NLS Functionality

NLS functionality in the TIBCO Object Service Broker environment is dependent on the definition of a locale and a code page.

The locale and code page together function as an ordered pair of identifiers (locale.codepage). They represent the cultural conventions and code page properties used within the locale Data Object Broker (referred to as SELF) and when communicating with one or more peer Data Object Brokers (referred to as REMOTE).

Locale

The locale is the portion of a user’s environment that is sensitive to cultural conventions of a particular language, country, or territory. The value defined for the locale establishes the language used for data manipulation and storage within a Data Object Broker.

Code Page

The code page value identifies the character set encoding to be used. The notion of the code page value is used in several contexts:


Communication code page	This is associated with internode peer-to-peer user character data requests.
TDS code page	This is associated with the TIBCO Object Service Broker TDS character data fields.
System code page	This is associated with the TIBCO Object Service Broker Execution Environment (for example, code page IBM‑037) and is used to encode object and field names in the metadata.

Locale Specifications

In general, the specification of a locale determines such things as:

•

The character set

•

An appropriate message catalog

•

National/regional conventions regarding upper/lowercasing

•

Collation

•

Date format

•

Time format

•

Monetary symbols and formats

Folding Rules

For NLS support, you set a locale.codepage value. The locale setting currently affects only folding operations. For each valid locale value, the set of lowercase characters that are folded is defined in the following table:


Locale	Lowercase Characters Mapped to Uppercase
ENGL	a-z
ENGB	a-z
CDNB	a-z â à ç é ê ë è î ï ô û ü ù
DANS, NORS	a-z å ø æ
DEUT	a-z ä ö ü
ESPA	a-z ñ
FRAN	a-z
ITAL	a-z
PORT	a-z ã ç õ
SCHW	a-z ä ö ü
SUOM, SVEN	a-z ä å é ö

For example, “é”, listed in the table for the CDNB locale, is folded to “É”, and “í”, not listed in the table, results in “í”.

Restrictions and Unsupported Items

There are some restrictions, as well as some NLS items that are not supported. Refer to General Restrictions and NLS Items Not Supported for more information.
