HPL usage tasks
Reorganize computer configurationIf you are not changing the table schema, use a No-Conversion Job to unload and load when you need to reorganize the configuration of your computer or change to a different computer. The no-conversion mode is the fastest means of performing an unload job or a load job, because rows are unloaded in HCL Informix® internal format with no conversion and reloaded in the same fashion.

Reorganize computer configuration

If you are not changing the table schema, use a No-Conversion Job to unload and load when you need to reorganize the configuration of your computer or change to a different computer. The no-conversion mode is the fastest means of performing an unload job or a load job, because rows are unloaded in HCL Informix® internal format with no conversion and reloaded in the same fashion.

Restriction: You cannot use a No-Conversion Job when the source and target computers use different internal byte representations. For information about the byte-order type, see The Machines window.

For information about preparing for a no-conversion unload/load with ipload, see Using the No Conversion Job option. To set no-conversion mode when you are using the onpload utility at the command line, use the -fn option. For more information, see The onpload utility.
