Setting NLS_LANG Environment Variables

To set NLS_LANG environment variables:

Define values for these variables in the same way you define other environment variables on your base operating system, keeping in mind platform-specific rules such as path length, etc.

For example, to set NLS_LANG for Microsoft Windows:

  1. From the Start Menu select Run.
  2. Type 'regedit' and click OK to open the Registry Editor.

Note The Windows registry is highly sensitive to changes. Only change environment variables if absolutely necessary. If you make a mistake, click Cancel and restart.

  1. Expand the HKEY_LOCAL_MACHINE node, then expand the SOFTWARE node.
  2. Click ORACLE to display the Oracle environment variables in the right panel of the Registry Editor.
  3. Double-click the NLS_LANG environment variable.
  4. Type the new value for NLS_LANG in the Value data text box and click OK.

Note: If you want to use any NLS feature, you must at least set NLS_LANG so that the product can locate the NLS components.
