Hello everybody,

I have more than 30 years experience on mainframe from dos to Z/os and scheduled millions applications on it, including end-to-end.
Today on my new client, i arrive on a Z with OPC not configured as a server with unix but i have Unix servers separately with distributed TWS.
On both, the current plan start each day at 11:00 for a production start at 18:30.
When i try to schedule a standard TWS jobstream (monday till friday on workdays), on OPC it's perfect and on TWS Unix if it is before 00:00 all is okay, but if i want to schedule at 7:00 tomorrow, the result is that TWS schedule the jobstream on friday for saturday morning, and if i add freedays in the week with except don't run, it exactly runs on these freedays.
What it's strange is that i find no one example on the net about this nor on any brochure about this problem.
And what is totally extraordinary and against all logics is : if i think "MINUS 1" for everything : i schedule from sunday to thursday with saturday as free day and add freedays calendar with minus 1 free days : it's working perfectly ???
Is anyone has experienced this kind of UFO ???

As far as I remember an OPC connector has to be installed for communication between OPC-TWS.
