Create Oracle BLOB and Pass to Oracle Stored Procedure

Hi All,
I am using Oracle 10g and am dealing with a requirement where I have to upload a file to Oracle Portal from the client's local machine using a JSP.
I am planning to convert the text file to a BLOB and pass it to an Oracle stored procedure which does the rest.
I am unable to create a BLOB object. Can anybody help me with this please.
Is there a better alternative to do it?
Thanks in advance,
Shardul

u can create blob as below...
java.sql.Blob blob=new Blob();
File file=new File(fullPathTo UrFile);
FileInputStream fInSteam = new FileInputStream(file);
BufferedInputStream bInputStream = new BufferedInputStream(fInSteam);
ByteArrayOutputStream bOutputStream = new ByteArrayOutputStream();
int nextByte;
while (( nextByte = bInputStream.read() ) != - 1)
bOutputStream.write(nextByte);
byte[] byteContent = bOutputStream.toByteArray();
blob.setBytes(byte[]);
i think it should work for u...

Creating Fault Handling and Exception in Oracle BPEL

I am following BPELtutorial-Orderbooking.pdf and have successfully reached chapter 6 i.e. Creating Fault Handling and Exception in Oracle BPEL. Everything went fine except this one... i.e. after implementing the Fault Handling and Exception in Oracle BPEL when I execute my process and enter CustId that begins with 0.... the invokeCR generates error message as follows as expected:
<NegativeCredit xmlns="http://services.otn.com">
<part name="payload">
<error xmlns="http://services.otn.com">Bankruptcy Report</error>
</part>
</NegativeCredit>
However, the execution proceeds ahead instead of terminating. The tutorial states that the BPEL process should terminate as the SSN is invalid, can anyone please tell me whats going wrong.. ?

Well not exactly.... but when click on the 'Audit' sheet under BPEL Console for this instance, I can see the following:
invokeCR (faulted)
[2006/03/20 10:35:07] "{http://services.otn.com}NegativeCredit" has been thrown. less
<NegativeCredit xmlns="http://services.otn.com">
<part name="payload">
<error xmlns="http://services.otn.com">Bankruptcy Report</error>
</part>
</NegativeCredit>
The above is exactly what the tutorial states will be the output, so I presumed that the exception must have fired !

Creating remote objects and passing the retrieved data to modules

I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!

Iam passing an array of objects from Java to the C
file. The total size of data that Iam sending is
around 1GB. I have to load this data into the Shared
memory after getting it in my C file. Iam working on
HP-UX (64-bit). Everything works fine for around 400MB
of data. When I try to send around 500MB of data, the
disk utilization becomes 100%, so does my memory
utilization and I get a "Not enough space" when I try
to access shared memory. I have allocated nearly 2.5GB
in my SHMMAX variable. Also, I have around 45GB of
disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?

Parameter length limition passing to java stored procedure! help

hi:
i am working with java stored procedure to do some resource consuming work. i have to pass a long string (varch2) or bytes(log raw) which is larger than 32k which is the limitation
set by oracle.
is there a walk around?
another question:
i have to call java stored procedure from session beans ( weblogic app server) and how can i make sure the code
in session beans and that in java stored procedures to be in
the same transaction?
regards
daniel wang

Hi Daniel,
In answer to your first question: use a CLOB (for the long string)
and a BLOB (for the long raw). Do a search for CLOB and BLOB at the
Technet site:
http://technet.oracle.com
There are lots of resources including documentation and sample code.
In answer to your second question: first, let me say that the J2EE
forum is more suitable for that question (I haven't looked yet, but
you may have posted there as well!). Anyway, you need to set an
appropriate transaction attribute in your "ejb-jar.xml" descriptor
file for your session bean. If you want to make sure that the
session bean and java stored procedure participate in the same
transaction, I suggest using "Required", as in:
<trans-attribute>Required</trans-attribute>
Hope this helps.
Good Luck,
Avi.

Well you are doing almost everything wrong that could be done wrong.
Here is code that works to insert data into your table (the procedure isn't even needed).
declare
p_sl_num NUMBER := 1001;
p_description VARCHAR2(50) := 'Testing Val1';
inval1 test_type1 := test_type1();
inval2 test_type2 := test_type2();
begin
inval1.extend();
inval1(1) := test_object1('testx1', 'testx2', 'testx3');
inval2.extend();
inval2(1) := test_object2('testy1', 'testy2', 'testy3');
INSERT INTO test_object_tpe
sl_num,
description,
main_val1,
main_val2
VALUES
(p_sl_num, p_description, inval1, inval2);
commit;
end;
/See Example 5-15 Referencing a Nested Table Element in Chap 5 Using PL/SQL Collections and Records in the PL/SQL doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm#CJABEBEA
1. You don't even need the procedure since all it does is a simple INSERT into the table which you can do directly (see my code above)
inval1(1).val1 := 'testx1';There is no element one (1) of 'inval1' since you haven't created any elements yet. You need to EXTEND the collection to add an element
inval1.extend();And then there is an empty element but 'inval1' is a container for objects of type 'test_object1' not for scalars like 'val1', 'val2', and 'val3'.
So you can't do
inval1(1).val1 := 'testx1';You have to create an instance of 'test_object1'
inval1(1) := test_object1('testx1', 'testx2', 'testx3');And so on for the other collection
You don't need the procedure (as my sample code shows) but once you populate the variables properly it will work.

