This solution handles IMS startup and termination.
A link between IMS and INCONTROL products is established by defining IOA prerequisite conditions that reflect IMS’s status (up or down). Specifying these conditions as prerequisite IN conditions in IOA definitions makes processing dependent upon IMS being up or down.
Note: While startup or termination is in process—but not yet completed—the IOA environment considers IMS as both "not up" and "not down." Therefore, IMS not being up is not necessarily the same as a IMS down status and vice versa.
IOA IMS prerequisite conditions must also be updated at time of IPL to indicate that the production IMS subsystem is down (see SolveWare Initialization.)
