Oracle BLOB insertion

I am getting a runtime NoClassDefFound error while I am trying to get a handle on the BLOB field (after the insertion of an EMPTY_BLOB()).
The sequence of events (using Java code) are:
1. Insert data for the table along with Empty_Blob() for the particular Blob field
2. Select * from table
3. Assign a (OracleResultSet)ResultSet.getBLOB()
At step 3 where the casting occurs, the runtime error is ORACLE_HOME/jdbc/driver/OracleResultSet()
NoClassDefFound
null

I tried inserting using the following code and it worked in single stepOnly if your Data is not longer then 4000 Bytes (or 32K if you do the same in PL/SQL). Otherwise you have to use empty_blob.

Oracle BLOB insert problem

I'm getting a ClassCastException when I try to the blob I get from my CallableStatment. I've seen alot of post about similar issues with oracle 9 and inserting blobs but I havn't found a solution..
Here is the few lines that Im doing..
When I check to see what type of instance this blob is this is what I get in my debugger oracle.sql.BLOB@71d768
so When I ((BLOB)blob).getBinaryOutputStream() I get the ClassCastException..
I've tried to get the innermost delegate and a number of other things.. When I try to cast anything to the Oracle type I get the ClassCastException. When i do an instanceof on the blob it isn't an oracle Blob.. So why does the debugger and getClass().getName() tell me it is.. And is the any work around for this..
Thanks

cstmt.registerOutParameter(6, OracleTypes.BLOB);
             cstmt.execute();
             Blob blob = cstmt.getBlob(6);
                       if(blob != null) {
                     writer = new ObjectOutputStream( ((BLOB)blob).getBinaryOutputStream());
                    if (writer != null) {
                    writer.writeObject(bean);
                      writer.flush();

                 con.commit();

Yes, I modified some code that a collegue used in a standalone application.. His solution was using a CLOB.. I just modified my solution to use a CLOB instead of a BLOB(saving a bean as xml instead of the bean object)..
So i litterally copied his code line for line.. And Im getting the same error. My app is running in tomcat whereas my collegue is using it in a standalon application. I just went thru all lib directories to make sure I only have one copy of the oracle ojdbc14.jar which is in the conf/lib directory of the tomcat server..
I even moved my table from our oracle9 db to our oracle 10 db and still no luck..
String beanToXml = xstream.toXML(bean);
cstmt.execute();
oracle.sql.CLOB clob = ((OracleCallableStatement) cstmt).getCLOB(6)
             if (clob != null) {
                 writer = ((CLOB) clob).getCharacterOutputStream();
                 if (writer != null) {
                   writer.write(beanToXml.toCharArray());
                   writer.flush();
                   writer.close();

Oracle error ORA-01461when trying to insert into an ORACLE BLOB field

I am getting Oracle error ‘ORA-01461: can bind a LONG value only for insert into a LONG column' when trying to insert into an ORACLE BLOB field. The error occurs when trying to insert a large BLOB (JPG), but does not occur when inserting a small (<1K) picture BLOB.(JPG). Any ideas?
BTW, when using a SQL Server datasource using the same code.... everything works with no problems.
ORACLE version is 11.2.0.1
The ORACLE datasource is JDBC using Oracle's JDBC driver ojdbc6.jar v11.2.0.1 (I also have tried ojdbc5.jar v11.2.0.1; ojdbc5.jar v11.2.0.4; and ojdbc6.jar v11.2.0.4 with the same error result.)
Here is my code:
<cfset file_mime = Lcase(Right(postedXMLRoot.objname.XmlText, 3))>
<cfif file_mime EQ 'jpg'><cfset file_mime = 'jpeg'></cfif>
<cfset file_mime = 'data:image/' & file_mime & ';base64,'>

Can't you use "alter index <shema.spatial_index_name> rebuild ONLINE" ? Thanks. I could switch to "rebuild ONLINE" and see if that helps. Are there any potential adverse effects going forward, e.g. significantly longer rebuild than not using the ONLINE keyword, etc? Also wondering if spatial index operations (index type = DOMAIN) obey all the typical things you'd expect with "regular" indexes, e.g. B-TREE, etc.

