If Teradata Database uses any Site-Defined Client Character Sets, you must copy some files manually to a new location. Site-Defined Client Character Sets are described in Teradata Vantage™ NewSQL Engine International Character Set Support, B035-1125.
- Ask your system administrator or database administrator if there are any Site-Defined Client Character Sets on the system and whether they need to be saved for future use.
- Inspect the files in the /opt/teradata/tdat/tdbms/starting_version/etc directory (where starting_version is the previous Teradata Database version) to see if there are any files that begin with "map."
- Now inspect the files in the /opt/teradata/tdat/tdbms/new_version/etc directory (where new_version is the new Teradata Database version) to see if there are any files that begin with map.
- If any of the map files in the /opt/teradata/tdat/tdbms/starting_version/etc directory are not present in the /opt/teradata/tdat/tdbms/new_version/etc directory, copy the map files into the new directory.
