NLS_LANG

Hi,
I have a JDBC program connecting to an Oracle DB. Where is NLS_LANG set ? It looks like we need to set it on both the client and Oracle DB OS's.
Can anyone explain the reasoning for setting this on the client or the DB OS ? What is the link between this setting and the Oracle DB char set.
I know that JDBC converts between UTF-16 and AL32UTF8 in some cases.
Thanks,
Mohan

Yes.
The scenario is this.
1. DB char set is AL32UTF8.
2. WebSphere Java code is unable to store data in the proper charset in the DB
3. DBA wants to set setenv NLS_LANG AMERICAN_AMERICA.WE8ISO8859P1 on the Oracle DB server and reboot it.
http://www.oracle.com/technetwork/products/globalization/nls-lang-099431.html#_Toc110410552
When I read this link it is not sure how this could help. Oracle DB server installation must already have set it to a default value.

How to setup NLS_LANG on Windows XP

Hi,
We have an oracle database with character set AMERICAN_AMERICA.US7ASCII setting. and our
production application inserts different language characters directly to the database without any
UTF8 conversion. Another function has been coded which can convert the different character set
to UTF8 via using convert() function before the client side can be used. it has been proved it works
fine with a PHP application which can show UTF8 on the webpage, based on a unix-box server.
Now I have installed a oracle application express server with character set AMERICAN_AMERICA.WE8MSWIN1252
(found from registry) on my windows XP. After reading the article from metalink
https://metalink.oracle.com/metalink/plsql/f?p=130:14:1393556852351104955::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,158577.1,1,1,1,helvetica
, I understood that oracle server side would convert the character to the client side if it found
their character set are difference, which is not what I want in this case, so I should set my client side as same as
server side so that no any conversion therefore the converted UTF8 code can directly delivered to front application.
I have try to set the oracle client side as AMERICAN_AMERICA.US7ASCII, WE8ISO8859P1 or others, none of them works.
Give you a simple instance here is that
1.Insert ZHS16CGB231280(chinese code) to Production database(US7ASCII)
2. retreive it by convert('string', 'UTF8', 'ZHS16CGB231280')
3. send to client side(characterset US7ASCII)
doesn't work
Does anyone has experience and point me out what wrong it is. it lasts me several weeks trying to
figure out, but failure.
Thanks for your help

Generally speaking, if you want to store chinese characters, your database character set must be able to store it correctly without using CONVERT function: you could use one of the
universal character set. I'm surprised that you are able to store chinese characters in the US7ASCII character set but I'm not surprised that it does not work in other cases.
The OTN NLS_LANG FAQ give some common values under Windows, assuming that each Windows node will only be used in one given national environment.

How do you set NLS_LANG environment variable in report builder

How do you set up the reports builder environment to display foreign fonts.
So far what I read makes me think that in report builder I have to set the NLS_LANG environment variable .
If anyone has done this is that true and if so how.
Also the languages I want to use are the following.
Armenian
Cambodian
Chinese
Russian
Tagalog
Vietnamese
How do I find the NLS_LANG environment variables for these.
Where I am at now+
I have to set the DEVELOPER NLS LANG. I see the NLS LANG in the registry and I guess I have to add the DEVELOPER NLS LANG.
Now I am searching for syntax. If anyone knows the syntax for those languages please let me know and how do I set more than 1 at a time.

Hello Howard,
Check out the following link here you can find your desired NLS parameters.
http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm
And about the NLS_LANG for developer why you want to create for developer. Its is already there in REGISTRY. Just seaching in developer registry you can find there.
how do I set more than 1 at a time.
You can set only one NLS_LANG parameter at a time.

How to set up multiple NLS_LANG or update the NLS_LANG in windows registry

Hi!
In our server machine, we have installed the Oracle Net Manager Version 10.2.0.0.0, which is used to connect to different oracle databases in different NLS_LANG settings (i.e., JA16SJIS, KO16KSC5601, WE8ISO8859P1). Currently, our NLS_LANG is set to "AMERICAN_AMERICA.UTF8". In order not to convert the character set to UTF-8 format, could anyone tell me:
1. how to set multiple NLS_LANG for different databases in registry
2. how to switch the NLS_LANG setting in registry programmatically in order to retrieve/view the data in the corresponding character set (same as the setting in Oracle DB) for the dedicated oracle database
Please advise. Thanks a lot
Best Regards
Pinga

1. how to set multiple NLS_LANG for different databases in registryBy default NLS_LANG registry settings is linked to the Oracle home and not to the database. I don't think that you can set a NLS_LANG setting for each database (unless you are using a command line tool and in this case you can set the NLS_LANG environment variable).
See also OTN NLS_LANG FAQ.

Multiple Database Instances on Single Server and effect of NLS_LANG

What is the effect of the NLS_LANG registry setting on a Windows server that is to host multiple database instance each created with a different database character set ? The server needs to support data in the following languages : Thai, Chinese Traditional, Chinese Simplified, Vietnamese and Korean. Selecting the Unicode character set(AL32UTF8) is not an option since the application is not Unicode complaint.
My understanding is that as long as NLS_LANG is set correctly on the client connecting to the particular database instance then the data will be stored correctly - is this correct ?
What should NLS_LANG be set to on the server if there are multiple oracle instances with different character sets ?