BLOB insert behavior with thin driver using standard JDBC2.0 and ORACLE-JDBC2.0API

We have a problem with a BLOB insert to an oracle 8.1.7 DB using Oracle 8.1.7 JDBC thin driver.We get socket read/write error after inserting 32k of data using the standard JDBC2.0 API but using the Oracle JDBC2.0API (using OracleResultSet) it goes fine. We have a requirement to use the standard JDBC2.0 so that our code works with multiple database vendors. Is there another way to get in the blob data with standard JDBC API & using thin driver...?

Thanks for the response.
I understand what you are saying...
that readers don't block writers in Oracle (the same is true in SQL Server 2000).
However, I don't see how my test case is working correctly with Oracle (the exact same code acting as I'm thinking it should with SQL Server, but I still think it is acting incorrectly with Oracle).
I have transaction A do this:
update <table> set <column2>=<value> where <column1>='1'
then I use Thread.sleep() to make that program hang around for a few minutes.
Meanwhile I sneak off and start another program which begins transaction B. I have transaction B do this:
select * from <table> where <column1>='1'
and the read works immediately (no blocking... just as you have said) however, transaction A is still sleeping, it has not called commit() or rollback() yet.
So what if transaction A were to call rollback(), the value read by transaction B would be incorrect wouldn't it ?
Both A and B use setAutoCommit(false) to start their transactions, and then call setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED).
Isn't that supposed to guarantee that a reader can only read what is committed ?
And if a row is in "flux"... in the process of having one or more values changed, then the database cannot say what the value will be ?
I can almost see what you are saying.
In letting the reader have what it wants without making it wait, I suppose it could be said that Oracle is holding true to the "only let committed data be read"
So if that's it, then what if I want the blocking ?
I want an entire row to be locked until whoever it in the middle of updating, adding, or removing it has finished.
Do you know if that can be done with Oracle ? And how ?
Thanks again for helping me.

BLOB insertion in Oracle 10g database using ojdbc14 (10g drivers)

Hello!
I have a situation where I am trying to insert a blob data into oracle 10g database using oracle thin
10g drivers, ojdbc14.jar in weblogic 8.1 sp2. I have the following error happening very intermittently.
java.sql.SQLException: OALL8 is in an inconsistent state.
And this is leading to the "No more data to read from socket" error when I am trying to
insert the BLOB into the database. I have gone through the bug list of SP2 and have realised there is the
following issue fixed in SP3.
CR124933
An Oracle BLOB sometimes used a pooled connection after the connection pool determined that
the connection was available for reassignment.
Code was added to ensure the BLOB is completely processed before closing the pool connection or
ending the transaction.
I believe the problem arises when we try to insert BLOB into database using a refreshed connection
from the pool.We have upgraded weblogic 8.1 from SP2 to SP4 service pack inorder to come over the above problem.
But this still continues to behave intermittently.
We put ojdbc14.jar in our classpath and Weblogic startup classpath looks like the following :-
WLS_CLASSPATH=${WLS_DOMAIN_DIR}/appslib/server.jar:$PRE_CLASSPATH:${WLS_WEBLOGIC_HOME}/server/lib/weblogic.jar:
${WLS_WEBLOGIC_HOME}/server/lib/ojdbc14.jar:${WLS_WEBLOGIC_HOME}/server/lib:${WLS_JAVA_HOME}/lib/tools.jar:
${WLS_JAVA_HOME}/jre/lib/rt.jar:${WLS_WEBLOGIC_HOME}/server/lib/webservices.jar:${WLS_CONFIG_DIR}:
${WLS_CUSTLIB_DIR}:${WLS_BIN_DIR}:$POST_CLASSPATH
export WLS_CLASSPATH
CLASSPATH=${WLS_CLASSPATH}:${APP_CLASSPATH}
export CLASSPATH
After upgrade to SP4, there are new ojdbc14_g.jar(debug jar) and orai18n.jar jars in the ${WLS_WEBLOGIC_HOME}/server/ext/jdbc/oracle/10g directory added.
Please let me know if I need to update classpath with the new 10g jars in the ext/lib directory or any suggestions
to insert BLOB using the ojdbc14 10G drivers, Weblogic 8.1 environment would be appreciated.
Following is the stack trace of the errors that I recieve:

