Jdbc & national chars

When I'm trying to fetch some data from oracle that doesn't stored in tables (e.g. select to_char(sysdate,'month') from dual; or error text) I get question marks ('?') instead of correct national characters. If I select national symbols from tables I get correct result. This problem exist with oci and thin drivers, with various jre versions, with different NLS_LANG values. Database charset is UTF8.
Can anybody show the way to get correct symbols instead of that question marks?
Thank you.

What do you mean? This is my font embedding window:
Going from top:
Font name
Name
Style
Checkbox'es: simulated bold, simulated cursive, bitmap text
Size
Then:
Export for AS and Export in frame 1
Indentifier (disabled)
Class
Base class
And:
Export for sharing
Import for sharing
URL (disabled)
Maybe I missed this field somewhere, but I see no option for exporting special chars.

Unit test fails after upgrading to Kodo 4.0.0 from 4.0.0-EA4

I have a group of 6 unit tests failing after upgrading to the new Kodo
4.0.0 (with BEA) from Kodo-4.0.0-EA4 (with Solarmetric). I'm getting
exceptions like the one at the bottom of this email. It seems to be an
interaction with the PostgreSQL driver, though I can't be sure. I
haven't changed my JDO configuration or the related classes in months
since I've been focusing on using the objects that have already been
defined. The .jdo, .jdoquery, and .java code are below the exception,
just in case there's something wrong in there. Does anyone have advice
as to how I might debug this?
Thanks,
Mark

Cannot create 'download' page for inline PDF viewing with IE

Description of Problem:
Typically, when you want to transfer a file to the client via code (cuz the
file is in a db, for example), you create a page that will change the
response headers and then spit out the file for them to download.
This works, however something with the response headers make it so IE does
not display a PDF if the 'Display PDF in browser' is turned on in the
Acrobat Reader. The page loads, but is blank.
code:
response.setContentType("application/pdf"); //this works well
response.setHeader("Content-disposition","inline; filename=" +"report.pdf" );
response.setContentType("application/pdf;charset=GB2312"); // can't work
response.setHeader("Content-disposition","inline; filename=" +"report.pdf" );
when response header containt national char
must set "useResponseCTForHeaders = true" in sun-web.xml and must use setContentType charset =XXX
Actual Results:
A blank page is shown
Expected Results:
The PDF is shown in the browser using the acrobat reader plugin.
How often does this happen?
Every time

hi kglad
thanks for the help im almost there but still not getting it
so currently my code is set up for an action over a button
using
on (release) {
getURL("www.mysite.com/my.mp3","_blank");
so do I keep the on(release and then add in the on (release)
then add in which part of the filereference class??
import flash.net.FileReference;
var listener:Object = new Object();
listener.onSelect = function(file:FileReference):Void {
trace("onSelect: " + file.name);
listener.onCancel = function(file:FileReference):Void {
trace("onCancel");
listener.onOpen = function(file:FileReference):Void {
trace("onOpen: " + file.name);
listener.onProgress = function(file:FileReference,
bytesLoaded:Number, bytesTotal:Number):Void {
trace("onProgress with bytesLoaded: " + bytesLoaded + "
bytesTotal: " + bytesTotal);
listener.onComplete = function(file:FileReference):Void {
trace("onComplete: " + file.name);
listener.onIOError = function(file:FileReference):Void {
trace("onIOError: " + file.name);
thanks a lot for your help!
var fileRef:FileReference = new FileReference();

How to store bit data in VARCHAR(4000) field?

