How to SET CHARACTER SET UTF8

I am looking to execute something like the stmt "SET CHARACTER SET UTF8"
However if i put the above stmt in a SQLDBC_Statement_execute call, i get fail message.
I should also mention here that, SQLDBC_Connection_connect call provides a way to provide the character set as one of the parameter. Is that the only way we can set character set from an application while using SQLDBC ?

Hi Lars,Elke and Thomas,
Thanks to all of you for your valuable input. Honestly speaking i'm little lost on how to go about this requirement of unicode support for my application. Please allow me some more time to investigate this and then get back to you.
In my application for all other databases a simple execution of "SET CHARACTER SET UTF8" is all that's been done to set the support for UTF-8. So, I really need to figure out what all changes needs to be done in the app if this is not going to work.
In the meantime something more caught my attention while i was using this command:
sqlcli MAXDB1=> \dc domain.columns
Table "DOMAIN.COLUMNS"
Column Name
Type
Length
Nullable
KEYPOS
SCHEMANAME
CHAR UNICODE
32
YES
OWNER
CHAR UNICODE
32
YES
What does the type 'CHAR UNICODE' for Type means here?

Character sets - UTF8 or Chinese

Hi,
I am looking into enhancing the application I have built in Oracle to save/display data in Chinese & English. I have looking into how to change the character set of a database to accept different languages i.e. different characters.
From what I understand I can create a database to use a Chinese character set (apparently English ascii characters are also a part of any Chinese character set) or I can set the database to use a unicode multi-byte character set (UTF8) - which seems to be okay for all languages.
Has anyone had any experience of a) changing an existing standard 7 byte ascii database into database which can handle Chinese and/or b) the difference/ implications between using a Chinese and unicode character sets.
I am using Oracle RDBMS 8.1.7 on SuSE Linux 7.2
Thanks in advance.

If the data is segmented so that character set 1 data is in a table and character set 2 data is in another table then you may have a chance to salvage the data with help from support. The idea would be to first export and import only your CL8MSWIN1251 data to UTF8. Be careful that your NLS_LANG is set to CL8MSWIN1251 for export so that no conversion takes place. Confirm the import is successful and remove CL8MSWIN1251 data from database. Oracle support can now help you override the character set via ALTER database to say MSWIN1252. Now selectively export/import this data, again make sure NLS_LANG is set to MSWIN1252 for export so that no conversion takes place. Confirm the import is successful and remove MSWIN1252 data from database. And then do the same steps for 1250 data.

How to set NLS character set for report 9i servlet output?

Hi,
I am running a Reports 9i report. My problem is that the output HTML file is UTF8 encoded while ALL my 9iASR2 registry setting are set to EEISO8859P2. When I issued the http://<host:port>/reports/rwservlet/showenv?server=servername command it returned that the NLS setting is UTF8.
Can somebody please help me, how to set this environment variable for the report servlet to EE..P1? Thank you in advance.
Regards,
Tamas Szecsy

Dmitry,
recently I got this from Oracle support. :-(. Currently when I set the Windows 2000 local and default local to Hungarian and the charset to EE..P2 then I get Central-European encoded charset. I think you will have to experience around to get correct result (if it is possible at all).

This is bug Number 2472932 NLS:RWSERVLET SETS INVALID CHARSET AT THE HTTP HEADER
marked as fixed in 9.0.2.2 . unfortunately this bug is not published so I will not be able to sent you the bug as a whole but here is problem description in bug:
iAS9.0.2.0.1 (Reports9.0.2.0.1) on Solaris2.8
Running rdf with rwservlet sends the invalid charset at the http header.
Say ias is up with LANG=C, http header for the rwservlet
is always sent as "iso-8859-1" regardless of rwserver's NLS_CHARACTERSET.
This is the TCP/IP packet for the GET /reports/rwservlet?report=xxx&....
HTTP/1.1 200 OK Date: Sat, 20 Jul 2002 01:15:37 GMT Cache-Cont

