Known problems

At the time of publication, the following problems were known:

When you use the HCL Informix® ODBC Driver to perform distributed transactions that use the Microsoft Transaction Server, 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. Setting the property turns off session pooling and autoenlistment in the MSDASQL OLE DB provider, and allows the pooling and auto enlistment to occur in the HCL Informix ODBC Driver.
