information are described below:
DBPATH rollover fails using ODBC when the database server is down (Bug 154923).
Some SJIS code points cannot be properly inserted using the ODBC driver (Bug 154992).

When using IBM Informix ODBC driver to perform distributed transactions using Microsoft Transaction Server, it is necessary to turn off session pooling for the Microsoft OLE DB Provider for ODBC Drivers (MSDASQL). This property can be set in the application by adding the value "OLE DB Services=-4" in the connection string. This will turn off session pooling and autoenlistment in the MSDASQL OLE DB provider, and allows the pooling and autoenlistment to occur in the IBM Informix ODBC driver. For further details regarding this issue, please refer Microsoft Knowledge Base Article #Q269735. (http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q269735)
When a stored procedure with a return value is executed using the IBM Informix ODBC driver, errors returned by the procedure are not returned to the application until a fetch is called on the result set. Error information from stored procedures with no returned values is available immediately following the execution of the procedure.
