Mark,
?
It is not just XNET, it is the nature of the beast.? When a CTC device has an i/o in progress, the entire channel is busy; if there are other devices on the channel, whether they are other CTCs or any other device, they will be unable to do i/o or receive interruptions during the CTC i/o.
?
So if you are using 500 for XNET, then I would recommend you put RSCS's CTC on 600 or some other channel.? But if you are aware of the possible reduction in throughput on a CTC channel, then yes you could also put RSCS's CTC on channel 5.
?
The other thing is that our systems are small and generally just single user, so the number of i/os issued by XNET across the channel isn't going to be much of an impact.? XNET doesnt do any "heartbeat" i/o, so if you are not doing anything at your 3270 terminal dialed to XNET, then there is no idle-time CTC i/o.
