The CA IDMS DDS startup procedure is identical to the standard DC/UCF startup procedure. When a node is started up, it transmits messages through its ports to the other nodes to which it is connected. If the other node is active, a connection is established and information is exchanged between nodes. This information is stored internally as tables maintained by CA IDMS DDS.
Each node knows the status of neighbors
As nodes sign on or off, these tables are updated to reflect the changes in the network. At any point while the network is operating, every node in the network knows the status of all the nodes to which it maintains direct connections.
The following illustration shows the sequence of events that takes place when a CA IDMS DDS network is started.
