Oracle GoldenGate supports the conversion of column data between character sets when the data is contained in the following column types:

• Character-type columns: CHAR/VARCHAR/CLOB to CHAR/VARCHAR/CLOB of another character set; and CHAR/VARCHAR/CLOB to and from NCHAR/NVARCHAR/NCLOB.

• Columns that contain string-based numbers and date-time data. Conversions of these columns is performed between z/OS EBCDIC and non-z/OS ASCII data. Conversion is not performed between ASCII and ASCII versions of this data, nor between EBCDIC and EBCDIC versions, because the data are compatible in these cases.

  Note:

  Oracle GoldenGate supports timestamp data from 0001-01-03 00:00:00 to 9999-12-31 23:59:59. If a timestamp is converted from GMT to local time, these limits also apply to the resulting timestamp. A value of zero month, zero day field, or an all zero date value isn't supported. For example, values such as 0000-00-00 00:00:00, or any date value that includes a zero month or zero day field isn't supported.

Character-set conversion for column data is limited to a direct mapping of a source column and a target column in the COLMAP or USEDEFAULTS clauses of the Replicat MAP parameter. A direct mapping is a name-to-name mapping without the use of a stored procedure or column-conversion function. Replicat performs the character-set conversion. No conversion is performed by Extract or a data pump.
