Set Up National Language Support (NLS)
If you plan to use languages other than American English in your installation, read the information in the Oracle Applications NLS Release Notes, andcomplete the necessary steps for installing the translated software.
STEPS :
1) Complete the tasks in the Oracle Applications NLS Release Notes
2) Activate the additional languages via the License Manager utility (within Oracle Applications Manager)
3) The multilingual tables must be updated for the activated languages. Go to the AD Administration main menu, choose the 'Maintain Applications Database Entities' submenu, and run the 'Maintain Multi-lingual Tables' task.
4) Install the relevant NLS software for all the active languages, to lay down the NLS translated files into the APPL_TOP.
5) Use the Translation Synchronization Patch Utility to synchronize the languages with the American English patch level. This step is needed in case any
American English patches were applied after Rapid Install was run.
