Standard Blob Types- Unsupported feature

Hi There,
I have come across an issue i.e. On attemping to create a Large Object using the Standard Lob Types i.e. java.sql.Blob I get an Exception as shown below:
java.sql.SQLException: Unsupported feature
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269)
at oracle.jdbc.dbaccess.DBError.throwUnsupportedFeatureSqlException(DBEr
ror.java:690)
at oracle.sql.BLOB.setBinaryStream(BLOB.java:1016)
Kindly, note my requirement
Ora thin driver : 9.2.0.5
Must try to only use java.sql.Blob instead of oracle.sq.BLOB
Code must be WAS and WebLogic compatible//oracle.sql.BLOB; works for me
OutputStream blobOutputStream = ((oracle.sql.BLOB) documentAsBlob)
.getBinaryOutputStream();
//java.sql.Blob; does not work ( preferrable-as it makes use of a Standard Type)
OutputStream blobOutputStream = ((java.sql.Blob) documentAsBlob)
.setBinaryStream(0L);
I was wondering how to shoot this.
Any ideas would be appreciated.
Cheers!

JDBC ADPATER - "Unsupported feature" in XI with CLOB type

Hi experts,
I have 15 patch XI level. In a stored procedure i use an in and out parameter with CLOB type. I get the exception:
com.sap.aii.af.ra.ms.api.DeliveryException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'XXXX'): java.sql.SQLException: Unsupported feature
If i change the type CLOB by VARVHAR in the XI's XML (Design: Integration Buider), all works fine.
The strored procedure has this parameter like CLOB.
My question is
Is not possible to use the CLOB type?
SAP recognize that it, it's possible:
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/frameset.htm
Sorry for my english. Thanks in advance.

Hi,
Please make sure you use the 10.x driver for full stored procedure CLOB support.
A CLOB is a not comparable Datatype in SQL.

Blob writing error ORA-29532 Java call terminated Unsupported feature

Hi there,
I've got the following Java code which tries to write to a BLOB file. It's a version of some code to extract files from a zip archive, but with everything but the erroring call stripped out:
create or replace and compile java source named zipunpack as
package org.bristol.cyps;
import oracle.sql.BLOB;
import java.util.zip.*;
public class ZipUnpack
public static int unpack(BLOB ziparray[], String filename, BLOB filearray[])
throws java.sql.SQLException, java.io.IOException
BLOB file = filearray[0];
java.io.OutputStream fileout = file.setBinaryStream(0L);
return 1;
This is published as follows:
create or replace function zip_unpack (
pio_zip in out nocopy blob
, pi_filename in varchar2
, pio_file in out nocopy blob
) return number as language java
name 'org.bristol.cyps.ZipUnpack.unpack(oracle.sql.BLOB[], java.lang.String, oracle.sql.BLOB[]) return java.lang.Integer';
And called like so:
procedure send_zip_file (
pi_zip in out nocopy blob
, pi_filename in varchar2
) is
file blob;
completed integer;
begin
dbms_lob.createtemporary (
lob_loc => file
, cache => false
, dur => dbms_lob.call
completed := zip_unpack(pi_zip, pi_filename, file);
if completed > 0 then
bare_html.print_blob(file);
else
htp.print('File "' || pi_filename || '" not found');
end if;
end;
This, as far as I can tell from the documentation, should work. Unfortunately, though, it generates an error:
ORA-29532: Java call terminated by uncaught Java exception: java.sql.SQLException: Unsupported feature
The particular line which is causing the error is the "java.io.OutputStream fileout = file.setBinaryStream(0L);" If I remove this, it runs fine. I'm flumoxed as to why this might be causing an "Unsupported feature" exception when it's documented as being supported. Can anyone shed any light?
Cheers,
Robert

Hi,
It looks like you are not using 10g JDBC. java.sql.Blob.setBinaryStream is a JDBC 3.0 method. In 9iR2 we added support for jdk14 and added stub methods for JDBC 3.0 behavior without fully implementing them. 10gR1 was the first version where the JDBC3.0 methods were fully supported.
The workaround is to use the Oracle proprietary method oracle.sql.BLOB.getBinaryOutputStream

