Open Client 15.7 supports caching row format information, which allows client applications to request data servers to not send the row format information each time a dynamic SQL statement is invoked. Row format caching reduces network traffic between the data server and client applications, thereby improving system performance.
By default, row format caching is enabled in Open Client 15.7. To disable it, set the CS_CMD_SUPPRESS_FMT response capability to CS_FALSE. Use ct_cmd_props() to check and set the value of CS_CMD_SUPPRESS_FMT.
To determine if the server supports row format suppression, check the value of CS_RES_SUPPRESS_FMT using ct_capability().
