Starting an IMS network
Before a session with IMS can be established for any workstation VTAM®, NCP, controllers, and logical units must be active.
Specifically, the following components must be active:
- VTAM and NCP must be active.
- Controllers and logical units that are not activated automatically by VTAM must be activated with a VARY command by the VTAM network operator.
- Controllers must be powered on, and appropriately configured, initialized, and activated for VTAM and NCP.
