We have a PC-.NET application and an eServer as a File Server connected over OLEDB/IBMDA400. We have very poor performance. In the trace (ibmda400.trc), I've seen that the eServer spent most of the time for the conversion of data fields sending them back to the PC. Is ODBC the better solution? How can I force the conversion?
I don't think you will find the performance of ODBC better then the ADO. We never came across performance problem resulting from conversion of data.
* Check the SQL statements to be optimized.
* Use blocked statements in ODBC (Click here for a good resource)
* Use the ODBC performance tab to define packages usage.