Hi.
Please help!
We are porting some C/C++ software with embedded SQLs from NT/DB2 to Linux/Oracle.
On NT/DB2 we have some table to store file data in a VARCHAR(4000) blocks.
Table looks like this
CREATE TABLE FileData (filetime as timestamp not null, idx int not null, datablock varchar(4000) FOR BIT DATA not null, primary key (filetime, idx) );
As you can see DB2 has appropriate field modifier - "FOR BIT DATA" which makes DB2 storing data as-is, not converting characters.
I need to know - if it is possible to do the same in Oracle like in DB2?
If Oracle has some kind of field modifier like "FOR BIT DATA" in DB2?
If not, how can I do the same in Oracle?
The current problems are:
1) when application imports the file with some national chars the Oracle stores "?" in a database in place of national chars.
2) another piece of a problem - if file is more than 4000 bytes length, it reports the ORA-01461 error (see it is trying to expand some chars to UTF8 char which is not fit a single char, so finally - not fit the field size).
So, it seems that it cannot proceed national chars at all. :-\
For details please see enclosed [C code|http://dmitry-bond.spaces.live.com/blog/cns!D4095215C101CECE!1606.entry] , there is example how data written to a table.
In other places we also need to read data from FIELDATA table and store back to file (other filename, other location).
Here is summary on a field-datatype variants I have tried for the "datablock" field:
1) VARCHAR2, RAW, LONG RAW, BLOB - does not work! All reports the same error - ORA-01461.
2) CLOB, LONG - both working fine but(!) both still returns "?" instead of national chars on data reading.
Hint: how I did try these field types - I just drop the "FileData" table, created it using different type for "datablock" field and run the same application to test it.
I think I need to explain what the problem - we do not provide direct access to Oracle database, we use a some middle-ware. Middle-ware is a C/C++ software which also has a interface for dynamic SQLs execution. So, exactly this middle-ware (which is typically running on the same server with Oracle) receives the "?" instead of national chars! But we need it to return all data AS-IS(!) without any changes!!! That is wjhy I did ask - if Oracle has any options to store byte-data as-is?
The BIG QUESTION - HOW CAN WE DO THIS?!
Another thing I need to explain - it is ok to use Oracle-specific SQL ONLY IF THERE IS REALLY NO WAY TO ACHIEVE THIS WITH STANDARD SQL! Please.
So, please look on a C code (by link I have posted above) and tell - if it is possible to make working in Oracle the VARCHAR approach we using at the moment?
If not - please describe what options do we have for Oracle?
Regards,
Dmitry.
PS. it is Oracle 11gR2 on CentOS 5.4, all stuff installed with default settings, so Oracle db encoding is "AL32UTF8".
C/C++ application is built as ANSI/ASCII application (non-unicode), so sizeof(char)=1.
The target Oracle db (I mean - the one which will be used on customer site) is Oracle 10g. So, solution need to be working on Oracle 10g.

