BLOB column in separate tablespace in 9i?

Should a BLOB column go in a separate tablespace in Oracle 9i? And if so, then how to do it?

Should a BLOB column go in a separate tablespacein Oracle 9i?
from documentation

TABLESPACE and LOB Index
Best performance for LOBs can be achieved by
specifying storage for LOBs in a tablespace different
from the one used for the table that contains the
LOB. If many different LOBs will be accessed
frequently, it may also be useful to specify a
separate tablespace for each LOB column or attribute
in order to reduce device contention.
The LOB index is an internal structure that is
strongly associated with LOB storage. This implies
that a user may not drop the LOB index and rebuild
it.
Note:
The LOB index cannot be altered.
And if so, then how to do it? You can specify tablespace during table creation:
create test_table (id number not null,
content blob)
tablespace data
lob (content) store as (tablespace lobs);
/pre]
For existing table:
[pre]
alter table test_table move lob (content) store as
(tablespace lobs);
Thanks for the post and the link!! Do you know if Oracle creates the LOB index on its own? From reading the link, that was the impression I had as if that was handled by Oracle.

BLOB column in own tablespace, in partition, in table, tablespace to be moved

Hi All,
First off I am using Oracle Database 11.2.0.2 on AIX 5.3.
We have a table that is partitioned monthly.
In this table there is a partition (LOWER), this lower partition is 1.5TB in size due to a BLOB column called (ATTACHMENT).
The rest of the table is not that big, about 30GB, its the BLOB column that is using up all the space.
The lower partition is in its own default tablespace (DefaultTablespace), the BLOB column in the lower partition is also in its own tablespace(TABLESPACE_LOB) - 1.5TB
I've been asked to free up some space by moving the TABELSPACE_LOB(from the lower partition) to an archive database, confirming the data is there and then removing the lower partition from production.
I don't have enough free space (or time) to do an expdp, I don't think its doable with so much data.
CREATE TABLE tablename
xx                          VARCHAR2(14 BYTE),
xx                          NUMBER(8),
xx         NUMBER,
ATTACHMENT   BLOB,
xx             DATE,
xx             VARCHAR2(100 BYTE),
xx                     INTEGER,
LOB (ATTACHMENT) STORE AS (
TABLESPACE DefaultTablespace
ENABLE      STORAGE IN ROW
NOCOMPRESS
TABLESPACE DefaultTablespace
RESULT_CACHE (MODE DEFAULT)
PARTITION BY RANGE (xx)
PARTITION LOWER VALUES LESS THAN ('xx')
    LOGGING
    COMPRESS BASIC
    TABLESPACE DefaultTablespace
    LOB (ATTACHMENT) STORE AS (
      TABLESPACE TABLESPACE_LOB
      ENABLE      STORAGE IN ROW
...>>
My idea was to take an datapump export of the table excluding the column ATTACHMENT, using external tables.
Then to create the table on the archive database "with" the column ATTACHMENT.
Import the data only, from what I understand if you use a dump file that has too many columns Oracle will handle it, i'm hoping it will work the other way round.
Then on production make the TABLESPACE_LOB read only and move it to the new file system.
This is a bit more complicated than a normal tablespace move due to how the table is split up.
Any advice would be very much appreciated.

If disc space is the problem, would a network mode export/import work for you? I have never tried it with that much data, but theoretically it should work. You could do just a few G at a time.
I see what you are saying, if we use a network link then no redo would be generate on the export, but it would for the import right. But like you said, we could do 100GB per day for the next ten days and that would be very doable I think, it would just take a long time. On the archive database we backup archivelogs every morning so anything generate on the import would be backed up to tape the following morning.
mtefft wrote:
          Does it contain only that partition? Or are there other partitions in there as well? If there are other partitions, what % of the space is used by the partition you are trying to move?
Yep, tablespace_lob only contains the LOWER partition, no other partitions. Just the LOWER partition is taking up 1.5TB.

Can i move blob column one tablespace to another tablespace

When I ruining the following script
ALTER TABLE T_Transaction_Image
MOVE LOB(RCSCOMPRESSED_IMAGE,CAMERA_PHOTO_1,CAMERA_PHOTO_2,NUMBER_PLATE)
STORE AS TABLESPACE IMAGE
I found error
ORA-22853: invalid LOB storage option specification
Here we have more than one column having BLOB data type .
Question
I want to know can i move multiple column in single alter table ?
and how can i move blob column one tablespace to another tablespace
Thanks in advance

What can I do so that this table gets imported correctly?
Also tell me "whether the BLOB is stored in different tablespace than the default tablespace of the user?"
Thanks in advance.

Hello,
U can either
1) create a tablespace with the same name in destination where you are trying to import.
2) get the ddl of the table, modify the tablespace name to reflect the existing tablespace name in destination and run the ddl in the destination database, and run your import command with option ignore=y--> which will ignore all the create errors.

