CICS Scheduled Transaction Sequence

Describes the sequence associated with CICS transactions triggered by a scheduled transaction.

When the region database triggers a scheduled transaction, the following sequence of events occurs:

  1. The region database notifies the cross-region database of the transaction request.
  2. The cross-region database sends the transaction details to the event monitor.
  3. The event monitor retrieves the transaction details from the region database.
  4. The event monitor forwards the transaction details to the dispatcher.
  5. The dispatcher sends the request to the transaction queue on the region database, which handles SEP processing of the transaction.

    From this point on, the scheduled transaction behaves in the same way as an input transaction from a 3270 emulator. See Processing Event Sequence: TN3270 Request for further details.
