Type 1 Fallback Mappings and Multibyte Data

Type 1 Fallback Mappings and Multibyte Data

For a PowerCenter session that writes data in a non-IBM code page to a z/OS or i5/OS target system, you might achieve more accurate character conversions by enabling type 1 fallback mappings. To enable type 1 fallback mappings, define USE_TYPE1_FALLBACKS=Y in the DBMOVER configuration file.
For example, if a PowerCenter session writes data from a SQL Server data source to a PowerExchange z/OS target, different Unicode values are used for punctuation characters such as the half-width tilde and the half-width dash. If you do not enable type 1 fallback mappings, this situation can result in substitution characters on the z/OS target. However, if you define USE_TYPE1_FALLBACKS=Y in the DBMOVER file on the Linux, UNIX, or Windows system, the z/OS target receives the closest available match instead of the problem substitution characters.