cle HTTP Server Oracle9iAS-Web-Cache/9.0.2.0.0 (N) Content-Leng
th: 6908 Content-Type: text/html; charset=ISO-8859-1 Set-Cooki
In this example, to produce a html with other charset than
iso-8859-1,usually the outputted html has the charset information at
meta tag by setting "Before Report Value" property in rdf.
However charset in meta tag is less priority than http header, browser
such as IE6 or Netscape7 firstly displays the page in iso-8859-1.
Hence the characters other than iso8859p1 gets garbage.
To workaround it with IE6/NS7, set proper encoding manually.
('View'-'Encoding' for IE 'View'-'Character coding' for NS7 )
However, NS4.7 does not have workaround for it.
Besides, starting opmn in LANG=ja, the rwservlet's http header becomes
Shift_JIS!!. Thus rwserver seems to set the http header based on the
LANG on Solaris.
To fix these issues,
- The http header for rwservlet shold be based on the nls_characterset
for the rwserver.
This is no problem for reprots jsp run.

NATIONAL CHARACTER SET UTF8

Hi,
on 10g, on Win 2003, how to verify if database is NATIONAL CHARACTER SET UTF8 ?
Thank you.

SELECT *

Thanks
Muhammad Nadeem

Nadeem,
If you have database 10g, look into function REGEXP_REPLACE. Otherwise you can also try this (you might already know).
SELECT SUBSTR('CHHOCMIPO07020001', 1,2)||'-'||SUBSTR('CHHOCMIPO07020001' ,3,2)||'-'||
SUBSTR('CHHOCMIPO07020001' , 5,2)||'-'||SUBSTR('CHHOCMIPO07020001' , 7,3)||'-'||
SUBSTR('CHHOCMIPO07020001' , 10,2)||'-'||SUBSTR('CHHOCMIPO07020001' , 12,2)||'-'||
SUBSTR('CHHOCMIPO07020001' , 14,4)
FROM dual
CH-HO-CM-IPO-07-02-0001
If you have to use this at many places, create a function, pass the raw value, manipulate the string and return.

How to set focus on field having data type other than character(eg. NUMC)

Hello all,
I have developed one screen having table control inside. In table control suppose if numeric type field is blank(eg. Employee number of data type NUMC), system should throw error message and should put cursor focus on that perticular filed. In the same table control for fields of data type 'CHAR', I have done this using 'SET CURSOR FIELD' .
Please, suggest me how to set cursor focus on the fileds of data type other that character(eg. NUMC)

Have you tried it? SET CURSOR FIELD ... works fine for type 'N' fields in a table control. The restriction is 'character-type' and 'flat'. Type 'N' (or NUMC-like) fields are both.

How to set Weblogic 5.1 server to display UTF8 characters

Hi all,
Does anybody know how to set up Weblogic 5.1 server in order to display UTF8
characters such as Japanese characters?
I am able to display utf8 in Tomcat but not in Weblogic. All I did for
Tomcat is to change the content type of the servlets.
Thank you for your help.
Danh

DO you have servlets which print utf-8 data to the client?
If yes then you can just call response.setContentType("text/html;
charset=UTF-8");
and the response will look as expected.
for jsps :
<%@ page contentType="text/html; charset=UTF-8" %> should do the trick.

The .js file and the html need to have the same encoding. If
your html uses iso-8859-7, then the .js must also use that. But if
the original text editor created the .js file using utf-8, then
that is what the html needs to use.

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.

