Fetch Unit
The Fetch Unit setting only applies to input cards. The Fetch Unit setting defines the number of units of data to retrieve each time a request for data is made to the adapter. Fetch Unit is primarily used when the Fetch As setting is set to Burst although it may also be used in other situations. The default value for FetchUnit is 0.
A specific Fetch Unit value allows you to aggregate, or "batch", a set of physical units (such as messages on a queue) into a logical unit of work. The unit of data is adapter-specific.
