Complete Installation and Upgrade Information for Software AG Products : Installing Software AG Products : Creating and Dropping Database Components : Preparing for Database Component Creation : Set Database Options : Oracle
For your products to function properly, you must set the NLS_LENGTH_SEMANTICS initialization parameter to BYTE.
Your products use BYTE rather than CHAR semantics because BYTE is the default configuration of Oracle database and is used by most Oracle users. If you try to use your products with CHAR semantics, unexpected results might occur. For example, since CHAR semantics allow storage of longer data than BYTE semantics (for Japanese, varchar(12 byte) takes four characters in UTF8 while varchar(12 char) takes 12), using CHAR semantics could cause the buffer in some products to overflow.