How we set up multiple websites on OSX Server

BACKGROUND
After fiddling and futzing around for weeks (actually since last year) I've finally figured out how to set up multiple websites (virtual sites) using one port and one IP address. While there seems to be lots of discussion on this topic, it seems that the basic assumption is that one knows everything about websites, DNS and all that stuff, which I do not.
When our network was originally established the engineer set up a wiki and also configured webmail, so we had two sites, one secured for mail and the other open for Calendar and the wiki. We were not hosting any websites locally because our school website is hosted by a company in New England.
This year I wanted to set up websites for teachers and students. As great as the wiki is, there are some things it just can't do as well as a website. So I figured if I set up the sites teachers could link back and forth from one to the other. In addition kids could now start to use a real website instead of the cobbled together file mess I had when we ran a Windows network. Also iWeb is a much more accessible tool than FrontPage.
SERVER SIDE:
Snow Leopard Server - 10.6.4
There are two - actually three pieces if you want your iWeb clients to connect to the server: Server Side Web Services, DNS and, in my case, FTP.
================================================ SERVER SIDE - WEB SERVICES
If you haven't turned on Web services, you'll need to open Server Admin and do that. If you don't know how to set up web services - just reply and I'll step you through that as well.
Once web services are set up and turned on, you'll see it listed under your server’s name in the Server Admin sidebar. Click on "Web" and then click on the "Sites" tab at the top of page. This is where you list all your sites.
Click the plus button and enter the fully qualified name of your site, for example: "students.myschool.org". Don't use the defaults here (no name) - that's what got me in trouble before. BE SPECIFIC!
You'll be looking at the "General" tab (the other tabs, "Options", "Realms", etc. we'll deal with in a second).
On the "General Tab", the default IP address ("any") and port (80) is just fine. We'll run everything over port 80. (Apache figures all the virtual site stuff out - you don't need your rocket science degree for that.)
"Web Folder:" is important because this is how you'll "segment" your websites. While I would NEVER do this again, we have a solid state hard drive for the OS and a RAID array for our data files. IF you have that, make sure you do NOT use the default "Web Folder" because it will store all your files on your solid state drive. There may not be enough room, over time, on that drive. I've not experienced it yet, but it's my understanding that if the drive fills up, the server shuts down.
I store my web sites on a folder on the RAID array.
Everything else on that tab can be left as the default. (Just make sure that you have an "index.html" or "index.php" file in your web folder root, but iWeb will take care of that for you.)
I would put in your email address in the "Administrator Email:" field.
Under "Options" you really don't have to put anything. I've tested making websites with iWeb and it doesn't appear that anything needs to be checked.
Nothing needs to be entered in "Realms" as well from what I see working w/ iWeb.
The defaults in "Logging" are fine.
You can leave "Security" alone, but we do have a (self-issued) certificate listed for our webmail site.
"Aliases" is important. Under "Web Server Aliases" you enter how you want the site to respond to when users type in a URL in their web browsers.
When our web server was initially set up the engineer set up "wiki.myschool.org" on port 80 and "mail.myschool.org" on port 443. In the aliases section was nothing but a "*" (the wildcard character). That means, from what I can figure out, that the webserver will respond to these sites regardless of what is typed in the URL. (Well, something like that - point is, if you create OTHER websites, you'll NEVER get to them because the wildcard character in the "Aliases" section, in effect, grabs those web requests and redirects them to the sites that are already there.
In my case I deleted both of those wild card characters. For my "wiki.myschool.org" site, I entered "mail.myschool.org". That means if you type EITHER "wiki." or "mail.", go to the site that’s stored in the “Web Folder” we set up when those sites were created.
For "mail.myschool.org" I just DELETED the wildcard character. I wanted that site (since it was secured) only to respond to "mail." - nothing else. (You're not going to that secured site for any other reason than to get your mail.)
"Proxy" can be left blank. Have no idea what that does. As time permits I'll do some research and figure out what it's used for.
"Web Services" is if you want to provide any MORE services to this particular site. Most likely you'll want to uncheck all the boxes. For our "wiki." site, we have checked "Wikis", "Blogs", and "Calendar". For our "mail." site we have those checked PLUS "Mail".