There is some contradiction in your requirements:
- if you want to store data as is without any translation use RAW or BLOB
- if you want to store national character data try to use NVARCHAR2 or NCLOB.Seems you did not understand the problem. Ok, I'll try to explain. Please look on the code sample I provided in original question
(I just added expanded data structures there, sorry I forgot to publish them when post original question):
EXEC SQL BEGIN DECLARE SECTION;
struct {
    char timestamp[27];
    char station[17];
    char filename[33];
    char task[17];
    char orderno[17];
    long filelen;
gFilehead;
struct {
    char timestamp[27];
    long idx;
    struct {
      short len;
      char arr[4001];
    } datablock;
gFiledata;
EXEC SQL END DECLARE SECTION;
#define DATABLOCKSIZE 4000
#ifdef __ORACLE
#define VARCHAR_VAL(vch) vch.arr
#elif __DB2
#endif
short dbWriteFile( char *databytes, long datalen )
short nRc;
long movecount;
long offset = 0;
gFilehead.filelen = gFilehead.filelen + datalen;
while ((datalen + gFiledata.datablock.len) >= DATABLOCKSIZE)
    movecount = DATABLOCKSIZE - gFiledata.datablock.len;
    memcpy(&VARCHAR_VAL(gFiledata.datablock)[gFiledata.datablock.len], databytes, movecount);
    gFiledata.datablock.len = (short)(gFiledata.datablock.len + movecount);
    exec sql insert into filedata (recvtime, idx, datablock)
      values(
        :gFiledata.recvtime type as timestamp,
        :gFiledata.idx,
        :gFiledata.datablock /* <--- ORA-01461 appears here */
    nRc = sqlcode;
    switch (nRc)
    case SQLERR_OK: break;
    default:
      LogError(ERR_INSERT, "filedata", IntToStr(nRc), LOG_END);
      exit(EXIT_FAILURE);
    offset = offset + movecount;
    datalen = datalen - movecount;
    gFiledata.idx = gFiledata.idx + 1;
    memset(&gFiledata.datablock, 0, sizeof(gFiledata.datablock));
    databytes = databytes + movecount;
    gFiledata.datablock.len = 0;
if (datalen + gFiledata.datablock.len)
    memcpy(&VARCHAR_VAL(gFiledata.datablock)[gFiledata.datablock.len], databytes, datalen);
    gFiledata.datablock.len = (short)(gFiledata.datablock.len + datalen);
return 0;
}So, the thing we need is - to put some data into the "datablock" field of following structure:
struct {
    char timestamp[27];
    long idx;
    struct {
      short len;
      char arr[4001];
    } datablock;
gFiledata;Then insert it into a database table using static SQL like this:
    exec sql insert into filedata (recvtime, idx, datablock)
      values(
        :gFiledata.recvtime type as timestamp,
        :gFiledata.idx,
        :gFiledata.datablock /* <--- ORA-01461 appears here */
        ); And then expect to read exactly the same data back!
The problems are:
1) Oracle make decision to convert the data we are inserting (why? and how to disable converting?!)
2) even if it inserts the data (CLOB and LONG field datatypes are working fine when inserting data with such static SQL + such host variable) then it became not readable! (why?! how to make it readable?!)
P. Forstmann wrote:
ORA-01461 could mean that you have a wrong data type for bind variable variable in your client code:Not me decided that host variable is the "LONG datatype value" - the Oracle make that decision instead of me. And that is the problem!
Looks like Oracle react on any char code >= 0x80.
So, assume if I run the code:
// if Tab1 was created as "CREATE TABLE Tab1 (value VARCHAR(5))" then
char szData[10] = "\x41\x81\x82\x83\x84";
EXEC SQL INSERT INTO Tab1 (value) VALUES (:szData);
Oracle will report the ORA-01461 error!
EXACTLY THIS IS THE PROBLEM I HAVE DESCRIBED IN MY ORIGINAL QUESTION.
So, problem - why Oracle make such decision instead of me?! How we can make Oracle insert data into a table AS-IS?
What other type of host variable we should use to make Oracle think that data is a binary?
void*? unsigned char? Could you please provide any examples?
Ok, you did recommend - "use the RAW datatype". But RAW datatype is limited to size 2000 bytes only - we need 4000! So, it is not match our needs at all.
Also you have mentioned "use BLOB" - but testing shows that Oracle reports the same ORA-01461 error on inserting data into a BLOB field from such host variable! (see the code I posted)
What also we can do?
Change type of host variables? BUT HOW?!

SQL Query very slow.

First time when i execute the query it takes huge time. but subsequent queries are faster. This is only if i pass same account and criteria again.
Observed that first time it goes for physical reads which takes time. and subsequent runs physical reads are less.....
Request suggestions.....this is account statement inquiry user may have 10000txns in a day as well
Bymistake earlier i raised this in "Oracle -> Text"
Slow inserts due to physical reads every time for fresh account i am passin
They suggested to use bind variable. But as i know, we are already using bind variables to bind account number and start and end date.