PDF binary variable won't save in Oracle blob

I am reading in a small, legitimate PDF as a binary variable and them immediately saving that variable into a blob. But the blob doesn't store the data.
<cffile action="readbinary" file="C:\Test_Files\test.pdf" variable="testdoc">
now shows isbinary(testdoc) = YES
In fact, I can output to the screen using cfcontent, and it displays fine.
But if I try to save the testdoc variable to an Oracle blob, CF seems to think it is trying to insert an empty variable.
<cfquery name="ins" datasource="#request.a_datasource#">
INSERT
INTO PROD_WCT.T_DOCS (
PDF_BLOB
VALUES (
<cfqueryparam value="#testdoc#" cfsqltype="CF_SQL_BLOB">
Now if I retrieve that row (query name=”get_pdf”) and check the value, it appears empty:
now shows isbinary(get_pdf.pdf_blob) = NO
Nothing is done in betweent the cffile and the insert. Any ideas?

Just an update here to note that this problem has not yet been resolved.
This could be in incompatibility between Oracle 10g BLOBs and Coldfusion 8.
To review, my BLOB setting in CFADMIN is enabled. To make this as simple and possible, I created a PDF from the words "Test text," so the PDF document can't get much smaller. The PDF does save to the BLOB, because in TOAD I can save the BLOB contents to a file and view it as a PDF just fine. It's when I retrieve the record in CF8 where the trouble arises. Coldfusion 8 doesn't get anything from the BLOB. It has a zero length, and isbinary = NO. We are using Oracle 10g. And using CF8. My understanding is that an Oracle blob uses pointers to locate the blob data in an area external to the database. Apparently, Coldfusion cannot retrieve the data. The process worked for the first few records when retrieving a blob and displaying it with cfcontent, but after a few records it can no longer retrieve the subsequent blob records. It just abruptly fails at that point. But again, the PDF binary data is there in TOAD.
Could this be a bug or incompatibility with Oracle 10g? We are a state government, and it sure would help if the Adobe people could give come help here.
Thanks in advance for any thoughts.

Oracle & BLOB/LONG RAW

Hi everybody,
I need to store binary data (> 32K) in an oracle BLOB field, respectivly commit the data to an oracle PL/SQL stored procedure.
First I tried to use LONG RAW, but failed to commit more than 32K of data. This seems to be a documented problem, you can store 2GBs in an LONG RAW field, but PL/SQL can only store 32K in an LONG RAW variable.
Then I tried to switch from LONG RAW to BLOB (both the field in the table and the in variable in the stored procedure) but it seems to be very complicated to use BLOB fields with JDBC.
I've found example for a plain INSERT. First execute an INSERT with an empty BLOB, then make an SELECT FOR UPDATE on the row, obtain the reference to the BLOB-Object, alter the BLOB-Object and create an UPDATE-Statement with it.
I've not tried this yet, but according to various web sites it should work.
The problem is, that it does not solves the problem how to commit a BLOB value to a PL/SQL stored procedure.
Does anyone knows a solution?
Thx and regards,
Robert

