FICON Tape Write Timer defines a time limit for pipelined write chains. This value is be
specified in milliseconds (ms). If a pipelined write chain takes longer than this value to
complete, the ending status for the next write chain will be withheld from the channel. This
limits processing to what the network and device can support. Too small a value limits
pipelining performance. Too large a value results in too much data being accepted for one
device on a path. The range is 100-1500.
-
FICON Tape Max Write Chain defines the maximum amount of data that can be contained
in a single CCW chain. If this value is exceeded, emulation is suspended. The range is
1,000,000 to 5,000,000 ms.
-
FICON Oxid Base defines the base value of an entry pool of 256 OXIDs supplied to
emulation generated exchanges. It should fall outside the range used by FICON channels
and devices to avoid conflicts. The range is 0x0000 to 0xF000.