2. Why doesn't your INSERT query use APPEND, NOLOGGING and PARALLEL like the first query you posted? If those help for the first query why didn't you try them for the query you are now having problems with?
Ans :
I will try to use append but i cannot use parallel since i have hardware limitations.
3. What does this mean: 'Index referred is in_xface_addl_details_txnlog_3.'? You haven't posted any plan that refers to any index. Do you have an execution plan? Why didn't you post it?
Ans :
Plan hash value: 4081844790
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
| 0 | INSERT STATEMENT | | | | 5 (100)| | | |

| 5 | INDEX RANGE SCAN | IN_XFACE_ADDL_DETAILS_TXNLOG_3 | 1 | | 3 (0)| 00:00:01 | 1 | 128 |
4. Why are you defining 37 columns as CHAR datatypes? Are you aware that CHAR data REQUIRES the use of the designated number of BYTES/CHARACTERS?
Ans :
I understand and appreciate your points, but since it is huge application and is built over a period of time. I am afraid if i will be allowed to do change on datatypes. there are lot of queries over this table.
5. Are you aware that #4 means those 37 columns columns, even if all of them are NULL, mean that your MINIMUM record length is 1012? Care to guess how many of those records Oracle can fit into an 8k block? And that is if you ignore the other 26 VARCHAR2, NUMBER and DATE columns.
Two of your columns take 192 bytes MINIMUM even if they are null
CUSTOMER_NAME CHAR(192),
COD_ACCT_TITLE CHAR(192)
Why are you wasting all of that space? If you are using a multi-byte character set and your data is multi-byte those 37 columns are using even more space because some characters will use more than one byte.
If the name and title average 30 characters/bytes then those two columns alone use 300+ unused bytes. With 40 million records those unused bytes, just for those two columns take 12 GB of space.
WIth a block size of 8k that would totally waste 1.5 million blocks that Oracle has to read just to ignore the empty space that isn't being used.
I highly suspect that your use of CHAR is a large part of this performance problem and probably other performance problems in your system. Not only for this table but for any other table that uses similar CHAR datatypes and wastes space.
Please reconsider your use of CHAR datatypes like this. I can't imagine what justification you have for using them.
Ans :
I understand your points, but since it is huge application is built over a period of time. I am afraid if i will be allowed to do change on datatypes.
I have to manage in current situation. Not expecting query to respond in millisecs but not even 40secs which is happening currently.

Display data type

hi,
how to display oralce's data type from system table is there any system table to fetch the data types for that version i'm using Oracle 11g.
in sql server we fetch the details by using
select * from sys.types
this will return what the data types supported by that version
Thanks!

There is a package called STANDARD in the SYS schema that defines many of the standard datatypes and functions.
e.g.

How to set encoding type for e4x result

I have a application with front end Flex and Server side App
in Java. I am using HttpService to communicate to Java application
(Web). I am sending data in xml format to flex and parsing it as
e4x format. From service side I am setting the charset as
windows-1252 and xml encoding is also windows-1252. In Flex I am
getting some junk characters. But When I post the same http request
from browser, I am able to view the characters with expected
encoding.
Can anybody clue me on getting xml data in required encoding
type (charset) in Flex.
Thanks in Advance,
Gokul Ram.T

The message is old, but the problem is opened and I believe that many people have troubles with getting appropriate encoding in e4x result.
I have excactly same problem like Gokul, only difference is that I am trying to get ISO-8859-2 charset. HttpService deffinition looks like this:
var source:HTTPService = new HTTPService();
source.method = "POST";
source.resultFormat = "e4x";
source.contentType = "text/xml; charset=ISO-8859-2";
source.headers = {"Content-Type": "text/xml; charset=ISO-8859-2"};
So I suppose that everything what can be set is set. But still in result XMLthere are no national chars. I also get correct XML when I request it in browser, but requesting by Flex and HttpService makes problem.
Does anyone have same problem and find out something to handle this?

ADF 11g - Right Alt+A Shortcut

I noticed that in ADF Table input text fields is used shortcut Alt+A. This shortcut it is also polish national char (ą).
Any solutions for change it?

Simple script:
<html>
<head>
<script type="text/javascript">
function wyd(e){
document.getElementById('kctrl').value=e.ctrlKey;
document.getElementById('kalt').value=e.altKey;
document.getElementById('kkey').value=e.keyCode;
</script>
</head>
<body>
<input type="input" value="type here" onkeyup="wyd(event);" /> <br />
Ctrl: <input type="text" id="kctrl" /><br />
Alt: <input type="text" id="kalt" /><br />
KeyCode: <input type="text" id="kkey" /><br />
</body>
</html>If I push Alt+A then onkeyup event returns Ctrl+Alt+A. Probably ADF ignore Alt when checking highlight event in table.

