Specifies the number of communications arbiter system jobs that are available to process work for controllers and devices. Work for controllers and devices includes input/output requests that are sent to devices and events related to making devices available for use.
The following are possible options:
No communications arbiter jobs. The system arbiter (QSYSARB) and QLUS system jobs perform the work that the communications arbiter jobs normally do. This setting should only be used if IBM® service recommends it.
Indicates the number of communication arbiter system jobs that are started.
The system computes the number of communication arbiter system jobs. This is the recommended setting.