I would create a separate "Web Folder" for each of your sites. I don't know if that's a requirement but for housekeeping purposes, I would keep the sites separated. And I SUSPECT that it's "best practice" to separate your wiki from your other websites.
SERVER SIDE - DNS
OK...now you have to make your site reachable and the only way to do that is to set up DNS so that folks don't need to type in the IP address of your web server. You need to set up DNS inside your network and, if you want folks in the outside world to reach your website, you'll need to set up an external DNS as well. I'm going to cover INTERNAL DNS - if you don't know how to set up EXTERNAL DNS - reply or email me and I'll post those instructions.
Most likely you have already created Zones for you network...all you really need to do is create "Aliases" so that when you type "students.myschool.org" your web browser will know that site resides on IP address XXX.XXX.XXX.XXX.
If you've set up Zones then you already have a "Machine" setting that translates your server’s name to an IP address and vice versa.
All you need to do is create an "Alias" (CNAME) record for, in this case, "students". You’ll see the choices for types of records when you click the "Add Record" button.
There are only two fields to configure for a record: "Alias Name" - in this case "students" and "Destination" - in this case "servername.myschool.org". (You've already entered a machine record that says "servername" = 192.168.1.x.)
That's it for Internal DNS.
SERVER SIDE - FTP
Now you have to get iWeb to communicate with the webserver.
There are only three ways iWeb will communicate with webservers: MobileMe, Local Folder and FTP Server.
Local Folder is really only practical if you want to host a website on a laptop (I was blown away initially when I found out that all Macs had a built-in web server - how neat is that?). I think there are some very cool things teachers could do with configuration, and, of course, you wouldn't need to set up any web services on the web server, but that's for another discussion. You need to set up FTP services on the web server.
Turn on and enable FTP on your webserver.
You can leave the defaults for "General", "Messages" and "Logging". "Advanced" is the only thing you want to set. I set "Authenticated Users See:" to "Home Folder Only". I set the "FTP Root" to the same root folder in which I plan to store my web sites (/VOLUMES/RAID Array/WebServer/Documents). This setting sets that folder only to be accessible via FTP.
I would suggest returning to your DNS settings and adding one more "Alias". Set "ftp." to point to your webserver. Why? So folks can edit their sites from home (see below).
CAVEAT: If you are running FTP on other servers, make sure that the settings here do not conflict with the settings on the other servers. For example, I'm running FTP on my file server so that my scanners can communicate with it. However, I configure my FTP settings by machine name and NOT "ftp.myschool.org".
================================================
CLIENT SIDE - CONFIGURING iWEB
Now you have to configure iWeb so that it will communicate with your server.
Click on the "Site" icon so that "Site Publishing Settings" appears.
Publishing:
"Publish to:" = "FTP Server"
You can set the "Site name:" and "Contact email:" to whatever you want. But see below!
FTP Server Settings:
"Server address"=ftp.myschool.org (you could also enter in servername.myschool.org or the IP address. However, if you want folks to be able to work on the site from home, you will need to configure external DNS for that. If you use the IP address, you're out of luck for remote access to the site. (You can do it but it's beyond the scope of this discussion.)
"Username" & "Password" should be your user's network login credentials.
"Directory/Path" - this is important. Remember, you set your "FTP Root" to be "/VOLUMES/RAID Array/WebServer/Documents". If you leave this field blank then the website will be dumped into this folder. If you are only setting up one site, that may be OK. However I wanted to set up a "students" site folder, a "faculty" site folder and a separate site for our literary magazine.
THEREFORE: I have, in my ..../Documents folder (on the server), a "students" folder, a "faculty" folder, and a "litmag" folder.
SO...in my "Directory/Path:" field, I have "/faculty". That means the full path to this website is "ftp root/faculty" or "/VOLUMES/RAID Array/WebServer/Documents/faculty" (You don't need a trailing "/" character. iWeb will automatically append the folder for you user depending on what you entered in "Site Name:" in the "Publishing" area.
Website URL:
This is the root website depending on whether it is "students" or "faculty". Since iWeb will append the site name to this root website, I accomplished what I hoped to accomplish in this post (http://discussions.apple.com/message.jspa?messageID=12288561#12288561).
Faculty sites will be @ http://faculty.myschool.org/username. Students @ http://students.myschool.org/username. PERFECT!
iWeb is such a GREAT tool - NOW the kids can start using it!
I want to reiterate that this works for our school but it should work for you as well. There may be better ways to do this but it works for us.
Hope this has been helpful and you won't have to spend weeks trying to figure this all out by yourself!

