Configuring Oracle Database 10g Developer 6i for Arabic and Urdu requires synchronizing character sets across the database, the client registry, and the operating system. 1. Database Character Set Configuration For a database to store Right-to-Left (RTL) characters, its NLS_CHARACTERSET must support them. Best Options: AR8MSWIN1256 (8-bit Arabic/Urdu) for efficiency or for universal support.

Oracle Database 10g is a robust and feature-rich relational database management system that supports a wide range of languages, including Arabic and Urdu. Oracle Developer 6i, a comprehensive development environment, provides a set of tools for building, deploying, and managing database applications. To support Arabic and Urdu languages in Oracle Database 10g using Developer 6i, specific settings and configurations are required. In this article, we will guide you through the process of configuring Oracle Database 10g and Developer 6i to support Arabic and Urdu languages.

| Problem | Likely Cause | Solution | |---|---|---| | Arabic shows as ? or garbage | NLS_LANG mismatch | Set NLS_LANG=ARABIC_EGYPT.AR8MSWIN1256 | | Urdu characters disconnected | Win code page or font | Use Arial + set Windows non-Unicode to Arabic | | Text reversed (wrong direction) | Missing RTL property | Set ORIENTATION=RIGHT_TO_LEFT and JUSTIFICATION=RIGHT | | Cannot save special Urdu glyphs | Database using US7ASCII | Recreate DB with AR8MSWIN1256 or AL32UTF8 | | Cursor jumps incorrectly | Form canvas alignment | Align canvas fields to right edge, set Coordinate System appropriately | | Arabic numbers appear as English | NLS_NUMERIC_CHARACTERS | Set NLS_NUMERIC_CHARACTERS = '.,' but accept digits as-is |

: Change the Windows System Locale to Arabic or Urdu for proper character rendering.

Using AL32UTF8 is often recommended for modern setups, but legacy Developer 6i tools sometimes struggle with Unicode, making AR8MSWIN1256 a common stable choice for Arabic/Urdu. 3. Windows Operating System Settings

NLS_LANG is the "traffic cop" that tells Oracle clients how to convert character data between the client operating system and the database server. It is used by tools like SQL*Plus, exp, and imp. Incorrect configuration is the leading cause of garbage or question-mark data. You should set it on both the database server and each client machine.

When designing modules inside Oracle Forms Developer 6i, properties on individual items must be explicitly modified to accommodate right-to-left typing. Property Palette Rules | | Text displays Left-to-Right | Item Reading

: Set the Form module's direction property to Right-to-Left if the entire application layout needs to be mirrored. Item-Level Properties (Text Items)

Developer 6i relies heavily on the Windows Registry to determine how it interprets and displays data from the database. You must configure the correct NLS_LANG value in the Oracle Home registry key. Locating the Registry Key Press Win + R , type regedit , and hit Enter.

Why? Developer 6i client cannot handle UTF8 reliably for bidirectional text. AR8MSWIN1256 supports Arabic, Persian, and Urdu characters (except a few rare Urdu letters – those can be stored as HTML entities or using AL32UTF8 but will appear broken in 6i).

After implementing these settings, I was able to successfully display and manipulate Arabic and Urdu text in my Oracle Database 10g Developer 6i applications. The text was rendered correctly, and the RTL language support worked as expected.

: If the database was created with an incompatible set (like WE8MSWIN1252 ), it may need to be recreated or altered using:

SELECT parameter, value FROM nls_database_parameters WHERE parameter IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET'); Use code with caution.