Migrating a table with BLOB column from one db to another

Hello everybody,
I have two databases D1 and D2. Each database contains table T1 (same structure in both databases). T has a BLOB column and is populated in D1. I have to move all the data from T database D1 into T database D2.
D1 and D2 are located on different machines. T in D1 is a huge table (milions of records). What is the best solution to migrate the T data between the 2 databases?
Any help will be appreciated.
Thank you in advance.
daniela

Depending on the version of the database you have, you could use transportable tablespaces.

I can't import a table contains BLOB column from one user to another user.

1) I create two user both have connect role,and each has its own tablespace, DDL:
create user d2zd identified by d2zd default tablespace d2zd quota unlimited on d2zd account unlock;
grant connect to d2zd;
create user d3zd identified by d3zd default tablespace d3zd quota unlimited on d3zd account unlock;
grant connect to d3zd;
2)Then enter oracle as d2zd and create a table contains BLOB column and insert data to the table.
3) export d2zd as follow:
exp d2zd/d2zd file=d2zd.dmp
4) import to d3zd as follow:
imp d3zd/d3zd fromuser=d2zd touser=d3zd file=d2zd.dmp
the question is the table with BOLB colum can't be import,
it says:have no privilege on tablespace d2zd.
How can I import a table contains BLOB column from one user to another user?

Hi - the reason for as our friend already told ist that a blob can be stored outside of the table segment, in another Tablespace, This is for performance reason.
Sou you would need to have Quota on two tablespaces.
the one which holds the table segment the other which holds the blob(segment).

BLOB column says undefined

Hi .
when i create a BLOB column in the table and describe the structure it says undefined. how do i fix that. also if someone can let me know how to update a RTF content from a VB to the BLOB column in the oracle table?? Tons of thanks in advance

You can write a BLOB- VB to Oracle database using ADO function in VB. Search in MSDN for help on BLOB function. They have a ready eg.
Just in case you don't find it.
Here it is:
Just copy paste this in a form with text boxes for all ODBC parameters.
I think you cannot read directly from a BLOB column. Don't forget to initiate a BLOB column like:
/*LOB table for storing files*/
Drop table FileColumn;
Create table FileColumn
( REPQUE_ID NUMBER(10) NOT NULL ,
RepText_blob BLOB default empty_blob()
Storage (initial 50K next 50K pctincrease 0)
tablespace TEST31ORA
lob(RepText_blob) store as
(tablespace ACCOUNT4
Storage (initial 100k next 100k pctincrease 0)
chunk 16k pctversion 10 nocache logging);
/*initialize LOB locator by making it not null, use empty lob, this will
insert the locator value in that column
I did this initialize in create table script, so that I can do the bulk insert
One can do bulk inserts if there are no rows before
insert into FileColumn
values(1, empty_blob()); */

Load JAR from BLOB column?

I have a JAR file that load and works find when I use the loadjava utility, but my software is now being deployed to a server that I don't have remote access to and can't connect remotely to the Oracle database. I need to push out updated JAR files periodically and would like to automate the updates without requiring help from their DBA.
Is it possible to load my JAR into a BLOB column in the database and then have it loaded from that? In my testing it appears that I can do that for a single class, but I'd like to do the entire JAR. I've tried CREATE JAVA ... USING BLOB, but that appears to be expecting a character stream (java source).
My software is on a separate server from the database, so I don't think I can use a BFILE???
We're using Oracle 10g.
Thanks!

Hi
Sure you can do that :)
I have done a CMS Application Archive importer into DBPrism CMS.
Look at the code (importDir function):
http://dbprism.cvs.sourceforge.net/viewvc/dbprism/cms-2.1/src/com/prism/cms/core/Util.java?revision=1.10&view=markup
First you has to iterate on each entry of the JAR using ZipInputStream class, then for each entry you can create a temporary BLOB to process each "create java class using .." SQL operations.
Here a code snipped:
695 BLOB newContent =
696 BLOB.createTemporary(conn, true, BLOB
697 .DURATION_SESSION);
698 OutputStream ow = newContent.setBinaryStream(1L);
699 while ((size = jin.read(buff, 0, buff.length)) > 0)
700 ow.write(buff, 0, size);
701 ow.flush();
702 ow.close();
703 ow = null;
704 cs.setBLOB(1, newContent);
705 cs.setString(2,(isResource) ? "java resource" : "java source");
706 cs.setString(3, classOrResourceName);
707 cs.registerOutParameter(4,Types.VARCHAR);
708 try {
709 cs.executeUpdate();
710 String loadedClass = cs.getString(4);
711 if (!isResource)
712 listOfLoadedClasses.put(loadedClass,classOrResourceName);
713 log.debug(".importDir - OK loading: "+loadedClass);
714 } catch (SQLException s) {
715 log.warn(".importDir - Error loading: "+classOrResourceName,s);
716 } finally {
717 newContent.freeTemporary();
718 }
cs is:
674 cs =
675 (OracleCallableStatement)conn.prepareCall("{ call begin\n" +
676 " update create$java$lob$table set LOB = ?, loadtime=sysdate where name = 'LOADJAVA/LOB/KEY';\n" +
677 " execute immediate 'create or replace '||?||' named \"'||?||'\" using ''LOADJAVA/LOB/KEY''';\n" +
678 " ? := \"NameFromLastDDL\"(0);\n" +
679 " end }");
Hope this help, Marcelo.

