Character sets and ado

I have a table with a clob field on an Oracle 8.1.7.4 database. When querying the clob field via odbc and ado the value is truncated. The Oracle server and client are using a WE8ISO8859P1 character set. Has anyone come across this before.
Thanks.

I believe the data should be able to be represented by IS0-8859. The data is a long random string of characters that represents a fingerprint image.
We seem to only get 996 characters back from the database. If I do a getchunk on the data then I get 996 characters of data, then 996 NULLS, then 996 characters of data and so on. The 996 NULLS should be data.
The data is in the database because I can do a dbms_lob.substr and get the correct info back.

Character sets and conversions

Hi all,
were facing a quite complex problem, for which I'am not even able to specify were it is going wrong or what needs configuring, partly for lack of experience and partly for combining different tecnical areas from which I'm only responible for some of them.
So I'll sketch breefly the situation, and hopefully you might give me some guidelines or hints as to where to look at.
The setup : web application (so clients access by use of browser) on Weblogic- Linux platform, Tuxedo on Iseries , and as far as I understand some DB internally to Iseries where data is stored.
Data is entered in the DB by use of some data-entry application that comes with the iSeries.
The problem: consulting data by use of the web-aplication , some characters dont show up correctly , e.g. @ in email addresses, e's with accents, ...
For the chain being "browser <-> WL <-> Tuxedo <-> DB" , the problem might be different points. But from trace beeing activated , we could see that the response going out of tuxedo to WL is not correct...
Any hint as to what to look for, what can configuration is important, would be welcome ...
Some sub-questions:
- I understand Tuxedo is always "installed" in English , with no other option. This means that f.e. logs are in English.
But can/need to define some character set?
- Between Tuxedo <-> DB you can use som conversion tables ?
Any help would be apreciated , were quite lost ..

Hi,
Given that you are running Tuxedo on iSeries, I'm guessing you are running Tuxedo 6.5 as the port for the current Tuxedo release on iSeries hasn't been released yet. Tuxedo 6.5 does not directly support multi-byte character strings. The two common buffer formats for string data in Tuxedo are STRING which doesn't support multi-byte characters, or CARRAY which does support multi-byte characters as a CARRAY is essentially a blob. Do you know what buffer type the Tuxedo application is using to send data to WebLogic Server?
In Tuxedo 9.0 and later, direct support for multi-byte strings was added in the form of the MBSTRING buffer type. This buffer type supports multi-byte strings with a variety of character sets and encodings.

UTF/Japanese character set and my application

Blankfellaws...
a simple query about the internationalization of an enterprise application..
I have a considerably large application running as 4 layers.. namely..
1) presentation layer - I have a servlet here
2) business layer - I have an EJB container here with EJBs
3) messaging layer - I have either Weblogic JMS here in which case it is an
application server or I will have MQSeries in which case it will be a
different machine all together
4) adapter layer - something like a connector layer with some specific or
rather customized modules which can talk to enterprise repositories
The Database has few messages in UTF format.. and they are Japanese
characters
My requirement : I need thos messages to be picked up from the database by
the business layer and passed on to the client screen which is a web browser
through the presentation layer.
What are the various points to be noted to get this done?
Where and all I need to set the character set and what should be the ideal
character set to be used to support maximum characters?
Are there anything specifically to be done in my application code regarding
this?
Are these just the matter of setting the character sets in the application
servers / web servers / web browsers?
Please enlighten me on these areas as am into something similar to this and
trying to figure out what's wrong in my current application. When the data
comes to the screen through my application, it looks corrupted. But the asme
message when read through a simple servlet, displays them without a problem.
Am confused!!
Thanks in advance
Manesh

Hello Manesh,
For the database I would recommend using UTF-8.
As for the character problems, could you elaborate which version of WebLogic
are you using and what is the nature of the problem.
If your problem is that of displaying the characters from the db and are
using JSP, you could try putting
<%@ page language="java" contentType="text/html; charset=UTF-8"%> on the
first line,
or if a servlet .... response.setContentType("text/html; charset=UTF-8");
Also to automatically select the correct charset by the browser, you will
have to include
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> in the
jsp.
You could replace the "UTF-8" with other charsets you are using.
I hope this helps...
David.

[urgent] oracle character set and national character set !!(dictionary)

Hi. everyone.
What is the oracle dictionary that contains information of
oracle character set and national character set?
I checked v$database, but there was not the information.
It seems that there are some differences between "nls_* " init parameters
and the database character set.
"Alter database backup controlfile to trace" gave me the character set of db,
but I would like to know whether there are oracle dictionary regarding them.
Thanks in advance. Have a nice day.
Best Regards.

I found the dictionary which contains the information of character set and
natiional character set of database.
select * from nls_database_parameters
where parameter like '%CHARACTERSET';
Thanks for reading.
Have a good day.
Best Regards.

Oracle 8.1.5 install on Linux Redhat 6.0: character set (and other) problem(s)

I am trying to install Oracle 8i on Linux and it does not work : once the install is finished, I have a message saying that "Character Set not found".
I am runing a french version of Linux (fr-latin 1) and I try to install Oracle with French and English as languages
An other problem about this install : Oracle does not seem to recognize that I have 6,9 Giga for it to install, and says that I have not enough space for the install...
And at the end of the install, it takes for ages (about 15mns) during which nothing seems to happen. On one machine I got out of this phase, but on the other I never saw it finish, it looks as if the computer crashed. Is that normal?
I went through all the initialization phases, set the correct environment variables...
thanks

I've been dealing with the same problems in the english version but could bypass thiss by doing the folowing.
-Just ignore the disk space stuff
-Ignore the charset message, also
-When creating a database, choose custom and then select the WE8ISO8859P1 char set. It worked for portuguese, must work for french also.
-Everyone here recommended, and I do the same, leave the database creation for later, not during instalation.
Good Luck!

