Defining NLS_LANG in the Microsoft Windows Registry

Note: If NLS_LANG is not defined, it defaults to AMERICAN_AMERICA.US7ASCII and must be changed to a value that Server uses.

To change the NLS_LANG setting using the Microsoft Windows Registry Editor:

  1. Click Start > Run. The Run dialog box opens.
  2. Type regedit, and then click OK.
  3. Edit the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\homeID where homeID is the unique name identifying the Oracle home.
