Implications of the OSFMIN and OSFMAX Parameters

The values of the OSFMIN and OSFMAX parameters have these implications:

If the values are too low, then TSO commands may incur delays because they must wait in the queue.
If the values are too high, then there may be many OPSOSF servers doing no work. Although this does not affect OSF performance, you may incur the minimal real memory cost of having idle address spaces in your system. An idle OPSOSF server is in a pure OS WAIT; it uses no CPU time. If you are running your OPSOSF server address spaces as non-swappable address spaces, then there is an additional real storage cost. For a description of the OSFSWAPPABLE parameter, see the Parameter Reference.
The value of the OSFMIN parameter can never be higher than the value of the OSFMAX parameter.

Note: The information in this section applies to the OSFTSLxxx, OSFTSPxxx, and USSxxx parameters as well.
