Oracle database encoding options

If you plan to install Oracle, it is important to consider the character set for the data that you plan to store in your database when you configure the database for use with IBM Curam Social Program Management.

For Oracle, there are two parameters to consider: NLS_CHARACTERSET and NLS_LENGTH_SEMANTICS.

• The NLS_CHARACTERSET parameter details the allowable character set of any data that is loaded to the database, generally AL32UTF8 is recommended by Oracle.
• The NLS_LENGTH_SEMANTICS determines how Oracle interprets length specifiers on CHAR and VARCHAR columns. To handle supplementary characters, for example, ß in German, where the storage of the character would be 2 bytes and might overrun the length of a defined column; set the NLS_LENGTH_SEMANTICS parameter to CHAR. This setting directs the database to size columns with a character length rather than byte length.