DatabaseMetaData.getAttributes throwing 'unsupported feature' exception

Hi, maybe someone can help me with this.
For a given schema, I'm trying to find the definition of a user-defined type. However, the getAttributes method of DatabaseMetaData throws an exception, claiming that the feature is unsupported.
This is the code:
Connection connection = null; ResultSet resultSet = null; try { connection = DriverManager.getConnection( URL, USERNAME, PASSWORD ); DatabaseMetaData dbMD = connection.getMetaData(); System.out.printf( "%s %d.%d%n", dbMD.getDatabaseProductName(), dbMD.getDatabaseMajorVersion(), dbMD.getDatabaseMinorVersion() ); resultSet = dbMD.getAttributes( null, null, "BATCH_T", "%" ); // this is line 32 // code to print the ResultSet } finally { if( resultSet != null ) resultSet.close(); if( connection != null ) connection.close(); }
And this is the output:
Oracle 10.2 Exception in thread "main" java.sql.SQLException: Unsupported feature at oracle.jdbc.OracleDatabaseMetaData.getAttributes(OracleDatabaseMetaData.java:10980) at udttest.Main.main(Main.java:32)
The driver is the very latest one from the Oracle site, ojdbc6.jar, version 11.2.0.2.0. According to the JavaDocs of OracleDatabaseMetaData, the getAttributes method has been there since 9.0.2. So does this means that the method has merely been present, and always throws this exception?
Alternatively, is there another way of programmatically retrieve information about a user-defined type?
Thanks,
- Peter

Yes, but the question was not how PL/SQL could know about how a Java object looks like, but how Java can know how a PL/SQL object looks like.You said the following.
+"One issue we have at work is to pass to or receive from a PL/SQL stored procedure a Java object."+
What I read from that is that you wish to get/send a "java object" to PL/SQL.
Thus PL/SQL would in fact need to know what a "java object" is.No, you forgot to read the context: I wanted to know how Java could figure out how an Oracle user-defined type looked like, not the other way around. This business of "PL/SQL knowing about a Java object" is something you invented, that you keep harking on, and which I never said. So could you please drop it?
I read what you posted, not your mind.
Well, I could think of having the business logic for an application in PL/SQL, and using Java to create an API or web > > > Specifically, it's about an SMS sending application, which is interacting with just one table in Oracle and an SMS-C. Want to send an SMS? Insert it into the table. Want to receive one? Read it from the table. Any application that wants to send any number of SMS's, would therefore interact with this database, and a lot of things can be done purely in Oracle, without the need of having a separate application requiring the attention of support staff.Which I can implement completely and easily without using PL/SQL user defined types.Really? There are a lot of optional parameters when sending an SMS. It's not just sender, recipient and text content. So if I want to send, say an identical message to 10,000 recipients, or I want to send 10,000 individual messages; in both cases, with certain parameters for such things like time-outs, SMS-C port, protocol ID, data coding, delivery report options, priority, and all the other things that SMPP allows you to define, how would you pass those in a manner that doesn't lead to dozens of stored procedures, or very long parameter lists?
Standard normal form in relational databases - an option table.
And I doubt a valid format for delivery would work with 10,000 recipients stored in a single UDF verus a receiptant table.
Not to mention of course that the fact that there might be one case for a UDF doesn't mean that the usage is a good idea for most applications. Or even that one application that uses a single UDF will need more than one of them.
Restating what I said "...doesn't mean that it *normally* a good idea to use it."
To clarify your confusion about that statement it means that there will in fact be some cases where it is acceptable but most cases it is not.
Or do you prefer calling stored procedures with endless parameter lists? Or to have a whole bunch of insert and update statements called from Java?No idea what you are talking about. See the above example about sending SMS messages.
Option table.
First what you mention above is a standard idiom in all programming languages and used extensively since interactions between programming languages and relational database began.What, whole loads of stored procedures, or doing all the updates and inserts from Java? We've come to the conclusion that the inability to validate an SQL statement in Java source code is a bugger, and that it's better to do this sort of thing in a stored procedure. Also, using arrays means a significant performance improvement, and an array of objects/user-defined types is the next thing that comes to mind.
That will not be a consideration in most applications. And for those applications where there is a proven performance bottleneck at the database layer most applications would be better served with one or more of the following
1. Redoing the architecture/design
2. Using a caching mechanism.
3. Even look at redoing the requirements.
Secondly I have no idea what you mean by "endles parameter lists". I do not have that problem. If you do then I can only suggest that you should look at problems with your design rather than than attempting to solve it with your implementation.If you have a lot of parameters, like with sending SMS messages, some of which are optional whilst others are not, and when many of these parameters are identical between different insert statements, you have two options:
* use very long parameter lists.
* use user-defined types; for example, an array with 'recipient + messages' types, and a single 'all other options' type.
Or an option table.
Perhaps not, but I didn't take off at a tangent. Anyway, one way of preventing binding is by having one of the frameworks figure out on its own what the other is doing. The whole reflection and annotation thing in Java lets you do that. Unfortunately, the getAttributes() method does not.
First as you yourself noted it is irrelevant.No, that's something you claimed. When you ask for an example, don't brush them off as being irrelevant.
My mistake then.
Second dynamic interface code is NOT a mechanism that reduces coupling. The fact that it is dynamic does not alter the dependency.It reduced coupling between source code, which is what it's all about. I can always fix a library; it's a lot easier than changing dozens of applications.
No it doesn't. Coupling is coupling. The manner of calling the methods doesn't alter the semantics that require that the method is called in the first place.
That is similar to claiming that something like perl/javascript is less "coupled" because the language is interpreted versus C++ where the method calls are compiled. Which of course is not true.
I can store data in a database, any database, in any number of ways. None of which would require a Oracle user defined type.True, but I'm using Oracle for more than just storing data. PL/SQL is extremely powerful for certain operations, and it'd be silly not to employ that power.Which has nothing to do with what I said.Quite frankly, I'm at a loss what point exactly you're trying to make. Passing data between Java and Oracle user-defined types and arrays is a total pain, so as a programmer I'm trying to find a way to do this in a standard way, something that can be put in a library. I agree that it a complex issue.
It however is not something that most applications need however since most do not need UDFs.
And so I have written such a library: small, database-agnostic (should work with any JDBC data source, although I haven't tested it yet), but with annotations to mark what UDT a class maps to, and to what field within the UDT each field of the class maps to. It's the annotation bit I was wondering whether it could be avoided. Obviously, because Oracle doesn't support the getAttributes method, it would no longer be database-agnostic. Which is not really a problem, because we only use Oracle, unless a vendor supports only some other database.
Not sure what that means since most other databases do not support UDFs.
That fact that a feature exists is not by itself a reason to use it. Java has 'strictfp' but I have never had a single business need that required that I use it. As such if I saw someone attempting to use it or stating that it must be used then I would insist that the provide specific details driven from the business needs that required its usage.The fact that you cannot think of a use or a business need, does not mean one does not exist. I suggest you re-read my first post, since that is not what I said.

