Optimized message transfers

HCL OneDB™ ESQL/C provides a feature called optimized message transfers, which allow you to minimize message transfers with the database server for most HCL OneDB ESQL/C statements.

HCL OneDB ESQL/C accomplishes optimized message transfers by chaining messages together and even eliminating some small message packets. When the optimized message transfer feature is enabled, HCL OneDB ESQL/C expects that SQL statements will succeed. Consequently, HCL OneDB ESQL/C chains, and in some cases eliminates, confirmation messages from the database server.