My question is not in relation to connecting to the database on the server itself but with regards to client connections. What I need to know is what is the effect of the NLS_LANG setting in the registry on a server that has multiple databases each created with a different character set ?
Say for instance, the server has two databases - one created with the character set ZHS16GBK and the other created with the character set JA16SJIS and NLS_LANG is set to SIMPLIFIED CHINESE_CHINA.ZHS16GBK in the registry on the server. Will Japanese data that is inserted into the database that has character set JA16SJIS be stored correctly when it is inserted from a client with NLS_LANG set to JAPANESE_JAPAN.JA16SJIS even though NLS_LANG is set to SIMPLIFIED CHINESE_CHINA.ZHS16GBK on the server ?

Purpose of nls_lang

Hi
What is the purpose of setting nls_lang before export or import?
What happens if I dont set it ?
As far as I understand, it is related to client issue. Is it again come into play if I do the export/import directly from server ?
Suppose I want to change characterset from WE8MSWIN1252 to UTF-8.
I took export.
Create new database with utf8.
and import.
Do I need to set nls_lang prior to import or export?
I appreciate if anyone clear my doubts.

If you use datapump, never mind. If you use exp,imp, the main reason why to set NLS_LANG is the characterset component of it. Set it to the appropriate character set of the computer, you do the exp and imp on. Else you might loose special characters stored in your tables. It is not necessarily the same as the database character set.

NLS_LANG value that suits Forms 10G and Database 11G wanted !

I can't believe how bad is to install Oracle Database and Oracle Forms on the same Windows Vista machine!
I had a problem in Oracle Forms 10g that prevents many items in the Form Builder menu from appearing in English Language and also prevents anything in the web-based forms runtime from appearing in English. I searched the forum for a solution and found that I have to set a NLS_LANG value in the environment variables equal to the following: AMERICAN_AMERICA.WE8MSWIN1256.
I did this and my Forms builder looked great. Everything in english with no problems. But now what ?! The Oracle Database itself refused to connect from all clients! It refused to connect from Forms Builder, SQL Deeveloper, and even from SQL PLUS! The error given is: ORA-12705: Cannot access NLS data files or invalid environment specified.
It seems that what I exactly need is a NLS_LANG value that will satisfy both Oracle Forms 10G and Oracle Database 11G that both are installed on the same Vista machine. The question is: What could this NLS_LANG value be?!
Thank you in advance

If you have connected to the database on which the form is based, prior to running the form from the Builder, the uname and password will automatically be passed in at startup and you will not be prompted.
If you would rather hard code a username and password, enter it in formsweb.cfg. For example:
SYNTAX:
userid=<USERNAME>/<PASSWORD>@<DB NAME>
EXAMPLE:
userid=scott/tiger@orcl
Remember that this change will only impact runtime and have no effect on the Builder.

Change Background_Color with set_*_property doesn´t work with NLS_LANG UTF8

Hi @all,
we changed our forms from we8iso8859p1 to utf8 and now we noticed that changing of background colors from canvases, items etc don´t work anymore.
I tried set_canvas_property, set_va_property, set_item_property.
When I start the form with NLS_LANG: GERMAN_GERMANY.WE8ISO8859P1 changing the colors works.
When I start the form with NLS_LANG: GERMAN_GERMANY.UTF8 changing the color don´t work.
We use Forms Version 6.0.8.11.3.
Are there any workarounds to change the colors when nls is set to utf8?
Thanks
Thomas

Hi,
I discovered following:
- if name of OU in AD is without space (e.g. test,sample) so DN record is test\,sample and user is moved into this OU.
- if name of OU in AD is with space (e.g. test, sample) so DN record is still test\,sample and user isn't moved.
So problem is with empty space. How can I preserve space in DN name? I found something in documentation but I doesn't work for me.
+Special Characters in FieldValues
If you have a field value with a comma (,) or double quote (") character, or you want to preserve leading or trailing spaces, you must embed your field value within a pair of double quotes ("field_value"). You then need to replace double quotes in the field value with two double quote (") characters. For example, "John ""Johnny"" Smith" results in a field value of John "Johnny" Smith. +
(from IDM Business Administrator's Guide, p.77)
Guided this information I put value of slctOrganizationalUnitUzivatele into "". But this didn't work. Is good idea to have space in DN?
Thanks for help.

Setting NLS_LANG=CANADIAN FRENCH_CANADA.WE8MSWIN1252 doesn't work Win64 bit

Hi,
I migrated my database Oracle 10.2.0.4 windows 32 bits to Windows 64 bits. On the new server 64 bits, I set registers key exactly the same way (NLS_LANG, NLS_DATE_FORMAT, etc.).
In 32 bits, when I started SQLPlus, I had the following output:*

To be sure it's the good key used by SQL*Plus, I voluntary changed the value of the Key NLS_LANG to an invalid value to see what would be the result
(for example: I omitted the first "A" in CNADIAN FRENCH_CANADA.WE8MSWIN1252). Now is the result:

ERROR:

Enter user-name:
That's the proof that I'm using the good key. Si why it doesn't work for NLS_LANG=CANADIAN FRENCH_CANADA.WE8MSWIN1252 ???
I tried with the same bad result with FRENCH_CANADA.WE8MSWIN1252.
Any idea?
Thank's

Sorry, I created the this thread in the wrong category ...