Oracle Database Character set and DRM

Hi,
I see the below context in the Hyperion EPM Installation document.
We need to install only Hyperion DRM and not the entire Hyperion product suite, Do we really have to create the database in one of the uft-8 character set?
Why it is saying that we must create the database this way?
Any help is appreciated.
Oracle Database Creation Considerations:
The database must be created using Unicode Transformation Format UTF-8 encoding
(character set). Oracle supports the following character sets with UTF-8 encoding:
l AL32UTF8 (UTF-8 encoding for ASCII platforms)
l UTF8 (backward-compatible encoding for Oracle)
l UTFE (UTF-8 encoding for EBCDIC platforms)
Note: The UTF-8 character set must be applied to the client and to the Oracle database.
Edited by: 851266 on Apr 11, 2011 12:01 AM

Srini,
Thanks for your reply.
I would assume that the ConvertToClob function would understand the byte order mark for UTF-8 in the blob and not include any parts of it in the clob. The byte order mark for UTF-8 consists of the byte sequence EF BB BF. The last byte BF corresponds to the upside down question mark '¿' in ISO-8859-1. Too me, it seems as if ConvertToClob is not converting correctly.
Am I missing something?
BTW, the database version is 10.2.0.3 on Solaris 10 x86_64
Kind Regards,
Eyðun

Non latin character sets and accented latin character with refind

I need to use refind to deal with strings containing accented
characters like žittâ lísu, but it doesn't seem to
find them. Also when using it with cyrillic characters , it won't
find individual characters, but if I test for [\w] it'll work.
I found a livedocs that says cf uses the Java unicode
standard for characters. Is it possible to use refind with non
latin characters or accented characters or do I have to write my
own Java?

works fine for me using unicode data:
<cfprocessingdirective pageencoding="utf-8">
<cfscript>
t="TÃ¡ mÃ© in ann gloine a ithe;

orm";
s="Ã¡";
writeoutput("search:=#t#<br>for:=#s#<br>found

</cfscript>
what's the encoding for your data?

Conversions between character sets when using exp and imp utilities

I use EE8ISO8859P2 character set on my server,
when exporting database with NLS_LANG not set
then conversion should be done between
EE8ISO8859P2 and US7ASCII charsets, so some
characters not present in US7ASCII should not be
successfully converted.
But when I import such a dump, all characters not
present in US7ASCII charset are imported to the database.
I thought that some characters should be lost when
doing such a conversions, can someone tell me why is it not so?

Not exactly. If the import is done with the same DB character set, then no matter how it has been exported. Conversion (corruption) may happen if the destination DB has a different character set. See this example :

Running instances with different character set WE8MSWIN1252 and AL32UTF8

We have db instances running AL32UTF8 character set and our applications are built around it, however we have request to create instances using WE8MSWIN1252 character set for another application without bringing in new h/w (server).
what are the ways to implement it?

What is the problem? Run DBCA in the advanced mode and specify the required database character set for the new database.

Region type URL and character set encoding

Hello,
I'd like to include static html page using URL region, but there is some translation done between encoding of input static html page and output of HTML DB. Does anyone know how the file encoding is translateded when the page is rendered?
I have tried some encodings of input file (CP1250, UTF-8, Unicode) but it did not work.

Starting in Oracle 9i the National Characterset (NLS_NCHAR_CHARACTERSET) will be
limited to UTF8 and AL16UTF16.
For more details refer to The National Character Set in Oracle 9i and 10g
Any other NLS_NCHAR_CHARACTERSET will no longer be supported.
When upgrading to 10g the value of NLS_NCHAR_CHARACTERSET is based
on value currently used in the Oracle8 version.
If the NLS_NCHAR_CHARACTERSET is UTF8 then new it will stay UTF8.
In all other cases the NLS_NCHAR_CHARACTERSET is changed to AL16UTF16
and -if used- N-type data (= data in columns using NCHAR, NVARCHAR2 orNCLOB )
may need to be converted.
Edited by: DarkFiBrE72 on Sep 24, 2008 7:12 PMI'm not sure if the OP was referring to the National character set? Is this implied by the corresponding SQL Server characterset mentioned?
Otherwise I would assume we are talking about the Database character set, which allows numerous different character sets and types (single-byte, multi-byte, Unicode etc. depending on Oracle release).

Precautions i need to take when changing the Character set

Hi,
ORACLE VERSION: 10G Release 1 (10.1.0.3.0)
I am going to change my database's characterset from AL32UTF8 to WE8MSWIN1252 character set and AL16UTF16 NCHAR character set. So i have few questions for you.
1. What is the difference between Character Set and National Character set? Do i have to set both?
2. What are precautions that i need to take while changing the characterset?
3. What are JOB_QUEUE_PROCESSES and AQ_TM_PROCESSES parameters in Plain English? Why do i have to set these parameters to 0 as mentioned in this post below.
Storing Chinese in Oracle Database

1) The database character set controls (and specifies) the character set of CHAR & VARCHAR2 columns. The national character set controls the character set of NCHAR & NVARCHAR2 columns.
2) Please make sure that you read the section of the Globalization manual that discusses character set migration. In particular, going from UTF-8 to Windows-1252 is going to require a bit more work since the latter is a subset (and not a strict binary subset) of the former.
