MLS Installation in 11i/R12

Introduction to NLS/MLS
NLS: National language support. Being able to run an application in 1 language. This language can be any supported language.
It basically means the ability to run an Applications instance in any one of the supported languages (other than American English), including certain region/territory specific numeric and date formats. Only the customer-facing components (i.e. the user-interfaces, lookup tables, online documentation etc.) are translated. The underlying logic stays the same as that for American English.
MLS: Multiple language support. Being able to run an application in more then 1 language at a time.
It means the Application can be successfully run in more than one language on the same Oracle Applications instance.

MLS in Release 11iIn Release 11i, the translatable fields moved from the base table to the translation (_TL) table.So all tables containing translatable strings/fields have a related translation table ( _TL table).
(Though it was started in Release 11.0, only FND, ICX and AK had this functionality. The other modules did not.)
For example, the FND_CONCURRENT_PROGRAMS table NO longer contained the following columns:
instead, these columns were moved to the FND_CONCURRENT_PROGRAMS_TL table.

So the _TL table contains one record for each language i.e the translated string for each language.
Also “ _VL” view has been introduced for the “_TL” table, which allows to select the data based on the session language without running the risk of returning more rows then expected.
So view FND_CONCURRENT_PROGRAMS_VL will return rows as per the session language settings.

A number of profile options have been introduced, which force an “ALTER SESSION”, setting the specified language, numeric character and date format etc for the current user only.

When a user does signon, the profile options that will influence the NLS characteristics for his session are:

So what happens when you signon is that the profile options are being read and the corresponding NLS variable will be set using an ‘alter session’ command.
All translatable files reside in a subdirectory which has the language code incorporated in the name (e.g. $AP_TOP/reports/EL, $GL_TOP/forms/F etc.) .

  • Forms, Reports, Messages & Seeded data are translated
  • FND_LANGUAGES table shows which languages are installed, and which is the base language and which are non-base languages (Installed Languages)

Installation Introduction

The Translation Synchronization patch feature provides a quick way for you to synchronize your existing translations with the American English file versions on your Applications instance. By applying just one patch for each language, you will be able to bring your translations up to your current Applications patch level. You can also choose to get the latest translations to bring your translations up-to-date.
The basic concept involves preparing a single manifest file for your Applications instance. This manifest reflects the language software content for all the active languages on your current Applications system. The manifest will be used to generate customized patches for your system.
This feature reduces the installation time and complexity for synchronizing language installations. It also provides a simple way for you to update your existing translations.

Pre Installation Steps

Prerequisite Patches
a.If you are not on AD mini-pack I (11i.AD.I.2) or later, apply the latest
AD mini-pack from OracleMetaLink. AD patch level report is generated by the following command:
sqlplus /
b.Apply update 5837664. This update delivers the latest tool for generating manifest file as mentioned in section 3. The latest tool will generate a single manifest file with all the active languages in an instance. Download this update and review its readme for instructions to apply it.

Character Set Support
The database character set must support the New Language.If the database is not in a character set that supports the new Language, the database character set as well as the character set in the APPL_TOP must be converted.

Check Space in APPL_TOP
It requires approx 5 GB for each new lnguage. So, check the space available in $APPL_TOP
$ cd $APPL_TOP
$ df –k .

Installation steps

  1. Change Language Configuration
    Use the OAM License Manager to activate a new language(s).

  2. Maintain Multilingual Tables

What it does: It will do the following:
• Create a record with SOURCE_LANG = ‘US’ for each of the languages that doesn’t have a records in the _TL table.
• Update all records where SOURCE_LANG LANGUAGE, defaulting the translatable fields to the value found under the SOURCE_LANG
Steps : From the AD Administration main menu, choose the Maintain Applications Database Objects menu, and select the “Maintain the multi-lingual tables” task as described below:
1. Run adadmin
2. Select Option 2 (Maintain Applications Database Objects menu)
3. Select Option 6 (Maintain multi-lingual tables)

3.Maintain Snapshot Information

4.Generate and Upload the Manifest of Customer-specific Files
Log on to your Applications’ administration node as the APPLMGR user and source the APPL_TOP environment file. Use the manifest generation tool to generate customer-specific manifest file by executing the following command:

perl $AD_TOP/bin/

The manifest generated from the tool is in the format :


The manifest contains all of your active languages. You do not need to run the tool for each individual language.
Once the manifest is generated, you can go to (use your OracleMetaLink username and password).
Follow the instructions on the screen to upload the manifest file. A Translation synchronization patch will be generated specifically based on your manifest for each of your active languages. The patch will synchronize the language file versions and American English file versions in your Applications instance. If you select the option to get latest translations, the patch will also bring your translations up-to-date.

If your current translations are already up-to-date and in sync with your American English file versions, you will be notified by e-mail that there is no need to apply Translation Synchronization patch.

5.Applying Translation Synchronization Patch

Once the customer-specific Translation Synchronization patch is ready, you will receive an e-mail stating its availability. You can then download the patch from OracleMetaLink. Follow the instructions in the README file to apply the patch.
A Merged Translation patch may be generated if full translations are not available.
You can merge multiple language Translation Synchronization Patches and apply the single merged patch to your system. See Oracle Applications Patching Procedures guide for information about merging NLS patches.

Post Installation Steps

  1. Run Autoconfig

  2. Compile and Genarate from adadmin
    • Compile the flexfield data
    • Generate message files
    • Generate forms and libraries
    • Generate Reports

Install font files on the HTTP Server (Conditional)
To enable the Oracle UIX Dynamic Image technology to successfully generate images, the required font files to support the active Applications languages must be available on the HTTP Server node. Oracle Applications provides Unicode font files in the /resource directory and should be installed on HTTP Server.
To satisfy all Applications supported language font requirements including specific East Asian language font requirements, there are actually five fonts supplied: Generic font without East Asian languages, Japanese font, Korean font, Simplified Chinese font and Traditional Chinese font. The fonts are called ‘Albany’ and they are proportional fonts in ttf format. Disk space required for the font files is approximately 75MBytes.
• Copy the font files to the Java default font directory for the external JDK on the HTTP Server node.
$ cp /resource/ALBAN*.ttf /jre/lib/fonts
• Remove Image Files from Cache Directory
Remove all existing non-English language image files from the image cache directory.
$ cd $OA_HTML/cabo/images/cache
$ cd
$ rm *.gif *.imx

  1. Restart the Apache service on the HTTP Server node for the updates to take effect.
