• Character set of database and the national character set?

  Hi all
  
  I'm sorry if the question is stupid.
  
  why we need a so-called "national character set"?, I think it's important to keep the consistency of the character set, and this thing "national character set" really confuses me.
  
  in my opinion, if you are in English speaking countries, use ASCII coding such as your database character set, if not, just use you UNICODE, everything should be good, why?
  
  Thanks in advance.

  For Oracle Database, database character set is for the data types CHAR, VARCHAR2 and national character set to NCHAR, NVARCHAR2, and NCLOB and CLOB. Please read http://download.oracle.com/docs/cd/E11882_01/server.112/e10729/ch6unicode.htm#CACHCAHF.

• "testing" a new character set

  11.2

  We have two environments. CHOOSE the value OF V$ NLS_Parameters WHERE parameter = "NLS_CHARACTERSET"; Returns WE8ISO8859P1 AL32UTF8 and one in the other. Asked me to 'test' the support for multibyte characters and see what we need to do.

  I don't know how to approach the issue. So I went to the basics of loading of SQL * Plus and execute: SELECT 'Ä' FROM Dual;

  In WE8ISO8859P1 result:

  '

  -

  ?

  In AL32UTF8:

  '?'

  ---

  ?

  The only difference seems to be the display of single quotes in the header.

  What should I configure SQL * more? Is there a 'simple test' to show the difference between the two environments?

  Your task is not well defined. You cannot 'test data' unless you want to repeat that all the thousands of tests run by Oracle to test its product :-)  You can test some features in the database, but more often, you want to test a business with the database application.

  Certainly, an AL32UTF8 database can store data in any language supported by Unicode. You don't have to test this possibility. Thousands of databases with this character set and store data from around the world. However, AL32UTF8 is a multibyte character set. In other words, you need to store a lot of characters may have different codes of those in a database of the WE8ISO8859P1 and these codes can have more than one byte. Depending on how the columns of the table are defined, lengths of scope are defined, the application is configured, etc, you may or may not notice problems. As you can see, you need test a particular application to useful tests.

  If you want to just test the entry of accented Latin characters of languages of Western Europe on an American or a Western European version of Windows, then:

  -Open Command Prompt

  -Run:

  C:\ > chcp

  Should display:

  Active code page: 437 (or 850)

  If you see 437, enter:

  C:\ > set NLS_LANG =. US8PC437

  If you see 850, enter:

  C:\ > set NLS_LANG =. WE8PC850

  Then, run SQL * more (in the same window from command line!):

  C:\ > sqlplus...

  You should be able to enter Western European characters in the WE8ISO8859P1 database and the AL32UTF8 database with this configuration. Note, WE8ISO8859P1 can't stand not all characters available under Windows. For example, it does not support the Euro character.

  However, I recommend Oracle SQL Developer to test the characters entry in a database. It requires no any configuration for most popular languages. Configuration of fonts in the JDK can prevail for lesser-used languages.

  Thank you

• character set

  Hello
  
  Can we change the character set, and gather for a particular column in an oracle database?
  
  Thanx

  Character set AL32UTF8 change, use the Migration Wizard for database for Unicode (http://www.oracle.com/technetwork/products/globalization/dmu/overview/index.html). Its documentation has interesting information about the migration process.

  Oracle has currently no rankings assigned to data (columns, database). Ranking is specified dynamically through the settings of session NLS_SORT/NLS_COMP, or specified explicitly in calls to sensitive ranking functions selected: NLSSORT, NLS_UPPER, NLS_LOWER and NLS_INITCAP.

• build the new database through scripts must understand Spanish character sets.

  Hello gurus,
  I need to some simple tips, a good chance for some quick points for you.
  I've never built a database to understand any different other than the U.S. English character set. I now have to build a database that will be used for characters Spanish-keyboards, etc. But I will use English to install 11g software. I just want to be able to show the Spanish characters in the data for the names of clients.
  I will create the database with scripts that I did to make the standard model for data files, control files, etc..
  Then I import in a dump that I did and that was done with American English character sets.
  The system is 11g (11.2.0.3.0) on Linux Enterprise Server 5.8.
  I thought I'd use the AL32UTF8 character set, but I'm not sure where to use them.
  My original test showed no Spanish characters for names of customers as the "tilda" or "sueano" (excuse my spelling). But in this case I did the exceptional for Spanish, I used only the construction of standard American English (no change in the file init.ora or original database create script).
  
  How can I adjust my settings file for the initial creation of the database model to be able to understand the Spanish character set and still be able to import my dump error-free file.
  
  EXAMPLE of a build script:
  
  CREATE DATABASE mynewdb
  The USER SYS IDENTIFIED BY sys_password
  The USER IDENTIFIED BY system_password SYSTEM
  LOGFILE GROUP 1 ('/ u01/app/oracle/oradata/mynewdb/redo01.log') SIZE in the 100M.
  GROUP 2 ('/ u01/app/oracle/oradata/mynewdb/redo02.log') SIZE in the 100M.
  GROUP 3 ('/ u01/app/oracle/oradata/mynewdb/redo03.log') SIZE 100 M
  MAXLOGFILES 5
  MAXLOGMEMBERS 5
  MAXLOGHISTORY 1
  MAXDATAFILES 100
  CHARACTER SET US7ASCII
  NATIONAL CHARACTER SET AL16UTF16
  
  If I replace to AL32UTF8 AL16UTF16 NATIONAL CHARACTER SET, will it work to show the Spanish characters?
  
  Sorry for the long-winded question, any advice will be great.
  
