User Guide

When you configure the general setup of a Teradata Database system, the Character Set settings allow you to define the charset that the system uses to communicate with Teradata Viewpoint. The character set definitions are optional. If you do not define them, Teradata Viewpoint uses the Teradata Database system settings.

Character Set Fields Character Set Definition Suggestions
Session The UTF8 session character set is strongly recommended for the Teradata Viewpoint session to ensure end-to-end fidelity of character data by avoiding conversion between character sets.

Teradata Database 14.10 and later: The UNICODE session character set is supported by Teradata Database 14.10 and later.

Teradata Database 14.0 and earlier: Use Non-Unicode session character sets, such as LATIN1252_0A, KANJISJIS_OS, and KANJIEUC_OU, to create Teradata Viewpoint object names that connect Monitor and Console Partitions.

JDBC Flag The JDBC Flag setting is a legacy-support feature to assist the transition away from the unsupported use of Teradata Database to store non-Latin characters in a Latin column, and the unsupported access of non-ASCII in an ASCII session character set. The JDBC Flag option specifies the CLIENT_CHARSET connection parameter, which can be used to override the Teradata JDBC Driver fixed-mapping of the Teradata session character set to the Java character set. The valid values are the actual Java character set names. Here are two examples of valid JDBC Flag settings:
  • Windows-936 from Chinese (PRC)
  • Windows-950 for Chinese (Taiwan)

The default Teradata Database system settings are listed below.
