When you use the new configuration parameter timestamp_ms_support, consider the following conditions:
When timestamp_ms_support equals 0, Sybase TIME datatype is accessible, but the millisecond portion of an Oracle TIMESTAMP contains 000 (zeros).
When timestamp_ms_support equals 1, Sybase TIME datatype is able to insert, update, delete, or select the millisecond portion of an Oracle TIMESTAMP.
When DCO 12.6 interoperates with Adaptive Server® Enterprise Component Integration Services (ASE/CIS), the version of ASE/CIS must be 12.5.1 ESD#2 or later to use the timestamp_ms_support configuration option. This is due to changes that were made in ASE/CIS 12.5.1.
When DCO 12.6 interoperates with an application other than ASE/CIS, the timestamp_format configuration setting must include the milliseconds (..SSXFF) if the millisecond portion of the time is desired, and the timestamp_ms_support parameter must be equal to 1.