  Fortunately,
  Shawn

  Hello
  the national character sets is for the column as nvarchar types not for normal varchar data types. So if your dump file contains column types, you also need to set. The character set is for normal column as a varchar types. The use of unicode is best practice if you use the multiel language, but keep in mind that multibyte character set can be a problem when importing because varchar2 (10) means byte 10 and not 10 characters, so mistakes as an identifier for a long time may occur when importing.
  You can create the database.

  See this documentation:
  http://docs.Oracle.com/CD/B28359_01/server.111/b28298/ch2charset.htm

  You can use a like WE8MSWIN1252 character set which covers the Spanish also (like many, I know) and a superset of us7ascii

• Changing database character set

  Hi master,
  
  I use oracle database XE on windows XP platform. This is just a test database. I need to import a schema into the database of the XE. but the problem is the character set conversion.
  
  According to the oracle documentation, I tried to change the character set, but it is not worked.it says that ORA-12712: new character set must be a superset of the old character set. It is said
  
  Export file created by EXPORT: V10.02.01 by conventional means
  CAUTION: objects have been exported by < user >, not by you
  import in WE8MSWIN1252 and AL16UTF16 NCHAR character set
  import server uses the AL32UTF8 (possible character set conversion) character set
  
  I have the same import NCHAR character set was made, but when I try to change the character above error is generated.
  
  When I tried to change the character set it gives the above error.
  
  What should I do?
  
  Thanks and greetings

  Please provide the details, how you tried to change the character set database and what character set.

  As indicated in MetaLink Note 260192.1 ("Changing WE8ISO8859P1 / WE8ISO8859P15 or WE8MSWIN1252 (AL32) UTF8'"), AL32UTF8 is not a binary superset of these character sets and therefore conversion includes import/export steps in case you have non-US7ASCII character data in your database.

  The MetaLink note explains how to make the change in detail, but I do not know if it is supported for 10g XE.

  If you can afford it, the easiest way is probably to create/install a new database 10g XE by using the Unicode character database, I think that option when installing 10 g XE.

• Dynamics Processor Calc does not reach more than [100] ESM blocks during the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).

  Hello

  Our environment is Essbase 11.1.2.2 and work on Essbase EAS and components of Shared Services. One of our user tried to execute the Script of Cal of a single application and in the face of this error.

  Dynamics Processor Calc does not reach more than [100] ESM blocks during the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).

  
  

  I did a few Google and found that we need to add something in the Essbase.cfg file as below.

  Dynamics Processor Calc 1012704 fails to more blocks ESM number for the calculation, please increase the CalcLockBlock setting, and then try again (a small data cache setting can also cause this problem, check the size of data cache setting).

  Possible problems

  Analytical services cannot lock enough blocks to perform the calculation.

  Possible solutions

  Increase the number of blocks of analytical Services can allocate to a calculation:

  1. Set the maximum number of blocks of analytical Services can allocate at least 500.
     1. If you are not a $ARBORPATH/bin/essbase.cfg on the file server computer, create one using a text editor.
     2. In the essbase.cfg folder on the server computer, set CALCLOCKBLOCKHIGH to 500.
     3. Stopping and restarting Analysis server.
  2. Add the command SET LOCKBLOCK STUDENT at the beginning of the calculation script.
  3. Set the cache of data large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH parameter.
     • Determine the size of the block.
     • The size of wrestled data.

  In fact in our queue (essbase.cfg) Config Server we have given below added.

  CalcLockBlockHigh 2000

  CalcLockBlockDefault 200

  CalcLockBlocklow 50

  
  

  So my question is if edit us the file Essbase.cfg and add the above settings restart services will work?  and if yes, why should change us the configuration file of server if the problem concerns a Cal Script application. Please guide me how to do this.

  
  

  Kind regards

  Naveen
  

  Yes it must *.

  Make sure that you have "migrated settings cache of database as well. If the cache is too small, you will have similar problems.

  Spot the problem?

  The original dump was expdp, we seek to import with IMP...

  If it is conversely impdp flags it is an exp file - but this round way you get just this random error!

  See you soon,.

• Sometimes, the Firefox doesn't recognize a character set

  Firefox can not decode some English text characters or symbols and instead of characters appear a kind of codes. Just like you would surf the Chinese website without the Chinese character set.

  Like this here

  Why is it so in Firefox? I've never seen what happens in Internet Explorer.

  Pages that use Unicode (UTF-8) format display a small box with the hex code if the character cannot be displayed.
  Which allows you to search the character in a table.

  If you see such a box with hexadecimal code in it, then it means that Firefox cannot map a character to a specific font, and you will need to install a font that covers the affected characters.

  In your case you are missing fonts and font support if it occurs on sites that use the IDEOGRAM.
  
  You will see something similar on Windows XP if you visit pages that use complex scripts (e.g. hindi and Arabic).
  
  Windows XP account very basic language support installed by default.
  
  There are many languages in the world and there are still languages that may require special fonts.
  
  You probably can't read, so it's your choice if you want to install a font for these pages or just accept the small squares with the hex code.

• How to stop people at random me to add and block instantly?

  I get people to randomly add me and when I remove them he gets very annoying to have to go through and block them. I normally get 4-5 a day and Im not really sure where they're getting my name of? Any help?

  Noone you can add if you agree to the request. Contact requests are open design, so that anyone can send a contact request, however they do not add you as a contact if you agree. This is how most of the messaging software and Skype works. Skype is as an open directory anyone can search and find you (if they know how).

  You can however reject and block any communication of the additional requestee. You should also review the tools > settings > privacy and make sure everything is set up as you like.
