Using different connection modes to receive events

There are two connection modes on top of the transport mechanism, connection-less (CL) and connection-oriented (CO). Events processed by the Probe for Tivoli EIF are not processed in the order in which the events are sent. This may effect custom triggers that process events in a specific sequence or order.

Connection-less

In connection-less mode, the source establishes a TCP/IP connection to the receiver, sends one EIF message and immediately closes the connection. If the sender is required to send another message, it establishes a new TCP/IP connection to the receiver, sends one EIF message and again immediately closes the connection.

Connection-oriented

In connection-oriented mode, the source establishes a TCP/IP connection to the receiver, sends an EIF message, after which the connection remains open. If the sender is required to send another message, it simply uses the already established connection. In either case, the TCP/IP protocol takes care of assembling the data stream in the correct order and resending packets if there are problems during transmission.