This is not helping because it's not really related to a process.
I'm using the request value to show/hide an item.
As I'm losing the request value when I submit the page and get the errors, my item is not displayed anymore.
I will have a look at the url posted by Jari and keep you posted if this helps.

( SOLVED )gnome-terminal, su, sudo, gksu, gksudo does not work

Hello,
In my fresh installed gnome3 graphical environment, in gnome-terminal, I can not gain root access.
I've tried diverse su commands.
1. su command, ends with:
su -
Password:
su: Authentication failure
2. sudo command, ends with:
sudo -l
[sudo] password for root:
Sorry, try again.
[sudo] password for root:
Sorry, try again.
[sudo] password for root:
sudo: 2 incorrect password attempts
Of course - each time, I typed correct password.
In my sudoers file, group wheel ( into which belongs user I logged in ) has permissions to execute any command.
3. gksudo with debug:
gksudo -ld gnome-terminal
No ask_pass set, using default!

I've been asked for my password, not root, after typing I get "incorrect password attempt", if I type root pwd I get the same.
4. Same with this command:
gksu -ld gnome-terminal
No ask_pass set, using default!

In multi-user-mode I can login to root account.

Hurrican, ok, there is no need to install antother terminal, as I wrote it did not work also in xterm.
Yesterday evening, tired and sad that gk(su|sudo) still does not work,
as the "last chance idea", I logged in into multi-user mode ( init level 3 ) and changed root's password,
then loged in into graphical mode ( init level 5 ), start gnome-terminal and suddenly ... command "su -" started to work.
By the way, similar solution ( but with chroot ) has suggested Gulver in his post ( this thread, answer #2 ).
The question is, why root's password, set during install, after finished installation is recognized in text mode, but not im graphical ?
First root's password was really simple, like "dog4356", without any national chars.
You're right. I don't even have xterm installed so I guess I just singled out gnome-terminal and forgot that xterm also wasn't working.
Forgive me for my shaky advice. Like you I've been super busy, and sweating out a fever of 102 degrees (that's Fahrenheit no my
blood wasn't boiling ). Anyways, glad you got it working. After reading over the whole thread and thinking about it for a little bit, I
can't really make a good guess as to what was happening.
I'm sure you probably had tried this, but you could have typed the password out in the command line so you could see it. If there was
something wrong with it, it would have shown up there as well. If it was perfectly fine, then it would have been very, very weird.
The important thing is you got it working.
Merry Christmas.

Question about xsql:set-page-param

Hi!
I have construction like this:
<xsql:set-page-param name="ptk1" value="{@some_value}">
where {@some_value} contains national characters. And in ptk1 I have only question marks. If I use {@some_value} directly, for example <xsql:query ...> <![CDATA select ... where field={@some_value} ]]> </xsql:query> it works fine. I have
<?xml version="1.0" encoding="windows-1251" ?> in my xsql page.
Is it possible to get set-page-param working with national chars?
Thank you very much.

You've identified a bug in how parameter values are retrieved. I've filed Bug#1920676 to get this fixed.
Currently character set conversion is done between the servlet engine's default character set and the character set of the XSQL page template. The bug occurs because the character set conversion is being done in certain circumstances when it is not actually required.
Will post a status update when we've identified a fix.

