NLS_LANGUAGE and NLS_TERRITORY Definitions Changed in 10g, 11g and 12c Versus 9i and lower (Doc ID 292942.1)

Last updated on FEBRUARY 03, 2019

Applies to:

Oracle Database - Enterprise Edition - Version 10.1.0.2 and later
Oracle Database - Standard Edition - Version 10.1.0.2 and later
Oracle Database - Personal Edition - Version 10.1.0.2 and later
Information in this document applies to any platform.

Purpose

Changes have been made to the content in some of the NLS_LANGUAGE and NLS_TERRITORY definition files in Oracle Database 10g, 11g and 12c when compared to 9i and lower.
These updates are necessary to correct the legacy definitions which no longer meet the local conventions in some of the Oracle supported languages and territories. So some changes were made to correct the definitions used by Oracle's language and territory settings.
It's however possible to use with 10g and higher "9i behavior" definitions. This note includes detailed steps on how to enable this.

Scope

Anyone upgrading from 9i to a higher version.