OK...here's how we did it.
To get access to the website you created from outside your network there are a couple of steps.
First, you have to have a STATIC IP address from your ISP. If you have a T1 circuit, no problem...you usually get a couple of static IPs you can use. However, if you have a cable modem circuit, most likely you have a dynamic IP address which changes when you connect to the internet. Usually a static IP will cost a bit more because the ISP has to go through a couple of steps to set it up for you. But once you have the address, you now have a way for folks outside your network to connect with you.
(I’m also assuming that you use a router of some sort through which traffic flows out to the internet and that you aren’t using connection sharing or something like that.)
The next thing you need to do is have your new static IP address associated with the server on which you are hosting your website. You've probably already done that if your website works inside your network. However, you've associated a private ip (192.168.x.x, etc.) to your web server. That doesn't mean anything to folks on the outside because private IP addresses are just that - private - folks can't access them. (I won't get into VPN because that's a whole other topic.)
The way you associate your new static IP address to your web server is through some sort of dns application from your ISP. For example, we use TierraNet to manage our external DNS information. They have a web interface control panel that is very similar to the DNS interface for XServer. You can create CNAME records (aliases - other ways that folks can access your servers).
Basically you create an "A" (CNAME) record with a fully qualified domain name (e.g. webserver.myschool.org) and point it to your public IP address (XXX.XXX.XXX.XXX) which you just got from your ISP. It's going to take a while (24-48 hours) for this change to take effect. BTW, you can create as many “A” records as you want. For example mail.myschool.com and wiki.myschool.com could point to the same place.
You want to make sure that the fully qualified domain name you enter in the external dns utility matches the name you used when you created your internal dns records on your XServer.
OK...so now folks can get to your domain - but, remember, you have a private network IP scheme between them and you. You now have to tell your router that when web traffic arrives, allow it inside the network and direct it to your web server.
Let's say your public IP address is 205.100.112.50 and your web server is 192.168.0.5.
You have to create, in your router’s "Security Zone" (router companies call them different things) a couple of rules. Usually the first rule is: "Let everything inside the network get out to the web." You've probably already done that if folks inside the network can reach the internet.
You then have to tell the router to allow web traffic (port 80) into your network AND redirect that traffic to 192.168.0.5.
We use AdTran routers and they have a web interface which allows you to write "rules" affecting public and private traffic. Public is folks outside the network, private is folks inside.
AdTran calls them "Security Zones" and you modify those zones with policies.
So my "Policy" would say, in the above example, redirect traffic from my public IP (205.100.112.50) -> to my web server -> (192.168.0.5).
THEN you have to modify this policy with what AdTran calls "Traffic Selectors". You've said, OK, you can get in, but WHAT can get in?
The "Traffic Selector" is written to say: "Permit" "TCP" traffic from 205.100.112.50 only through Port 80. (That's the port that web traffic goes over. If you wanted a secure website, you'd add another traffic selector that opens port 443, for example.)
I'll tell you I'm no genius when it comes to this. I called AdTran and had them configure my router for me. I told them what I wanted done, they remoted into the router and configured it. But then I could go to the web interface and see what they did and then added rules later on when I wanted, for example, to get access to the network via Apple Remote Desktop or VPN into the network on my iPad.
I'd bet that your router has a maintenance agreement that includes this service and if it doesn't it should have.
I did find that I still had issues when I tried to set this up originally and it had to do with the ORDER of the policies. I can’t remember exactly what the issue was, but, effectively one of the policies highjacked traffic before the policy that I wanted got triggered. Simply moving them around in the list fixed that issue. So if you have this set up but still can’t access the site, check the order of your rules.
I don’t know if that helps or not, but I try to think about this stuff conceptually and then get someone to help me with the details. I work with this stuff so infrequently that I forgot how I did something 6 months or a year ago. I’m in the process of creating a wiki for the school which documents all this stuff, but that’s a major undertaking.
Cheers,
John
