Is it possible to change NLS_LANG settings on the server after installation Oracle 11.2 XE? (I am not thinking about alter session.) As you know one can not choose db characterset nor nls_lang while installing this product.

Since my previous version of Oracle 10 XE had differenet NLS_LANG setting I would like it to be the same.


Yes, you can change NLS_LANG on server and session level. Changing database characterset is almost impossible when the original characterset is not US7ASCII.

To change NLS_LANG:

  • Environment variable NLS_LANG
  • System environment variable NLS_LANG
  • Use registry HKLM\software\oracle... and add string value.

Remember to use quoting when necessary on Windows when there are spaces in the region.

  • Tnx. My charachterset is AL32UTF8. I wil try as you said. Tnx once again.