Can i see the column DATA(BLOB type) in PM_OBJECTS of DCM schema

we installed DCM managed clustering .it is Database repository type.
i am trying to see the column DATA(BLOB type) in PM_OBJECTS of DCM schema .
I wrote a program in java to read blob data type and write it into a temporary file.
when i open temporary files all the data in junk format.
can i see the real data of thatcolumn.Is it possible?
first of all for what purpose DCM shema will be used?

Hi,
There is no option to show the comments on the diagram.
We plan to add such feature in the next version.

Oracle 11gR2 AQ Enqueue from Java - Exception : Unsupported Feature

Hi all,
Can anyone please explain the following error message?
It would appear that OracleConnection.enqueue( queueName, enqopts, mesg ) doesn't work in this configuration....
Is this expected or am I doing something silly? (And if so, what am I doing that is silly?)
(Or is this yet another unexpected face-palm due to Standard Edition?)
Many thanks,

Hi all,
By the way, I do understand that this ability isn't supported in the server-side driver ...( although I am kind of curious as to why )...
If I change the Connection URL to use the jdbc:oracle:thin driver it does work... (can't get the oci driver to work though).
Ah well, regards to all...

Image file stored in a blob type ingest to endeca 3.1 via integrator

Hello All
is it possible to ingest Image file stored in a blob type ingest to endeca 3.1 via integrator?
i tried to load an image using type: byte but getting the following error massage:
Unsupported type "byte" in field "PERSONIMAGE"
i know that in demo's there are images as avatars and other images.
any idea how to approach?
thanks

Hi,
We finnally succeeded. Dsegard gave us the right solution. <div>It was the setup of the display that was on error. We use VNC as the display. Now the display is set correctly and the reports shows up fine.
By seting REPORTS_DEFAULT_DISPLAY=NO, It did work for both the server and the local host.
Thank you dsregard.</div>

Update Blob type field

I don't understand why.... I can't seems to update blob field type. Is there a special type of update for blob type? I will get the value from the form, typecast it to string then update the db. All fields can be updated except the blob type field....

