Description

Setting Meaning
0 Fast/Unload requests are executed on a z/OS subtask, that is, not on the Model 204 main task, nor on an MP/204 subtask, nor on a zIIP support SRB.
1 Fast/Unload requests are executed on some "M204 task," that is, either the Model 204 main task, an MP/204 subtask, or the zIIP support SRB. With this setting, a Fast/Unload request will run:
  1. On a zIIP support SRB, if the Online load module is authorized for the Fast/Unload HPO and the M204 HPO products.

    Notes:

    • In order for there to be any zIIP support SRBs, the AMPSUBZ and NMPSUBZ parameters must each be greater than zero.
    • If the conditions for running on a zIIP support SRB are met and the Fast/Unload request is running in a single-user Online, the following parameter settings are recommended:
      • NMPSUBS=0, AMPSUBS=0
      • NMPSUBZ=1, AMPSUBZ=1
      • SCHDOPT=X'62'
  2. Otherwise, on an MP/204 subtask, if the Online load module is authorized for the MP/204 product
  3. Otherwise, on the Model 204 main task.

Note: Under VM/CMS, the FUNMTASK parameter is forced to 1.
