ATI is the CICS® process that allows a transaction to be scheduled against a specified terminal.
An ATI request from an EPI application can start a CICS server transaction on any EPI installed terminal.
Either the user application or the CICS systems administrator can enable or disable automatic initiation of transactions for a terminal. The default state is disabled. If ATI requests are enabled and an ATI request is issued in the CICS server, the request is started when the terminal is idle. Any ATI requests issued while ATI requests are disabled are queued, and started when ATI requests are next enabled. ATI requests for a terminal are queued while a transaction is in progress on that terminal.