Hi,
thx for your answer.
That's the solution I described (INSERT, SELECT, UPDATE) and only works with Statements.
But I think I've already found a mistake of mine, I have to try this today.
I already succeeded in creating a BLOB-Object without obtaining it from a resultset, the constructor is not documented but it exists, it looks like BLOB( OracleConnection, byte[] ).
I think I can commit the BLOB to the stored procedure but it won't be a valid BLOB locator.
What I've not tried yet and what I think migth be the solution is creating the valid BLOB locator inside the stored procedure using the PL/SQL BLOB methods.
Sounds simple but for some reasons I have not thougth about it yet. :-)
I'll report the result here if somebody else is interested in the issue. :o)
Thx and regards,
Robert

JDBC Receiver Adapter and Oracle BLOB

Hi,
I would like to put some raw data into an ORACLE BLOB using XI. My idea was to put the data in an xml element, but the JDBC sender adapter doesn't seem to be able to cope with writing. Has anybody gathered experiences regarding this topic?
Kind regards,

It fails because the locater to the blob, obtained by findBYPrimaryKeyis

i.e. an empty_blob() is not created.
Have you got CMP to access Blobs in WLS 6.1?

Sending image from MS SQL SERVER to Oracle BLOB

Hey all, we're trying update Oracle via a SQL Server linked server and we're having an issue with a blob column. The update from SQL is:
UPDATE Banner..GENERAL.PS_EBI_IF_TBL
set photo = a.blob_file, photo_change_date=a.blob_date
from PWNT.dbo.BLOBS a, PWNT.dbo.BADGE_V b
where a.ID = b.ID
and base_name = b.BADGE_BASE_NAME
and b.BADGE_blob_date > getdate()-.021
GO
The error we get is:
OLE DB provider "OraOLEDB.Oracle" for linked server "Banner" returned message "ORA-01747: invalid user.table.column, table.column, or column specification".
The syntax is correct, we can run it if the column being updated (photo) is not a blob, so we believe there is something else we have to do because of the blob. Has anybody done anything like this and know how it works? Thanks!
Tom

Given that there are no version numbers is your post I can imagine many possibilities for misconfiguration. Especially as an Oracle BLOB bears no direct size relationship to anything MS SQL could possibly support.

Oracle BLOB value to a LC variable

Hello,
Is it possible in LC ES2 to coerce oracle blob value to some livecycle variable ?
When mapping sql query result (column of type BLOB) to a LC variable (of type Document), we receive:
com.adobe.workflow.datatype.InvalidCoercionException: Cannot coerce object: oracle.sql.BLOB@27e7d6 of type: oracle.sql.BLOB to type: com.adobe.idp.Document
We have tried mapping to string, binary, Document (, we even desperately hardcoded sql.oracle.BLOB to process XML), but none of this works.
Is it possible to solve this other way, then following ?
http://groups.google.com/group/livecycle/browse_thread/thread/6c4b9156b52b71a7
Thanks.

My idea is to fetch the BLOB column data as UTF8 (base64) encoded string and then use getDocumentFromBase64 available in ES2.
I am not sure what syntax is to fetch from ORACLE.
I have used MySql database and the query is:
SELECT CONVERT(Blob_Column USING UTF8) as MyBlobDataAsBase64Str FROM myTableName;
Now using SetValue activity to look like: myXMLvariable = getDocumentFromBase64(strVariableHoldingBase64Data)
This case works perfectly without any issues.
The problems is you should find out the appropriate syntax for ORACLE.
I was searching about CONVERT() & UNISTR() functions. But i'm unable to evaluate.
Try by yourself..

Store pdf in oracle BLOB hibernate

I need to store PDF files in the oracle BLOB using hibernate. I am using the below code and getting a null pointer. Any thoughts?
Blob blob=null;
byte [] bFile = (byte[])objVal;
blob.setBytes(0,bFile); //null pointer here...
logger.info("EventsDAO- insertDetails- else:--"+((byte[])objVal)+"---blob----"+blob);
hmForm.put(objKey,blob); Thanks in advance.

