fileexists (l_bfile) = 1;
if (l_ret)
then
DBMS_LOB.fileopen(l_bfile);
DBMS_LOB.loadfromfile(l_blob, l_bfile, DBMS_LOB.getlength(l_bfile));
commit;
else
DBMS_OUTPUT.put_line('File not present');
end if;
end;
/ not tested this exact one.. check for the syntax errors if any.. this should work

How to parse XML and store the data in tables using sql or plsql?

I want to parse the xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xmlListWrapper>
    <size>2</size>
<AppTypeID>10</AppTypeID>
</xmlListWrapper>
and store in a table
|pk|apptypeid|
1     10

You can extract data from your XML along these lines...
SQL> ed
Wrote file afiedt.buf
1 with t as (select xmltype('<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
2 <xmlListWrapper>
3    <size>2</size>
4    <AppTypeID>10</AppTypeID>
5    <AppTypeID>20</AppTypeID>
6 </xmlListWrapper>') as xml from dual)
7 --
8 -- end of example data
9 --
10 select x.*
11 from   t
12        ,xmltable('/xmlListWrapper/AppTypeID'
13                  passing t.xml
14                  columns pk for ordinality
15                         ,apptypeid number path '.'
16*                ) x

        PK APPTYPEID
         1         10
         2         20

Inserting it to a table is obviously achieved using an INSERT ... SELECT ... where the SELECT is extracting the data from the XML.

E-Business Suite Customisations - which version of the Database can I use?

Hi,
We've made some customisations to the E-Business suite and want to find out what the Oracle official line is on licencing database. We think that making the customisations means that we need more database but could a lower (& cheaper) type of database license be acquired (standard?) to handle the processing for any customs and then, using a link, just load the finished data into the Apps interface, thereby avoiding any customs in the Apps db? If so, can it be on the same server as the Apps?

The best place for such app specific request would be in one of the eBusiness forums.
Nicolas.