How can i create a Global Temporary Table inside a Stored Procedure....

Hi...
I need to create a Global Temporary Table inside a Stored
Procedure....
I have no idea how to do that....
Please....if u can send me a sample, send to me....
Thanks a lot

To create a global temporary table inside a stored procedure,
the minimal syntax would be:
CREATE OR REPLACE PROCEDURE procedure_name
AS
BEGIN
EXECUTE IMMEDIATE 'CREATE GLOBAL TEMPORARY TABLE table_name'
|| '(column_name NUMBER)';
END procedure_name;
As Todd stated, it would probably be better to create the global
temporary table outside of the procedure:
SQL> CREATE GLOBAL TEMPORARY TABLE table_name
2 (column_name NUMBER);
Table created.
You can also specify things like ON COMMIT PRESERVE ROWS or ON
COMMIT DELETE ROWS.
It may be that there is something else, like a PL/SQL table of
records or a cursor, that would suit your needs better. It is
difficult to guess without knowing what you want to do with it.

How Create a Global Temporary Table inside a Stored Procedure?

Hi...
I need to create a Global Temporary Table inside a Stored
Procedure....
I have no idea how to do that....
Please....if u can send me a sample, send to me....
Thanks a lot

there are many ways to do this..
one u can use dbms_utility package to run ddl statements like
for ex:
declare
t varchar2(200):='order_no';
v number;
begin
--dbms_utility.exec_ddl_statement('select '||t||' into '||v||'
from
--ordermaster where rownum=1');
dbms_utility.exec_ddl_statement('create table cvt(t number)');
dbms_output.put_line(v);
end;
but the actual method(recommended) involves a bit coding using
dbms_sql package you will find examples on technet or metalink
to use this package..
I hope this helps

Creating/constructing a java.sql.Blob and writing to Oracle with jdbc

I'm trying to understand how to create a blob from an image file to write it to a Oracle database using jdbc.
I know there'a a getBinaryStream method in java.sql.Blob to which I can write the files byte array, but how do I create an actual blob in the first place. All examples I've seen initialise the blob from an exiting Blob field in a database which I do not have filled yet
thanks

In general, you will do something like the following:
Ensure setAutoCommit is false
INSERT INTO foo (blob_column) values (empty_blob());
SELECT blob_column FROM foo FOR UPDATE;
Call getBlob() on the ResultSet
Cast it to Oracle's specific BLOB (different object)
Call getBinaryOutputStream() on the BLOB
Pipe your data
Commit (very importatnt as FOR UPDATE will lock that row)- Saish

Help required in handling of Oracle BLOB and CLOB in OC4J

Hi,
I am in a process of porting my application from Weblogic 6 to OC4J.
I have problem while handling CLob and Blob's in oracle. Weblogic has
classes defined to do the same. (weblogic.jdbc.common.OracleClob)
Does any one know how I can achieve this.
Thanks in advance.
Regards,
Moin

We have an application running on OC4J accessing an Oracle 8.1.7 db, and have no problems using BLOBs and CLOBs. It is explained quite clearly in the Oracle documentation.
If you require further assistance let me know :-)

Pass BLOB as parameter to Packaged Stored Procedure

Does JDBC (thin or otherwise) support passing a BLOB as a parameter to a packaged stored procedure in Oracle, or do we have to do an 'insert' statement to get it in?
All the articles I've seen seem to refer to insert and select, but I want to strictly enforce all access to the database being through a package rather than table level access.
We've certainly had no difficulty receiving blobs from the resultset returned by our packaged procedures.
Any help appreciated,
Thanks
Jason.

Can someone please demonstrate exactly how to use formula results as date parameters to a SQL stored procedure? Keep in mind, there are two parameters to the stored procedure.
I have gleaned this much: Use Add Command and insert the procedure with
EXEC ServerName.dbo.usp_sprocName;1 '{?StringParameter}'
but if I try to do
{CALL ServerName.dbo.usp_SprocName({@Formula1},{@Formula2})}
then it gives the error "No value given for one or more required parameters".
Both of the parameters are VARCHAR(50).

Oracle 8..How to call stored Procedure to call stored Function

Student here. Using Oracle 8, without Procedure Builder. Only have SQLPlus environment. Three simple code blocks follow:
block One Creates a Function
block Two Creates a Procedure
...However, I do not know how to Start, Run, Get..@ <or whatever command at SQL> prompt, to run the Procedure to call the Function.
block Three is a script that calls the function, but I wish to call the stored procedure (from block Two above). My user manual PL/SQL Intro does not address.
Please provide simple SQL Plus steps, command, path whatever.

PL/SQL procedure successfully completed.

Follow this steps to run the procedure.
1. save the procedure in a folder in your hard disk as NEW_SALARY2.SQL.
2. go to SQL*PLUS and then goto FILE->OPEN
3. Then goto your folder where you have saved your procedure and then click once(only once) on the procedure name and then click cancel.
4. Then type SQL>@NEW_SALARY2.SQL;
it will execute your procedure.
important: if you don't want to do that then
type:
SQL>exec c:\myfolder\NEW_SALARY2.sql
it will execute your procedure.
The same applies for your script.
I hope this will help. If u still need help