I'm quoting NLS_LANG FAQ http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm:
>
If NLS_LANG is not set in the environment, check the value in the registry:
SQL>@.[%NLS_LANG%].
If you get something like:
Unable to open file.[ENGLISH_UNITED KINGDOM.WE8ISO8859P1].
The "file name" between the braces is the value of the registry parameter.
If you get this as result:
Unable to open file ".[%NLS_LANG%]." then the parameter NLS_LANG is also not set in the registry.
Note the @.[%NLS_LANG%]. technique reports the NLS_LANG known by the SQL*Plus executable, it will not read the registry itself. But if you run the HOST command first and the NLS_LANG is not set in the environment then you can be sure the variable is set in the registry if the @.[%NLS_LANG%]. returns a valid value.
>
Maybe you have several NLS_LANG setting in the registry because you have several ORACLE_HOME ?

Strange Chars after modify reports.sh NLS_LANG

I had a problem when I modify NLS_LANG in reports.sh in linux. If i put NLS_LANG=PORTUGUESE_PORTUGAL.WE8MSWIN1252 my reports comes with strange some like greek characters. My database charset is WE8MSWIN1252.
My database v$NLS_PARAMETERS are:
NLS_DATE_LANGUAGE
PORTUGUESE
NLS_CHARACTERSET
WE8MSWIN1252
Anyone with same problem too?
Thanks

Sorry,
I forgot to mention that, I have already added 3of9 font in PPD files, by oversight i missed in my question.

Please suggest..

NLS_LANG conversion

Hi All
Ihave problem with importin data
import done in AR8ISO8859P6 character set and AR8ISO8859P6 NCHAR character set
export client uses WE8ISO8859P1 character set (possible charset conversion)
export server uses WE8ISO8859P1 NCHAR character set (possible ncharset conversion)
my data writing in arabic , now I see it qutaion mark(??????????)

It look like while exporting you had western character set not arabic character set.
Set the nls_lang as per your requirement and take an export again. Then, do the import with the same nls_lang settings.

Std::string NLS_LANG character sets

I'm an OCI user but not a pure one. Because I use the free available OTL (Oracle Template Library) from S.Kuchin which is a wrapper around OIC I hope this not off topic here.
The library offers the possibility to read database strings from VARCHAR2 fields to
a std::string. I know that oracle does character converting at client side controlled
via NLS_LANG environment variable.
It's clear to me that reading database strings to std::string is no problem for
one byte character sets liike ISO-8859-1. But how about when I let point NLS_LANG
to UTF-8 or chinese character set e.g. ZHT16BIG5 ?
Is it still safe to read the result to a std::string ?
For example I have a database with default characterset AMERICAN_AMERICA.WE8ISO8859P15. I stored some German umlaut in some
table. I wrote a small program using OTL and set NLS_LANG to UTF8 on client side.
I fetched the data from server to client, stored the data in a std::string, pushed them in a file and yes the data were stored as UTF8.
Is it really so simple or is it dangerous to read the UTF8-converted data to
std::string ? Wat is the common rule ? When may and when may I not read the data
to std::string ?

Character conversion and NLS_LANG

Hi,
The Oracle doc says that character encoding conversion for Java programs using the OCI driver is dependent on NLS_LANG. But the description of this was a bit confusing. As per the doc
"The JDBC OCI driver transfers the data from the server to the client in the character set of the database. Depending on the value of the NLS_LANG environment variable, the driver handles character set conversions in one of two ways.
1)If the value of NLS_LANG is not specified, or if it is set to the US7ASCII or WE8ISO8859P1 character set, then the JDBC OCI driver uses Java to convert the character set from US7ASCII or WE8ISO8859P1 directly to UCS-2.
2)If the value of NLS_LANG is set to a non-US7ASCII or non-WE8ISO8859P1 character set, then the driver changes the value of the NLS_LANG parameter on the client to UTF-8. This happens automatically and does not require any user-intervention. OCI uses the value of NLS_LANG to convert the data from the database character set to UTF-8; the JDBC driver then converts the UTF-8 data to UCS-2. "
Now refering to case1, assume the database character set is multibyte.Does this mean that the OCI C libraries first convert this to US7ASCII or WE8ISO8859P1 and then the Java driver does the conversion from US7ASCII or WE8ISO8859P1 directly to UCS-2. If that is the case, wouldnt information get lost during the first conversion.
Thanks,
Tom.

Yes this is true. For a multibyte database character set caution
must be taken that the client application NLS_LANG is not
US7ASCII or WE8ISO8859P1 or data loss can occur. An effort will
be made to remove the NLS_LANG dependency in a future release
because the current solution is imperfect.
