## Description

Oracle’s `NLS_LANG` parameter sets the language, territory, and character set that the iProcess Engine uses to communicate with the Oracle database. The iProcess Engine requires that `NLS_LANG` uses an 8-bit character set.

`NLS_LANG` is defined in the following Windows registry subkey:

Oracle Version | Key
Oracle 11g | `RegistryLocation``\ORACLE\KEY_``ORAHOME` where `ORAHOME` is the Oracle home name.

where `RegistryLocation` is `\HKEY_LOCAL_MACHINE\Software`

Note | You can also set `NLS_LANG` as a System or User environment variable (using System in the Control Panel window). However, if you do this the environment variable setting is used for ALL Oracle homes and takes precedence over any parameters set in the Windows registry. Oracle recommends that you use the Windows registry to set `NLS_LANG` unless you have a specific requirement to use an environment variable.

## Node Cluster

`NLS_LANG` must be set to the same value on the master server and on each slave server.

## Procedure

To set `NLS_LANG`, complete the following steps:

| 1. | Set the `NLS_LANG` value to use an 8-bit character set component (`charset`).

| 2. | If you are using a TNS connection, make sure that the character set component (`charset`) of the `NLS_LANG` value for the Oracle client matches the character set component of the `NLS_LANG` setting on the Oracle database.

The format of the NLS_LANG string is:

`NLS_LANG =` `language_territory.charset`

## Example

`NLS_LANG=American_America.WE8ISO8859P1`