Edit in procedure and functions

hi
I was previously under impression that you cannot use edit in procedure but recently i found this piece of code and it seems it compiles
create or replace procedure test is charcol char(32767);
charvaryingvar char varying(32767);
charactervar character(32767);
charactervaryingvar character varying(32767);
nationalcharvaryvar national char varying(32767);

stringvar string(32767);
varcharvar varchar(32767);
varchar2var varchar2(32767);
begin
     null;
end test;
however when i try something like this it does not compile
create or replace procedure myprocedure
(l_number number(10),
l_pre varchar2(10)) is
begin
     null;
end myprocedure;
why i am getting this behaviour

You are not permitted to explicitly constrain the size of formal parameters in >PL/SQLyes its but the first one also has edit or constraint in its declarations and it compile while the second one is not compiling
here is the code
create or replace procedure test is charcol char(32767);

I know that edit or precesion is not allowed in procedure, functions but in the first case we have precesion and its compiling.
any explanation?

Email from Flash - non-disabling TFs, encoding problem

Hi,
recently I create Flash-based contact form. I have 2 issues:
1. When user clicks the "Send" button, there is and additional layer over the form - Shape filled with black rectangle, 0.4 alpha and one more with window "Sending in progress". I noticed that it is possible to edit the form fields (these are TextFields with INPUT type). The image below is from my Flash projector - as you can see, there is "cursor" in "message" TF.
2. This form uses PHP to send emails by email() function. When I use my national chars, they aren't shown in sent email, there are rectangles. My .php file uses UTF-8 encoding and gets data from $_GET array and when I tries to send email from browser (just typing an address and my national chars in it), everything's okay. Is there a possibility to made Flash using UTF-8 encoding?
Thank you

OK. Now #1 problem is solved.
I still have 15 points to hand out
Edit: I've already found a solution on kirupa forums.

