How are programs reinitiated under CICS ?
Answer / guest
Automatic transaction initiation (ATI)
When the queue has been emptied, a new ATI cycle begins.
If the destination is a terminal, the fact that QZERO has
not been reached means that trigger processing has not been
reset and the same task will be reinitiated later.
In addition, the task is not reinitiated if a resource
(terminal, program, or transaction) is not available. If
the trigger level of a queue is zero, no task is
automatically initiated.
