DBMS_LOB.WRITE fails to write multi-byte data
We have Oracle 8.1.6 database, UTF8, and a table with a CLOB column. I'm trying to write some multi-byte data (Japanese) to that CLOB using DBMS_LOB.WRITE(lob_loc,48,1,v_buffer);
I get ORA-00600: internal error code, arguments: [711], [25806920], [koklt2u buf], [], [], [], [], []
The data I'm trying to insert is UTF8 encoded(because I selected it from another table in the same database).
Do I need to convert it to a multi-byte fixed width Unicode encoding to store in CLOB? I thought this would happen automatically.
The DBMS_LOB.WRITE seemed worked OK when I wrote extended ASCII chars to the CLOB, but doesn't work for Japanese.
null
I think this is related to Bug 745585 - If the database char character set is varying-width, and you call DBMS_LOB.WRITE() with an input amount that is greater than the data in the buffer, you will get an internal error. The workaround is to provide the correct amount of data in the buffer.

Problem printing simplified Chinese on PM4i printer using multi-byte data
I am new to printing data in Simplified Chinese and have tried for a period of time to get it to work but it is not working. I would appreciate any help.
This is what I have:
1. Chinese data stored as multi-byte data in oracle 10g db. It is in one of the attribute fields on the mtl_system_items table. The data field it is stored in is defined as varchar2(240). I have to extract that data and print it out as simplified Chinese characters on 3x4 label stock on PM4i printer which is setup to use IPL as the default language.
2. Purchased the simplified Chinese font kit ( compact flash card ) and plugged it into the compact flash port on back of the printer. The simplified Chinese font is assigned.
3. Created simple program to build the label file to send to the printer to print the Chinese glyphs. I expected 3 to print but it only prints 1 Chinese glyph and that is not the correct.
a. Data shown in Chinese

b. Data in hex format => E4BCA0E6849FE599A8
c. Data in utf8 => ä¼ æ„Ÿå™¨

i think the issue here may be with formating the mulit-byte data into format it can be printed using the c60 font. Any