Samples? Are you asking how to make a blob? I have my doubts about the wisdom of using Hibernate if you can't diagnose a NPE unless that was just momentary code snow-blindness, but whatever, it's your problem:
Either call Hibernate.createBlob(InputStream,long) or just map the field as a byte[] and map it to a Blob type.

I cannot display image (read from oracle BLOB field) on browser?
Following is my code, someone can give me an advise?
content.htm:
<html>
<h1>this is a test .</h1>
<hr>
<img src="showcontent.jsp">
</html>showcontent.jsp:
<%@ page import="com.stsc.util.*" %>
<%@ include file="/html/base.jsp" %>
<%
 STDataSet data = new STDataSet();
//get blob field from database
 String sql = "SELECT NR FROM ZWTAB WHERE BZH='liqf004' AND ZJH='001'";
 //get the result from database
 ResultSet rs = data.getResult(sql,dbBase);
 if (rs!=null && rs.next()) {
 Blob myBlob = rs.getBlob("NR");
 response.setContentType("image/jpeg");//
 byte[] ba = myBlob.getBytes(1, (int)myBlob.length());
 response.getOutputStream().write(ba);
 response.getOutputStream().flush();
 // close your result set, statement
 data.close();
%>

Don't use jsp for that, use servlet. because the jsp engine will send a blank lines to outPutStream corresponding to <%@ ...> tags and other contents included in your /html/base.jsp file before sending the image. The result will not be treated as a valid image by the browser.
To test this, type directly showcontent.jsp on your browser, and view it source.

I am having a similiar problem. I have created the image.php file:
<?
$query = "select a.image_file FROM officer_image a, officer_info b where a.officer_id=b.officer_id and b.officer_lname like 'LEDEZ%' ";
$stmt = @OCIParse ($db_conn, $query);
@OCIExecute($stmt, OCI_DEFAULT);
@OCIFetchInto($stmt, $arr, OCI_ASSOC+OCI_RETURN_LOBS);
$result = $arr['BLOB'];
@OCIFreeStatement($stmt);
@OCILogoff($conn);
$im = @imagecreatefromstring ($result);
if (!$im) {
$im = imagecreate(150, 30);
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
imagestring($im, 1, 5, 5, "", $tc);
Header("Content-type: image/jpeg");
Header("Content-Disposition: attachment; filename=filename_".uniqid(time()).".jpg");
imagejpeg($im,'',100);
imagedestroy($im);
?>
And then in the actual search web page:
<?php
 $tname = $_POST['lname'];
 $lname = "{$tname}%";
 $id = "1";
 //$query = "SELECT officer_id, image_file FROM officer_image WHERE ID='.$id.'";
 $query = "select a.image_file FROM officer_image a, officer_info b where a.officer_id=b.officer_id and b.officer_lname like 'LEDEZ%' ";
 //oci_bind_by_name($sql, ":bv", $lname);
 //oci_execute($sql);
 $stid = OCIParse($conn,$query);
 Header("content-type:image/jpeg");
 OCIExecute($stid, OCI_DEFAULT);
 while($succ= OCIFetchInto($stid,$row)) {
 foreach($row as $item) {
 $blob_message = $item->load();
 // Output the image
 //imagejpeg($blob_message);
 echo $blob_message . " " ;
 //echo "<img src="image.php?id='.$blob_message.'" border="0">. $rows['officer_id']."\">\n";
 echo " ";
 // Free up memory
 //imagedestroy($im);
 //while ($row = oci_fetch_assoc($sql))
?>
Can anyone help?

Oracle blobs performance

I am using Oracle Blobs to write 100 KB XML file to the database. I find the time required for writing this file to the database is around 300 ms .
Can anyone suggest performance improvements

Which jdbc driver are you using? Have you looked at the docs for the driver that you are using for performance hints?
Is this a standalone program or is it a J2EE application? If a J2EE application, try the same thing from a standalone app to benchmark against