It depends. Eg. Oracle requires to call its own factory classes. You cannot use standard JDBC.
The same with DB2.

Cant schedule refresh - We can't perform this operation because this workbook uses unsupported features. Correlation ID: 42e1a475-20ea-41ae-9d8d-e1889d4c2d77

Hi all,
I have a workbook with a set of scheduled refreshes (powerquery via the gateway from web api). I've modified it by adding a new source from the azure marketplace. I've successfully added it to the DMG
I've uploaded the new report and I'm able to browse it successfully in powerbi

I don't think that's it. I deleted all the powerview reports and worksheets containing pivot tables/charts, and the refresh worked with the function.invoke() call.
The only reason that's in there is because the execution stops there when I dont have it and i have to manually click an 'invoke' button. If there's a way to get around that i'll happily try that instead.
Hmm.. i think I found it, but i'll need to do some testing next year after the holidays to verify
I had added two text boxes (name and desc) to one of my worksheets. I was able to test connection/schedule and run a refresh once I had deleted them.
Weird, because o365 excel services had no problem displaying the worksheet containing the text boxes, but it looks like workbooks that contain text boxes don't work on a scheduled refresh

How to populate custom fields in SAP standard Basic type DELFOR01(E1EDK09)

I've a requirement to include and populate 2 custom fields in SAP standard basic type DELFOR01 and Segment E1EDK09 (it is at hierarchy level 1 ) .
The requirement looks very simple but for this, as per my knowledge, I have to create a new Basic type with the copy of segment E1EDK09 and attach it to outbound process code and write my own function module to populate the segments.
It seems ok but the there are some existing codes in the user-exits for the SAP standard function module.These codes will not get triggered.(Or I've copy the user-exits code in my FM)
Can we do it any other way to handle this kind of situation?
Thanks in advance for your suggestions and help.

Hi Phani,
You have done it correctly. ECC additional data to be moved to EWM, 1. you need to enhance the CIF for master data/ bapi to populate the data in the custom field in EWM. 2. Make your your are not enhancing only one structure. You need to do it in the CI includes so that the field is available in all the related tables/structures.
3. The BAPI/FM which updated these tables will take care automatically to update the custom field data if the field is correctly added in all the tables.
4. If the custom fields are added correctly and still the data is not getting saved , then need to check the mapping of the custom field and bepi extension.
Let me know if this helps.

Download link to file saved in BLOB type in database

Hi all,
I have made a page where i am letting users upload a file in any format, and i'm saving it to database in BLOB datatype field of a table.
The filetype is also saved in a different column of the table.
Now I want to retrieve the contents back in that particular format by converting the data in BLOB type to filetype.
And a link should be provided to download the file.
A little help can be taken from this link which uses EJB session to do the same thing.

How to show BLOB type Column ? In XE

How to show BLOB type Column as image in APEX report area? (In XE)
I did it with the following procedure
create or replace PROCEDURE MY_IMAGE_DISPLAY (p_image_id IN NUMBER)
AS
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc BLOB;
BEGIN
SELECT 'JPEG', MLOGO, 'IMAGE', DBMS_LOB.getlength (MLOGO)
INTO l_mime, lob_loc, l_file_name, l_length
FROM CARS_TABLE
WHERE M_ID = p_image_id;
OWA_UTIL.mime_header (NVL (l_mime, 'application/octet'), FALSE);
HTP.p ('Content-length: ' || l_length);
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (lob_loc);
END my_image_display;
GRANT EXECUTE ON my_image_display TO PUBLIC;
and executed the following command
CREATE PUBLIC SYNONYM my_image_display FOR shema_name.my_image_display;
but under XE , I can not see synonym? why?

sakrami,
Your question really belongs in the XE forum:
Oracle Database Express Edition (XE)
I think this posting addresses your question:

Hi Hoo,
Electronic Data Interchange (or EDI) refers to the use of computers in formatting and exchanging business information using internationally recognized standards and formats. Standards organizations throughout the world have defined hundreds of document types to create a universal language for companies to conduct business while using dissimilar systems and processes. Common business documents, such as the invoice, purchase order, production planning schedule, ship manifest, and customs declaration, have been standardized and are sent and received electronically over private secure networks (Value-Added Networks - VANs) and the Internet.
So EDI is not an SAP product, It is a method to exchange the data over internet.
You dont get any information in any table in SAP. SAP supports EDI to exchange the data over internet. There are no. of third party EDI tools to connect to SAP.
following is link to know more about EDI message types.