I am querying a view in sqlserver 2000 via an odbc database link.
When I query a 26 character wide column in the view in sql developer, it will only return up to 13 characters of the data.
When I query the exact same view in the exact same sql server database from the extact same oracle database using the exact same odbc database link using sql navigator, I get the full 26 characters worth of data.
It also works just fine from the sql command line tool from 10g express.
Apparently, sql developer is confused about how to handle multi-byte data. If you ask it the length of the data in the column, it will tell you 26, but it will only show you 13.
I have found a VERY PAINFUL work around, to do a cast(column_name as varchar2(26) when I query it. But I've got hundreds of views and queries...In all other respects, the settings I have appear to be working correctly.
I can enter multi-byte characters into the sql worksheet to create a package, save it, and re-open the package with the multi-byte characters still visible.
I'm using a fallback directory for my jdk with the correct font installed, so I can see and edit multi-byte data in the data grids.
In this case, I noticed the problem on a column that only contains the standard ascii letters and digits.
Environment->Encoding = UTF-16
All the fonts are set to a font that properly displays western and ge'ez characters. The font has been in use for years, and is working correctly in all other circumstances.
The Database->NLS Parameters tab under sql developer preferences shows:
language: American
territory : American
sort: binary
comp: binary
length: char (I've also tried byte)
If there are other settings that you think might be relevant, please let me know.
I've done some more testing. I created an oracle table with a single column and did an insert into ... select from statement across the database link. The correct, full-length data appeared in the oracle table.
So, it's not a matter of whether the data is being returned or not, it is. It is simply not being displayed correctly. It appears that sql developer is making some unwarranted decisions about the datatable across the database link when it decides to display the data, because sql plus and sql navigator have no such issues.
This is really a very serious problem, because if I cannot trust the data the tool shows me, I cannot trust the tool.
It is also an invitation to make an error based upon the erroneous data display. -
I have the working code to write the byte[] to the OutputStream, and it works
ServletOutputStream out = null;
BufferedInputStream in = null;
try {
byte[] bytes = new byte[1024];
raf = new RandomAccessFile(restoreZipFile, "r");
raf.seek(10);
raf.readFully(bytes);
out = resp.getOutputStream();
in = new BufferedInputStream(new ByteArrayInputStream(bytes));
int data;
while ((data = in.read()) != -1) {
out.write(data);
out.write(bytes);
out.close();
in.close();
catch (Exception e) {
log.error("Failed to write.", e);
}Then, I thought about it. I think it was silly to use the BufferedInputStream again snice the RandomAccessFile already reads to byte[]. Therefore, I skipped the BufferedInputStream and it works. Please correct me if I skipped the BufferedInputStream is a bad idea, thank!
ServletOutputStream out = null;
try {
byte[] bytes = new byte[1024];
raf = new RandomAccessFile(restoreZipFile, "r");
raf.seek(10);
raf.readFully(bytes);
out = resp.getOutputStream();
out.write(bytes);
out.close();
catch (Exception e) {
log.error("Failed to write.", e);
return false;
}Your first code sample writes the data out twice, right?
//once:
in = new BufferedInputStream(new ByteArrayInputStream(bytes));
int data;
while ((data = in.read()) != -1) {
out.write(data);
//twice:
out.write(bytes);And yes, the second way is simpler. -
Hi Experts,
I found very good how-to guide in SDN to read multi records with cobol copybook.
And I would like to write multi records txt file? Every line has different length but fixed. I can have repetitif line like contact because vendor can have several contact but all contacts have the same fixed length.
Exemple Vendor
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Contact:<Moble Telephone>...
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Contact:<Moble Telephone>...
Thanxs,
Nl
Edited by: User NL on Sep 10, 2009 4:51 PMReading yes, writing no.
There are workarounds, e.g. write one file with all header rows, another with all detail rows and both files have the header plus a number in the first two fields, e.g.
HEADER
ORDER;1;data
00001;1;abc
00002;1;def
00003;1;ghi
DETAIL
ORDER;2;LINE;data
00001;2;0001;xyz
00001;2;0002;sge
00001;2;0003;dff
00002;2;0001;rfew
When you then take both files, merge them together and sort them you get them interleaved
00001;1;abc
00001;2;0001;xyz
00001;2;0002;sge
00001;2;0003;dff
00002;1;def
00002;2;0001;rfew
00003;1;ghi
This is just one approach, other work similar. The only multi-record format DS can write out of the box is XML. -

Most efficient way to write 4 bytes at the start of any file.
Quick question: I want to write 4 bytes at the start of a file without overriding the current bytes in the file. E.g. push bytes 0-4 along... Is my only option writing the bytes into a new file then writing the rest of the file after? RAF is so close but overrides :(.
Thanks MelI revised the code to use a max of 8MB buffers for both the nio and stdio copies...
Looks like NIO is a pretty clear winner... but your milage may vary, lots... you'd need to test this 100's of times, and normalize, to get any "real" metrics... and I for one couldn't be bothered... it's one of those things that's "fast enough"... 7 seconds to copy a 250 MB file to/from the same physical disk is pretty-effin-awesome really, isn't it? ... looks like Vista must be one of those O/S's (mentioned in the API doco) which can channel from a-to-b without going through the VM.
... and BTW, it took the program which produced this file 11,416 millis to write it (from an int-array (i.e. all in memory)).

Steve HurstHello Steve,
Firstly, you cannot install Outlook with Exchange because they share certain dll files.
About the EMS question, I suggest we try rebuilding the powershell virtual directory. If it still does not work, check the application log for more referernce.