(V8) ORACLE8의 CHARACTER SET의 변경에 대하여

제품 : ORACLE SERVER
작성날짜 : 1997-08-26
Oracle8의 Character Set의 변경에 대하여
Oracle7에서 수행하던 DB의 DB character set(이하 dcs)을 변경하는 방법이
Oracle8에서는 공식적으로 지원하는 command로 변경되었습니다. O7에서는
props$ table의 값을 바꿈으로써 dcs를 바꾸던 방법의 결점은 다음과 같습니다.
1) 새로운 dcs가 올바른 dcs가 아닐 경우, DB를 다시 구동할 수 없슴.
2) 새로운 dcs가 이전 dcs의 super set이 아닐 경우, 새로운 dcs와의
character encoding 호환성 문제로 DB에 저장된 data를 올바른 의미
또는 올바른 값으로 사용할수 없슴.
3) dcs의 호환성 문제로 DB의 crash
물론 위의 문제는 dba의 능력에 따라 발생하지 않을 수도 있습니다. 이런 종류의
모든 문제를 해결하기 위해 O8에서는 dcs와 관련된 table들의 값을 변경하기
이전에 새로운 dcs가 올바른가를 확인하고, 새로운 dcs가 이전 dcs의 super set
인가를 확인하여 모든 것이 정상일 때에만 dcs의 값을 변경할 수 있게 하는 절차를
제공하게 되었습니다.
여기에서 super set이란 A라는 char set에 있는 모든 character가 B라는 char
set에서 똑같은 code 값으로 존재할 때 B는 A의 super set이라 합니다.
즉 한국 환경에서는 다음의 경우가 해당됩니다.
1) ko16ksc5601은 us7acsii의 super set이다.
2) utf8(unicode 2.0의 변형)은 us7ascii의 super set이다.
3) utf8은 ko16ksc5601의 super set이 될 수 없다.
- utf8의 code range는 ko16ksc5601의 super set이지만, code value는
같지 않으므로 dcs 변경 시의 super set은 아니다.
기존의 DB가 us7ascii이고 client 역시 us7ascii를 사용하여 한글 데이타를
DB에 저장시킨 경우 대부분 ksc5601 encoding scheme을 사용하여 한글을
입력시킵니다. 이 때 DB에 입력된 "가"는 0xb0a1으로 저장되는데, 이 DB를
ko16ksc5601으로 변경시키면 ksc5601에서 역시 "가"의 code 값은 0xb0a1이므로
변경된 DB는 정상적인 동작을 하게 된다.
그러나, utf8 encoding scheme을 이용하여 "가"를 입력시키면 DB에는 0xeab080
으로 입력되므로 DB를 ko16ksc5601으로 변경시킨 경우 client에서 이 값을
access하면 다음의 경우가 발생합니다.
1) utf8을 지원하는 기계에서 ko16ksc5601을 이용하는 경우
-> 이전에 입력된 "가"를 볼수 있음
2) 1)을 제외한 경우 정상적으로 data의 의미를 해석할수 없음.
즉 이전 DB에 data의 입력 방식이 ksc5601인 경우 DB를 ko16ksc5601으로
변경하면 아무런 문제 없음. 그리고 이전 DB에 utf8의 입력 방식을 사용한 경우,
DB를 utf8로 변경하면 문제없음. 즉 한국 환경에서는 us7ascii에서
ko16ksc5601으로 변경하는 경우와 us7ascii에서 utf8으로 변경하는 두가지
경우 밖에 존재하지 않는다.
1) us7ascii ----> ko16ksc5601
2) us7ascii ----> utf8
또한 O8에서는 DB의 database character set(dcs) 이외에 national character
set(ncs) 이라는 secondary character set을 지원합니다. 이것의 특징은
문자의 길이가 고정되어 있다는 것입니다. 즉, table 생성 시 특정 column을
nchar 혹은 nvarchar2로 선언하여 입력 시 N'a가'라는 data가 입력되면 이 값은
내부 처리 시, 저장 시, 외부 출력 시 0xa3e1 0xb0a1이라는 문자 당 고정 길이를
갖는 값으로 변경된다. 물론 이런 형태의 지원은 성능 향상을 위한 것이다.
이런 nchar, nvarchar2의 encoding scheme 역시 data base가 생성될 때
지정되고, DB의 dcs과 같은 방법으로 변경될 수 있다. 한국 환경에서 사용할 수
있는 ncs는 ko16ksc5601fixed와 ko16dbcsfixed라는 두 가지가 있는데 이것들은
Oracle 8.0.4부터 지원된다. 그런데 문제는 national char set 변경 시 역시
super set으로 밖에 변경할 수 없다는 제약이 있는데, 일반적인 설치 시 DB의
dcs와 같은 값으로 ncs가 지정된다.
1) ko16ksc5601fixed는 us7ascii의 super set이 아니다.
2) ko16ksc5601fixed는 ko16ksc5601의 super set이 아니다.
3) ko16ksc5601fixed는 utf8의 super set이 아니다.
그러므로 ncs를 ko16ksc5601fixed 혹은 ko16dbcsfixed로 지정하고자 하는
경우에는 DB의 생성 시 지정할 수 밖에 없다. 즉 "create database ..."에
반드시 지정되어야 한다.
또 한가지 고려 사항은 dcs와 ncs의 관계인데, 서로 다른 dcs를 사용하는
server/server, server/client의 경우 code conversion의 주체는 dcs이다.
즉 ncs는 dcs의 값으로 변경되어 상대방의 dcs로 변경되고, 이것은 다시 ncs로
변경되어 DB에 저장된다. 즉 ncs의 code 범위가 dcs보다 크다면 dcs에 포함되지
않는 ncs의 값은 default replacement character인 ?로 대치되어 전달된다는
것이다. dcs와 ncs의 관계는 code range가 초점이 된다.
1) us7ascii(dcs)에 ko16ksc5601fixed(ncs)를 사용할 수 없다.
2) utf8(dcs)에 ko16ksc5601fixed(ncs)를 사용하면 char를 nchar로 변경 시
data를 loss을 가져올 수 있다.
3) ko16ksc5601(dcs)에 ko16ksc5601fixed(ncs)의 사용은 문제 없습.
4) utf8fixed 형태의 char set은 현재까지 지원되지 않음.
Oracle8의 Character Set의 변경 시 지원되는 command
기존 DB의 char set이 us7ascii인 경우 DB char set의 변경은 ko16ksc5601
혹은 utf8으로 밖에 변경시킬 수 없다.
