Description
This parameter must have a numeric value between 0 and 64, inclusive. If set to 0 (the default), the Fast/Unload User Language Interface is not able to initiate requests because there can be no Fast/Unload tasks started to run them. A number greater than 1 indicates the maximum number of Fast/Unload tasks that are to be attached to the Online, so the maximum number of Fast/Unload User Language Interface requests that can run concurrently — if this limit is reached, additional requests are queued until a request completes.
The advantage of setting this value to a larger number is the potential for increased concurrency. The disadvantage is that if more requests want to run simultaneously than the number of available processors to run them, some of the requests could suffer severe performance degradation, to the point that they might complete significantly faster if they run serially rather than concurrently. In general, unless a site has many idle processors, it is probably unwise to set this parameter greater than 2.
If FUNTSKN is set to a non-zero value, Model 204 will try to load the program indicated by the FUNPGM parameter FUNPGM at Online initialization.
If a site is not authorized for Fast/Unload User Language Interface, this parameter will have no effect.