Processing OrdImage data into a BLOB column

Hi,
I am importing 30Mb Tiff images into an ordsys.ordimage column within an image table. All is fine with the import part. I now want to populate a blob column in the same table with a jpeg generated from the tiff. I have tried many variations of the .process and .processcopy functions but I'm getting nowhere. Can anyone help?

You will need to tell us more about what "getting nowhere" means. Are you getting errors? Or do you just not know where to begin? I'll assume the latter.
First of all, you definitely want to use the processCopy() method. process() will overwrite your original TIFF image. If you want the JPEG in a separate column, you must use processCopy to keep the original and create a new copy. Does your JPEG image have to be in a BLOB column? Why don't you store this in an ORDImage column as well? If you store it in an ORDImage column, you can use the processCopy method. If you must use a BLOB column, you need to look at the processCopy procedure of the relational interface.
The interMedia Quick Start Guide for the Object Interface (there is also one for the relational interface if you really must use a BLOB column for your JPEG image column), has a good example of using the processCopy method to create a JPEG thumbnail. You can find it here:
http://www.oracle.com/technology/sample_code/products/intermedia/files/quickstart_guides/intermedia_qs_image.pdf
See the section on Creating Thumbnails and Changing Formats.
If you have selected the source image into an ORDImage variable imgSrc, and the destination image into a variable imgDst, the process command to create a similar JPEG image is:
imgSrc.processCopy('fileformat=jfif', imgDst);

ORA-03237 when creating table with BLOB columns on Oracle 9i

I am playing with my new Oracle 9i database. I am trying to copy
tables from my 8.1.6 db. Three tables won't create due to this
new message. The 9i documentation says it's soemthing to do with
freelist groups but my DBA says he hasn't set up any.
The tablespace is one of these newfangled locally managed
tablespaces (predetermined size 8k).
I can create these tables if I change the BLOB column to datatype
VARCHAR2(4000).
I have raised this through the usual channels, but I thought I'd
try this site as well.

How to view PDF files strored in a BLOB column

Hi all,
I want to display a PDF file, stored in a BLOB column, in a form or through a JavaBean.
But the problem is more complicated then that. I do not want to retrieve the PDF file in the application server that show it through a browser.
Actually, I do not want users to get the entire file, I just want them to see it or print it.
I want, in fact, to display a "stream" of bytes through Oracle Forms. Not a file.
This one, sounded to be a good solution, but actually not. When the file was too big (multiple pages), the application was blocked until the entire file was loaded. And when you try to print it, it wasn't printed right. The advantage of this solution is that it is open-source so we can add methods to connect to the DB, retrieve the content of the BLOB column and displays it without downloading the file.
Here is a good solution. Really good, files are loaded quickly, the rendering is really good and the file is printed perfectly (as it was printed from Adobe Acrobat). The disadvantage of this solution is that it is not open-source and is really expansive.
As you can see, both solutions uses PJC.
So any help, any idea to solve my problem will be highly appreciated.
Thanks to all of you,
Amine
PS : I am using F&R 11gR2

Not entirely. At least we came to the conclusion it doesn't make (much) sense to block the save option of PDFs if you want to allow printing them
Anyway; there is of course another possibilty: you could always write your own java bean PDF reader; there are plenty of java PDF libraries available:
Open Source PDF Libraries in Java
The easiest way would be to choose one which can open a PDF from a URL and render it; I would retrieve the image via mod_plsql using WPG_DOCLOAD and simply use the PDF library to render the PDF. No tempfiles anyway, and if you don't implement it there is also no save button.
cheers

Hello,
I am getting the following errors when I am trying to
insert in a BLOB in the oracle 9i database:
java.sql.SQLException: ORA-00604: error occurred
at recursive SQL level 1 ORA-06502: PL/SQL: numeric
or value error ORA-06512: at line 205 ORA-22297:
warning: Open LOBs exist at transaction commit
time
You're doing exactly what the error says, that is committing with an open LOB. Look at the following piece of code: you write in the LOB, you flush it and then commit. There is no closing of the LOB stream before committing.
Try putting the tempBlobOStream.close() instruction before the commit.
// Write the data into the temporary CLOB from the
he byte array
          tempBlobOStream.write(ba);
          // Flush and close the stream
          tempBlobOStream.flush();
nn.commit();
          //Close everything
tempBlobOStream.close();

How to read BLOB column from a table in SQL or PL/SQL

I have table which is having one BLOB data type column . Ihave inserted few rows in that table . Now i want to see wheather BLOB column has been inserted properly or not . How to read that column through SQL or PL/SQL.
Can anyone help me to do this.

You can only manipulate LOBs in PL/SQL because you have to use the DBMS_LOB package.