Write / store xml data in Xe and retrieve stored data using pl/sql
Hi to all,
i'm searching a tutorial on:
A - how to write / store xml data in Xe and retrieve stored data using pl/sql
I don't want to use other technologies, because i use htmldb and my best practice is with pl/sql.
I was reading an ebook (quite old maybe) however it's about oracle 9 and it's talking about xmltype:
1 - I don't understand if this is a user type (clob/varchar) or it's integrated in Oracle 9 however i will read it (it's chapter 3 titled Using Oracle xmldb).
Please dont'reply here: i would be glad if someone can suggest me a good tutorial / pdf to achieve task A in Oracle XE.
ThanxThank you very much Carl,
However my fault is that i've not tried to create the table via sql plus.
Infact i was wrong thinking that oracle sql developer allows me to create an xmltype column via the create table tool.
however with a ddl script like the following the table was created successfully.
create table example1
keyvalue varchar2(10) primary key,
xmlcolumn xmltype
Thank you very much for your link.

How to write non-XML data to a file using an OSB FTP Routing?
Hi --
Situation ... I need to write non-XML data to a file using FTP. A proxy service retrieves XML and transforms it with XSLT to CSV format, then gives it to a Biz service to file it out, using FTP. Simple.
Problem ... OSB sends the contents of $body to any service it calls. Because $body is a SOAP document, it has to contain XML. So therefore I have to put my CSV data into an XML element, in order to put it into $body; and this inner element then gets written to the file, which I don’t want. But if I don't enclose my CSV content in a tag, I get "Unexpected CDATA encountered" trying to assign it to a variable.
There has to be away around this!
Thanks for your help.
John TaylorSolved. Steps:
-- Transform the XML to CSV using an XSL transform. Put the CSV data inside enclosing XML elements, and use a Replace action to put the XML element + CSV contents back into *$body*.
-- Define an MFL transform that only knows about the enclosing XML elements. Use a delimiter of "\n" (hard return).
-- Route from the proxy service to a Biz service that has Service Type = Messaging Service and Request Message Type = MFL; specify the MFL transform, which will receive the incoming *$body* variable, strip off the enclosing XML element within it, and pass the CSV contents to the FTP service.

Hi guys,
I’m new to Mac and have a MacBook Pro Lion OS (10.6.8 I think !!!) with Parallels 7 (Windows 7) installed. Can someone please tell me what is the best software program that I can use to read, write and modify data / files on external HD (NTFS format) from the Mac OS ? I heard of Paragon and Tuxera NTFS. Are they free ? Are they good ? Are there any other software programs out there ? I heard that some people have issues with Paragon.
Thanks.Your best bet would be to take the drive to the oldest/compatible with that drive Windows PC and grab the files off, right click and format it exFAT (XP users can download exFAT from Microsoft) and then put the files back on.
Mac's can read and write all Windows files formats except write to NTFS (and in some cases not read) so if you can change the format of the drive to exFAT (all data has to be remove first) then you will have a drive that doesn't require paid third party NTFS software (a license fee goes to Microsoft) for updates.
Also it's one less hassle to deal with too.

How to Write Waveform graph data to Text File with user option to do so
So, I'm new to labview and am having trouble writing one program in particular. I have a waveform graph that runs for 120 seconds generating a sine curve. I am, however, having a difficult time getting the program to write the x and y coordinates into a text file. I have attached what I have so far.
The first task I was assigned was to write a program that creates a snusoidal curve on the front pannel adding one data point each half second for 120 seconds. The plot should only start when the user presses a start button.
The next part involves giving the user an option to write the generated data to a spreadsheet file called "sine.txt". The file name and location should be hardcoded. The file should contain the x and y coordinates of each data point in columns separated by tabs, also known as delimited.
I have spent several hours tweaking the attached program and I just can't seem to get it to work right. Any suggestions would help at this point.
Sincerely,
A frustrated chemistry student whose research mentor is out of town

Everything else you are doing is just too complicated or a Rube Goldberg.

RodgerWith Java you cannot write to a specific memory location. Java does not have pointers. If you really want to do it, you need to use JNI, i.e write the required functions in C (or other languages that support pointers) and make those functions available to Java (through JNI). This approach is not portable. You can have a look at http://java.sun.com/docs/books/tutorial/native1.1/index.html
